Now, it's time to shed light on the less-discussed but equally vital aspect of batch processing: the task-oriented approach, specifically the role of batchlets in Jakarta Batch jobs. We'll also explore how to effectively monitor and manage batch job lifecycles to maintain efficiency and reliability.

In this podcast episode, we’d like to invite you to listen to the conversation we recently had with Ken Fogel. Ken is a well known expert in Java and Jakarta EE industry, he’s been working with Java for over 20 years.  Unsurprisingly, he is also a Java Champion, and a Java Community Process Executive Committee member. He is an active conference organizer, very prominent and active in the Java, Java EE and Jakarta EE community.

So there’s no wonder why we had to invite him to our podcast!

Java’s Ahead-of-Time (AOT) native compilation, as seen in frameworks like GraalVM, boasts rapid startup times and lower memory usage. However, for Jakarta EE application developers, the practical benefits of these advantages often don’t translate into substantial economic or technical gains. This leads to questioning the viability of investing resources into adapting existing Jakarta EE applications for GraalVM compatibility.

It's time for the November Payara Monthly Catch! Our monthly news roundup ensures you get the best news of Java, Jakarta EE, MicroProfile, and open source. 

Let's have a look at the most interesting and important news from last month.

Cloud deployment refers to the process of hosting applications on a remote server infrastructure, accessible over the internet. This paradigm has revolutionised software development, offering immense scalability, flexibility, and efficiency. Traditional deployment methods have evolved to embrace modern cloud environments, ranging from Infrastructure-as-a-Service (IaaS), where you manage servers but not physical hardware, to Platform-as-a-Service (PaaS) and Software-as-a Service (SaaS) solutions, which abstract much of the server management and maintenance tasks.

Continuing from where thelast blog post left off, let's delve deeper into the intricacies of configuring the chunk in Jakarta Batch. As we've seen, a chunk represents a set of items to be processed as a batch. Now we will explore how to control this process, manage potential errors, and ensure efficient execution.

In a world where technology never sleeps, staying ahead is not just an advantage; it's a necessity.  This is especially true for organisations running enterprise-level applications on Java EE 8 through  Payara Enterprise 5. While this platform has undoubtedly served you well, the release of Jakarta  EE 10 and Payara Enterprise 6 marks the beginning of a new era in Enterprise Java development. 

In the dynamic world of software development, efficiency and speed are key. This is where Payara Starter, our new code scaffolding tool, comes in. Designed to streamline and simplify the initial setup process, Payara Starter helps developers like you kickstart your Jakarta EE projects with ease, whether you prefer Maven or Gradle build systems.

Garbage collection is a cornerstone feature in the Java Language. It automates memory management by reclaiming memory occupied by objects that are no longer in use, freeing you the developer up from manual memory allocation and deallocation tasks. This feature is vital for preventing memory leaks and ensuring that applications run efficiently over time.

Deploying Jakarta EE applications to the cloud can be a complex task if you are using traditional deployment options like containers, Kubernetes or other such options, but not with Payara Cloud. Uploading a Jakarta EE binary artefact (.war file) and deploying it to the cloud can be achieved in four straightforward steps. They are:

Java's journey towards fostering more expressive and efficient code has taken a remarkable leap with the advent of Record Patterns, encapsulated in JEP 440. This feature, previewed in both Java 19 and Java 20, is now a part of the language from Java 21, marking a significant stride towards reducing the verbosity traditionally associated with Java language. In this post, we will delve into the essence of Record Patterns, take a look at its benefits, and explore how it fits in with the existing pattern matching capabilities of Java.

In the world of programming, stepping stones are crucial for novices to transition into proficient developers. This journey often begins with understanding the syntax and semantics of a given programming language. Java, being one of the popular programming languages, has always aimed to be an effective medium for both novices and experienced developers. The recent release of Java 21 introduced a core feature, known as Unnamed Classes and Instance Main Methods through JEP 445, aimed at simplifying the learning curve for new programmers, making it easier for them to write their first program without much fanfare and verbosity.

For this second episode of the Payara Podcast,Rachel Stephens,Senior Analyst at RedMonk (the developer-focused industry analyst company) and Steve Millidge,Payara Founder and CEO, discussed the case of Hashicorp.

Hashicorp, the vendor of Vagrant, Terraform and other deployment-automation tools, made a controversial change from Free and open source (FOSS) status to a Business Source License, in August 2023. 

As the leaves take on a golden hue and the cool breeze of October sets in, we're thrilled to bring to the table the latest iteration of the Payara Platform. The October 2023 release features 3 bug fixes, 9 component upgrades, 1 security fix and 1 improvement for Payara Enterprise 6.7.0. Payara Community 6.2023.10 also features 4 bug fixes, 9 component upgrades, 1 security fix and 1 improvement.

Devoxx Belgium 2023, the premier Java developer conference, held in Antwerp, Belgium is an event we eagerly anticipate. As representatives of Payara, a sponsor of the conference, we had the privilege of attending this year's gathering, which took place at the iconic Kinepolis Antwerpen Cinema.

Pattern Matching for switch, introduced in Java 21 via JEP 441, marks a significant enhancement to the Java programming language, offering a more expressive and compact way to handle complex decision blocks. This feature extends the existing switch construct by allowing patterns in case labels, thus facilitating more concise, readable, and safe code when dealing with multi-way comparisons​​.

Java 21 introduces the Foreign Function and Memory (FFM) API, which allows Java programs to interoperate with code and data outside the Java runtime. Java operates within a managed environment known as the Java Virtual Machine (JVM). The JVM serves as an abstraction layer between the executing Java code and the underlying hardware and OS. One of the core design principles behind the JVM is to provide a secure and isolated environment for Java applications to run. This isolation is beneficial for several reasons, including security and stability; it mitigates risks such as unauthorized access to system resources or memory corruption, which could lead to vulnerabilities like buffer overflows.

In the ever-evolving landscape of enterprise applications, staying updated with the latest technologies is not just an option—it's a necessity for competitive advantage. The release of Jakarta EE 10 brought forth a myriad of enhancements that can significantly improve the scalability, security, and performance of your enterprise applications. But how do you make the transition smoothly? What are the best practices and strategies for upgrading?

In this recorded webinar tutorial - watch here -  we guide you through the essential steps and considerations for a successful upgrade. We will delve into the new features and improvements introduced in Jakarta EE 10 and why they make a compelling case for the upgrade.

Developers use MySQL databases in every corner of the world to create cloud-based applications. As they continually look for tools that offer better scalability, performance, and flexibility, many are pairing MySQL with the JSON data format.

Combined, these provide a wealth of benefits for developers. We’re going to briefly examine the ins and outs of MySQL and JSON to get you up to speed, then take a look at some of the things you can achieve using them together.

With Java 21 released today and Jakarta EE 11 slated for release in Q1 of 2024, the landscape for Java development is evolving rapidly, particularly in the cloud-native space. Although these two are not being developed together, they are intrinsically linked: Jakarta EE 11 will have Java 21 as its base Java SE version. This blog post will explore what these two significant releases bring to the table individually and how they can collectively enhance cloud native Java development.

We are excited to announce the latest releases of the Payara Platform: Enterprise 6.6.0 and Community 6.2023.9. Payara Platform Enterprise 6.6.0 comes with 2 security fixes, 2 bug fixes, 5 component upgrades and 3 improvements. Payara Platform Community 6.2023.9 also comes with 2 security fixes, 2 bug fixes, 5 component upgrades, and 3 improvements. 

For Payara Enterprise users, Payara Platform 5 is still updated! Payara Platform Enterprise 5.55.0 is out this month. 

Are you a Jakarta EE Developer? Are you looking to level up your cloud deployment? You have options! 

In this technical webinar, our expert Luqman Saeed talks you through 3 key options for your cloud deployment with Jakarta EE:

☁️Docker Containers to Azure Web Apps
☁️Jakarta Runtime installation on a virtual machine and app deployment
☁️Fully managed Jakarta EE cloud deployment runtimes

This is also a great webinar if you are curious about Payara Cloud as we are also discussing many different cloud deployment options- if you have heard about our new fully managed cloud native application runtime for Jakarta EE, this your chance to see exactly how it works. 

One of the most daunting tasks organizations face is keeping pace with fast evolving technological landscapes, while ensuring existing applications remain robust and functional. If you're still running applications on Java EE 7/8,  the release of Jakarta EE 10 sets the upgrade clock ticking. Of course you can keep running such applications with a Payara Enterprise 5 plan. However, if you need to upgrade to take advantage of the many new features in Jakarta EE 10, then read on!

So, you're a Java developer, or maybe you're aspiring to be one. Either way, you've probably faced the challenge of managing multiple versions of Java on your machine. One project requires Java 8, but another needs Java 11, yet another requires Java 17. The open-source library you're keen on contributing to needs yet another version. What do you do? You start juggling environment variables, and before you know it, your system is a tangled mess of configurations. Not fun, right?

And let's not even get started on the difference between JRE and JDK. It's easy for beginners to get confused about the distinction between the two. The JRE (Java Runtime Environment) is sufficient if you just want to run Java applications, but if you're going to be developing them, you'll need the JDK (Java Development Kit). The JDK includes everything the JRE has, plus additional tools and utilities for developers like the Java compiler, or javac.

Tired of all this complexity? Let me introduce you to SDKMan!, a version manager that streamlines the process, making it a breeze to manage multiple Java versions on your machine. Not just Java, SDKMan! can be used to manage a lot more kits and tools such as Maven. In this blog post however, we see how to use SDKMan! to effortlessly manage different versions of Java on the same machine. 

For this first ever episode of Payara Podcast, we had a chat with Rachel Stephens, Senior Analyst at RedMonk (the developer-focused industry analyst company) and Steve Millidge - Payara Founder and CEO. 

We talked about open source, focusing  on using it in the context of enterprise. We talked about public perception of open source, common myths surrounding the use of open source technologies for enterprise businesses, security aspects of using open source and much more.

JSON (JavaScript Object Notation) has become the de facto standard for data interchange in modern web applications. Its simplicity, readability, and compatibility have made it a popular choice for representing structured data. The JSON-P (JSON Processing) API provides a powerful and convenient way to parse, generate, transform, and query JSON data on the Jakarta EE Platform.  In this blog post, we will explore the fundamentals of the JSON-P API, its core functionalities, and how it empowers you to work with JSON effortlessly in your Jakarta EE applications. 

Apache Camel is an open source enterprise integration framework that helps you connect different systems and applications together with as little effort as possible. It provides a simple and powerful way to define and implement message-based routing and mediation rules. It is an implementation of the patterns described in the book Enterprise Integration Patterns by Gregor Hohpe and Bobby Woolf.

In simple terms, Apache Camel acts as a "translator" or "bridge" between different systems. It allows you to easily route, transform, and process messages as they move from one system to another. It supports a wide range of communication protocols and data formats (JSON, XML, YAML, etc.), making it easier to integrate different technologies and applications.

Do any of these situations sound familiar to you and your business? 

Need stable Payara 5. I am using latest community version.

I am using Payara 5 Community Edition and I plan to upgrade to Payara 5 Enterprise Edition.
What would be the costs?

We are using Payara Version 5.2022.5 and for some of our customers we want to move to Payara Enterprise to be up-to-date with current security patches.

We are currently using the Community edition of Payara and would like to stay with Payara 5. How much do the enterprise licenses cost to continue to do this?

I currently use Payara 5 Community and have done for many years. Payara 6 Community uses Java 11 but my product doesn't currently work with Java 11 so I would like to understand the cost of Payara 5 Enterprise. 

Our inbox is full of messages like these! Sounds familiar? It might be time to move to Payara 5 Enterprise. 

Coming at the dawn of summer, the June release of the Payara Platform is out with enhancements and bug fixes. Payara Platform Enterprise 6.3.0 comes with 2 bug fixes, 1 improvement, and 1 component upgrade. Payara Platform Community 6.2023.6 also comes with 2 bug fixes, 1 component upgrade, and 1 improvement. 

Payara 5 Enterprise will also receive a new release: Payara Platform Enterprise 5.52.0, available only to those using Payara Enterprise. If you are still with Payara 5 Community, remember it is discontinued,contact usto find out how you can still receive a supported platform.  

Oracle, together with the Java Community over the last few years, have changed the release cadence of the Platform. With biannual releases, the Java of today is a remarkable departure from Java 8. With all the rapid advancement of the language comes the problem of keeping up as a developer.

Thankfully, Java Champions Marc R. Hoffmann and Cay S. Horstmann came up with the Java Almanac website. JA is a great resource that gives you both a summary and detailed overview of changes on the Java Platform from Java 1.0 to Java 22.

The changes are organised in a tabular format with details, links to the respective API and a helpful comparison page. It also has a download page with options to download from any of the JDK distros. All in all, Java Almanac is a great resource to keep abreast of the new release cadence of the Java Platform. 

Payara, a leading provider of Jakarta EE and MicroProfile runtimes, has been authorized by the Common Vulnerabilities and Exposures (CVE) Program as a CVE Numbering Authority (CNA).

Java Records, one of the major highlights of the Java 16 release, provides a concise and immutable way to define classes for modelling data. This conciseness lends itself useful in a typical Jakarta EE application that can have a number of layers that need to share data. For example the data layer might want to return a subset of a given data set to a calling client through a data projection object. The REST layer might want to have separate entities for server and client side among others. This blog post explores the adoption of Java Records in a Jakarta EE application as a data transfer and projection object.

The Lombok project is a Java library that aims at “spicing up your java.” Started back in 2009, it consists mostly of annotations that can be used on Java classes to generate helpful constructs like getters and setters. It aims at freeing you from writing quite a number of the ceremonial boilerplate code that you sometimes need to write as part of your everyday use of Java. 

YAML is a simple, human-friendly data serialization language for all programming languages. It is the main format for working with Docker. As a language agnostic format, there are many bindings for all the major programming languages. You can easily consume and return data in the YAML format in your Jakarta REST application using message body readers and writers.

MongoDB is one of the most popular NoSQL databases in the market, with its flexible data model, scalability, and rich query capabilities. When combined with Morphia, a powerful Java library for MongoDB, Jakarta EE developers can achieve even greater flexibility in creating modern applications that deliver exceptional user experiences. Watch this webinar recording to learn how to use MongoDB with Jakarta EE and the Morphia library!

Oftentimes in a Jakarta REST application, you may need to access some metadata about a given resource method matched by the Jakarta REST runtime, outside of a resource class. This could be so as to dynamically alter the client's request based on some custom business requirement, or for informative purposes. For example, in a Jakarta REST component like an exception mapper, you might want to get the currently matched resource method and get its HTTP method. 

Are you an Enterprise Java Developer? Or even a Java developer? If yes, then here is your chance to make your voice heard in the2023 Jakarta EE Developer Surveythat is currently on-going. The survey is organized by the Jakarta EE Working Group, the body responsible for steering the development and advancement of cloud native Java development at the Eclipse Foundation.

Payara Platform Enterprise 5.50.0 also comes with 1 improvement, 1 bugfix, 1 security fix and 1 component upgrade.

As an independent online Jakarta EE instructor, I often get questions like...

Jakarta EE 10, the first major release of the platform since it was transferred to the Eclipse Foundation, did come with a slew of changes and updates to many of its constituent specifications. One such specification that received updates is the Jakarta Contexts and Dependency Injection specification. The specification release version for Jakarta EE 10 is Jakarta CDI 4.0, which came with major changes.

Two of such major changes are the split of the specification into a Lite and Full profiles and the change in default behaviour for an empty beans.xml file. In this blog post, we take a quick look at getting started with Jakarta CDI, in my view, the single most influential specification on the Jakarta EE Platform.

Welcome to our March selection of the best blogs, videos, podcasts and tutorials from the world of  Java, Jakarta EE, cloud computing and open source. 

A lot. Hot out of the Payara engineering furnace, we bring you the latest Payara Platform Community and Enterprise releases for the month of March 2023. Payara Platform Enterprise 6.0 gives you a production optimized and commercially supported runtime for your mission-critical projects, combining our top-rated support and 10 year software lifecycle with the very latest version of Jakarta EE.

Payara Platform Community 6.2023.3 is out with 4 improvements, 6 bug fixes and 3 component upgrades. Payara Platform Enterprise 5.49.0 also comes with 4 bug fixes, 3 component upgrades and 1 improvement.

What Is Payara Platform Enterprise? 

In prior versions of Jakarta EE, the use of UUID as entity ID or database primary key type was a vendor specific feature. So even though you could use it, you had to rely on vendor specific constructs to get the mapping right. With the release of Jakarta EE 10 however, the Jakarta Persistence specification now provides native support for using UUID as entity ID type.

The jakarta.persistence.GenerationType now has a UUID option that indicates to the persistence provider to generate and assign RFC 4122 UUID to the annotated field. The HelloEntity below shows how to use this new feature.

Jakarta EE 10 was released in September of 2022 as the first major release of the venerable Enterprise Java development platform since it was moved to the Eclipse Foundation. As a major release, it did come with a slew of updates to almost all the major specifications, including Jakarta REST. In this blog post, we take a look at how to get started developing RESTful web services on the Jakarta EE Platform using the Jakarta REST API.

Oftentimes in web applications, there is the need to intercept a request from the client to resource methods. Sometimes this interception must take place even before the request is matched to a resource method. For such needs, Jakarta REST provides the jakarta.ws.rs.container.ContainerRequestFilter interface. This interface is a Jakarta REST extension that can be used to intercept requests to resource methods. 

An implementation of this interface can decide if requests should be intercepted before they’re matched to resource methods through the @PreMatching annotation. A pre-matched request filter will be invoked by the container before the request is matched to its intended resource method. 

For this blog post, let us look at two use cases for request filters. One is a situation where for security reasons, certain HTTP methods are not allowed. For example an organisation can have a security rule in its firewall that disallows HTTP PUT methods. In this case, either all methods have to be POST or request filters can be used to workaround the restriction. 

The second situation is for the custom implementation of authentication. Of course you absolutely should NOT hand-roll your own security setup unless you know in detail exactly what you are doing. You are better off using tried and tested security frameworks and services out there. But for this blog post, assuming we need to implement custom security, we can use a pre matching request filter. The following code snippet below shows a ContainerRequestFilter implementation that implements the two scenarios above.

Java generics is a great feature that allows you to have compile time checks for generics. However, due to historical reasons of backward compatibility, type information for generics is erased at runtime. A lot of the time this shouldn’t be of much concern. But there are a few cases where type information is needed at runtime for some kind of decision. 

One such situation is in Jakarta REST when the jakarta.ws.rs.core.Response object is used to return a generic collection of a specific type. For example the code below shows the creation and return of a Response object that has a list of HelloEntity as the return payload to the client. 

All non-trivial enterprise applications have some sort of constraints on the data the application processes. These constraints could range from the simplest to the most complex custom built types. The default validation API on theJakarta EEPlatform, Jakarta Bean Validation has excellent out of the box support for constraining bean fields. Then with its @Valid annotation, you can trigger automatic validation of constrained objects in certain points of an application. 

We are here with a carefully curated reading list! We put together the best content from the world of Java, Jakarta EE, cloud computing and open source. 

TL:DR - if you work with enterprise Java software, you'll find something here for you.

It's a new month, and this February the Payara Fish Pond is bristling with new releases for both Payara Platform Community and Enterprise editions. Payara Platform Community 6.2023.2 is out with 3 improvements and 5 bug fixes. Payara Platform Enterprise 5.48.1 contains 2 improvements and 5 bug fixes.

The Jakarta EE Platform has come a long way since its debut as J2EE back the days of Sun Microsystems. Over the years, it has had its fair share of challenges. A natural consequence of this is that some notions about the platform arising from some of the past challenges that may have been true about past iterations have stuck. This blog post aims to dispel some of these deeply rooted misconceptions about the Jakarta EE Platform, especially after the last major release.

Wondering which cloud deployment option to use for your Jakarta EE application? 

Look no further than our latest guide, published today! 

Traditionally, enterprises stored their SQL data in relational database management systems (RDBMS). However, the strict and rigid SQL data format is not always fit for purpose...

This has led to the rise of schemaless databases and NoSQL. The distributed, non-relational model of NoSQL database technology made it the almost perfect choice for companies like Twitter, Google and Facebook that had amassed massive datasets from their web applications. 

But is it right for your enterprise? And will it work with Jakarta EE?

Jakarta EE 10 shipped with the fourth major release of its component based web framework Jakarta Faces. Hitherto known as Jakarta Server Faces, and Java Server Faces before that, Jakarta Faces, or just Faces,version 4.0is the first major version with API change since version 2.3 in Java EE 8. Among the major changes in this version are:

This post is inspired by Gunnar Morling'sposton a similar theme for the Java SE Platform. It is an opinionated guide to getting started developing applications on the Jakarta EE Platform. As an opinionated post, there may be some recommendations that you disagree with. That is natural. The post is directed at people just getting started and feel overwhelmed by all the options out there for getting started with enterprise Java. The post is broken down into the following sections;

It's January, and the Payara engineering bakery has been busy with the first release of the year. The Payara Platform Community 6.2023.1 release is hot out of the oven with 8 component upgrades, 1 improvement and 1 security fix. Payara Platform Enterprise 5.47.0 also comes with 14 component upgrades, 2 improvements, 3 bug fixes and 1 security fix. 

Jakarta EE has action and component based frameworks for building web applications using the model view controller architecture pattern. The much older Jakarta Faces is a component based framework while the much newer Jakarta MVC is an action based one. This blog starts by defining the two types, then takes a look at Jakarta MVC, what it is and how to get started.

In September 2022, the Jakarta EE community achieved a huge milestone with Jakarta EE 10 being released (read more here). The key goals of the Jakarta EE 10 release are simplicity, modernization and ensuring it is lightweight. It's been a few months since this major release, so we thought it's a good time now to do a bit of a recap. We invite you to join our series of fast-paced, no slides webinars that will bring you up to speed with Jakarta EE 10!

Using Payara Platform? You might be interested in what tools, OpenJDK versions and Jakarta EE releases our global community choose! 

We regularly conduct surveys to learn what technologies are most commonly used with Payara Platform, so we can work on our integrations and plug-ins.

This survey was promoted in October/November 2022 via social media, emails, blogs and our Payara Forum.

Batch processing is an integral part of enterprise applications. Reading, processing and storing vast amounts of data is mostly suited to batch processing runtimes that are optimized for such workloads. Inventory processing, payroll, report generation, invoice/statement generation, data migration, data conversion among others are all tasks that are suitable to batch processing.

Batch processing typically involves breaking data loads to be processed into smaller "chunks," which are also broken down into even smaller units for processing. The batch processing is then carried out on a single unit of the data, one at a time, without any human intervention. This makes the processing of a significantly large amount of data very efficient and fast. Batch processing can also be parallelized to take advantage of the hardware capabilities of the underlying computer. 

This blog series will show you how to create batch processing tasks on the Jakarta EE Platform. The blog is broken down into a series of posts, each blog covering a specific part of the batch specification. This blog introduces you to the Jakarta Batch specification and gives a high level overview of what constitutes a batch task.

The Jakarta Contexts and Dependency Injection API is the standard dependency injection framework on the Jakarta EE Platform. The latest version of the CDI specification that shipped withJakarta EE 10 is CDI 4.0. This release features a split of the core CDI API into Lite and Full. CDI Lite is designed to run in more restricted environments, and features a subset of the original features. CDI Full contains the Lite and all other features that were in core CDI in previous Jakarta EE releases.

Therelease of Jakarta EE 10marked the dawn of a new era for the platform. This release is the first major, community driven release of the platform since it was transferred to the Eclipse Foundation. As a community driven project, the platform is open for everyone to contribute to.
