In this last blog of the Getting Started with Jakarta EE 9 blog and video series, we have a look at the Bean Validation specification. Using this specification, you can define some validation rules, from some simple ones on a single field to very complex ones on a business entity, that are reusable depending on the input frameworks you are using within your application.

We’re pleased to announce that our October 2021 Payara Platform Survey results are now available! 

This survey was promoted to our audience in October 2021. We shared with Payara Platform Enterprise customers and Community users via social media, emails and blogs. Thank you so much to everyone who took the time to contribute!

Ever wondered about all the names involved with running Java web applications? Web Server, Application Server, Application Runtime and so on? 

In this guide, we dive a bit deeper in to the terms to help elimate some of the confusion! 

Adam Bien explored the possibilities of Payara Cloud in his recent talk for the 2021 J4K conference! 

He used the Payara Cloud demonstration environment - with the caveat that the user interface is not completed yet - to demonstrate how our next generation application server creates a "serverless" environment; moving the "plumbing behind the scenes" so you only have to worry about selecting your WAR, clicking deploy, and running it on the cloud! 

JDK 17, the next Long-Term Release of Java SE, launched in September. You may have seen many of the great blogs, articles, and videos about what this means for Java developers. For just a few places to start, we like: theJetBrainsteam'sdiscussion on migrating to JDK 17; Todd Ginsberg onhis ten favourite features; andGunter Rotsaert mapping out thedifferences between Java 11 and Java 17. 

But what does the new release mean forJakarta EEdevelopers specifically? If you are using these enterprise-orientated specifications, stewarded by theEclipse Foundation, should you make the switch?

Payara's Rudy De Busscherthinks you should, and explained why in his talk toIstanbul JUG, powered byHazelcast.

In October, ourJavaandJakarta EEcommunity has still been digesting the new long-term support release, JDK 17, out last month. Below, find useful articles such as theJava Champions demystifying the new licensing,Per Liden on the inclusion of Z Garbage Collection, andGunter Rotsaert on differences between Java 11 and Java 17- some of our favourite experts are helping the community get to grips with improvements and changes!  

The innovative Payara team are always looking forward though, and work is in full swing for Jakarta EE 10. Particularly popular this month was a blog by our CEO Steve Millidge, who is project lead for the Jakarta Concurrency project, a specification within theEclipse FoundationJakarta EE that works on transferability between Java SE Concurrency and its enterprise-orientated counterpart. Make sure you check it out if you are interested in honing your open source skillls by contributing to a project (Steve is actively looking for volunteers to test, write documentation and develop) but also if you want to know more about what you can do with Jakarta Concurrency in its current form.

Big news also is the new and improvedPayara Forum. We've moved from Google Groups to a new location that makes it easier to discuss use of Payara Platform with like-minded developers - and our engineers! Make sure you have investigated it. 

In addition to JDK 17 tips and tricks, and Jakarta Concurrency content, please find below our pick of the best blogs, articles, videos and podcasts from the world of Java, Jakarta EE, MicroProfile, open source and DevOps over the last month. We also include industry news and where you can find Payarans across the web!

Jakarta EE, previously Java EE, is a set of specifications that enables the world wide community of Java developers to work on cloud native Java enterprise applications. It is an open source project maintained by theEclipse Foundation.

Jakarta Concurrency is a small, but fundamental, specification under the Jakarta EE umbrella. As project lead, I provide more information on what it is, its future and how to be involved.

Iberian & South American Payara Platform users: we have recently participated in both theJakartaOne - PortugeseandJakartaOne - Spanishvirtual conferences!

You can now catch up on the videos: vendor talks, discussing what we do at Payara Services, benefits of our products, and more about our customers; and at Jakarta One - Spanish, an informative microservices security talk, using identity platformOkta. 

A key goal of Jakarta Concurrency is creating a simple path betweenJava SEandJakarta EE (previously Java EE) - making it easy for organisations scaling up to migrate their mission-critical applications to the enterprise-orientated Jakarta EE specifications.

Steve Millidgeexplained more in hisEclipse FoundationJakarta EE Tech Talk. You can now watch the video! 

Payara Server has a strong relationship withMicrosoft Azureand theJava at Microsoft team - and now, there's an official best practice Azure Sample for running Payara MicroonAzure Kubernetes Service(AKS)! 

This is a reaction to more and more Azure customers wanting to run Payara on Azure, with many moving from GlassFishto Payara Micro on AKS. It also precedes the next step for Azure and Payara:  releasingPayara Cloud as a PaaS running on Azure.
