Hide Passwords with Password Aliases in Payara Server


When performing the configuration of the Payara Server for your application, you often need to supply a password. The password to connect to the database is a classic example, but there are many situations where you need to enter this kind of sensitive data.

With Payara Server, you have the option to hide this kind of sensitive data from the user, so that this information is much better secured.

How to Improve Domain Data Grid Performance (Japanese Language)

現在のPayara Platformアーキテクチャの基礎となるのは、ドメイン・データ・グリッドの採用です。ドメイン・データ・グリッドは複数のPayara ServerまたはPayara Microインスタンスを結合して、互いにデータを共有する交換可能なノードの堅牢なクラスタを形成し、クラスタにデプロイされたあらゆるアプリケーションに対して高可用性とフェールオーバー機能を提供します。

How to Improve Domain Data Grid Performance

One of the cornerstones of any modern Payara Platform architecture is the use of the Domain Data Grid. The Domain Data Grid allows multiple Payara Server or Payara Micro instances to join and form a robust cluster of interchangeable nodes that can share data between each other and grant High Availability and Failover capabilities to any applications deployed in the cluster. 

Payara Services Joins MicroProfile Working Group

Payara is pleased to announce that we have joined the MicroProfile Working Group. This builds on our commitment to shaping and improving Enterprise Java for both microservices and monolithic architectures. 

The MicroProfile project was born as a community initiative to optimise Enterprise Java with a microservices standard platform. It joined theEclipse Foundation in 2017, an independent open source software association, with the goal of driving innovation with a vendor-neutral "incubation" environment.

The Eclipse Foundation's MicroProfile Working Group encourages collaboration between participants, working in short cycles to propose and gain approval for new common APIs and functionality - and in turn drawing on the knowledge of a wide variety of different vendors. As one of the contributors, Payara engineers will shape and drive the future of the MicroProfile specifications.

We talked to our Founder and CEO Steve Millidge to find out more about what this means. 

Creating a Kubernetes Operator in Java

Kubernetes is much more than a runtime platform for Docker containers. Through its API you can not only create custom clients, but you can also extend Kubernetes. Those custom Controllers are called Operators and work with application-specific custom resource definitions.

How to Use Eclipse Transformer to Convert a 3rd Party Library to the New Jakarta Namespace (Japanese Language)


Jakarta EE 9のリリースは、Java Enterpriseの伝統を破るものとなります。OracleからEclipse FoundationへのJava EEコード寄贈の法的な要件は、javax名前空間をjakarta名前空間に変更することです。

しかし、Jakarta EE 9でのパッケージとXMLの名前空間の変更はまだ始まりに過ぎません。名前空間の変更により、新たな開発や機能追加が可能となりましたが、Java Enterprise仕様の一部を使用しているフレームワークやライブラリもすべて新バージョンに合わせて調整する必要があります。

How to Use Eclipse Transformer to Convert a 3rd Party Library to the New Jakarta Namespace


The release of Jakarta EE 9 breaks a tradition of Java Enterprise. A legal requirement of the Java EE code donation from Oracle to the Eclipse Foundation is the change of the namespace of javax to jakarta.

But the change of the package and XML namespace in Jakarta EE 9 is only the beginning. The change of the namespace allows for new development and functionality, but all frameworks and libraries using one of the Java Enterprise specifications also need to be adjusted to the new version.

The Payara Monthly Catch: December 2020

In December, the biggest news was Jakarta EE 9’s official release, completing the move to the jakarta namespace. This officially took place at the Eclipse Foundation Jakarta One Livestream, where our CEO Steve Millidge took part in the keynote speech (watch here) and presented as lead on the GlassFish project (video here). 

In other major release news, MicroProfile 4.0 was made available towards the end of the month, with the delayed release set to bring in new features including alignment with Jakarta EE 8. 

Payara has also enjoyed kick-starting healthy debate this month, with our CEO Steve Millidge proposing that Ahead of Time Compilation with GraalVM isn’t always all it’s cracked up to - and watching the comments roll in!  

We are hoping to continue to make bold statements and drive forward discussion in the Java and Jakarta EE community in 2021.
