Securing Payara Server and Payara Micro with a Supported JDK

As you probably already know, Oracle decided to stop providing public updates for Oracle Java Development Kit 8 (JDK 8) in January 2019. Public updates and security fixes will be provided by Oracle only for the latest version of Oracle JDK, for 6 months until the next new version. While personal users will still continue to get updates for Oracle JDK 8 until December 2020, commercial companies that plan to use it after January 2019 will either need to become Oracle customers or switch to a JDK 8 distribution supported by someone else to receive regular updates with critical and security fixes.

 

10th Anniversary of Java2Days - Payara Services Had to Be There!

I've been to Sofia, Bulgaria, a couple of times already. It all started with the Java2Days organizers inviting the Payara team to give a talk 2 years ago. But this time it was something special. The organizers joined forces with other IT conferences and prepared a special edition for its 10th anniversary in what is probably the largest building in Bulgaria - the National Palace of Culture.

 

Be Reactive and Micro with a MicroProfile Stack at Code One & Devoxx BE

Our goal within the Payara project is to facilitate innovations in Java web and enterprise applications. There are many areas to innovate but one of my favourite is better and simpler support for reactive programming. I've been exploring this area for a while. I have found some clever ways how to use standard APIs and Payara Platform to write reactive applications. This year in one of my session at Oracle Code One and Devoxx Belgium, I will focus on using MicroProfile API to write reactive microservices with simple code.

 

From Monoliths to Pragmatic Microservices with Java EE

It seems like Microservices architecture is almost everywhere these days. For a long time, I used to have a feeling that many people talked about it but very few use it. So I decided to find out how to get the most out of Microservices. I've studied this architecture a lot, experimented with the technology created specifically for Microservices and talked to other people who knew more than me. This how I've met some incredible people. And it's also a reason why I've joined forces with Reza Rahman and Ivar Grimstad to create a Hands-on Lab about our findings, which we'll present at Oracle Code One this year.

カスタムSSL証明書を用いたPayara Serverのセキュア構成

Payara Serverの管理タスクで最も多いものの1つは、他のWebサーバーと同様に、HTTPプロトコルやPayara Serverへのリモート・アクセスをセキュアにするための電子証明書のセットアップです。自己署名証明書または信頼できる認証機関の署名入り証明書のいずれかをお持ちでしょうが、どちらの場合も証明書をPayara Serverのドメインに追加してセキュアな通信に用いるのはとても簡単です。

 

How to Write Reactive Applications with MicroProfile

Eclipse MicroProfile is a framework that brings innovative technology to enterprise applications. Both Payara Server and Payara Micro provide the most recent MicroProfile version as soon as possible. Along with the aim to simplify development of microservices and cloud deployment, MicroProfile is continually adopting other modern approaches and patterns like reactive programming.

 

A Step-by-Step Guide from Traditional Java EE to Reactive Microservice Design

A workshop given at JPrime conference in May 2018.

Have you wondered how you can improve the design of your applications to improve its performance? You probably heard that reactive design can help achieve better response time and make your applications more flexible. But you’re asking: Do I need to rewrite my applications from scratch? Do I need to learn a new framework for all that? The answer is no, especially if your application is built on top of Java EE and Java 8.
