An uber-JAR, also known as a fat JAR or JAR with dependencies, is a JAR file that contains not only a Java program but embeds its dependencies as well, and might also contain the web application that needs to be executed.

In this blog, we'll describe the different variants of the artifact, and the advantages and drawbacks it has.

All the best of Java, Jakarta EE, open source, DevOps and cloud from the month of June!  Tutorials, videos, podcasts, blogs and news ... carefully curated for our audience. 

The June 2022 Payara Platform release is here! This is an Enterprise-only release, with Payara Platform Enterprise 5.40.0 bringing 3 bug fixes, 1 component upgrade, and 2 improvements.

 We have also made significant improvements to our product documentation on GitHub, for both Enterprise and Community, aiming to create the best developer experience possible for those using the Payara Platform! Read more below.

The Payara Platform promises aggressive compatibility. Because we focus on providing an excellent application server, we do not seek to lock you in to a product suite or any particular tools. As you see in this blog, this is also true in the case of which implementation of the Jakarta Persistence API specification you choose to use. We explain why we run automatically with EclipseLink, but also why and how you may switch to Hibernate. 

Choose the tool that is right for your specific use case. 

We provide our selection of the best Java and Jakarta EE tutorials, videos, podcasts, blogs and news from the month of May! We also pick the best content we've found from the worlds of DevOps, cloud computing and open source. This is a carefully curated reading list, specially selected for our specific Enterprise Java niche. 

The May 2022 Payara Platform release is here! This is an Enterprise-only release, with 5.39.0 bringing 4 bug fixes, 2 component upgrades, and 5 improvements. 

JDK 17 is now supported in Enterprise! It has been tested in Community and can be relied on for mission-critical systems. Enterprise users also enjoy an improved Upgrade Tool, with more troubleshooting available when moving between Payara versions.

Every month, we collate the very best content for our specific enterprise Java - Java EE, Jakarta EE and MicroProfile - community. We also look further afield, and where it applies, include interesting blogs, videos and articles on subjects such as DevOps, cloud computing, microservices, software architecture and more. 

TL;DR: We know our audience and if we think you will find something very useful when developing enterprise Java applications - it makes the cut! 

The release of Payara 6 Community in a few weeks will be a turning point for many of our users. It's important you review all possibilities in advance. Consider migration to be supported, secure and maintain peace of mind!   

We recommend moving to Payara Enterprise,  which we consider the most cost-effective and business-savvy choice. In this blog we explain 5 different scenarios.

Google Remote Procedure Call, or gRPC, is an open source Remote Procedure Call (RPC) framework focused on high performance and portable to any environment. It is an alternative to REST, deemed by many as more efficient.

After one of our customers requested it, the extension became available in our April 2022 Payara Community and Enterprise releases: 5.2022.2 and 5.38.0. 

The April 2022 Payara Platform release is here! Payara Platform Community 5.2022.2 brings 13 bug fixes, 2 component upgrades, 3 improvements and 3 security fixes, whilst Payara Platform Enterprise 5.38.0 includes 2 bug fixes, 1 improvement and 4 security fixes. 

It includes the fix for "Spring4Shell", and improved support for Jakarta EE 9, as you can now run Jakarta EE 9 applications using PrimeFaces.

This release also gives Payara users the ability to use gRPC, the Google Remote Procedure Call Framework.

Please note: This is the penultimate Payara 5 Community release. Payara 6 Community will soon take its place, to be used with Jakarta EE 10. If you want to keep using earlier Java EE/Jakarta EE versions - we encourage you to move to Payara 5 Enterprise.
