GlassFish 8.0.2 Released: With important security fixes, other improvements, and commercial support

Tue, 19 May 2026 13:32:00 +0000

The latest version of Eclipse GlassFish 8.0.2 was released on May 5, 2026, with fixes for several critical vulnerabilities. It builds on top of a lot of subtle work and improvements in GlassFish components like the Eclipse Grizzly HTTP framework, or in related components like Eclipse OpenMQ message broker and Eclipse ORB (CORBA) for remote EJB calls. The release of GlassFish 8.0.2 serves as further evidence that GlassFish remains an actively evolving platform, backed by the dedicated maintenance and commercial support of the OmniFish team. As I was deeply involved in this release, I’d like to share a deeper look into the technical advancements within this new version.

Eclipse GlassFish: This Isn’t Your Father’s GlassFish

Tue, 24 Mar 2026 15:30:49 +0000

GlassFish is an application server with a long history and has always had a special role in the Java world as the reference implementation of Java EE, being one of the most popular Java EE servers. Since Oracle lost interest in the project several years ago, developers and organizations have held certain beliefs about GlassFish, often based on their experiences with older versions.

If you still think of GlassFish as a slow, unsupported, and purely for-development application server, it’s time to take a fresh look. At OmniFish, we’ve been working hard to change that perception since 2022. The Eclipse GlassFish of today, particularly from version 7.0 onwards, is a completely different platform, and we’re proud to show you what we’ve helped to build with the rest of the Eclipse GlassFish contributors.

Performance Best Practise No. 1: Optimize Database Operations

Wed, 11 Jun 2025 13:24:32 +0000

Database operations are a very critical part of most applications in regards of performance. There are multiple reasons why database operations can significantly contribute to lower performance:

The database often runs on a remote server, slowing down communication with the database and the data transfer
Establishing individual connections to a database can take a significant portion of time compared to running the whole database query
Database queries can run for a long time
Network communication is unstable and may required restarting queries in case of network failures

You can address the above issues and boost Jakarta EE database performance by leveraging the following best practices.

EJB support in Piranha via CDI

Tue, 15 Nov 2022 14:14:42 +0000

Enterprise Beans was once the face of Java EE, but as we discussed in the previous article , is currently de-emphasised in Jakarta EE.

However, since there’s so much existing code using Enterprise Beans, a certain level of support is still desired.

Piranha Cloud , a relatively new runtime supporting Jakarta EE, takes a somewhat novel approach to Enterprise Beans. Instead of implementing a separate container, Piranha Cloud, via the OmniBeans project, maps Enterprise Beans annotations to equivalent functionality in CDI itself, or to technologies in Jakarta EE leveraging CDI (such as Jakarta Transactions).

The Future of EJB

Thu, 10 Nov 2022 16:06:56 +0000

EJB, or Enterprise Beans, are Java classes with a number of container provided services attached to them, such as transactions, remoting and security. In this article we will take a look at what we can expect for EJB in the future.

Once upon a time EJB was almost synonymous with what was called Java EE or J2EE back then (Jakarta EE now). It suffered from many issues though, although it did incrementally got better. We’ll explore some of those issues next.
