GlassFish Embedded – a simple way to run Jakarta EE apps

I’ve been asked by the Eclipse GlassFish project to say a few words about how I use GlassFish Embedded. And since they are working on a series of complex issues that I have raised I guess that is fair. The OmniFish team is one of the main contributors to the GlassFish project and I allowed them to post my article on their blog too.

EJB support in Piranha via CDI

Enterprise Beans was once the face of Java EE, but as we discussed a while ago, 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). Enterprise Beans features not currently present in Jakarta EE, such as the pooled concept for Stateless beans, are provided by the OmniServices library.

The future of EJB

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.
