In Relation To

Seam's new project lead, Shane Bryzak, announced last week on the seam-dev mailinglist that the Weld Extensions project has be brought under the Seam project banner and renamed to Seam Solder. Today we are announcing the first release of Seam Solder, 3.0.0.Beta1!

We've decided to make a few changes to the leadership of the Seam and Weld projects, the reasons for which I'll outline in this blog post. First however, let me give you the headline changes!

I've just published a release candidate for Weld 1.1.0, the reference implementation of JSR-299: Contexts and Dependency Injection for Java EE. It's based on the CDI 1.0 API. You can find direct download links at the bottom of this post or you can pull the artifacts from the JBoss Maven Repository.

There were a number of comments on twitter and blogs last week discussing Weld's performance and scalability, and I wanted to comment on the issues discussed and our work to resolve them. Upfront, let me say that we have been actively working on performance and scalability for a while now (previously more on memory usage, more recently on performance). Of course, we work primarily with JBoss AS, but also work closely with the GlassFish team; many of the improvements will be directly available as Weld is updated in GlassFish, and we'll continue to support the GlassFish team in any performance work they do on GlassFish that impacts on Weld.

Weld Extensions is a portable library (licensed under the ASL 2) providing utilities and common functionality for CDI applications and libraries or frameworks based on CDI alike. We'll be using it as the base of Seam 3. It contains extensions to the core CDI programming model, typed logging (courtesy of JBoss Logging 3), managed resource loading and support for evaluating EL anywhere.

I'm very pleased to say that we have released the first beta of Weld 1.1.0, the reference implementation of JSR-299: Contexts and Dependency Injection for Java EE. It's based on the CDI 1.0 API. You can find direct download links at the bottom of this post or you can pull the artifacts from the JBoss Maven Repository.

The goal of this blog post is to walk you through an Java EE 6 application from a simple, static web page until we have a full blown stack that consist of the stuff in the list below. I'm calling this stack Summer because after a long, hard winter Spring may be nice but boy, wait until Summer kicks in ;-)

We've been starting to think about what we want to include in Weld 1.1. Of course, you can expect the usual bug fixes, as well as a few new features -- I'll outline those for you here.

I'm often asked to identify what projects I'm working on at Red Hat, or what group I'm a part of. My response reads like a laundry list:

Weld Extensions is set of portable services and utility classes for CDI which make up a good base layer for extension and application development. You can read more about the sort of portable extensions we are planning in this interview I gave.
