Weld SiteCommunity Documentation
Weld, the CDI Reference Implementation (RI), can be downloaded from the download page. Information about the Weld source code repository and instructions about how to obtain and build the source can be found on the same page.
Weld provides a complete SPI allowing Java EE containers such as WildFly, GlassFish and WebLogic to use Weld as their built-in CDI implementation. Weld also runs in servlet engines like Tomcat and Jetty, or even in a plain Java SE environment.
Weld comes with an extensive library of examples, which are a great starting point from which to learn CDI. In addition, a number of quickstarts featuring CDI can be found at the JBoss Developer site
