Weld is the reference implementation of CDI: Contexts and Dependency Injection for the Java EE Platform - a JCP standard for dependency injection and contextual lifecycle management and one of the most important and popular parts of the Java EE. Weld is integrated into many Java EE application servers such as WildFly, JBoss Enterprise Application Platform, GlassFish, Oracle WebLogic Server, WebSphere Application Server and others. Weld can also be used in plain servlet containers (Tomcat, Jetty) or Java SE.
To use Weld today, download the
(formerly JBoss AS) and add the following code to the
file of your application:
<dependency> <groupId>javax.enterprise</groupId> <artifactId>cdi-api</artifactId> <!-- Use version 2.0 for Weld 3 --> <version>1.2</version> <scope>provided</scope> </dependency>
Each version of WildFly is shipped with given version of Weld. However, WildFly and Weld have different release cadences. Therefore, with every Weld release we also create a patch which allows you to easily upgrade:
|WildFly||Ships with Weld||Available Patches|
|WildFly 11.0.0.CR1||Weld 2.4.3.Final CDI 1.2||
|WildFly 11.0.0.Beta1||Weld 2.4.3.Final CDI 1.2||
|WildFly 10.1.0.Final||Weld 2.3.5.Final CDI 1.2|
|If you’re not familiar with patching WildFly, check the FAQ.|
