The 2.0 version does not mark the start of using CDI in SE, as that support was already provided in a non-standard way. Both Apache OpenWebBeans and Weld did support the SE mode, and these have been standardized now for use with CDI in Java SE. There are also other projects that support CDI such as Apache DeltaSpike, which offers portable extensions that are handy features for Java developers.
To get started, you can create a Maven project and declare a dependency on a CDI implementation such as JBoss Weld. If Maven isn’t your cup of tea, you can use other means to get the weld-se-core library added to your standalone SE project. Your pom.xml should have a dependency declaration, as shown here:
<dependency> <groupId>org.jboss.weld.se</groupId> ...
