Occasionally, users have the need to override the version of JSF included in the application server by bundling a different version of JSF with their application. If you are trying to use CDI in such a scenario, you might have noticed it does not work. Is there a way out?
Yes, there is, by including a small JAR and some configuration in your web application you can make this scenario work.
Add the following Maven dependency to your web application.
<dependency> <groupId>com.oracle.cdi-enabler</groupId> <artifactId>cdi-enabler-1_0</artifactId> <version>1</version> <scope>compile</scope> </dependency>
Then add the following beans.xml to your WEB-INF directory and you are set to go!
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/beans_1_0.xsd"> <alternatives> <class>com.oracle.cdi_enabler.CdiConversation</class> </alternatives> </beans>
Note this particular version of the JAR requires you to use this on a JavaEE6 container that bundles a CDI 1.0 implementation, like Glassfish 22.214.171.124 or Weblogic 12.1.2.
