ClassNotFound / ClassCast when trying to use JCA Connector deployed in rar in JBoss EAP 6

Issue

• We have been using a JCA Resource Adapter (the example.rar). The adapter can be configured correctly in JBoss 6.0 EAP (if we disable JCA validation). A Lookup JNDI returns the ConnectionFactory. With the ConnectionFactory I can get a Connection, and with the Connection I can get an Interaction. The problem lies when trying to initialise an ExampleSpec which is the object used as a parameter in the execute() method. I get the following ClassNotFoundException:

 java.lang.ClassNotFoundException: com.jboss.examples.resource.adapter.ExampleSpec

• This Class is in a JAR, in the RAR, at the same level as the other Classes used. I auto deployed the RAR by putting it in the deployments directory, but the problem persists even if I deploy it manually or try declaring the JARs as a module and adding dependencies.

• We are getting a class cast exception when our war application tries to access our resource adapter that is deployed in a rar

java.lang.ClassCastException: com.jboss.examples.resource.adapater.HelloWorldInteractionSpecImpl cannot be cast to com.jboss.examples.resource.adapater.HelloWorldInteractionSpecImpl
