[jboss-jira] [JBoss JIRA] Commented: (EJBTHREE-983) @EJB injection fails, RuntimeException, IllegalArgumentException

[William DeCoste (JIRA)]

William DeCoste commented on EJBTHREE-983:
------------------------------------------

Are the two deployments using the same classloader or have you configured a scoped classloading repository? Looks like the problem might be that the proxy being injected was instantiated using a different classloader than the classloader doing the injecting. If this is the case, you can workaround this issue by setting the CallByValue attribute of the jboss:service=Naming service to true (configured in conf/jboss-service.xml).

> Similar to bug EJBTHREE-862.  However, setting `Isolated' to false in $JBOSS_HOME/server/XXX/deploy/ear-deployer.xml does not resolve the issue for me.
> Here is the scenario:
> There are two applications, app1.ear and app2.ear.
> app1.ear contains a stateless session bean, App1Bean, with local and remote interface
> app2.ear contains a stateless session bean, App2Bean, which has a field defined like so:
> @EJB(mappedName="app1/App1Bean/local")  // I've tried local and remote
> com.app1.ejb.session.App1 app1;
> app1.ear and app2.ear are loaded successfully by the application server.
> When App2Bean is activated, JBoss tries to perform the injections.  At this point, the RuntimeException (see stack below) occurs.
> App2Bean can successfully obtain a reference to app1 bean using the traditional JNDI lookup methods.  This is a workaround.
> When inspecting the stack, notice the presence of IllegalArgumentException, even though the interface matches.
