[jboss-jira] [JBoss JIRA] Closed: (EJBTHREE-862) EJB 3.0 dependencies injection accross EARs

[Alexey Loubyansky (JIRA)]

     [ http://jira.jboss.com/jira/browse/EJBTHREE-862?page=all ]

Alexey Loubyansky closed EJBTHREE-862.
--------------------------------------

    Resolution: Rejected

In my opinion, this is an application and/or server configuration issue but not a bug.
Check out http://wiki.jboss.org/wiki/ClassLoadingConfiguration. Specifically  "Accessing EJBs in isolated ears".
You have to serialize JNDI access. Either set CallByValue for NamingService to true (in conf/jboss-service.xml) or specify the full lookup scheme in jboss.xml (see the wiki page) or with annotations:

public class FirstBean implements First
{
   @EJB(mappedName="jnp://localhost:1099/externalrefscoped/Second")
   private Second second;

I've modified the testcase in ejb3/core to demonstrate this.

> Note that this issue occurs only if the EARDeployer's attribute Isolated in ear-deployer.xml is set to true.
> We have a deployment schema similar to the example from EJB 3.0 specification (chapter 19.6 Example):
> ear1:
>        FirstReferencer.jar Class-Path:FirstReferencer-client.jar SecondReferencer-client.jar
>        FirstReferencer-client.jar
>        SecondReferencer-client.jar
> ear2:
>       SecondReferencer.jar Class-Path:SecondReferencer-client.jar
>       SecondReferencer-client.jar
>                   deployment descriptor contains:
>                   <ejb-client-jar>SecondReferencer-client.jar</ejb-client-jar>
> There are two session beans  FirstReferencer and SecondReferencer. FirstReferencer references SecondReferencer over the dependency injection. After deployment if we call the business method on the FirstReferencer, which in turn calls SecondReferencer we get exception like this:

> On debuging and from the stacktrace of the exception we can see that the lookup for refernced EJB works fine but the assigning over reflaction fails. It seems to be a ClassLoading issue there.
