Hi ,

I have an EAR which I deploy in jboss-5.1.0.

A.EAR
    |----lib/x.jar
    |----EJB1.jar
    |----EJB2.jar

 I wanted to just expose the interfaces from the EJB's, hence I have jboss-classloading.xml in both EJB1.jar and EJB2.jar.
What I was hoping to achieve is that just have the interfaces exposed in my EJB's to other EJB's in the same EAR and also to other EAR's in AS.

EJB1.jar
    |-----------com.ejb1.interface.EJB1Intf / EJB1IntfLocal extends EJB1Intf / EJB1IntfRemote extends EJB1Intf
    |-----------com.ejb1.implementation.EJB1Bean implements EJB1IntfLocal,EJB1IntfRemote.
    |-----------META-INF/jboss-classloading.xml

<classloading xmlns="urn:jboss:classloading:1.0" domain="A.EAR-0.0.1-SNAPSHOT-exploded.ear" parent-domain="DefaultDomain"
    export-all="NON_EMPTY" import-all="true" excluded="META-INF">
    <capabilities>
        <package name="com.ejb1.interface" />
    </capabilities>
</classloading>

Similarly for EJB2.jar.

This is how my jmx-console looks like:
h2. jboss.classloader
*  http://localhost:8080/jmx-console/HtmlAdaptor?action=inspectMBean&name=jboss.classloader%3Asystem%3D557851707%2Cdomain%3D%22ExamplesEAR-0.0.1-SNAPSHOT-exploded.ear%22 domain="A.EAR-0.0.1-SNAPSHOT-exploded.ear",system=557851707

*  http://localhost:8080/jmx-console/HtmlAdaptor?action=inspectMBean&name=jboss.classloader%3Aid%3D%22vfszip%3A%2FVolumes%2FMustang%2Fbranch%2FJBoss_CELMI_20091103%2Fjboss-5.1.0.GA%2Fserver%2Fcelmi%2Fdeploy%2FExamplesEAR-0.0.1-SNAPSHOT-exploded.ear%2FProducerEJB-0.0.1-SNAPSHOT.jar%2F%22 id="vfszip:/jboss-5.1.0.GA/server/default/deploy/AEAR-0.0.1-SNAPSHOT-exploded.ear/EJB1.jar/"

EJB1 calls EJB2 via JNDI.

EJB1Bean:
public boolean callTheOtheEJB() {
    EJB2Intf myStateless = lookup(EJB2Intf.class, "service/EJB2IntfBean");
    logger.info("Called myStateless sayHello = "+  myStateless.sayHello());
     return true;
    }


EJB2Bean:
public String sayHello(){
     return "Hello"
}


My Client:
Properties props = new Properties();
    props.put(InitialContext.INITIAL_CONTEXT_FACTORY, "org.jnp.interfaces.NamingContextFactory");
    props.put(InitialContext.PROVIDER_URL, "jnp://127.0.0.1:1099");
    try {
        InitialContext jndiContext = new InitialContext(props);
        Object obj = jndiContext.lookup("AEAR-0.0.1-SNAPSHOT-exploded/EJB1Bean/remote");
        System.out.println(obj.getClass());
        EJB1Intf callingEJBIntf = (EJB1Intf)obj;
        callingEJBIntf.callTheOtheEJB();
 
    } catch (NamingException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }


Problem: EJB1 cant see EJB2Intf.

Caused by: java.lang.ClassNotFoundException: com.ejb2.interface.EJB2Intf from BaseClassLoader at 1f9c621d{VFSClassLoaderPolicy at 53ed6e21{name=vfszip:/jboss-5.1.0.GA/server/default/deploy/AEAR-0.0.1-SNAPSHOT-exploded.ear/EJB1.jar/ domain=ClassLoaderDomain at b901239{name=AEAR-0.0.1-SNAPSHOT-exploded.ear parentPolicy=BEFORE parent=ClassLoaderDomain at 7a0aae8a{DefaultDomain}} roots=[DelegatingHandler at 148464531[path=AEAR-0.0.1-SNAPSHOT-exploded.ear/EJB1.jar context=file:/jboss-5.1.0.GA/server/default/deploy/ real=file:/jboss-5.1.0.GA/server/default/deploy/AEAR-0.0.1-SNAPSHOT-exploded.ear/EJB1.jar]]  delegates=null exported=[com.ejb1.interface]NON_EMPTY}}

They are part of the same ClassLoaderDomain.

When I do listExportingClassloader() for AEAR domain,
{com.ejb1.interface=[jboss.classloader:id="vfszip:/jboss-5.1.0.GA/server/default/deploy/
AEAR-0.0.1-SNAPSHOT-exploded.ear/EJB1-SNAPSHOT.jar/"], 
com.ejb2.interface=[jboss.classloader:id="vfszip:/jboss-5.1.0.GA/server/default/deploy/
AEAR-0.0.1-SNAPSHOT-exploded.ear/EJB2-SNAPSHOT.jar/"]}



Can anyone help? I am not sure where I am going wrong.
