Description
There is a problem during the lookup between two ejb when I configure Isolation classloding for the ears
I have configured all ears to be in isolated classloader spaces and using call by value for remote interface.
the configuration file deploy/ear-deployer.xml contains :
Code:
<mbean code="org.jboss.deployment.EARDeployer"
name="jboss.j2ee:service=EARDeployer">
<!-- A flag indicating if ear deployments should have their own scoped
class loader to isolate their classes from other deployments.
-->
<attribute name="Isolated">true</attribute>
<!-- A flag indicating if the ear components should have in VM call
optimization disabled.
-->
<attribute name="CallByValue">true</attribute>
</mbean>
I have deployed one ear that contains two ejbs : ejbA and ejbB;
the ejbA calls the ejbB in the same way :
Code:
Context initCtx = new InitialContext();
Context ejbCtx = (Context)initCtx.lookup("java:comp/env/ejb");
Object objRef = ejbCtx.lookup("MyStatless");
System.out.println("++++ objRef Classloader = "+objRef.getClass().getClassLoader().toString());
System.out.println("++++ MyStatlessHome Classloader = "+MyStatlessHome.class.getClassLoader().toString());
home = (MyStatlessHome)PortableRemoteObject.narrow(objRef, MyStatlessHome.class);
MyStatless clientStatless = (MyStatless)home.create();
and I have configured ejb-ref in ejb.jar.xml :
Code:
<ejb-ref >
<ejb-ref-name>ejb/MyStatless</ejb-ref-name>
<ejb-ref-type>Session</ejb-ref-type>
<home>it.csi.oss.clusterejb.interfaces.MyStatlessHome</home>
<remote>it.csi.oss.clusterejb.interfaces.MyStatless</remote>
</ejb-ref>
and in jboss.xml :
Code:
<ejb-ref>
<ejb-ref-name>ejb/MyStatless</ejb-ref-name>
<jndi-name>jnp://cst001.csi.it:1100/ejb/MyStatlessClient</jndi-name>
</ejb-ref>
unfortunately I obtain following exception :
2006-06-06 13:57:01,223 INFO [STDOUT] ++++ objRef Classloader = org.jboss.util.loading.DelegatingClassLoader@114e777

as you can see the two classloder are different :
