JBoss AS 7.0.1 and EJB 3 lookup

paykin Aug 25, 2011 2:54 AM

Hello,

I deploy my app as 2 separate deployments: EAR and WAR.

I put my EJB interfaces inside both WAR and JAR inside EAR.

When I trying to lookup EJB from WAR I recieve exception:

java.lang.ClassCastException: ruleEngine.api.ApplicationData$$$view12 cannot be cast to org.omg.CORBA.Object

at org.jboss.com.sun.corba.se.impl.javax.rmi.PortableRemoteObject.narrow(PortableRemoteObject.java:225) [jboss-rmi-api_1.0_spec-1.0.1.Final.jar:1.0.1.Final]

or simple ClassCastException when I just cast the class without narrowing.

The application worked fine in JBoss 6, only when I put property

properties.put(Context.PROVIDER_URL, "jnp://localhost:1099");

to InitialContext. When I removed the property, I started to recieve the same error as on JB7.

Unfortunatelly, I can not create separate jar with interfaces, because of dependencies exist in the project. Because of the same problem I can not include EAR JAR in WAR's classpath.

Any help?

Is it a remote business view or a local business view?

If it is a local, it is not supposed to work.

If it is a remote, it is a bug in both AS 6 and 7.

It is Remote interfaces.
Can I somehow make it work?
Thanks

Can you post a stack trace?

We can patch the AS code. :-)

paykin Aug 26, 2011 3:49 AM (in response to wolfc)

I attach full stacktrace.

As I see the problem,

The classloader of ApplicationData.class is:
ModuleClassLoader for Module "deployment.RuleEngineEjb.ear.RuleEngine.war:main" from Service Module Loader

The clasloader of remote interface ("obj") is:
ModuleClassLoader for Module "deployment.RuleEngineEjb.ear.RuleEngine.jar:main" from Service Module Loader

i.e. the classloaders are diferent, so it can not make direct casting.

The following is a snippet of a code that produces the error.
I tried to pack WAR inside the EAR, it produces the same error.

...
Object obj = context.lookup(jndiName);
...
// EJBHomeFactory.java line 66
Object homeInterface = javax.rmi.PortableRemoteObject.narrow(obj, ApplicationData.class);
...

Ah yes, silly me. That trace won't give any help. My bad.

The problem lies in org.jboss.as.ee.component.ViewService$View$ViewInstance.createProxy. In case of a remote view it should create a proxy using the TCCL.

Either pull in the request in your own development branch or wait for AS7-1939 to finish.

Hi

I'm able to lookup with latest AS 7.0.x build version SLEJB using @EJB Annotation from WEB Container.
My question is, how can I lookup clustered SLEJB...?
In AS 6 there is Annotation import org.jboss.ejb3.annotation.Clustered ( @Clustered ) which will do the job for HA-JNDI.
I can't find this Annotation in any of AS 7.0.x jars...

Any suggestions?
