Class Cast Exception

[seshu Palamanti]

I am using WSAD 5.1.1 for testing my CMP entity bean from Universal Test Client.I use JNDI look up to get a ref of my local home interface i got it like this.

Object o = context.lookup("ejb/Sqa_audit_reviewLocalHome");
auditrhome = (Sqa_audit_reviewLocalHome)o;

at line 2. i get this Exception

java.lang.ClassCastException: com.sbc.eworks.sqa.ejb.entity._EJSRemoteCMPSqa_audit_reviewHome_96846b2b_Stub
at com.sbc.eworks.ejb.session.SQAServiceEngineBean.searchByReviewId(SQAServiceEngineBean.java:169)
at com.sbc.eworks.ejb.session.EJSLocalStatelessSQAServiceEngine_d93b245b.searchByReviewId(EJSLocalStatelessSQAServiceEngine_d93b245b.java:87)

MY SERVER CONSOLE HAS THIS TO SAY

ExceptionUtil E CNTR0020E: Non-application exception occurred while processing method "searchByReviewId" on bean "BeanId(SQADatabaseEAR#SQAEJB.jar#SQAServiceEngine, null)". Exception data: java.lang.ClassCastException: com.sbc.eworks.sqa.ejb.entity._EJSRemoteCMPSqa_audit_reviewHome_96846b2b_Stub

Seshu,
Pardon me for stating the obvious, but the "Object" returned by your lookup method is _not_ an instance of "Sqa_audit_reviewLocalHome". Have you tried printing out the actual type, like this:

System.out.println(o.getClass().getName());

By the way, the usual way to do the cast is to use the "narrow()" method in class PortableRemoteObject:

auditrhome = PortableRemoteObject.narrow(o, Sqa_audit_reviewLocalHome.class);

Good Luck,
Avi.

Hi Avi,
the normal cast is totally ok here cause he is using the Local interface. And in this case no narrow is required.

bye

[Avi Abrami]

Oliver, just because the interface name has "local" in it, doesn't mean it's a local interface. Part of what determines whether an interface is local, or not, is the "ejb-jar.xml" deployment descriptor file.

Good Luck,
Avi.

Seshu,

I had the same problem. I use the Jonas Srever.

There I have the possibility to make 2(!) JNDI entries.
One (jndi) for the remote home and one (jndi-local) for the local home.
So I can choose the JNDI I need.

Good luck

Georg
