Summary: NoSuchMethod-Error calling create
Initial Comment:
If the business-interface of a stateless session bean
(I just checked ssbs) extends another interface that
itself extends another one, it seems as if no create
method is generated on deployment. =>
NoSuchMethodError is thrown creating an instance of
the bean.
SMALL EXAMPLE:
public interface RemoteTest extends EJBObject, Test
{...}
public interface Test extends TestAccessOne
{...}public interface TestAccessOne
{
void foo() throws RemoteException;
}
public interface TestHome extends EJBHome
{
public RemoteTest create() throws CreateException,
RemoteException;
}
public class TestImpl implements Test, SessionBean
{
....
public void ejbCreate() {}
public void foo() throws RemoteException
{
System.out.println("foo");
}
}
Accessing the bean from a client as in:
Object objref = ctx.lookup("Test");
TestHome th = (TestHome)
javax.rmi.PortableRemoteObject.narrow(objref,
TestHome.class);
Test test = th.create();
throws the NoSuchMethodError. The important part of
the stack trace is
"java.lang.NoSuchMethodError
RemoteTest $Proxy0.create()"
I checked the bug against
-JBoss 2.2.2
-JBoss 2.4.3
both versions produced the same problem
JDK was 1.3.1_01
Moving the contents of interface TestAccessOne into
interface Test solves the technical problem!!!!!!
But the technical implementation should not interfere
the business decision to move the methods to another
interface.
Cheers,
Christian Elsen

Both ways works for me but the ZIP file is the best. Just
use the "Upload and Attach File" boxes below !.

Do you want the descriptors and code as a comment? Or is it possible to attach a zip
file?

I just checked the supplied sample against JBoss in CVS and
I couldn't reproduce the problem.
