NoSuchMethodError while invoking EJB

Question

Hi,
A session bean(ejb1) is calling another session bean(ejb2) in another ear file in the same container. I am able to invoke ejb2.
I have 3 methods - m1, m2, m3 defined in the remote interface.
when I call m1 (testEJB(String)) and I pass a String, it returns null.
when I call m2(executeTest(Map params)), I get EJB Exception: : java.lang.NoSuchMethodError
If I change m1 return type to int in the Remote interface and class, build the ear file, redeploy in weblogic and restart the weblogic.
I get NoSuchMethodError for m1 with int return type. So, my guess is somehow, weblogic still looks at the old class file and not recognizing the new/updated methods. I even tried deleting the directory under the weblogic domain when I undeploy. But it still seems to somehow find the old class file. How do I solve this? I will appreciate an immediate help on this.
Thanks a lot in advance,
Sree.

Hi Andy,
Thanks for your reply. I deleted the EJBCompileCache, all other places where I find a cache of my EJB. But I still get the NoSuchMethodError. So, I changed the name of the EJB class. Now when I try to deploy ear file (which has EJB1 refereing EJB2), it cannot find the remote interface. Looks like a classloading problem. Do I need to incude any jar files in the manifest classpath to resolve this? Please help me.
Thanks,
Sree.
