IllegalArgument Exception while method invocation

[mailtoagarg]

Hi,

I am using Jboss 4.2 app server and EJB3.0. A following remote method is exposed from the ejb.

void mymethod(Myclass obj)
{
}

when I invoke the mymethod() by passing null as the parameter the call goes to the EJB but when i pass a object of Myclass in it, it throws me a IllegalArgumentException. The same code works on Glassfish v2.

By using reflection on the EJB object proxy I obtained the hashcode of Myclass and the Myclass that I have deployed on the web tier. both the hashcodes were different

Let me know if I am wrong anywhere.

Regards
Ashish

Please post the entire exception stacktrace, the version of Java you are using and the bean and its interface code. Also post the client code which invokes this method.
