java.lang.IllegalArgumentException: wrong number of argument

[vijayk]

Hello All,

I am trying to pass a simple Java bean (AuthenticateUserCommand) to a stateless EJB's method. And I get this stack trace. Can someone help me understand this? I am trying for a week now and still cant solve this.

Thanks,
Vijay
