[jboss-user] [Beginners Corner] - java.lang.IllegalArgumentException: wrong number of argument

[Shaelen]

I am trying to invoke a method of a stateless session bean from a remote java client and am seeing the following exception:

java.lang.IllegalArgumentException: wrong number of arguments

Does anybody have any insight as to what the cause of this may be?
