Hi,
I have strange situation. I have some SessionBean which implements some
simple interface (not anotated with @Local or @Remote). If It implements
some interface I have exception:
-------------------------------------------------
java.lang.IllegalArgumentException: object is not an instance of declaring

------------------
If I remote the "implements X" declaration there is no exception and
everythings works ok. Using Glassfish 3.0.1. Is there any explanation what
am I doing wrong? I want to not remove interface since is brings more
readability to code.
Thanks in advance.
