The flow of calling entity bean is as under:
1) loginValidate.jsp
2)com.nextgen.security.MuserAccessBean
i)findByUsername
3)Entity Bean com.nextgen.security.Muser
Where could be the problem here in client side or server side???
Thanks in advance.

HI There ,
i have the Same Problem, i have donwload the Websphere 4.0.1
Single Advance Edition, and i have installed my EAR File, but when i run
the Client to Access the EJB , i have the Same Exception Above.
i have Fixed this problem by Installing the Fix Pack 4.0.3 .
so i recommnded that you insatll the Fix Pack for your Websphere Version. and you problem will be Solved Completley.
Have Fun
