Hi All,
       I have an Entity Bean 
Home : SubNetworkHome
Remote: SubNetwork
Bean: SubNetworkBean

I have a getData() method declared inside the Remote Interface, whose
implementation is given in the Bean class. 

SubNetData  data = subNetwork.getData();
This method returns a SubNetData Object.

The SubNetData is a Serializable class.

Please find the error produced in my server.log file while I am trying to
access the getData() method.

[SubNetworkBean] TRANSACTION ROLLBACK EXCEPTION:Load failed; nested exception is: 
        java.lang.NullPointerException; nested exception is: 
        java.rmi.ServerException: Load failed; nested exception is: 
        java.lang.NullPointerException
[SubNetworkBean] java.rmi.ServerException: Load failed; nested exception is: 
[SubNetworkBean]        java.lang.NullPointerException
[SubNetworkBean] java.lang.NullPointerException

Can anybody tell me what is the problem with my Remote Interface or my Entity
Bean.

Your help will be appreciated.

Regards,
Madhu
