[JBoss-user] Problem with Remote Interface!!!

2001-05-12 Thread Madhu 

Hi All,
  Continuation to my earlies mail for which [EMAIL PROTECTED] has
replied, here is the complete scenario, where this problem is coming.

Please find the getData() implementation in the Entity Bean

public SubNetData getData() throws RemoteException {
System.out.println(Inside the getData of SubNetworkBean  );
m_trace.print(SubNetworkIntfBean :getData() called );
SubNetData data = new SubNetData();

data.m_name   = m_name;
data.m_domainName = m_domainName;
data.m_type   = m_type;
data.m_discvStatus= m_discvStatus;
data.m_discvDateTime  = m_discvDateTime;
data.m_neListString   = m_neListString;
data.m_configuration  = m_configuration;
data.m_neVector   = m_neVector;

return data;
}

The SubNetData which its referring is a Serializable class which I already
mentioned. 

Please find the content of the Server.log file related to this error.

[JBoss-user] Problem with Remote Interface!!!

2001-05-11 Thread Madhu 

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

Are you sure there isn't another exception that happens right before it? 
The stack trace for the actual NullPointerException would be much more 
informative - this is probably coming from your bean code.
