Unknown exception. Pls help

When trying to access a stateless session ejb hosted in solaris Sun ONE Application Server 7.0.0_03b, I am getting the following exception:-

Unknown error: class java.rmi.ServerException: RemoteException occurred in server thread; nested exception is:

java.rmi.RemoteException: nested exception is: java.lang.NullPointerException; nested exception is:

java.lang.NullPointerException

java.rmi.ServerException: RemoteException occurred in server thread; nested exception is:

java.rmi.RemoteException: nested exception is: java.lang.NullPointerException; nested exception is:

java.lang.NullPointerException

at com.sun.corba.ee.internal.iiop.ShutdownUtilDelegate.mapSystemException(ShutdownUtilDelegate.java:68)

at javax.rmi.CORBA.Util.mapSystemException(Util.java:65)

But this exception does not happen if i deploy the ejb on the same application server's windows version.

Can you please help. Any clues?

Thanks in advance,

Vinod
