EJB on sun j2ee implementation

["Jason R. Kretzer" <jason@OpinionOne.com>]

Hello all,

I have decided to mess with the reference implementation of J2ee from sun.  
So, I downloaded the j2eesdk1.3.1 and installed it.  I am trying to deply a 
simple "hello world" style EJB.  Thought I would start off simple with a new 
EJB container.

Anyway, when I use the deploytool to deploy the EAR file, I get the following 
message:

[root@Fenris Calculator]# 
/home/jason/zips/webserver/j2sdkee1.3.1/bin/deploytool -deploy 
CalculatorApp.EAR localhost CalculatorClientLibrary.jar
Deploy the application in CalculatorApp.EAR on the server localhost saving the 
client jar as CalculatorClientLibrary.jar
Sender object Deploy Tool : Deploy CalculatorApplication on localhost
Remote message: Contacted Server....
Remote message: Application CalculatorApplication transferred.
Sender object Deploytool (Main) : RemoteException occurred in server thread; 
nested exception is:
        java.rmi.RemoteException: Error saving/opening


As this is my first attempt with this implementation, I have never seen this 
error before.  Can anyone tell me what I may try?  Please don't say try 
another implementation.

Thanks!
