Deployment Error using j2ee1.2

[Shalaj Jain]

i am doing a simple ejb program which has to print hello on console.
i have compiled the home interface,remote interface and the bean successfully.
i have added the classes to make the jar file and set up the JNDI name.
but when i am deploying ,i am getting the following error:
"There was a deployment error.java.rmi.ServerException: RemoteException occured in sever thread; nested exception is: java.rmi.RemoteException: Error saving/opening" This error pops up as a message box during the "Deployment Progress Screen". The main window states: "Deployment Error: Bad mapping of key {0} to class {1}; not found: com.sun.enterprise.deployment.xml.ApplicationNode"
i am using jdk1.2 and
j2eesdk 1.2 version.
please help, i'm not able to make heads or tails of it

What appserver are you deploying to?

I think it is J2EE RI.
