I have tried to deploy an sample ejb into weblogic server 6.0.
It is successful . But when I run the client, I have a execption :

Buying 100 shares of BEAS.
There was an exception while creating and using the Trader.
This indicates that there was a problem communicating with the server: 
java.rmi.RemoteException: Exception in ejbCreate(); nested exception is: 

 javax.ejb.CreateException: Failed to find environment value 
javax.naming.NameNotFoundException: Unable to resolve 
comp/env/tradeLimit/ Resolved: 'comp/env' Unresolved:'tradeLimit' ; 
remaining name ''
End statelessSession.Client...

Please help me. Thank you very much.
