Hi, I have developed a application thru' jdeveloper. I created the .ear file also using the same. As I would like to run the application using Sun One Server, I deployed the .ear in Sun One. Also I have cofigured JDBC Resource and Connection Pools. After finishing the deployment, while restarting I am getting the exception in the server console as, SEVERE: WEB0117: Error loading web module [test:web.war] in virtual server [server1]: javax.naming.InvalidNameException: Real JNDI name cannot be empty for jdbc/testDS Pls help to solve the above problem.... Thanks in advance.
