Goto "JDBC driver list:" Add your SQL Driver: Here you have to define Name(datasource name) Implementaion class : Which is Driver specific. Class path: Here mention your driver .jar file location. and Next Goto "Data Source defined in the JDBC driver selected above:" Name : same one u have mentioned above. JNDI name : jdbc/[datasource name] User_id : Your DB user_id Password : Your DB password The other settings leave as it is. Next goto "Resource Properties defined in the data source selected above:" Click "Add" Name : serverName Type : java.lang.String Value : < Your Server Name > same way define "portNumber" and "URL" I hope this will clear to you... Goodluck, Shanmugam.
