You want to create a javax.sql.DataSource on BEA WebLogic for use in your servlets.
Use the WebLogic console to configure a new connection pool, then configure a new DataSource associated with that pool.
Configuring a WebLogic DataSource involves the following steps:
Figure 21-2. Creating a connection pool with the WebLogic console application
Figure 21-3. Creating a DataSource with the WebLogic console application
Figure 21-4 shows the WebLogic JNDI tree where the DataSource that you have just created is bound.
