1. Do not use the session bean to access the datasource... create a data access object which locates the datasource. 2. Lookup the datasource using a jndi name not a servlet. Register your datasource with the jndi server. (Does the servlet api implement such a method ??) 3. If using a connection pool (which you should really), get the connection object out of the pool and use it to access the database.
