JNDI lookup of datasource objects.
Is there a way to configure Tomcat so I can lookup datasoruce objects by doing .lookup(jdbc/someName) instead of .lookup(java:comp/env/jdbc/someName). I'm trying to work locally on a webphere project using Tomcat / Netbeans. In Webphere lookups are done using jdbc/someName.

RE: Cannot load JDBC driver class 'null' - Tomcat standalone 4.1. 27 w hen trying instantiate datasource object.
Reply to myself. Dam - commons-dbcp.jar does not support: getConnection(String uname, String passwd) throws SQLException. Only. getConnection() throws SQLException I guess I need to talk to the comons-dbcp group. So why did I have to move the resources to the webApp group to make this work? P.S. - So moving the resources to the webApp context did fix my problem.

RE: how to use single dbcp resource across multiple webapps
Paul, I just went through this exercise today. (See msgs with subject = java.sql.SQLException: Cannot load JDBC driver class 'null') I do not know why it does not work when set up in the global context(Tomcat admin puts datasources here). Let us know if you get an answer.
