It's because jdbc is not a datasource, it's a container (or something
similar. I have not the time to look it up).
In your server.xml/web.xml files you should have a resource that's probably
named "jdbc/myConnection".
Your code should read
dataSource2=(DataSource)ctx.lookup( "java:comp/env/jdbc/myConnection" );
This of course is a guess. Without your config file, it's hard to tell.
