There can be two errors, first the connections in the application server are not configured correctly or second the jndi name of your datasources is wrong. I don't know it exactly, but must it not something like "jdbc/dbname" ?
I’ve looked at a lot of different solutions, and in my humble opinion Aspose is the way to go. Here’s the link: http://aspose.com
