Question

I’m having trouble with JDBC Connection Pooling, I’ve done all the same with explained here: JNDI Resources HOW-TO, and here is also question (the same configuration with mine) regarding this topic which has not been resolved, I think.
What else should I consider?

I hope you have done the ResourceLink configuration to your webapp, too.

  <ResourceLink global="jdbc/MyDS" name="jdbc/MyDS" type="javax.sql.DataSource" />
