I have been trying to move to the db connection pool of tomcat.
They both use org.gjt.mm.mysql.Driver

You have to add
con = dataSource.getConnection();
after
dataSource = (DataSource)ctx.lookup(jdbc/conversion);

I join in late, but I'm currently using CodeStudio Poolman for my

Sorry, I don't agree with you.
1. My post is not off topic
2. I spent few weeks working on the problem before my first post was done.
