I'm using JSP and MySQL to make a simple message board.  I have a Connection pool that works well on my Tomcat localhost installation.  On my machine, I put the connection pool and other classes that I intend to use for multiple webapps in the classes directory immediately under the tomcat home directory.  Since there doesn't appear to be an analogous directory in Resin, I put the connection pool class in the WEB-INF/classes directory of my only lunarpages webapp.  

Here's the problem:  When I upload the connection pool classes, the connections seem to work for a short time.  However, it appears the they soon stop functioning.  

I'm confident that the class is good b/c I've used it successfully for a long time and the only thing I changed was the DB, user, pwd in the mm.mysql string.  Could the initial instantiation be dying somehow?  I have to restart Tomcat each time I change a class, so I'm wondering if the differences with Resin are contributing to the problem.  

Another related question:  is there a "super" classes directory in Resin like there is with Tomcat?  I tried creating a classes directory under public_html, but it didn't seem to have the same effect.  

I'm planning to install Resin on my machine in the near future, but in the meantime, any help would be greatly appreciated as I'm at a complete loss for ideas.  (Sorry this is so long...)

I'm pleased you got it fixed.
