1) do not top-post. Reply logically, below the question or previous message. That's the 
usage on this list.

I asked to copy and paste in the message, because this list normally strips attachments.
You're lucky, they arrived.

This being said, when looking at the files you attached, I do not really see something 
that has to do with Tomcat per se there.  I am not really the specialist here, but it 
looks like the code which fails is in the application :

etc..

You may get better help asking on the support list of the supplier of this :
org.springframework.jdbc.support
