That's the entire contents of the stdout log file. I don't mind moving
the vendor specific jar files to the \common\lib folder, but I would
like to make sense of why it happens as well. Note that implementing
this product is my first exposure in 15 years of programming to Java /
Apache technologies :). Not that they (.NET / IIS vs Java / Apache) are
too dissimilar, rather it's the implementation topics like this I
struggle with at the moment.
Thanks,
Tony

What error? Do you have an associated stack trace? Is there anything
in the logs?
Note that common/lib is visible not only to the webapp, but also to the
container classes. Just speculating, but if the classes in question are
used somehow for something like container-managed connection pooling,
they must be visible to Tomcat as well as the webapp.
