You can also try to merge all jar files into bigger one (usually I
call it firebirdsql-full.jar), but I doubt that it will help :(

Should not be a problem. AFAIK, Java does know nothing about
symlinks, so they are normal files to it.

connector.jar, jaas.jar and jta-spec1_0_1.jar must be there, classes
from it are used in the heart of the driver. But they became common,
so Tomcat can have its own version.

Recently I have discovered some problems with multithreaded access to
JDBC connection. But it was related to statement execution, not
opening connection. Can you try your pool with only one connection?

Can you run your Tomcat in debugger (like Borland JBuilder or
Eclipse)? Our exception handling has some places for improvement, and
debugger might help.

I will try to modify exception handling, so that we do not loose any
information. Unfortunatelly I cannot tell you how long will it take...
