Hello!

I've written a Java program that connects to MySQL.
This works fine.

But when I try to use the same Java-file as a .jws file (as a web service on TomCat/AXIS), I get the error(this is pasted from the tomcat cmd-prompt window):

my comment: connect2db failed

It is the same file, and this doesn't happen when I run it as a regular java file.
So as a java-file it connects to MySQL, but when used under AXIS it don't.

I use a MySQL ODBC 3.51, but this is a "User DSN" ODBC, not "System DSN".
The portnumber is default: 3306
My tomcat web server uses port standard 8080.

Could this be the problem?

The problem is also that I can't use the MySQL ODBC as System DSN beacuse I can't find it on the list of availabe ODBC types under "System DSN".

Or is the problem something else?
My classpath is:

You should probably also have the driver jar in WEB-INF/lib of your web app
