If you are using Jacob from within some web applications handled by Tomcat, you must not put jacob.jar in the WEB-INF/lib directories of the webapps.

If you fail to comply, the first application using a given dll will work; subsequent webapps will fail with a message like "already loaded in another classloader".

Putting jacob.jar in the common/lib directory solves the problem (there is only one classloader for common/lib).

BUT! You ought to put this simple facts in the UsingJacob.html file! please!

This problem is quite difficult to identify, and I think is quite common (lots of unanswered questions in the forums).

TIA
