Hi, I'm trying to call a jar thru a jsp page.
The jsp is recognizing the class I use in the jar, but when I run the jsp, I get an exception that I really don't know how to deal with.
please help... :

The server encountered an internal error () that prevented it from fulfilling this request.

exception

....

Usually this indicates that the jar hasn't been deployed to the
server. If it's not in the WEB-INF/lib folder of your Dynamic Web
Project, you might need to go to the project's Java EE Module
Dependencies property page (select Properties from the project's
context menu) and tell it to include the jar.
