JTDS ClassNotFoundException

I'm tired googling for this error. Please help me. I found suggestuion to add jtds-1.3.1.jar to class path or edit your web.xml.

Please tell me how can I do that? I use Idea, Maven, Gwt and want connect to MS SQL 2008 Express.

Check that you are specifying net.sourceforge.jtds.jdbc.Driver and not net.sourceforge.jtds.jdbc.Drive when you do Class.forName(...)
