Perhaps this might help? http://www.rgagnon.com/javadetails/java-0508.html Unless you wanted to link to the java page? If so upload the java class to the WEB-INF directory and then in the form action make it link to /servlet/classname?

Or if you wanted to retrieve form data: String resName = request.getParameter("formfieldname"); in the class.
