Hi all,

I am trying to build a basic Login web application using Struts framework. The input login.jsp contains the input fields/properties - username,password,server and port. I also have the corresponding getters/setters in the LoginActionForm.java. But when I try to build and run this application, I get the following error message-


Apr 17, 2008 9:50:41 AM org.apache.struts.action.ActionServlet init
SEVERE: Unable to initialize Struts ActionServlet due to an unexpected exception or error thrown, so marking the servlet as unavailable. Most likely, this is due to an incorrect or missing library dependency.
