ActionForm form,
HttpServletRequest request,
HttpServletResponse response)
throws IOException, ServletException, NamingException {
testSessionEJBHome testSessionBean;
InitialContext ctx=new InitialContext();
Object objref = ctx.lookup("SessionEJB");
testSessionBean = (testSessionEJBHome)PortableRemoteObject.narrow(ob jref,testSessionEJBHome.class);
TestFormBean tform = (TestFormBean) form;
request.setAttribute("TestFormBean", tform);
String name=tform.getIpString();
String tmpStr = "Welcome " + name + " !";
