F:\myeino\eino\WEB-INF\classes\eino\GetUserIdentity.class
My servlet's war locates at F:\myeino\loginwebapp.war
My jsp locates at F:\myeino\eino\error.jsp
>From servlet,I call jsp at follow statements:
String str="hello";
request.setAttribute("jsp",str);
/*follow statement is 183 line,when I execute follow statement,I got error*/
getServletConfig().getServletContext().getRequestDispatcher("loginwebapp/error.jsp").forward(request,response);
My jsp is follows:
<%@ page contentType="text/html; charset=GBK" %>
<html>
<head>
<title>
error
</title>
</head>
<body>
<h1>
JBuilder Generated JSP

<%
String message;
message=(String)request.getAttribute("jsp");
out.write("<H1>"+message+"</H1>");
%>
</body>
</html>
