Message:
Servlet JSP Communication
Posted by Ashok on December 06, 2000 at 4:11 AM
Hi all, I would really appreciate if anybody can help me out on this one.
I am using the following Servlet Code and a JSP file. The Servlet uses the RequestDispatcher.forward method to send a value to the JSP. I get the following error:
***
The servlet named UpdateJSPTest at the requested URL http://65.2.232.35:8080/servlet/UpdateJSPTest reported this exception: Can not forward to servlet file : OutputStream or writer has been obtained. Please report this to the administrator of the web server.
***
It also reports an IllegalStateException and points to the line in the Servlet code which is: rd.forward(req, res); The JSP file runs perfectly OK when I call it from the location bar on the browser(except that null is returned). I am using JavaWebServer2.0. I fiddled around with java.policy and a few other things. Nothing seems to work. I think it is a very trivial problem which i am not able to figure out. HELP!!!!!!!! Servet Code:
***************************************
public class UpdateJSPTest extends HttpServlet
{
public void doGet(HttpServletRequest req, HttpServletResponse res)
throws ServletException, IOException
{
String message = "This is a test";
req.setAttribute("message", message);
PrintWriter out = res.getWriter();
RequestDispatcher rd = getServletContext().getRequestDispatcher("http://65.2.232.35:8080/index.html");
rd.forward(req,res); }
}
*******************************************
JSP CODE:(note that < and > replaced with *) *html*
*head*
*/head*
*body*
*h1**/h1*
*servlet code=UpdateJSPTest**/servlet*
*%
String message = (String) request.getAttribute("message");
out.print("message: *b*" + message + "*/b*");
%*
*p*
*ul*
*%
for (int i = 0; i * 5; i++)
{
out.println ("*li*" + i);
}
%*
*/ul*
*/body*
*/html* *****************************************
