Hallo,
I have the following problem:

In a servlet (not generated from a jsp file) in the function doGet() I
will create in dependency of different input parameters different jsp
files and I will call the generated jsp file.
 
I can create the jsp-Code with...

public void doGet(
  javax.servlet.http.HttpServletRequest request,
  javax.servlet.http.HttpServletResponse response)
  throws javax.servlet.ServletException, java.io.IOException {

        String text = null;
        text =        "<%@ page import=\"java.util.*\"%>";
        text = text + "<%@ page
contentType=\"text/html;charset=iso-8859-1\"
%>";
        text = text + "<jsp:useBean id=\"edi\" scope=\"session\"
class=\"jsp.MyClass\" />";
        text = text + "<%";
        text = text + " here: call functions...";
        text = text + "%>";
        text = text + "<html><head>head>";
        text = text + "<body>xxxx</body></html>";
        response.setContentType("text/html");
        PrintWriter out = new PrintWriter(response.getOutputStream());
        out.println(text);
        out.close();
 }

...and I see this code im my browser. But it will not create java
code, no code is executes.



With...

public void doGet(
  javax.servlet.http.HttpServletRequest request,
  javax.servlet.http.HttpServletResponse response)
  throws javax.servlet.ServletException, java.io.IOException {

  response.sendRedirect("http://localhost:8080/myProject/file_xyz.jsp");
 }

...I can call a jsp file. But I have not this file ( I want to create
this file!) in the moment of call.
I can not create a temporar file and call this file with
sendRedirect()!!

Thank you for your hints, Thomas
