Invoking the Dynamically Created JNLP

Question

Unfortunately I do not seem to be getting any responses to my questions in this group:( However, I am still hoping that someone may know the answer to this.
I have a portlet that is forwarding the request to a JSP file that creates the dynamic JNLP file.
I see the contents of this JNLP file in the source of the page served, but I was hoping that the forwarding of the request will launch Java Web Start.
The contents of the JSP file are
<%@ page session="false"%>
<%@ page contentType="application/x-java-jnlp-file" info="My JNLP"%>
<%
StringBuffer codebaseBuffer = new StringBuffer();
codebaseBuffer.append(!request.isSecure() ? "http://" : "https://");
codebaseBuffer.append(request.getServerName());
if (request.getServerPort() != (!request.isSecure() ? 80 : 443))
codebaseBuffer.append(':');
codebaseBuffer.append(request.getServerPort());
codebaseBuffer.append('/');
%>
<?xml version="1.0" encoding="UTF-8"?>
<jnlp spec="1.0+"
codebase="<%= codebaseBuffer.toString() %>"
     href="<%= request.getRequestURI() %>">
     <information>
          <title>Sample</title>
          <vendor>Sample Web Start Application</vendor>
          <offline-allowed/>
          <icon href="salpro-icon.gif"/>
     </information>
     <resources>
          <j2se version="1.4+"/>
          <jar href="resources/JNLPTime.jar"/>
     </resources>
<application-desc main-class="J2.ws.TheTime"/>
</jnlp>
A portion of the source page that is served :
<?xml version="1.0" encoding="UTF-8"?>
<jnlp spec="1.0+"
codebase="http://mharidasa.almaden.ibm.com:8421/"
     href="/ibm/PA_1_0_2B4/resources/J2JWS.jsp">
     <information>
          <title>Sample</title>
          <vendor>Sample Web Start Application</vendor>
          <offline-allowed/>
          <icon href="salpro-icon.gif"/>
     </information>
     <resources>
          <j2se version="1.4+"/>
          <jar href="resources/JNLPTime.jar"/>
     </resources>
<application-desc main-class="J2.ws.TheTime"/>
</jnlp>
How can I make the server invoke the JNLP as opposed to serving it back?
Your suggestions are very much appreciated.
thank you - Minnie

Hi! I am doing a similar project where I have a jsp
that calls the jnlp using this url:
http://c37ts014/myserver/server/servlet/WebStartUpload.
nlp?documentid=123&documentname=test
How can I get the values of my parameters namely
documentid and documentname inside my app? Is there a
way where I need not have to create my jnlp
dynamically then? If not, would it be ok to ask how
you did your dynamic loading through jsp?
Hope you can help me. Thanks.I experimented with this heavily yesterday (using oracle app server , but it is the same idea) and could not get it to work with parameters on both the jnlp and jar resource hrefs, however it can work with parameters on the homepage href. Too bad, there seems to be no reason why it shouldn't work with parameters in all situations unless it has some security implication that I'm not aware of.
