Generating JNLP file in portlet

[louise_za]

Hi everyone

I am trying to generate a JNLP file for Java Web Start inside a portlet. In the doView method I have the following:

rResponse.setContentType("application/x-java-jnlp-file");
javax.portlet.PortletRequestDispatcher pRD = this.getPortletContext().getRequestDispatcher(JSP_PATH + "/my_jnlp.jsp");

My jsp contains the following code:

<%@ page contentType="application/x-java-jnlp-file" %>
<%@ page session="false"%>

<%
//get some application variables here
...
...
System.out.println("Executing the JSP");
%>

<jnlp spec="1.0+" codebase="<%=codebase %>">

 <information>
 <title>ABC</title>
 <vendor>XYZ</vendor>
 <description>Foo</description>
 </information>

 <resources>
 <j2se version="1.5+" />
 <jar href="ABC.jar" />
 </resources>

 <applet-desc documentBase="http://<%=web_host %>" name="RST" main-class="MyClass" width="527" height="428">
 <param name="a" value="<%=a_val %>"/>
 <param name="b" value="<%=b_val%>"/>
 </applet-desc>

</jnlp>

I have added the following to portlet.xml under the appropriate portlet:

<supports>
 <mime-type>application/x-java-jnlp-file</mime-type>
 <portlet-mode>VIEW</portlet-mode>
</supports>

Also, in the web.xml file in jboss-portal-2.2.0-bundled\server\default\deploy\jbossweb-tomcat55.sar\conf, I have added:

<mime-mapping>
 <extension>jnlp</extension>
 <mime-type>application/x-java-jnlp-file</mime-type>
 </mime-mapping>
 <mime-mapping>
 <extension>jar</extension>
 <mime-type>application/x-java-archive</mime-type>
 </mime-mapping>
 <mime-mapping>
 <extension>jardiff</extension>
 <mime-type>application/x-java-archive-diff</mime-type>
 </mime-mapping>

The problem is that when I open the page that the portlet is on, nothing happens. The portlet does not even get rendered. Please, can anyone help?

application/x-java-jnlp-file is not a supported format. You cannot mix text/html and application/x-java-jnlp-file in the same response

Thanks for the reply!

Solution to the problem:
Have the portlet generate a string containing the jnlp content dynamically and write this out to a file at a certain location. Then, have a link inside the portlet pointing to the file - the user will click on it and the java web start sequence will initiate.
