[jboss-user] [JBoss Portal] - 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?
