title: set param value of jnlp dynamically
body: <p>I am trying to launch applet using JNLP. I want to pass some parameter dynamically to applet. My JNLP file looks like</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="UTF-8"?&gt;
      &lt;jnlp spec="1.0+" codebase="http://localhost:8080/WebAppTest/jar/" href=""&gt;
          &lt;information&gt;
              &lt;title&gt;JNLP Test&lt;/title&gt;
              &lt;vendor&gt;Java&lt;/vendor&gt;
          &lt;/information&gt; 
          &lt;resources&gt;
              &lt;!-- Application Resources --&gt;
              &lt;j2se version="1.5+" /&gt;
              &lt;jar href="test.jar" main="true" /&gt;            
          &lt;/resources&gt;
          &lt;security&gt;
              &lt;all-permissions/&gt;
          &lt;/security&gt;
          &lt;applet-desc 
               name="Test Applet"
               main-class="com.test.TestApplet.class"
               width="100"
               height="30"&gt;
               &lt;param name="testStr" value="something" /&gt;
          &lt;/applet-desc&gt;
          &lt;update check="background"/&gt;
      &lt;/jnlp&gt;
  </code></pre>
