title: How to launch a Java Web start application with dynamic parameters
body: <p>I'm trying to migrate a Java applet to a Java web start application. The applet was activated from a JavaScript with several parameters, some are not hard-coded (<code>sessionId</code>, <code>tempFilePath</code>):</p>
  
  <pre><code>deployJava.runApplet(attributes, parameters);
  </code></pre>
  
  <p>In order to migrate the applet I'm using a simple JNLP file with <code>applet-desc</code> tag. And from the JavaScript I call:</p>
  
  <pre><code>deployJava.launchWebStartApplication('$jnlp_path');
  </code></pre>
  
  <p>I just can't understand how to pass to the web start application the parameters that were created by the JavaScript.</p>
