Calling Java methods in a GWT module via Javacript of a Google Gears worker in a workerpool

Question

I would like to know if it would be possible to call Java method of a GWT module within a worker in a Google Gears workerpool. For example given the class and method of a GWT module.

package com.mycomp;
public class MyClass implements EntryPoint, WorkerPoolMessageHandler {
public void mymethod() {
  ...
}}

I have tried defining the following JSNI method

private native String javamethod() /*-{

  var workerCode = 'google.gears.workerPool.onmessage = function(a,b,message) { google.gears.workerPool.sendMessage(update(),message.sender); };';

  function update() {
   [email protected]::mymethod();
   return "Done";
  };

  workerCode += String(update);

  return workerCode;

 }-*/;

and use the following code to define a worker to invoke mymethod().

WorkerPool wp = Factory.getInstance().createWorkerPool();
wp.setMessageHandler(this);
int workerId = wp.createWorker(javamethod());
wp.sendMessage("update", workerid);

But this seems to be not possible. It would be great if someone could let me know if there is another way.

Thanks for the help.
