<p>im trying to kick off a Runnable classes run method however i keep getting a NullPointerException,  Im using WebSpheres commonj.workmanager to get an instance of executorService.this is the code im using.</p>

<pre><code>executorService.execute(new Runnable() {
    public void run() {
        System.out.println("Inside run ()method..");
    }
});

ANY IDEAS?
</code></pre>

Are you checking whether
```
executorService
```
is null before calling
```
execute()
```
? If not, it sounds like you need to check the WebSphere docs.
