Question

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.

executorService.execute(new Runnable() {     public void run() {         System.out.println('Inside run ()method..');     } });  ANY IDEAS? 

Answer 1

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