title: Open source threadpool lib
body: <p>I was looking for open source thread pool lib which I can use to schedule the jobs and once that individual job is done I want some notification in the thread so that I can finish the rest of the task. Do you guys know any open source lib that is doing similar kind of work. I might be using this lib in multiple diff server.</p>
  
  <p>Basic overview of my task is I have list of items. Each items needs to be submitted to other system throgh JMS/Webservice and then wait for response for each items being processed and do the rest of the task.</p>
  
  <p>Thanks in advance</p>
