title: How to run a thread inside a webservice
body: <p>Could someone help me on this,</p>
  
  <p>I have created simple web services using axis2 , apache and tomcat. This web service has a queue that keeps xml files sent from a client, so whenever a client calls a method on the webservice, the webservice loads this xml to its queue. Now I want to have a thread running in the webservice which monitors this queue, and if there are items in the queue takes some action.</p>
  
  <p>But my problem is that the webservice is invoked only if a client calls one of the methods on its interface. But I need this thread to be running on webserbice. Could someone tell me is there are is a way to do this?</p>
  
  <p>When a client invokes a method on the webservice, it does not consider previous method invocations. This means that it does not keep track of data in the queue, for each invocation it creates new queue.</p>
