Thankyou Ingo,

this solved my problem.
 if (manager == null) {
manager = new MultiThreadedHttpConnectionManager();
 manager.setMaxTotalConnections(30);
manager.setMaxConnectionsPerHost(10);
  }
  client = new HttpClient(manager);

  Is this instance comes from SimpleConnectionManager ??
 
 Simple answer, yes.
 
 Two notes:
 - Don't use UrlGetMethod. It's deprecated. Just use GetMethod.
 - As a first solution try to surround the following two lines of your

   int status = client.executeMethod(getMethod);

This is how I am getting the Client Instance.

  org.apache.commons.httpclient.HttpURL url = (org.apache.commons.

  org.prithvi.docparser.microsoft.msexchange.apache.OwaWebdavResource

  //get the client session
  client = webDavResourceFile.retrieveSessionInstance();

Is this instance comes from SimpleConnectionManager ??
