Overcoming : "AxisFault: Timeout waiting for connection" issue

This issue[1] you might face when you run your axis2client code in a loop  against a service..

To overcome above issue, set the "MULTITHREAD_HTTP_CONNECTION_MANAGER" property in the axis2 ConfigurationContext.

ConfigurationContext configContext =   ConfigurationContextFactory.  createConfigurationContextFromFileSystem("CARBON_HOME\\repository\\deployment\\client", "CARBON_HOME\\repository\\conf\\axis2_client.xml");

MultiThreadedHttpConnectionManager httpConnectionManager =  new MultiThreadedHttpConnectionManager();       

configContext.setProperty(HTTPConstants.MULTITHREAD_HTTP_CONNECTION_MANAGER,  httpConnectionManager);
