Since I need my web service to be called every 15mins or so, do I need to have my servlet client configured as a Context Listener for that (which will have to call AxisServlet, which will then call my web service) or is there a simpler way to call my web service every 15mins. How can I tell the AxisServlet about which web service to call? Is it a configuration in axis2.xml? If so is there some documentation on that which will help a lot.
