I found the way to do this. I had to implement "ServiceLifecycle" interface for my Web Service and provide implementation for init and destroy method. private ServletEndpointContext mServletEndpointContext = null; private ServletContext mServletContext = null; public void init(Object context) { System.out.println("Init Called"); mServletEndpointContext = (ServletEndpointContext) context; mServletContext = mServletEndpointContext.getServletContext(); } /** * */ public void destroy() { System.out.println("Destroy Called"); mServletEndpointContext = null; mServletContext = null; } You can get the user prinicipal from ServletEndpointContext .
