public interface ServletEndpointContext
ServletEndpointContext provides an endpoint 
  context maintained by the underlying servlet container based
  Jakarta XML RPC runtime system. For service endpoints deployed on a
  servlet container based Jakarta XML RPC runtime system, the context
  parameter in the ServiceLifecycle.init method is
  required to be of the Java type 
  javax.xml.rpc.server.ServletEndpointContext.
  A servlet container based Jakarta XML RPC runtime system implements
  the ServletEndpointContext interface. The Jakarta XML RPC
  runtime system is required to provide appropriate session, 
  message context, servlet context and user principal information 
  per method invocation on the endpoint class.
| Modifier and Type | Method and Description | 
|---|---|
| HttpSession | getHttpSession()The  getHttpSessionmethod returns the current 
  HTTP session (as ajavax.servlet.http.HTTPSession). | 
| MessageContext | getMessageContext()The method  getMessageContextreturns theMessageContexttargeted for this endpoint instance. | 
| ServletContext | getServletContext()The method  getServletContextreturns theServletContext associated with the web 
  application that contain this endpoint. | 
| java.security.Principal | getUserPrincipal()Returns a  java.security.Principalinstance that 
  contains the name of the authenticated user for the current
  method invocation on the endpoint instance. | 
| boolean | isUserInRole(java.lang.String role)Returns a boolean indicating whether the authenticated user
  for the current method invocation on the endpoint instance
  is included in the specified logical "role". | 
MessageContext getMessageContext()
getMessageContext returns the 
  MessageContext targeted for this endpoint instance.
  This enables the service endpoint instance to acccess the 
  MessageContext propagated by request
  HandlerChain (and its contained Handler 
  instances) to the target endpoint instance and to share any 
  SOAP message processing related context. The endpoint instance
  can access and manipulate the MessageContext 
  and share the SOAP message processing related context with
  the response HandlerChain.MessageContext, this method returns
          null.java.lang.IllegalStateException - if this method is 
           invoked outside a remote method implementation by 
           a service endpoint instance.MessageContext, 
HandlerChain, 
Handlerjava.security.Principal getUserPrincipal()
java.security.Principal instance that 
  contains the name of the authenticated user for the current
  method invocation on the endpoint instance. This method returns
  null if there is no associated principal yet. 
  The underlying Jakarta XML RPC runtime system takes the responsibility
  of providing the appropriate authenticated principal for a 
  remote method invocation on the service endpoint instance.java.security.Principal for the 
           authenticated principal associated with the current
           invocation on the servlet endpoint instance;
           Returns null if there no authenticated
           user associated with a method invocation.PrincipalHttpSession getHttpSession()
getHttpSession method returns the current 
  HTTP session (as a javax.servlet.http.HTTPSession). 
  When invoked by the service endpoint within a remote method 
  implementation, the getHttpSession returns the 
  HTTP session associated currently with this method invocation. 
  This method returns null if there is no HTTP 
  session currently active and associated with this service 
  endpoint. An endpoint class should not rely on an active 
  HTTP session being always there; the underlying Jakarta XML RPC
  runtime system is responsible for managing whether or not 
  there is an active HTTP session.
  The getHttpSession method throws JAXRPCException 
  if invoked by an non HTTP bound endpoint.
null if there is
           no active session.JAXRPCException - If this method invoked by any 
                           non-HTTP bound endpointHttpSessionServletContext getServletContext()
getServletContext returns the 
  ServletContext associated with the web 
  application that contain this endpoint. According to 
  the Servlet specification, There is one context per web
  application (installed as a WAR) per JVM . A servlet 
  based service endpoint is deployed as part of a web 
  application.ServletContextServletContextboolean isUserInRole(java.lang.String role)

               of the roleboolean indicating whether the
           authenticated user associated with the current
           method invocation belongs to a given role;
