Servlet removeServletMapping(java.lang.String uri)
                             throws ServletMappingException

Remove a Servlet mapping. This directs the Servlet container not to direct any more requests to a previously registered Servlet.

Parameters:

uri - the URI-mapping for the Servlet

Returns the Servlet mapped to the given URI.

Parameters:

uri - the URI-mapping for the Servlet

                                       throws ServletMappingException

Returns a Servlet request dispatcher for the Servlet mapped to the specified URI.

Parameters:

uri - the URI mapped to a Servlet

Returns:

a RequestDispatcher that can be used to dispatch requests to that Servlet

Throws:

ServletMappingException

getContextPath

java.lang.String getContextPath()

Returns the portion of the request URI that indicates the context of the request

Returns:

a String specifying the portion of the request URI that indicates the context of the request

setContextPath

void setContextPath(java.lang.String path)

Sets the portion of the request URI that indicates the context of the request
