                           javax.servlet.ServletException
        Helper method to call the servlet for the current content data. If the current content data has no servlet, NOT_FOUND (404) error is sent and the method terminates.

        If the the servlet exists, the SlingConstants.SLING_CURRENT_SERVLET_NAME request attribute is set to the name of that servlet and that servlet name is also set as the currently active servlet. After the termination of the servlet (normal or throwing a Throwable) the request attribute is reset to the previous value. The name of the currently active servlet is only reset to the previous value if the servlet terminates normally. In case of a Throwable, the active servlet name is not reset and indicates which servlet caused the potential abort of the request.

        Parameters:
        request - The request object for the service method
        response - The response object for the service method
        Throws:
        IOException - May be thrown by the servlet's service method
        javax.servlet.ServletException - May be thrown by the servlet's service method
