Method Detail

setLogin

public void setLogin(boolean isLogin)

isModified

public boolean isModified()

getAsyncInvocation

public Invocation getAsyncInvocation()

forward

public void forward(ServletRequest request,
                    ServletResponse response)
             throws ServletException,
                    java.io.IOException

Description copied from interface: RequestDispatcher

Forwards the request to another page. Forward may not be called if data has been sent to the client. Specifically, forward calls the response.reset() method to clear the output buffer.

Query parameters are added to the original query parameters.

The new URI values are based on the RequestDispatcher URI. So getRequestURI(), getServletPath(), and getPathInfo() will reflect the request dispatcher URI.

Specified by:

forward in interface RequestDispatcher

Parameters:

request - the original request

response - the original response

Throws:

ServletException

java.io.IOException

dispatchResume

public void dispatchResume(ServletRequest request,
                           ServletResponse response)
                    throws ServletException,
                           java.io.IOException

Throws:

ServletException

java.io.IOException

error

public void error(ServletRequest request,
                  ServletResponse response)
           throws ServletException,
                  java.io.IOException

Throws:

ServletException

java.io.IOException

dispatch

public void dispatch(ServletRequest request,
                     ServletResponse response)
              throws ServletException,
                     java.io.IOException

Throws:

ServletException

java.io.IOException

forward

public void forward(ServletRequest topRequest,
                    ServletResponse topResponse,
                    java.lang.String method,
                    Invocation invocation,
                    DispatcherType type)
             throws ServletException,
                    java.io.IOException

Forwards the request to the servlet named by the request dispatcher.

Parameters:

topRequest - the servlet request.

topResponse - the servlet response.

method - special to tell if from error.

Throws:

ServletException

java.io.IOException

include

public void include(ServletRequest request,
                    ServletResponse response)
             throws ServletException,
                    java.io.IOException

Description copied from interface: RequestDispatcher

Includes the result of another page.

Query parameters are added to the original query parameters.

The included request's URI methods reflect the original URI data. So getRequestURI() will return the URI sent by the browser.

Included pages should use request.getAttribute() to get the new URI values:

getRequestURI	javax.servlet.include.request_uri
getContextPath	javax.servlet.include.context_path
getServletPath	javax.servlet.include.servlet_path
getPathInfo	javax.servlet.include.path_info
getQueryString	javax.servlet.include.query_string

Specified by:

include in interface RequestDispatcher

Parameters:

request - the original request

response - the original response

Throws:

ServletException

java.io.IOException

include

public void include(ServletRequest topRequest,
                    ServletResponse topResponse,
                    java.lang.String method)
             throws ServletException,
                    java.io.IOException

Include a request into the current page.

Throws:

ServletException

java.io.IOException

dispatchResume

public void dispatchResume(HttpServletRequest request,
                           HttpServletResponse response,

                    throws ServletException,
                           java.io.IOException

Dispatch the async resume request to the servlet named by the request dispatcher.

Parameters:

request - the servlet request.

response - the servlet response.

invocation - current invocation

Throws:

ServletException

java.io.IOException

toString

public java.lang.String toString()

Overrides:
