RequestDispatcher

Fields Summary

Methods Summary
public void	forward(javax.servlet.ServletRequest request, javax.servlet.ServletResponse response) Forwards a request from a servlet to another resource (servlet, JSP file, or HTML file) on the server. This method allows one servlet to do preliminary processing of a request and another resource to generate the response. For a RequestDispatcher obtained via getRequestDispatcher(), the ServletRequest object has its path elements and parameters adjusted to match the path of the target resource. forward should be called before the response has been committed to the client (before response body output has been flushed). If the response already has been committed, this method throws an IllegalStateException. Uncommitted output in the response buffer is automatically cleared before the forward. The request and response parameters must be either the same objects as were passed to the calling servlet's service method or be subclasses of the {@link ServletRequestWrapper} or {@link ServletResponseWrapper} classes that wrap them. param request a {@link ServletRequest} object that represents the request the client makes of the servlet param response a {@link ServletResponse} object that represents the response the servlet returns to the client exception ServletException if the target resource throws this exception exception IOException if the target resource throws this exception exception IllegalStateException if the response was already committed
public void	include(javax.servlet.ServletRequest request, javax.servlet.ServletResponse response) Includes the content of a resource (servlet, JSP page, HTML file) in the response. In essence, this method enables programmatic server-side includes. The {@link ServletResponse} object has its path elements and parameters remain unchanged from the caller's. The included servlet cannot change the response status code or set headers; any attempt to make a change is ignored. The request and response parameters must be either the same objects as were passed to the calling servlet's service method or be subclasses of the {@link ServletRequestWrapper} or {@link ServletResponseWrapper} classes that wrap them. param request a {@link ServletRequest} object that contains the client's request param response a {@link ServletResponse} object that contains the servlet's response exception ServletException if the included resource throws this exception exception IOException if the included resource throws this exception
