include

public void include(javax.servlet.ServletRequest servletRequest,
                    javax.servlet.ServletResponse servletResponse)
             throws javax.servlet.ServletException,
                    java.io.IOException

Description copied from interface: javax.servlet.RequestDispatcher

Includes the content of a resource (servlet, JSP page, HTML file) in the response. In essence, this method enables programmatic server-side includes.

The javax.servlet.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 javax.servlet.ServletRequestWrapper or javax.servlet.ServletResponseWrapper classes that wrap them.

Specified by:

include in interface javax.servlet.RequestDispatcher

---

forward

public void forward(javax.servlet.ServletRequest servletRequest,
                    javax.servlet.ServletResponse servletResponse)
             throws javax.servlet.ServletException,
                    java.io.IOException

Description copied from interface: javax.servlet.RequestDispatcher

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 javax.servlet.ServletRequestWrapper or javax.servlet.ServletResponseWrapper classes that wrap them.

Specified by:

forward in interface javax.servlet.RequestDispatcher

---

error

void error(javax.servlet.ServletRequest servletRequest,
           javax.servlet.ServletResponse servletResponse)
     throws javax.servlet.ServletException,
            java.io.IOException

---

dispatch

void dispatch(javax.servlet.ServletRequest servletRequest,
              javax.servlet.ServletResponse servletResponse,
              int filterType)
        throws javax.servlet.ServletException,
               java.io.IOException

---

toString

public java.lang.String toString()

Description copied from class: java.lang.Object

Convert this Object to a human-readable String. There are no limits placed on how long this String should be or what it should contain. We suggest you make it as intuitive as possible to be able to place it into System.out.println() 55 and such.

It is typical, but not required, to ensure that this method never completes abruptly with a java.lang.RuntimeException.

This method will be called when performing string concatenation with this object. If the result is null, string concatenation will instead use "null".

The default implementation returns getClass().getName() + "@" + Integer.toHexString(hashCode()).
