Class ServletChain

java.lang.Object

com.ibm.websphere.servlet.filter.ServletChain

All Implemented Interfaces:

javax.servlet.RequestDispatcher

Deprecated.

Application developers requiring this functionality should implement this using javax.servlet.filter classes.

public class ServletChain
extends java.lang.Object
implements javax.servlet.RequestDispatcher

Object that chains the responses of servlets together. A servlet chain acts as a response pipe that allows servlets to filter the output of the previous servlet in the chain. When a servlet writes header or output stream data to the response, this data is fed into a chained request object that will be passed to the next servlet in the chain. The next servlet can examine the contents of the chained request to see the response that was generated by the previous servlet. The data written by the last servlet in the chain will be sent back to the client (Deprecated since WebSphere 6.0).
