edu.uiuc.ncsa.security.servlet.AbstractServlet

org.oa4mp.client.api.servlet.ClientServlet

All Implemented Interfaces:

edu.uiuc.ncsa.security.core.Logable, Serializable, javax.servlet.Servlet, javax.servlet.ServletConfig

Direct Known Subclasses:

OA2ReadyServlet, OA2StartRequest, SimpleReadyServlet, SimpleStartRequest

public abstract class ClientServlet
extends edu.uiuc.ncsa.security.servlet.AbstractServlet

Basic Client servlet. it has the machinery in it for reading in a configuration file, setting up the ClientEnvironment and making the OA4MPService instance. It also includes a utility call for getting a cookie with the identifier (stored with the key "oa4mp_client_req_id" in the users browser).

Look at the two sample uses of this in SimpleStartRequest and SimpleReadyServlet to see how to extend and use it.

This clears the client request id cookie ("oa4mp_client_req_id") and returns the currently set value for it. This
