Classes and Methods

2-8  Oracle Communication and Mobility Server Developer’s Guide

Outside of the service method, the doRequest() and doResponse() are the 
broadest methods provided by the SipServlet class. These methods enable tasks 
that are independent of the received method or response. You can extend methods to 
perform specific request and response handling tasks. 

Extend the following methods for request handling:

■

doInvite

 – for SIP INVITE requests

■

doAck

 – for SIP ACK requests

■

doCancel

 – for SIP CANCEL requests

■

doBye

 – for SIP BYE requests

■

doOptions

 – for SIP OPTIONS requests

■

doRegister

 – for SIP REGISTER requests

■

doSubscribe

 – for SIP SUBSCRIBE requests

■

doNotify

 – for SIP NOTIFY requests

■

doMessage

 – for SIP MESSAGE requests

■

doInfo

 – for SIP INFO requests

■

doPrack

 – for SIP PRACK requests

For response handling, extend the following:

■

doProvisionalResponse

 – for SIP 1xx informational responses

■

doSuccessResponse

 – for SIP 2xx responses

■

doRedirectResponses

 – for SIP 3xx responses

■

doErrorResponse

 – for SIP 4xx, 5xx, and 6xx responses

SIP Messages follow the RFC 822 standard. Headers, values and content can be 
accessed through the methods in the javax.servlet.sip.SipServletMessage 
interface.

Both the SipServletRequest and SipServletResponse classes extend the 
SipServletMessage

 interfaces:

■

public interface SipServletRequest extends 

javax.servlet.ServletRequest,SipServletMessage

■

public interface SipServletResponse extends 

javax.servlet.ServletResponse, SipServletMessage

SipServletRequest

 and SipServletResponse objects in the SIP servlet methods 

doRequest

 and doResponse are implementations of the SipServletRequest 

interface and the SipServletResponse interface which both extend the 
SipServletMessage

 interface from the javax.servlet.sip package.

All of these response handling methods, as well as the doAck 

and doCancel request handling methods, are empty. The remaining 
request handling methods respond to a request with a 500 Response 
(Internal Server Error).
