/**
 * <p>A MQ SOAP Service is a class that implements SOAPService interface and
 * may be used to *register* its service to a MQSOAPServlet as a SOAP
 * service and becomes part of the MQ SOAP Service frame work.
 *
 * <p>A MQ SOAP service consists of the following components:
 *
 * <p>1. Request Handler Chain.  The Request handler can be registered as follows
 * in the web.xml:
 *
 * <p>mq.soap.request.handler.#="MessageHandler class full name"
 *
 * <p>For example,
 *
 * <p>mq.soap.request.handler.1=com.sun.TestMessageListener1
 * <p>mq.soap.request.handler.2=com.sun.TestMessageListener2
 *
 * <p>2. Response Handler Chain.  The Response handler can be registered as
 * follows in the web.xml:
 *
 * <p>mq.soap.response.handler.#=MessageHandler class full name.
 *
 * <p>For example,
 *
 * <p>mq.soap.response.handler.1=com.sun.TestMessageListener1
 * <p>mq.soap.response.handler.2=com.sun.TestMessageListener2
 *
 * <p>3. A service() method to be over ridden by subclass.
 *
 * <p>4. Service lifecycle management methods.  There are four methods defined
 * for life cycle management - init/start/stop/close.  They are used for
 * init/start/stop/close a MQ SOAP Service instance.  Sub class SHOULD
 * implement or over ride the life cycle methods if necessary.
