ohair@286 29 * JAX-WS 2.0.1 runtime. </p>

ohair@286 37 * <H3>Message Flow</H3>
ohair@286 38 * <P>A Web Service invocation starts with either the
ohair@286 39 * {@link com.sun.xml.internal.ws.transport.http.servlet.WSServletDelegate WSServletDelegate}
ohair@286 40 * or the {@link com.sun.xml.internal.ws.transport.http.server.ServerConnectionImpl ServerConnectionImpl}.
ohair@286 41 * Both of these classes find the appropriate {@link com.sun.xml.internal.ws.server.RuntimeEndpointInfo RuntimeEndpointInfo}
ohair@286 42 * and invokes the {@link com.sun.xml.internal.ws.server.Tie#handle(com.sun.xml.internal.ws.api.server.WSConnection,
ohair@286 43 * com.sun.xml.internal.ws.spi.runtime.RuntimeEndpointInfo) Tie.handle}
ohair@286 44 * method. This method first creates a {@link com.sun.pept.ept.MessageInfo MessageInfo}
ohair@286 45 * used to gather inforrmation about the message to be received. A
ohair@286 46 * {@link com.sun.xml.internal.ws.server.RuntimeContext RuntimeContext}
ohair@286 47 * is then created with the MessageInfo and the {@link com.sun.xml.internal.ws.api.model.SEIModel RuntimeModel}
ohair@286 48 * retrieved from the RuntimeEndpointInfo. The RuntimeContext is then
ohair@286 49 * stored in the MessageInfo. The {@link com.sun.pept.ept.EPTFactory EPTFactory}
ohair@286 50 * is retrieved from the {@link com.sun.xml.internal.ws.server.EPTFactoryFactoryBase EPTFactoryFactoryBase}
ohair@286 51 * and also placed in the MessagInfo. A {@link com.sun.pept.protocol.MessageDispatcher MessageDispatcher}
ohair@286 52 * is then created and the receive method is invoked. There will be two
ohair@286 53 * types of MessageDispatchers for JAX-WS 2.0.1, SOAPMessageDispatcher
ohair@286 54 * (one for client and one for the server) and an XMLMessageDispatcher
ohair@286 55 * (one for the client and one for the server).</P>
ohair@286 56 * <P>The MessageDispatcher.receive method orchestrates the receiving of
ohair@286 57 * a Message. The SOAPMessageDispatcher first converts the MessageInfo
ohair@286 58 * to a SOAPMessage. The SOAPMessageDispatcher then does mustUnderstand
ohair@286 59 * processing followed by an invocation of any handlers. The SOAPMessage
ohair@286 60 * is then converted to an InternalMessage and stored in the
ohair@286 61 * MessageInfo. The converting of the SOAPMessage to an InternalMessage
ohair@286 62 * is done using the decoder retrieved from the EPTFactory that is
ohair@286 63 * contained in the MessageInfo. Once the SOAPMessage has been converted
ohair@286 64 * to an InternalMessage the endpoint implementation is invoked via
ohair@286 65 * reflection from the Method stored in the MessageInfo. The return
ohair@286 66 * value of the method call is then stored in the InternalMessage. An
ohair@286 67 * internalMessage is then created from the MessageInfo. The SOAPEncoder
ohair@286 68 * is retrieved from the EPTFactory stored in the MessageInfo. The
ohair@286 69 * SOAPEncoder.toSOAPMessage is then invoked to create a SOAPMessage
ohair@286 70 * from the InternalMessage. A WSConnection is then retrieved from the
ohair@286 71 * MessageInfo and the SOAPMessage is returned over that WSConnection.</P>

ohair@286 101 * updated with logical handler' Source. Need to verify if this
