Package com.highdeal.hci.http

Class HttpMessageSender

java.lang.Object

com.highdeal.hci.http.HttpMessageSender

All Implemented Interfaces:

MessageSender

public class HttpMessageSender
extends Object
implements MessageSender

Your client application must use an HttpMessageSender to send HCI messages and receive corresponding results using the HTTP protocol via HCI; Asynchronous or synchronous communications are possible. You use the HttpMessageSenderFactory to instantiate such a Java class.

This HttpMessageSender defines Java classes and method to send

Implementation in Your Client Application

Use the HttpMessageSenderFactory class to instantiate an HttpMessageSender object.

Important Note

This Java class should not be instantiated directly, but obtained through the HttpMessageSenderFactory class.

Use benefit from the asyncSend(..) and send(..) methods to manage the communications between your client application and the connected SAP CC system.

Method Summary

Modifier and Type	Method	Description
void	addRedirectHandler(MessageSender.IRedirectHandler redirectHandler)	Adds a redirection handler to this MessageSender; This handler is notified of redirection events.
MessageContext	asyncSend(MessageEnvelope env, ClientMessageListener listener)	Sends a HCI message and receives notification of progress and upon termination of the message process via a dedicated listener.
MessageContext	asyncSend(MessageEnvelope env, ClientMessageListener listener, Map<String,String> headers)
URL	getServerUrl()	Returns the URL of the server on which the MessageSender is connected.
SystemStatus	getSystemStatus(MessageOriginator ori)	Returns the current system status.
void	removeRedirectHandler(MessageSender.IRedirectHandler redirectHandler)	Removes a MessageSender.IRedirectHandler from this MessageSender; The handler is not be notified anymore of redirection events.
MessageEnvelope	send(MessageEnvelope message)	Sends a HCI message and receives its results via the HCI technical interface; The communications are synchronous.
MessageEnvelope	send(MessageEnvelope message, int timeout)	Sends a HCI message and receives its results via the HCI technical interface; this method is protected by a timeout, that means that, if the SAP CC system does not answer within the timeout, a communication failure is sent.
MessageEnvelope	send(MessageEnvelope message, int timeout, Map<String,String> headers)
MessageEnvelope	send(MessageEnvelope message, Map<String,String> headers)

                     throws CommunicationFailureException,
BadMessageFormatException

Description copied from interface: MessageSender

Sends a HCI message and receives its results via the HCI technical interface; The communications are synchronous.

Specified by:

send in interface MessageSender

Parameters:

message - The message to send

Returns:

The resulting message

Throws:

CommunicationFailureException - if the SAP CC system cannot be reached

CommunicationFailureException

Description copied from interface: MessageSender

Returns the current system status.

Specified by:

getSystemStatus in interface MessageSender

Parameters:

ori - a valid message originator.

Returns:

the current system status

Throws:

OperationFailureException - if the system status cannot be retrieved
