Synchrnous SOAP Message Scenario

Question

Hi,
I have the following scenario: <b>Sys. A -> (SOAP Request) -> XI Java Proxy -> Sys. B</b>
Basically, System A above makes a SOAP Request to XI which in turn passes on the request to System B using a Java Proxy. Now, if the request is successful, then a value of "1" is returned to System A, else a value of "0" is return if the request is unsuccessful.
I stumbled accross this statement "<i>You will use a SYNCHRONOUS MESSAGE INTERFACE to send your REQUEST MESSAGE. SO, the RESPONSE will be sent back to this Message Interface itself</i>."
If its true, please help me understand what else I need to create - besides the Data Type, Message Type, and Message Interface of the Sender System - and how the Mapping is performed in order for the response message to reach the Sender System.
I am really grateful for your response.
Thanks in advance
Reuben.

Hi,
Fault messages generally used for used for synchronous interfaces.when a proxy is generated from a message interface, an exception class is generated for a fault message type. You use this exception class to handle application errors at runtime.
d/load stefan's example where he uses fault message types:
http://de.geocities.com/stefan_grube/JavaProxyExample.zip
Also a fault message type can only be used with ABAP/Java Proxies. You cannot use it in a file/IDOC scenario. Also a fault message you cannot use Asynchronous communication.
Response Mapping is also just like your normal message mapping only. Once when you select the interface as Synchronous then you will automatically have your response in interface mapping. So it is having 2 message mappings one for request and one for response and one interface mapping.
Go through this weblog for some information on the request and response messages:
