ReplyTo header in Unified Endpoint configuration of WSO2 BPS

In a BPEL process, when there is an invoke to an external synchronus web service, and if you want to send the response of this service to a different endpoint (rather than sending back to the BPEL process), you can use Unified Endpoint configuration of WSO2 BPS 3.0.0 to set the WS:Addressing ReplyTo header as follows:

	<wsa:EndpointReference xmlns:wsa="http://www.w3.org/2005/08/addressing">
	<wsa:Address>http://localhost:9763/services/DebugService/</wsa:Address>
	<wsa:Metadata>
	<id>SInvokeEPR</id>
	<qos>
	<enableAddressing>
	<ReplyTo>http://localhost:8281/services/OtherServiceProxy</ReplyTo>
	</enableAddressing>
	</qos>
	</wsa:Metadata>
	</wsa:EndpointReference>

You can refer to this config file (locatd in registry or in the file system) as follows, inside the deploy.xml file:

	<invoke partnerLink="DebugPL">
	<service name="DebugService:DebugService" port="DebugServiceSOAP">
	<endpoint xmlns="http://wso2.org/bps/bpel/endpoint/config" endpointReference="debug.epr"/>
	</service>
	</invoke>

There are other use cases of UEP like adding QOS, Security etc. You can read more on that here.
