TCP receive message to different port than sent on

[Gary Russell]

When you use the standard correlation id header (correlationId) you can just eliminate the correlation strategy from the aggregator - it will use that header by default.

That worked.

From the logs, I can see the messages being correlated, and the transformer outputting the message that contains the credit report. But for some reason, it doesn't get sent to the client-side tcp-inbound adapter.

This config:

<int:bridge
		order="1"
		input-channel="finalRequest"
		output-channel="toAggregator"/>
	
 	<int-ip:tcp-inbound-channel-adapter
 		id="fromServerSide"
 		channel="fromTransformer"
 		connection-factory="requestCF"/>

	<int:channel
		id="toAggregator"
		datatype="java.lang.String"/>
		
	<int:channel
		id="toTransformer"/>
		
	<int:channel
		id="fromTransformer"/>
		
	<int:aggregator
		input-channel="toAggregator"
		output-channel="toTransformer"
		release-strategy-expression="size() == 2"/>

	<int:transformer
		input-channel="toTransformer"
		output-channel="fromTransformer"
		expression="payload.get(1)"/>

results in this error:

[02-13-2013 14:11:55,507] ERROR TcpNetConnection:155 Exception sending meeeage: [Payload=[B@1445748][Headers={timestamp=1360782715460, id=862e2275-103e-4453-8ad2-345348896316, ip_tcp_remotePort=3411, ip_address=10.127.211.92, ip_hostname=VMCAP2ISDEVMED, ip_connectionId=VMCAP2ISDEVMED:3411:c8eff8bc-fb84-4e86-951b-90b712078091}]
org.springframework.integration.MessageDeliveryException: Dispatcher has no subscribers for channel fromTransformer.

Doesn't this config make the tcp-inbound-channel-adapter a subscriber to the fromTransformer channel?

[thisisCP]

I figured it out.

I forgot to add the default-reply-channel to my gateway.

I'm now able to send a request and get a response back.

Thanks for the help.

Cool!

Glad to help.
