Is a ServerSocket Producer possible

[Andy Bailey <ha...@gmail.com>]

Hi

Im trying to do the following


from("timer:gps")
		.routeId("gps")
	
.setBody().constant("$GPGGA,123519,4807.038,N,01131.000,E,1,08,0.9,545.4,M,46.9,M,,*47")
		.log("${body}")
		.to("netty4:tcp://0.0.0.0:9999")
		;

The idea is to be able to do "nc localhost 9999" and see a stream of
messages 1 per second

However this gives
java.net.ConnectException: Cannot connect to 0.0.0.0:9999
	at
org.apache.camel.component.netty4.NettyProducer.openChannel(NettyProducer.java:421)
	at
org.apache.camel.component.netty4.NettyProducer$NettyProducerPoolableObjectFactory.makeObject(NettyProducer.java:486)

...
.to("netty4:tcp://localhost:9999")
;
also tries to make a socket connection to localhost as I would expect, is
there an option to create a server socket?

Ive also tried 
....
.to("netty4:tcp://:9999")
;

But that gives 
java.lang.IllegalArgumentException: hostname can't be null
	at java.net.InetSocketAddress.checkHost(InetSocketAddress.java:149)
	at java.net.InetSocketAddress.<init>(InetSocketAddress.java:216)
	at
org.apache.camel.component.netty4.NettyProducer.openConnection(NettyProducer.java:356)


However they always appear to create a Socket rather than a ServerSocket.

Is there a way with netty or mina to create the ServerSocket.

I have tried to use a consumer with sync=true however the trigger for the
sending of the message is not an incoming message so that doesnt appear to
work. Or is there an option I need to add to not wait for an incoming
message. Although a solution like that would complicate the logic of sending
the messages.

 
Please tell me if what I require can be done in camel out of the box, or do
I need to write a custom component?
