Have you looked at Spring Integration samples?
You can get more info here: http://blog.springsource.com/2010/09...ation-samples/

There is a sample called multipart-http which is very close to what you are looking for.

Of cause, I did, especially on multipart-http.

The example uses inbound channel adapter. Is it possible to implement the same by HttpRequestHandlingMessagingGateway
or HttpRequestHandlingController ?

[oleg.zhurakousky]

All I am saying is substitute adapters with gateways. Have you tried it?
I'll make an additional example for it, but you don't have to wait. Just give it a shot.

I just posted a new sample which is a simple echo service which uses both inbound and outbound HTTP gateways
http://git.springsource.org/spring-i...ter/basic/http

Let me know if that helps

I did not found org.springframework.integration.samples.http.DemoH ttpClient
Than I ran the sample via mvn jetty:run, made the call via browser and got following. Looks like it works (more or less) but how to set correct properties in the request (Content-Type: charset=UTF-8)?

Sorry its org.springframework.integration.samples.http.HttpC lientDemo. I just fixed the readme.
And no, it will not work from the browser. You must invoke it through the client which is HTTP Outboud Gateway.
