Iam new to the ESB's and Apache Synapse. I have a simple REST API that takes a GET method and returns a simple json response. I tried to create a proxy with Apache Synapse.
The configuration is given below.
<proxy name="SampeJsonProxy">
<target>
<endpoint>
<address uri="http://localhost:8081/kafka/publish/hello" format="json" methods="GET"/>
</endpoint>
<inSequence>
<log level="full"/>
</inSequence>
<outSequence>
<send/>
</outSequence>
</target>
</proxy>
When I do a curl on the REST API I get response as
curl -v http://127.0.0.1:8081/kafka/publish/hello
* Trying 127.0.0.1...
* TCP_NODELAY set
* Connected to 127.0.0.1 (127.0.0.1) port 8081 (#0)
> GET /kafka/publish/hello HTTP/1.1
> Host: 127.0.0.1:8081
> User-Agent: curl/7.55.1
> Accept: */*

When I do a curl on the synapse server I get as below without response.
curl -v http://127.0.0.1:8280/kafka/publish/hello
* Trying 127.0.0.1...
* TCP_NODELAY set
* Connected to 127.0.0.1 (127.0.0.1) port 8280 (#0)

* Connection #0 to host 127.0.0.1 left intact
The log on synapse server is shown below.

I ran the configuration by editing the synapse_sample_150.xml and replacing content with above proxy and run it as synapse.bat -sample 150.
I don't understand why this is not working. Can someone help me understand the problem. I refered the second example in the here.
I found the problem. I was hitting at the wrong proxy.Giving a curl at http://127.0.0.1:8280/services/SampeJsonProxy
solves the gives the right output.
