WSO2 ESB - REST API - Response Does Not Come - wso2-esb

Question

I have exposed a REST service using <api> in wso2 esb. But the response does not come. REST service is written in Apache Wink.
API
<api name="API_2" context="/hello" hostname="localhost" port="8080">
<resource url-mapping="/name" methods="GET">
<inSequence>
<log level="full"/>
<property name="messageType" value="text/plain" scope="transport" type="STRING"/>
<send>
<endpoint>
<address uri="http://localhost:8080/HelloService/rest/test/hello"/>
</endpoint>
</send>
</inSequence>
<outSequence>
<log level="full"/>
<send/>
</outSequence>
</resource>
</api>
esb log
[2013-12-11 12:28:24,643] INFO - API Initializing API: API_2
[2013-12-11 12:28:35,467] INFO - LogMediator To: /hello/name, MessageID: urn:uuid:52d2ddf1-301e-42e0-ac9d-ac4a57ac8c72, Direction: request

I think your endpoint address is wrong , look like you have repeat hello twice. since you have hello in proxy name also which will append to URL.
try <address uri="http://localhost:8080/HelloService/rest/test"/>
Also You can verify your backend works by calling "uri + url-mapping" in separate browser
I have shown sample API works for me below, you should have called your API as below and log will print as below.
URL to call: http://localhost:8280/TestAPI/customerservice/customers/123
INFO - LogMediator To: /TestAPI/customerservice/customers/123
<api xmlns="http://ws.apache.org/ns/synapse" name="TestAPI" context="/TestAPI">
<resource methods="GET" url-mapping="/customerservice/customers/123">
<inSequence>
<log/>
<send>
<endpoint>
<address uri="http://localhost:9764/jaxrs_basic/services/customers"/>
</endpoint>
</send>
</inSequence>
<outSequence>
<log/>
<send/>
</outSequence>
</resource>
</api>
