How to Integrate RESTful service in the WSO2 ESB

I am trying to create an integration layer through the WSO2 ESB (RESTful API Service Integration).

Endpoint - http://www.thomas-bayer.com/

Context - /sqlrest

and

URI-template - /CUSTOMER/3

( API Endpoint - www.thomas-bayer.com/sqlrest/CUSTOMER/3 )

After everything when I'm trying to invoke the api request with ( http://localhost:8280:/sqlrest/CUSTOMER/3 )

I'm getting the response as full HTML with 404 error code rather than the XML Data.

you can use this API in WSO2 ESB:

<?xml version="1.0" encoding="UTF-8"?>
<api xmlns="http://ws.apache.org/ns/synapse"
     name="sqlrestAPI"
     context="/sqlrest">
   <resource methods="GET" protocol="http" uri-template="/CUSTOMER/{id}">
      <inSequence>
         <log level="full"/>
         <send>
            <endpoint>
               <http method="GET"
                     uri-template="http://www.thomas-bayer.com/sqlrest/CUSTOMER/{uri.var.id}"/>
            </endpoint>
         </send>
      </inSequence>
      <outSequence>
         <send/>
      </outSequence>
      <faultSequence/>
   </resource>
</api>

And call it with (OFFSET = 3 in my case):

curl -v http://localhost:8283/sqlrest/CUSTOMER/3

The response:

* About to connect() to localhost port 8283 (#0)
*   Trying 127.0.0.1...
* connected
* Connected to localhost (127.0.0.1) port 8283 (#0)

The context you provide does not need to be anything from the actual endpoint URL.

For example, you can define context as myapi. Then you have 2 options.

Option 1:

Configure endpoint as http://www.thomas-bayer.com/

Then you can call your API as http://localhost:8280/myapi/sqlrest/CUSTOMER/3

Option 2:

Configure endpoint as http://www.thomas-bayer.com/sqlrest/

Then you can call your API as http://localhost:8280/myapi/CUSTOMER/3
