axiom.soap.SOAPProcessingException: Transport level information does not match with SOAP Message namespace URI

This is a common exception [1]we see when invoke services hosted in axis2 based servers.
It occurs due to the namespace mismatch in the request. Check the service'e version and the request's version.
eg: SOAP 1.2 message with content type text/xml, we get this error. Correct the namespace in the request.

Synapse Handler

Synapse handler is similar to axis2 handler , that can be used in RESTAPIs to handle incoming request and the responses.

Sample handler ;

package test;

import org.apache.synapse.MessageContext;

import org.apache.synapse.rest.AbstractHandler;

public class TestSynapseHandler extends AbstractHandler {

@Override

public boolean handleRequest(MessageContext messageContext) {

String idKey = "idKey";

String idValue = "abc";

messageContext.setProperty(idKey, idValue);

return true;

}

@Override

public boolean handleResponse(MessageContext messageContext) {

// TODO Response handling

return true;

}

}

Handler has to be registered in the RESTAPI configuration.

Sample configuration;

<api xmlns="http://ws.apache.org/ns/synapse" name="calAPI" context="/cal">
   <resource methods="GET">
      <nSequence>
         <send>
            <endpoint>
               <address uri="http://localhost:9763/services/calservice"/>
            </endpoint>
         </send>
      </inSequence>
      <outSequence>
         <send>
            <endpoint>
               <default/>
            </endpoint>
         </send>
      </outSequence>
   </resource>
<handlers>
        < handler class="test.TestSynapseHandler"/>
   </handlers>
</api>
