Re: JMS to SOAP proxy: "HTTP/1.1 500 The endpoint reference (EPR) for the Operation not found"

Wed, 15 Oct 2008 21:29:18 -0700

Thank you very much for the info Ruwan. I used the property mediator approach to overcome a similar issue I faced when working with JMS to HTTP scenario with ESB. So based on your explanation, it seems that the header mediator is specifically designed to work with headers where as the property mediator can be used to set/remove any property in general. Please correct me if I am wrong here. Anyway I will sure have a look at the code. 

Thanks
Saliya

Saliya,

I guess what Paul suggested is the correct way of doing this, because even
though you set the transport header it will be overridden by the message
context action value. So there is a special header called Action in the
header mediator which will call the messageContext.setAction() with the
given value which is the correct approach.

Further there are some more special headers that the header mediator takes
care of and you could have a look at the header mediator source to find
them. (For example: To, ReplyTo, From)

Thanks,
Ruwan

Hi Joaquin,

Use the Property mediator to set the SOAP Action header. See the example
below.

<syn:property name="SOAPAction" value="echo" scope="transport"/>

Note: you have to set the scope to transport.

Saliya

I think what is happening is that Axis2 is expecting a SOAP Action for
the operation, and that isn't set, because that doesn't exist in JMS.

Please add a mediator:
  <header name="Action" value="urn:echo"/>

(Assuming that is the right action for your service).

Hi everybody,

I'm trying to forward a message received from a jms queue to a SOAP
service, but the message doesn't arrive to the SOAP service. Instead,
I get  a "HTTP/1.1 500 The endpoint reference (EPR) for the Operation
not found" error.

My synapse.xml looks like this:

<definitions xmlns="http://ws.apache.org/ns/synapse";>
  <proxy name="queueName" transports="jms">
      <target>
          <inSequence>
              <class name="path.to.DummyMediator" />
           </inSequence>
           <endpoint>
               <wsdl
uri="http://localhost:8081/axis2/services/EchoService?wsdl";
service="EchoService" port="EchoServiceHttpSoap11Endpoint"/>
           </endpoint>
      </target>
  </proxy>
</definitions>

Do you see any problems in my configuration? Please could you help me?

Thanks a lot!

Best regards,

--Joaquin
