Configuring HTTP endpoint with SOAP in Mule Flows

Question

I am trying to configure an existing SOAP web service in Mule using Mule Flows. I have an HTTP endpoint with request/response and a SOAP component, say Service A.

Simple SOAP flow I want to configure this setup for a simple flow to work. I have set my HTTP endpoint and the SOAP service. The flow file is shown below.

    <?xml version="1.0" encoding="UTF-8"?>

<mule xmlns="http://www.mulesoft.org/schema/mule/core" xmlns:http="http://www.mulesoft.org/schema/mule/http" xmlns:cxf="http://www.mulesoft.org/schema/mule/cxf" xmlns:doc="http://www.mulesoft.org/schema/mule/documentation" xmlns:spring="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" version="CE-3.2.1" xsi:schemaLocation="
http://www.mulesoft.org/schema/mule/http http://www.mulesoft.org/schema/mule/http/current/mule-http.xsd 
http://www.mulesoft.org/schema/mule/cxf http://www.mulesoft.org/schema/mule/cxf/current/mule-cxf.xsd 
http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd 
http://www.mulesoft.org/schema/mule/core http://www.mulesoft.org/schema/mule/core/current/mule.xsd ">
    <flow name="demoflowFlow1" doc:name="demoflowFlow1">
        <http:inbound-endpoint exchange-pattern="request-response" host="localhost" port="8081" doc:name="HTTP"/>
        <cxf:jaxws-service port="8082" serviceClass="com.myapp.serviceA.ServiceAImplService" doc:name="SOAP"/>
    </flow>
</mule>

This is not working. My service is a simple one and it takes in a string and returns a string.

@WebService(targetNamespace = "http://service.demo.myapp.com/", endpointInterface = "com.myapp.demo.service.IServiceA", portName = "ServiceAImplPort", serviceName = "ServiceAImplService")
public class ServiceAImpl implements IServiceA {
    public String hello(String user) {
        return "at service A: " + user;
    }
}

I am invoking my flow with the HTTP inbound URL http://localhost:8081/{I am not sure what goes here!} and getting:

<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
<soap:Body>
<soap:Fault>
<faultcode>soap:Server</faultcode>
<faultstring>No such operation: (HTTP GET PATH_INFO: /)</faultstring>
</soap:Fault>
</soap:Body>
</soap:Envelope>

The Mule flow is running as an application in Mule Studio, and the service is running as a SOAP web service from Springsource toolsuite.

What am I doing wrong?

</wsdl:definitions>

FYI, I can run the web service from SpringSource toolsuite without issues. Now, how do I invoke the web service from my HTTP inbound URL with a GET request? [I presume simple web services like these take GET requests.]

SOAP web services are accessed with POST not GET. In your case, have you considered using a simple-service pattern instead of a flow? mulesoft.org/documentation/display/MULE3USER/… — David Dossot
Actually, I am not too clear about consuming a SOAP web-service in a flow. Once I get this pat, I will move to a much more complex flow where there are parallel calls to multiple services and I will have to use choice routers while invoking some services too. So, I will have to use the flow pattern anyway. — r3st0r3
Have you managed to get it working? I am in a similar dilemma now. — Valentin Despa

I think you forgot the @WebMethod annotation at your method. This is basically what your error says: No operation.

Here is a very good example how you can do it.

@WebService(targetNamespace = "http://service.demo.myapp.com/", endpointInterface = "com.myapp.demo.service.IServiceA", portName = "ServiceAImplPort", serviceName = "ServiceAImplService")
public class ServiceAImpl implements IServiceA {
    @WebMethod
    @WebResult(name="result")
    public String hello(@WebParam(name="user")String user) {
        return "at service A: " + user;
    }
}
