Please advise on the WSDL

问题

I have created a WSDL to create a greeting service. Given below is the WSDL.

I am using thsi wsdl to create a generate and expose a web-service using the cxf:proxy-service in mule.

This is giving me errors.

Please review and help me undertand what is the problem with this WSDL.

Please help me if there is something wrong in my WSDL. It is not working when I use it in mule cxf:proxy-service.

FGiven below si the Mule Flow which is using this WSDL to expose service.

<flow name="WS_In">
    <http:inbound-endpoint address="http://localhost:8080/HelloService" exchange-pattern="request-response">
        <cxf:proxy-service  wsdlLocation="classpath:globalid3.wsdl" namespace="http://example.org/HelloService" service="ProxyService" />
    </http:inbound-endpoint>        
    <component>             
        <prototype-object class="com.example.ServiceProxy">                                                         
        </prototype-object>
    </component>        
    <echo-component></echo-component>
    <logger level="INFO"        />
</flow>

and the Error is :

org.mule.api.lifecycle.LifecycleException: Lifecycle Manager 'WS_In.stage1' phase 'start' does not support phase 'dispose'
at org.mule.lifecycle.AbstractLifecycleManager.invokePhase(AbstractLifecycleManager.java:156)

回答1:

There is a casing issue in your WSDL. Instead of:

  <wsdl:message name="greetingResponse">
    <wsdl:part type="tns:greeting" name="greetings"/>
  </wsdl:message>

you should have:

  <wsdl:message name="greetingResponse">
    <wsdl:part type="tns:Greeting" name="greetings"/>
  </wsdl:message>

With this fixed, the following produces a web service that works fine when called from SOAPui:

<flow name="WS_In">
    <http:inbound-endpoint address="http://localhost:8080/HelloService"
        exchange-pattern="request-response">
        <cxf:proxy-service wsdlLocation="classpath:globalid3.wsdl"
            namespace="http://example.org/HelloService" service="ProxyService" />
    </http:inbound-endpoint>
    <custom-processor class="com.example.ServiceProxy" />
</flow>

Message processor:

package com.example;

import javax.xml.namespace.QName;

import org.apache.commons.lang.StringEscapeUtils;
import org.mule.api.MuleEvent;
import org.mule.api.MuleException;
import org.mule.api.processor.MessageProcessor;

public class ServiceProxy implements MessageProcessor
{
    private final static QName SIMPLE_GREETING = new QName("http://example.org/HelloService",
        "simpleGreeting");

    public MuleEvent process(final MuleEvent event) throws MuleException
    {
        final QName operation = event.getFlowVariable("cxf_operation");

        if (operation.equals(SIMPLE_GREETING))
        {
            final String lastName = event.getMuleContext()
                .getExpressionLanguage()
                .evaluate("xpath('/lastName').text", event);

            final String responseXml = "<greetings><greet>Hi " + StringEscapeUtils.escapeXml(lastName)
                                       + "</greet></greetings>";

            event.getMessage().setPayload(responseXml);
            return event;
        }

        throw new UnsupportedOperationException(operation.getLocalPart() + " " + operation.getNamespaceURI()
                                                + " " + operation.getPrefix());
    }
}

There is one way to do this using cxf:jaxws-service, but you'll need to generate the service class. Take a look here on how to do this.

After that you can configure the service in a very simple way.

        <cxf:jaxws-service
            serviceClass="mypackage.webservices.MyServicePortType"
            validationEnabled="false">
        </cxf:jaxws-service>

The flow that is working is as below.

<flow name="WS_In">
    <http:inbound-endpoint address="http://localhost:8080/HelloService" exchange-pattern="request-response">
            <cxf:proxy-service  wsdlLocation="classpath:helloservice.wsdl" namespace="http://example.org/HelloService" service="ProxyService" />
        </http:inbound-endpoint>        
        <component>             
            <prototype-object class="com.example.ServiceProxy">     
            </prototype-object>
        </component>        
        <echo-component></echo-component>
        <logger level="INFO"        />
 </flow>

And the WSDL is

<?xml version='1.0' encoding='UTF-8'?>
<wsdl:definitions name="HelloService"
    targetNamespace="http://example.org/HelloService"
    xmlns:tns="http://example.org/HelloService"

      <wsdl:message name="shortRequest">
        <wsdl:part type="xsd:string" name="lastName"/>
      </wsdl:message>

      <wsdl:message name="fullRequest">
        <wsdl:part type="xsd:string" name="firstName"/>
        <wsdl:part type="xsd:string" name="lastName"/>
      </wsdl:message>

      <wsdl:message name="greetingResponse">
        <wsdl:part type="xsd:string" name="greetings"/>
      </wsdl:message>   


      <wsdl:portType name="HelloServicePortType">

        <wsdl:operation name="simpleGreeting">
          <wsdl:input message="tns:shortRequest" name="shortRequest" />
          <wsdl:output message="tns:greetingResponse" name="greetingResponse" />
        </wsdl:operation>

        <wsdl:operation name="fullGreeting">
          <wsdl:input message="tns:fullRequest" name="fullRequest" />
          <wsdl:output message="tns:greetingResponse"  name="greetingResponseFull" />
        </wsdl:operation>

      </wsdl:portType>


    <wsdl:binding name="HelloServiceSOAP" type="tns:HelloServicePortType">
        <soap:binding style="document" transport="http://schemas.xmlsoap.org/soap/http"/>

        <wsdl:operation name="simpleGreeting">
          <soap:operation soapAction=""  style="document" />
          <wsdl:input name="shortRequest">
            <soap:body use="literal"/>
          </wsdl:input>
          <wsdl:output name="greetingResponse">
            <soap:body use="literal"/>
          </wsdl:output>
        </wsdl:operation>

       <wsdl:operation name="fullGreeting">
          <soap:operation soapAction=""  style="document" />
          <wsdl:input name="fullRequest">
            <soap:body use="literal"/>
          </wsdl:input>
          <wsdl:output name="greetingResponseFull">
            <soap:body use="literal"/>
          </wsdl:output>
        </wsdl:operation>

      </wsdl:binding>

    <wsdl:service name="ProxyService">
        <wsdl:port binding="tns:HelloServiceSOAP" name="HelloServiceSOAPB">
            <soap:address location="http://localhost:8080/HelloService" />
        </wsdl:port>
    </wsdl:service>

</wsdl:definitions>

Thanks everyone for your help and support.
