MULE ESB - simple jaxws client don't work … -

Hi guys first of all I want you to see my wsdl file it's DHL24 api I want learn a bit on this and use simple example here is the link https://dhl24.com.pl/webapi.html

I want to use getVersion as you can see we don't need to provide any data to this only in response we have getVersionResult - STRING

First of all I created package generated from apache CTX using simple project here is POM:

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

            </executions>
        </plugin>
    </plugins>
</build>

All is fine here I have package and classes so I start to create second project (as dependency I added this package - this works fine)

Now I want to create simple flow:

<flow name="getVersion" doc:name="getVersion">
    <http:inbound-endpoint exchange-pattern="request-response" host="localhost" port="8088" path="getVersion" doc:name="HTTP"/>

<logger doc:name="getVersion" message="Test Before" level="ERROR"/>
<cxf:jaxws-client operation="getVersion" clientClass="pl.test.integration.dhl.ws.client.DHL24WebapiService" port="DHL24WebapiPort" enableMuleSoapHeaders="true" doc:name="SOAP">
</cxf:jaxws-client>

<logger doc:name="getVersion" message="Test after" level="ERROR"/>
</flow>

Nothing big but when I post to this I have:

ERROR 2014-06-28 20:36:10,289 [[gaspoldhlservice].connector.http.mule.default.receiver.02] org.mule.api.processor.LoggerMessageProcessor: Test Before ERROR 2014-06-28 20:36:10,291 [[gaspoldhlservice].connector.http.mule.default.receiver.02] org.mule.exception.DefaultMessagingExceptionStrategy: **************************************************************************** Message : wrong number of arguments.

I was searching a bit in google and found something like this. I add after inbound:

<object-to-byte-array-transformer />

And I had other error:

ERROR 2014-06-28 20:45:18,149 [[gaspoldhlservice].connector.http.mule.default.receiver.02] org.mule.api.processor.LoggerMessageProcessor: Test Before ERROR 2014-06-28 20:45:18,151 [[gaspoldhlservice].connector.http.mule.default.receiver.02] org.mule.exception.DefaultMessagingExceptionStrategy: **************************************************************************** Message : wrong number of arguments.

I need a little bit push here its very simple method and I cant handle it right ...

AFTER EDIT:

Changed to your flow with:

<flow name="getVersion" doc:name="getVersion">
   <http:inbound-endpoint exchange-pattern="request-response" host="localhost" port="8088" path="getVersion" doc:name="HTTP"/>


<cxf:jaxws-client operation="getVersion" serviceClass="pl.test.integration.dhl.ws.client.DHL24WebapiService" port="DHL24WebapiPort" enableMuleSoapHeaders="true" doc:name="SOAP">
</cxf:jaxws-client>

<http:outbound-endpoint exchange-pattern="request-response"  address="http://localhost:8088/consumeTest" doc:name="HTTP" method="POST"/>

</flow>

<flow name="consumeTest" doc:name="consumeTest">
    <http:inbound-endpoint exchange-pattern="request-response" host="localhost" port="8088" path="consumeTest" doc:name="HTTP"/>
    <logger doc:name="getVersion" message="Test AFTER" level="ERROR"/>
</flow>

Answer is

No such operation: getVersion. Failed to route event via endpoint: org.mule.module.cxf.CxfOutboundMessageProcessor. Message payload is of type: ContentLengthInputStream

When I use clientClass instead of serviceClass:

wrong number of arguments. Failed to route event via endpoint: org.mule.module.cxf.CxfOutboundMessageProcessor. Message payload is of type: ContentLengthInputStream

回答1:

You need to put an outbound endpoint after cxf:jaxws-client like <http:outbound-endpoint exchange-pattern="request-response" address="Your external webservice path that you are tying to consume " doc:name="HTTP" method="POST"/> to post the value to the external webservice .. for example If your external webservice is at http://localhost:8086/mainData?wsdl then you need to put

<http:outbound-endpoint exchange-pattern="request-response" address="http://localhost:8086/mainData" doc:name="HTTP" method="POST"/> ................ and one more thing ... could you plase change <cxf:jaxws-client operation="getVersion" clientClass="pl.execon.integration.dhl.ws.client.DHL24WebapiService" port="DHL24WebapiPort" enableMuleSoapHeaders="true" doc:name="SOAP"> to

`<cxf:jaxws-client operation="getVersion" serviceClass="pl.execon.integration.dhl.ws.client.DHL24WebapiService" port="DHL24WebapiPort" enableMuleSoapHeaders="true" doc:name="SOAP">`  in your flow and try ...

So the final flow would be something like :-

 <flow name="getVersion" doc:name="getVersion">
        <http:inbound-endpoint exchange-pattern="request-response" host="localhost" port="8088" path="getVersion" doc:name="HTTP"/>


    <cxf:jaxws-client operation="getVersion" serviceClass="pl.execon.integration.dhl.ws.client.DHL24WebapiService" port="DHL24WebapiPort" enableMuleSoapHeaders="true" doc:name="SOAP">
    </cxf:jaxws-client>

    <http:outbound-endpoint exchange-pattern="request-response"  address="Your external webservice path that you are tying to consume " doc:name="HTTP" method="POST"/>
    </flow>
