External SOAP service issue

[moraleslos]

I'm trying to create a simple switchyard app where it invokes an external SOAP service (doc/lit) to get weather results given a zip code.  The public site and WSDL can be found here: http://wsf.cdyne.com/WeatherWS/Weather.asmx?WSDL

Now when I deploy this switchyard app, I get the folllowing error message:

org.switchyard.extensions.wsdl.WSDLReaderException: SWITCHYARD012801: Service operations on a WSDL interface must have exactly one parameter.

  at org.switchyard.extensions.wsdl.WSDLReader.getParts(WSDLReader.java:361)

  at org.switchyard.extensions.wsdl.WSDLReader.readWSDL(WSDLReader.java:101)

  at org.switchyard.extensions.wsdl.WSDLService.fromWSDL(WSDLService.java:100)

  at org.switchyard.extensions.wsdl.WSDLService.fromWSDL(WSDLService.java:83)

  at org.switchyard.deploy.internal.Deployment.loadServiceInterface(Deployment.java:413)

  ... 10 more

The WSDL looks correct to me and this is something I can't change obviously so how do I go about getting this to work?  Below is my switchyard xml:

    <sca:component name="Route">

      <camel:implementation.camel>

        <camel:xml path="route.xml"/>

      </camel:implementation.camel>

      <sca:service name="WeatherService">

        <sca:interface.java interface="net.test.weather.WeatherService"/>

      </sca:service>

      <sca:reference name="WeatherSoap">

        <sca:interface.wsdl interface="Weather.wsdl#wsdl.porttype(WeatherSoap)"/>

      </sca:reference>

    </sca:component>

    <sca:reference name="WeatherSoap" multiplicity="0..1" promote="Route/WeatherSoap">

      <sca:interface.wsdl interface="Weather.wsdl#wsdl.porttype(WeatherSoap)"/>

      <soap:binding.soap name="WeatherExternalSoap">

        <soap:messageComposer unwrapped="true"/>

        <soap:wsdl>Weather.wsdl</soap:wsdl>

        <soap:wsdlPort>WeatherSoap12</soap:wsdlPort>

      </soap:binding.soap>

    </sca:reference>

    <sca:service name="WeatherService" promote="Route/WeatherService">

      <sca:interface.java interface=net.test.weather.WeatherService"/>

      <resteasy:binding.rest name="WeatherServiceRest">

        <resteasy:interfaces>net.test.weather.WeatherServiceRest</resteasy:interfaces>

        <resteasy:contextPath>weather-soap</resteasy:contextPath>

      </resteasy:binding.rest>

    </sca:service>

Below is my route:

<routes xmlns="http://camel.apache.org/schema/spring">

  <route>

    <from uri="switchyard://WeatherService"/>

    <log message="WeatherService - message received: ${body}"/>

    <to uri="switchyard://WeatherExternalSoap"/>

  </route>

</routes>

Any ideas?  Thanks in advanced.

Hi Los Morales,

It seems like a bug. Would you mind opening a JIRA for it. The problem seems to be when SwitchYard parses the WSDL.

[jorgemoralespou_2]

The problem is mainly due to the fact that WSDLService and WSDLReader reads the whole WSDL not taking into account if the message/part is belonging to the portType defined. In your wsdl you have operations that do not comply with SwitchYard requirements that are defined in a different portType than the used.

A workaround can be to use a reduced version of the wsdl for internal contract definition, while using the public for the binding. Detailed steps:

1- Create a copy of the wsdl

2- Remove everything related to the portType WeatherHttpPost and WeatherHttpGet. All the messages and parts.

3- Use this wsdl for the contracts definition (composite service contract and component service contract).

4- Use the original wsdl (the real one) for the binding.

In summary, you'll have 2 wsdls, the weather.wsdl and the weather-sy.wsdl (reduced version).

Hope it helps.

PS: But do not forget to open the JIRA.

This has been discussed a long time ago here.

Hi,

Thanks for responding.  I trimmed the wsdl to make it work.  Now when I invoke the SOAP service I'm getting this error back: 

org.xml.sax.SAXParseException: Content is not allowed in prolog.

This looks to happen when a response comes back from the SOAP service and it can't understand the response.  Am I supposed to create a composer or processor to marshal the response into a pojo?

It seems to have invalid character (BOM or something) in its XML payload. Please make sure the external Web service returns valid XML response.
