Users - Problem with deserializing SOAP response message

Anna Schietz
hi,

I want to make a list of all categories of a catalog available in a spring
application. I couldn't figure out what all the RMI stuff is about so I
decided to use SOAP ;-)

I *finally* managed to call the service but now I get an error concerning
the responsemessage. The error was already reportetd elsewhere (e.g.
http://www.codecomments.com/archive420-2005-7-539685.html)... is this an
OfBiz bug? Is there nothing I can do about it?


*********************************************************
My test service (I used an existing service to minimze the amount of
mistakes I could make ;-):

<service name="getVariantCombinations" engine="java"
location="org.ofbiz.product.feature.ProductFeatureServices" export="true"
auth="false" invoke="getVariantCombinations">
                <description>....</description>
                <attribute type="String" mode="IN" name="productId" optional="false"/>
                <attribute type="List" mode="OUT" name="featureCombinations"
optional="false"/>
        </service>

    <service name="remoteGetVariantCombinations" engine="soap" export="true"
location="http://localhost:8080/webtools/control/SOAPService"
invoke="getVariantCombinations" auth="false">
        <description>Customer specific Price for defined
Product/Customer</description>
        <!--namespace>http://localhost:8080/</namespace-->
        <namespace>http://www.w3.org/2001/XMLSchema</namespace>
       
<!--namespace>http://schemas.xmlsoap.org/soap/encoding/</namespace-->
        <attribute type="String" mode="IN" name="productId"
optional="false"/>
                <attribute type="List" mode="OUT" name="featureCombinations"
optional="false"/>
     </service>

*********************************************************
And this is how I call it:

  String urlString="http://localhost:8080/webtools/control/SOAPService/";
  Call call = new Call();
 
call.setFullTargetObjectURI("http://localhost:8080/webtools/control/SOAPService/remoteGetVariantCombinations");
  call.setMethodName("remoteGetVariantCombinations");
  call.setEncodingStyleURI(Constants.NS_URI_SOAP_ENC);
  //call.setEncodingStyleURI(Constants.NS_URI_LITERAL_XML);

  Vector params = new Vector();
  //params.addElement(new Parameter("login.username", String.class, "admin",
null));
  //params.addElement(new Parameter("login.password", String.class, "ofbiz",
null));
  params.addElement(new Parameter("productId", String.class,productId,
null));

 //adding the parameter(s) to the Call object
  call.setParams(params);

 //invoke the soap method
  Response res = call.invoke(new URL(urlString), "");




*********************************************************
And here is the nice stacktrace:
