Client from Amazon Webservices

bogsolomon Nov 2, 2005 1:29 PM

I am using Jboss 4.0.2(tried 4.0.3 also) with the JbossWS package. I am trying to create a client that would connect to the Amazon webservice. For that I have obtained the wsdl, used wscompile to generate the classes and the mapping. I have then created a web.xml, jboss-web.xml, a small jsp page and a class that creates the service and the port and then sends arequest. Everything deploys but when I get the answer I get the following error

org.xml.sax.SAXException: Invalid element in amazon.ws.ItemSearchResponse - OperationRequest

my jaxrpc-mapping-client.xml contains the OperationRequest in ItemSearchResponse

<java-type>amazon.ws.ItemSearchResponse</java-type>
<anonymous-type-qname>http://webservices.amazon.com/AWSECommerceService/2005-10-05:&gt;ItemSearchResponse</anonymous-type-qname>

<variable-mapping>
<java-variable-name>items</java-variable-name>
<xml-element-name>Items</xml-element-name>
</variable-mapping>
</java-xml-type-mapping>

and

<java-type>amazon.ws.OperationRequest</java-type>

From what I have read on the forums the problem might be with the way they are declared in the WSDL as annonymous. However I am not sure how to fix this.

Managed to solve that problem by mapping each of the properties in a ws4ee-deployment file. I can contact the web service but it is not receiving my parameters. I have found this http://www.jboss.org/index.html?module=bb&op=viewtopic&t=60455 as a solution to the problem. However it is not updating the SOAP message with the appropriate namespaces.

 <typeMapping
 qname='ns2:ItemSearch' xmlns:ns2='http://webservices.amazon.com/AWSECommerceService/2005-10-05'
 type='java:webservices.amazon.com.ItemSearch'
 serializer='org.jboss.webservice.encoding.ser.MetaDataBeanSerializerFactory'
 deserializer='org.jboss.webservice.encoding.ser.MetaDataBeanDeserializerFactory'
 encodingStyle=''>
 <typeDesc>
 <elementDesc fieldName='SubscriptionId' xmlName='ns2:SubscriptionId'/>
 <elementDesc fieldName='Request' xmlName='ns2:Request'/>
 </typeDesc>
 </typeMapping>

still results in

<soapenv:Body>
 <ns1:ItemSearch xmlns:ns1="http://webservices.amazon.com/AWSECommerceService/2005-10-05">
 <subscriptionId>xxxxxxxx</subscriptionId>
 <AWSAccessKeyId>xxxxxxxxx</AWSAccessKeyId>
 <associateTag/>
 <XMLEscaping>Single</XMLEscaping>
 <validate>false</validate>
 <shared xsi:nil="1"/>
 <request>
 <actor xsi:nil="1"/>

Support elementFormDefault=qualified should be fixed
