    Error while trying to consume Amazon Webservice

    Christian Pietsch Newbie

      G'day!
      I'm using Jboss 5 (Date 05/03/18) from CVS and trying to consume the amazon webservice defined at http://webservices.amazon.com/AWSECommerceService/2005-03-23/DE/AWSECommerceService.wsdl without any success. I'm always getting the following exception:


      Caused by: org.xml.sax.SAXException: Invalid element in com.amazon.webservices.AWSECommerceService.HelpResponse - OperationRequest
      at org.apache.axis.encoding.ser.BeanDeserializer.onStartChild(BeanDeserializer.java:407)


      Following the documentation at http://www.jboss.org/wiki/Wiki.jsp?page=JBossWS
      I've generated my java classes and jaxrpc-mapping.xml-file with patched jwsdp-1.5-jaxrcp-tools:

      wscompile -gen:client -f:documentliteral -mapping jaxrpc-mapping.xml d:\workspace/wsdl_client_gen/jwsdp_jaxrcp_config.xml


      I was able to deploy all files as EJB2.1-Session-Bean but when calling the endpoint from within my sessionbean I'll get the error from above. By the way: everything works as expected when consuming Google-Webservice, so I cannot be so wrong.

      server.log gives the following interesting information:

      ...
      2005-03-26 15:35:36,203 DEBUG [org.jboss.webservice.client.ServiceImpl] Service configuration:
      ...
      <#!-- Serializer/Deserializer not found, ignore type mapping
      <#typeMapping
      qname='ns1:>>>>>>>ItemSearchResponse>Items>Item>Offers>Offer>Seller>SellerFeedback>Feedback[1,unbounded]'
      xmlns:ns1='http://webservices.amazon.com/AWSECommerceService/2005-03-23'
      type='java:com.amazon.webservices.AWSECommerceService.Feedback[]'
      serializer='null'
      deserializer='null'
      encodingStyle=''>
      <#/typeMapping>
      -->
      ...

      Every complex-type-array is commented out as above. Maybe this is the reason for following error.

      Log goes on:

      I don't know anything more to try.

      Please tell me if you need more information.

          Have a look at the generated WSDD in ${jboss.server.data.dir}/wsdl. It will probably contain a number of commented out type mappings, which were derived from the jaxrpc-mapping.xml and other sources.

          At deployment time the type mapping could not be validated, so it was commented out.

          Also, the jaxrpc-mapping.xml seems to use ananomous names complex types in schema. That is, when the schema defines an element and gives its complex type definition as a child element rather than referencing it by name.

          The generated type-mappings in WSDD can be overridden in the ws4ee-deployment.xml descriptor, which you proabably have to use in your case.
