Hi All,

What I want to do is return an ArrayList of HashMaps from a
web service.

This is an EJB (stateless) that I can´t really change so I can´t change the return type to Object[] etc

I am using:

OS: windows 2000
Server: weblogic 7.0 service pack 5

The error I get is:

java.rmi.RemoteException: web service invoke failed; nested exception is:
javax.xml.soap.SOAPException: failed to deserialize xml:weblogic.xml.schema.binding.DeserializationException: mapping lookup failure. type=['http://www.w3.org/2001/XMLSchema']:anyType schema context=TypedSchemaContext{javaType=javax.xml.soap.SOAPElement}

javax.xml.soap.SOAPException: failed to deserialize xml:weblogic.xml.schema.binding.DeserializationException: mapping lookup failure. type=['http://www.w3.org/2001/XMLSchema']:anyType schema context=TypedSchemaContext{javaType=javax.xml.soap.SOAPElement}

The relevant part of the web-services.xml is:

  <web-service targetNamespace="http://www.indra.com/webservices/Callejero" uri="/Callejero" style="rpc" name="Callejero" protocol="http">
    <types>
    <xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema"
  xmlns:stns="java:language_builtins.util"

                     type="xsd:string">
        </xsd:element>
      </xsd:sequence>
   </xsd:complexType>
</xsd:schema>

</types>


My class to do the serialization/deserialization:

public class HashMap extends AbstractCodec
{
  public HashMap()
  {}

public void serialize(Object obj,
                        XMLName name,
                        XMLOutputStream writer,
                        SerializationContext context)
    throws SerializationException
{
try {
    out("serialize");
    out("XMLNAME: " + name);

      java.util.HashMap map = (java.util.HashMap)obj;

      //outer start element
      writer.add(ElementFactory.createStartElement(name));

      Iterator itKeys = map.keySet().iterator();

      Object objKey = null;
      Object objValor = null;

      while(itKeys.hasNext())
      {
        objKey = itKeys.next();
        objValor = map.get(objKey);

        out("KEY: " + objKey);
        out("VALOR: " + objValor);

        //employee name element
        writer.add(ElementFactory.createStartElement("key"));
        writer.add(ElementFactory.createCharacterData(objKey.toString()));
        writer.add(ElementFactory.createEndElement("key"));

        //employee id element
        writer.add(ElementFactory.createStartElement("valor"));
        writer.add(ElementFactory.createCharacterData(objValor.toString()));
        writer.add(ElementFactory.createEndElement("valor"));
      }

      //outer end element
      writer.add(ElementFactory.createEndElement(name));

    } catch(XMLStreamException xse) {
      throw new SerializationException("stream error", xse);
    }
}

How I register my mapping in the client:

      Callejero_Impl impl = new Callejero_Impl(urlWSDL.toString());
      TypeMapping mapping = impl.getTypeMappingRegistry().getTypeMapping(SOAPConstants.URI_NS_SOAP_ENCODING);
      mapping.register(java.util.HashMap.class,new QName("java.util.HashMap"),new com.factoriaSoftware.soap.codecs.HashMap(),new com.factoriaSoftware.soap.codecs.HashMap());
      CallejeroPort port = impl.getCallejeroPort();
      port.setAplicacion("TSGF");
      //This should be a list of HashMaps but fails
      Object[] list = port.getProvinciasFromCP("0200");

If anyone has any ideas please reply and sorry for the long message .

I'm not sure, but i have used wsdl2java that is a tool from axis for generating clients to invoke a webservice.
I have used it in calling ws that returns complex objects.
It is not a difficult tool to use.

http://ws.apache.org/axis/java/user-guide.html and look for wsdl2java

I hope this will help.

I am getting same error.

The client works as standalone but does not work from WebLogic War file
