Deserialization Problem

[Stephen Harper <St...@gtnet.com>]

Hello All,

I'm generating code stubs using Axis and I have my own dynamically changing
Wsdl files which define their own complex types.  I get  the following
error:

PM org.apache.axis.client.Call invoke
SEVERE: Exception:
org.xml.sax.SAXException: Deserializing parameter 'account':  could not find
deserializer for type {http://www.w3.org/1999/XMLSchema}Account

I have seen similar errors to the one above in the forums.  A suggestion to
fix this is to create a mapping for the custom data type. Then do the
method-calls as normal. Suggestion is:

  ----------------------------------------------------
  Call call = (Call) service.createCall();
              QName collectionqn = new QName(DLM_NS,"collection");
              call.registerTypeMapping(Collection.class, collectionqn, new
                BeanSerializerFactory(Collection.class, collectionqn),
                  new
BeanDeserializerFactory(Collection.class,collectionqn));
  -----------------------------------------------------

However, before I run off building in the above, I was wondering if there is
any way to modify the WSDL to avoid having to deserialize objects?  The
reason I ask is because I am working on an existing project which already
works and is deployed and it does not have the above code.  The Wsdl files
it is currently using contains complex types so I was wondering if there are
options in the SOAP encoding that would prevent the above error from
occurring?

I have attached my Wsdl.

Thanks in advance,

Stephen
