non axis-specific way to do type mappings?

[__matthewHawthorne]

When writing a web service client, is there a way to set the type 
mappings using:
java.xml.rpc.Call or java.xml.rpc.Service

instead of using:
org.apache.axis.client.Call.registerTypeMapping(Class, QName, 
SerializerFactory, DeserializerFactory)

I've tried this:

  TypeMapping mapping = registry.createTypeMapping();

  mapping.register(clazz, qname,
    new BeanSerializerFactory(clazz, qname),
    new BeanDeserializerFactory(clazz, qname));
  // What to use for encoding here?
  registry.register("", mapping);
But it doesn't seem to have an effect.  I get the "no serializer" errors.

I've been able to get it to work in the first way that I mentioned, but 
I would like to keep my code non Axis-specific if possible.  Any ideas?

Thanks!
