I've already let out a few primal screams over this one! I cannot find ANY good references for how to use the Axis type mapping features in the form of Serializers and Deserializers external to what automatically happens when calling a web service.
Before I began implementing my service as a web service, I was using JAXB to (un)marshal rather painlessly back and forth from XML to Java. I decided that I had to abandon JAXB since the Serialization/Deserialization process associated with SOAP encoding wanted REAL JavaBeans, of which JAXB objects are not! (I could rant about JAXB being included in the JWSDP for hours!). I realized upon initial pass of the Axis impl of the whole SOAP encoding Serialization/Deserialization framework that I was about to tread some deep water. And I really did not want to hand this stuff off to junior developers to write clients to (un)marshal this way since it appeared so NON-TRIVIAL. I put an indepth analysis of this Serialization/Deserialization stuff aside and opted for Castor XML binding since it would (un)marshal to REAL JavaBeans in a fairly trivial manner. However, I figured that if the WSDL2Java process was going to dump some Axis specific Serialization/Deserialization references at the bottom of all my JavaBeans (can I prevent this?), and require me to include all the Axis jars with my JavaBeans anyway, I should probably take another stab at this process. I think (with about 40% confidence) that I should serialize in the following manner: ... MyClass myObject = myService.getMyObject(); QName qName = new QName( "http://dto.domain.com";, "myRootElement" ); SerializationContext context = new SerializationContextImpl( new OutputStreamWriter( System.out ) ); /* // not sure if I need to do this or not ... TypeMappingRegistry registry = context.getTypeMappingRegistry(); TypeMapping typeMapping = (TypeMapping) registry.getTypeMapping( Constants.URI_LITERAL_ENC ); if ( typeMapping == null ) { typeMapping = (TypeMapping) registry.createTypeMapping(); registry.register( Constants.URI_LITERAL_ENC, typeMapping ); } typeMapping.register( MyClass.class, qName, new BeanSerializerFactory( MyClass.class, qName ), new BeanDeserializerFactory( MyClass.class, qName ) ); */ Serializer serializer = MyClass.getSerializer( "", MyClass.class, qName ); serializer.serialize( qName, null, myObject, context ); ... The last line throughs a NullPointerException. I have no idea what the org.xml.sax.Attributes are that this method expects or how to get them. Any references or ideas that anyone might have here would be greatly appreciated. If I can ever figure out what the heck is going on here I'm definitely going to write a paper on it from the dumb user perspective. - Lord knows we need it. All I see is questions about this stuff and no good answers. Cheers.
