Actually, we *can* use JAXB-generated REST API Java types with GWT, since GWT compiler simply ignores annotations in Java sources during compilation to JavaScript. The only problem I see is REST API Java types using stuff like javax.xml.datatype.XMLGregorianCalendar - we'd have to emulate it in GWT (shouldn't be an issue). Other than that, I'd recommend using JAXB-generated REST API Java types, as they always match current REST API schema (api.xsd). As for the marshalling layer, we can't use JAXB (REST API Java SDK) with GWT, but we can still write deferred binding generator to generate mappers for XML <--> Rest API Java type conversion. > > if you not using JAXB, you should make sure calling variables in the classes that will be marshalled to XML > > as they are defined in the api schema and not using Java naming convention (as XJC does), Yeah, with XML representation we would have to do this ourselves. On the other hand, things would be much simpler if REST API supported JSON, which is something we should consider (wait for JSON support? work with XML?)
