Hi, My service accepts both XML and JSON representations. Obviously the business logic should be implemented once, so I need to pick a canonical representation. My options seem to be:
1. XML There are great tools for working with XML. I'd update the business layer objects using either XPath or SAX events. JSON representations would be converted into XML for processing. 2. POJO Deserialize representation into POJOs, directly from JSON or XML as appropriate. This avoids working with XML directly, but requires an extra data model (the legacy business layer uses POJOs annotated for Hibernate, but I want to decouple the REST layer from the business layer, so I'd have to duplicate the data model to some extent) I'd love to hear about what has worked and what hasn't worked from those who have gone before. Best regards Richard Hoberman
