Is there a way to transform a JAXB generated object to another JAXB object using an XSLT template file. The two objects are generated by two different JAXB bindings.
I know that I can marshall the object to strings and then using a XSLT processor to transform it to the other format. After that unmarshall it to the other JAXB object.
The question is if this is possible in to do in JAXB.
I don't think its possible without any intermediate serialization or dom tree construction, but serializing to a string would be the worst option imho. The best option would probably to marshal to a TransformerHandler which does the xsl transformation and builds a dom tree. This tree can then be unmarshalled again. Here is some (untested) sample code showing how this could work:
Source xsl = ...
SAXTransformerFactory factory = (SAXTransformerFactory) TransformerFactory.newInstance();
TransformerHandler handler = factory.newTransformerHandler(xsl);
DOMResult result = new DOMResult();
handler.setResult(result);
marshaller.marshal(inputObject, handler);
transformedObject = unmarshaller.unmarshal(result.getNode());
No, it is not possible. JAXB converts Java to XML or XML to Java. If you have XML, then use XSLT to transform the document. If you have a Java object, then use Java to transform an object. There is no intermediary format.
