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.
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.
