Question

Trying to get past a class cast exception here:

FooClass fooClass = (FooClass ) unmarshaller.unmarshal(inputStream); 

throws this exception:

java.lang.ClassCastException: javax.xml.bind.JAXBElement 

I don’t understand this – as the class was generated by the xjc.bat tool – and the classes it generated I have not altered at all – so there should be no casting problems here – the unmarshaller should really be giving me back a class that CAN be cast to FooClass.

Any ideas as to what I am doing wrong?

Answer 1

Does FooClass have the XmlRootElement annotation? If not, try:

Source source = new StreamSource(inputStream); JAXBElement<FooClass> root = unmarshaller.unmarshal(source, FooClass.class); FooClass foo = root.getValue(); 

That’s based on the Unofficial JAXB Guide.
