Hello,
I am trying to marshall one of several classes created created by the xjc compiler from .xsd. Not sure why the object can't be marshalled???

<%
ObjectFactory objFactory = new ObjectFactory();
SoftwareType st = objFactory.createSoftwareType();
st.setName("java");
st.setVersion("1.4");
st.setComments("comments here");

JAXBContext jaxbcontext = JAXBContext.newInstance("sourceforge.psi.mzdata");
Marshaller marshaller = jaxbcontext.createMarshaller();
marshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, new Boolean(true));
marshaller.marshal(st,System.out);
%>


Here is the stack trace:
javax.xml.bind.MarshalException: the object parameter to marshal() is not marshallable

}

}


Thanks,Eric

I am not very sure of this but try changing the modifier for your variables from protected to private.

Also what happens if you set the completionTime variable.

Let me know if it works.
