reader);

} catch (IOException e) {
e.printStackTrace();
}catch (ValidationException e) {
e.printStackTrace();
}catch(MarshalException e){

}
}
public <T> void writeObject(T obj, String toXML) {
try {
Writer writer = new FileWriter(toXML);
if (manager.getContext() == null) {
Marshaller.marshal(obj, writer);
return;
} else {
Marshaller marshaller =
manager.getContext().createMarshaller();
marshaller.setWriter(writer);
marshaller.marshal(obj);
// Marshaller.marshal(order, writer);
}
} catch (IOException e) {
e.printStackTrace();
}catch (ValidationException e) {
e.printStackTrace();
}catch(MarshalException e){
e.printStackTrace();
}
}
manager is a singleton which holds to the context.
Thanks for your quick response, please let me know if you need more
information to reproduce this.
