Hi Werner, Thanks for your response. Please see my comments inlined below:> >
if I were you, I would stop worrying about Castor's use of reflection,> as this
is a one-time only penalty (as startup) if used correctly. One-time penalty of
reflection for building the class descriptor is ok, but using reflection for
every get/set of a field while marshalling / unmarshalling seems slow, since
there will be millions of get/set method calls.What is the correct way to avoid
reflection during marshalling / unmarshalling ? > Let me ask you a few
questions, though:> > a) Will you be using a mapping file ?> b) Have you
considered using the XML code generator to generate domain> classes (and
descriptor classes) from your XML schema(s) ? I'm starting with a set of Java
classes which are already in use by applications and cannot be changed. These
Java classesneed to be persisted in an XML store.I would prefer not to use a
mapping file unless the default Castor Java->XML mapping needs to be changed
for some class.> c) Have you already looked at the documentation of the>
XMLClassDescriptorResolver ? Yes but it doesnt seem to provide a way to avoid
using reflectionduring marshalling / unmarshalling.> d) Are you using Spring,
and would you like to integrate Castor with> Spring ?
No.
