Hi!
I'm new in using this Castor stuff and I'm currently using it
with the VAJ environment. Yet, I'm having a problem if in
Marshalling and Unmarshalling my xml files when I am pointing
my dtd to the SYSTEM instead of PUBLIC. What I meant is, VAJ
will give me a FileNotNotFoundException for the mapping.dtd.
Is anyone has encountered this type of problem before? I have
the dtd file in the resources directory of my VAJ project and
still I got this exception. Need your suggestions...
Thanks.
