Subject RE: <dtd> nested element with WebLogic 6.0
Date Wed, 24 Oct 2001 13:48:11 GMT

Well, now that you mention it, the SAX parser actually was one factor in
my decision to reference the DTD's locally for my <ejbjar> tasks. The
copy of weblogic.jar included with Bea WebLogic 6.0 contains an old SAX
parser, so if you are using jdom you can run into conflicts if you put
weblogic.jar on the CLASSPATH before jdom. As I understand it, the local
references aren't actually necessary. However, to paraphrase the Ant
User Manual, "The supported vendor-specific nested elements know the
location of the required DTDs within the vendor class hierarchy; this
means, however, that the vendor's class hierarchy must be available in
the classpath when Ant is started.". I thought that a  cleaner solution
would be to run Ant without requiring the vendor classes (a.k.a
weblogic.jar) in the classpath, and use a nested <dtd> element to
reference the files locally. Another argument for doing this is that
using a local DTD is much faster than loading the DTD across the net
(not to mention that if you are running ejbjar behind a firewall you may
not even be able to access the remote DTD). Don't know if I understood
the question you were asking correctly, however?

Curious:  Why are these local dtd references necessary for <ejbjar>?  Do
these messages originate in the SAX parser?  I poked around the source
without enlightenment.
