So the question is: how does one register a new protocol in Java
so that you can create xmldb URLs and obtain a valid String when
doing getProtocol()?
URLStreamHandlerFactory is your friend and foe. It's your friend since
it allows you to add a custom protocol to Java, it's your foe since
only exactly ONE additional protocol per JVM is allowed. I think that
the double colon issue can be somehow solves, but this limitation is
quite hard to digest...
You could, instead, look into the Avalon Excalibur source resolver,
which is used by Cocoon. It gives you an abstraction that allows you to
do that. Also, with the XMLDBSource in the Cocoon XMLDB block, you've
effectively got a way of reading/writing to/from a XMLDB 'thing'.
Upayavira,
I'll take a look at that. I also found this:
Java 1.2 Unleashed: Content and Protocol Handlers
http://utenti.lycos.it/yanorel6/2/ch33.htm
which seems to provide a solution too.
Thanks,
Murray
