Hi Tobias,
Most importantly: thanks for taking the time to reply :-)
I have 2 remaining questions:
1/ It seems (to me, at least) unefficient to have to do this at every
time you get a session, no? (as this is code that is passed every time
you get a session) Is there a way to "init" a session once and for all
so that every next call to it can assume this work is done instead of
having to check every other time it is done?
2/ Why do you explicitely (again) do the
"s.setNamespacePrefix("myapp", "http://your.com/ns/1";);" as you not
only registered the NS, but also provide the NS (myapp) in your call
on the next line: "s.getRootNode().getNode("myapp:someNode");"
Is it necessary?
Thanks in advance,
Wolf

namespaces are fully supported by jackrabbit since 1.0. and the
registration works exactly as specified in jsr170 (which is a bit
troublesome).
in your application you probably have a 'getRepositorySession' call,
and there i would setup/check the namespaces for your application, eg:
1. check if your namespace is already registered
2. if not, do so.
3. setup the namespace mapping for your session and application.
example:
try {
s.getNamespaceURI("http://your.com/ns/1";);
} catch (RepositoryException e) {
// register namespace
s.getWorkspace().getNamespaceRegistry().registerNamespace(
"myapp", "http://your.com/ns/1";);
}
s.setNamespacePrefix("myapp", "http://your.com/ns/1";);
[....]
s.getRootNode().getNode("myapp:someNode");
regards, toby
