In my opinion, writing a pre-anything hook in Java is not viable because
of the overhead of starting the JVM. If that is not an issue for you,
then your next problem is that there are no Java API's that can
interrogate transactions, so you'd probably have to contribute that
support to JavaHL yourself. To do it today, you'd have to execute svnlook
from Java which would be pointless.
Note that I am one of the biggest consumers of JavaHL, so it is not like I
am against Java. I actually do some post-xxx hooks using Java. What I
did was I have a Java daemon process that is always running and monitoring
a folder. The hook script is just a shell script and it dumps info about
the commit/prop-change into a file in the folder. This way, the hook runs
fast as the Java processing is done in the background. It would be hard
to do the same from a pre-xxx hook.
I'd say you are better off trying to use Python or a shell script.
