Using javolution XML parser inside CXF
Hi all,
looking at the Javolution initiative www.javolution.org, I was really amazed
by the performances of their pull parser, so I wonder if it's possible to
use the Javolution parser, I think it could give CXF an excellent burst in
terms of performance.
Regards,
David

Hi David,
Woodstox is a StAX implementation (JSR 173). The Javalution APIs seemed to
have taken the StAX APIs and modified them to enable access to the character
data (i.e. char[]) instead of just Strings.
You can check out the woodstox website if you want to download it and play
with it: http://woodstox.codehaus.org
Cheers,
- Dan

Hi Dan,
thanks for the reply, I was looking at the cxf code, I couldn't find any
usage reference to the woodstox package. Any hint ?

Hi David,
I took a look at Javalution, but I'm a little bit skeptical. First, they
completely changed the StAX API in an incompatabile way which was
unnecessary. We can develop backward compatabile extensions to enable
efficient access of ints/longs/etc. Not that there is that much performance
value in that (at least from my limited tests). However, that limits our
ability to use it within CXF - we could develop something to enable it, but
that would be a lot of work and....
Second, I don't see any verification that their parser is actually faster
than Woodstox on their website. Tatu, the woodstox author, did some
benchmarking though. Woodstox is actually 20-25% faster than the Javalution
parser. :-)
Cheers,
- Dan
