Subject Re: ESB Performance Testing - Round 6
Date Wed, 29 Aug 2012 16:48:12 GMT

For what may be worth it, Camel now supports the VTD-XML library which
is a very fast and efficient XPath engine.

Though the camel-vtdxml component is hosted at Camel Extra due GPL
licensing of the VTD-XML library itself.

It works well for processing/splitting big files etc, where the xpath
and xquery can't cope so well (xquery using saxon).
I am not sure if any of the ESB's use that for xpath/xquery. But with
Camel we can now do that as well.

Installing it in OSGi I have not done. Hopefully installing the JAR
using wrap would be sufficient.
