Re: XPath and Drools routing with SXC?
Were you thinking of integrating it with EIP routing? That could possibly be done. On 3/17/07, Dan Diephouse <[EMAIL PROTECTED]> wrote: Hi All, I think I wrote something which may be of use to ServiceMix, but unfortunately I don't have time to integrate it myself - so I'm going to throw it out there for everyone :-) I started a project called SXC - simple xml compiler - which creates optimized xml parsers for various things. There is one for JAXB. But, the one of probably the most interest to this crew is the XPath frontend. SXC can build a streaming xpath parser for you (at runtime). This means you can listen for XPath events as you scan over the document. This allows for very efficient XPath based routing. In my initial performance test it was about 100x faster than Jaxen for locating nodes (although thats a very rough benchmark, real numbers may vary!) We also integrated it with Drools so you can write XPath expressions right in your rules. Check out these links for more information: http://sxc.codehaus.org http://sxc.codehaus.org/XPath http://sxc.codehaus.org/Drools The one caveat is that we support only a limited subset of XPath expressions at the moment. But if you wanted to hack SXC, its easy enough to add more. I'm happy to help where I can or give guidance to anyone who wants to participate as well. Anyone up for hacking it into servicemix? :-) - Dan -- Dan Diephouse Envoi Solutions http://envoisolutions.com | http://netzooid.com/blog
Fwd: Websphere 6.1 and MBean registration issue
Hey David, I was wondering if you already had a workable solution for the MBean registration issue? I was thinking instead of putting the code in the AsyncBaseLifecycle it should instead go in the base MBean code. I'll raise a JIRA issue and we can continue discussion of it.

If not I'd like to open the floor to discussions on a possible fix. I don't think so, but you should ping him and cc this list to see if he has worked on it already. I think the possible use of querynames could be fraught with issues especially in clustered environments. Would it be possible to change the base MBean itself so that upon registration it updated the objectName? That way changes would be propagated correctly? I noticed in the code there is references to property change listeners and was wondering whether this meant it was already implemented? Yeah, it should be possible to retrieve the new value of the Objectname and use it instead of the one ServiceMix generates. I think this is the only change to make, but i may miss something: where do you want to propagate the change ? Anyway, property change listeners should generate jmx notifications, provided that the setter call the needed method of course.

Re: [Fwd: What do people think about graduation ?]
I would agree that due to its size and complexity that a TLP makes sense :) On 3/17/07, Alex Boisvert <[EMAIL PROTECTED]> wrote: I agree on both counts.

Re: Why do examples need maven to run
Jeppe, So long as you have built with maven once whilst you are connected, you can always later build using the -o option for an offline build, especially in reference to the examples it is useful (and speeds up the build considerably :) Grant M. On 8/25/06, Jeppe <[EMAIL PROTECTED]> wrote: It seems to me that Maven is not all glory, though it has some nice features, I'm sure. However it seems to make for more brittle builds since the builds are depending on external resources being available and downlaoded. Besides the fact that you might not always be connected. There might be ways around this I guess, to "disconnect" maven from attempting to download new jars. Anyways I think it would be a very good thing if the release is not dependent on maven for building the examples. It would probably be best if they were included pre-built.
