As I stated in a previous email events on 1.7.x do not work like they do on trunk, because of the way the config system works, and basically updates the entire catalog when a single change is applied.
The only option is to use CatalogListener.reloaded() method to latch onto the change event as a whole, but it won't be possible to watch things change in a granular way.
The config system, which went through a major re-architecture for 2.0, on trunk now fixed this.

Justin,
I hooked this up but I noticed that the CatalogImpl class does not
generate any events when I add coveragestores, featuretypes, etc. from
the Configuration console.Is there a reason for that? Or is that a bug?
I'm using Geoserver 1.7.5.

Subject: Re: [Geoserver-users] Java OGC Web Services Client SDKWell.. .there is the CatalogListener interface, which can be used to listen to catalog events. However, on 1.7.x it will the tricky. The way things work is that when something in the catalog gets changed, everything gets updated. So tracking what changed is hard. I guess your listener could maintain an internal list, to see what changed on an event, but it would be a pain.
On trunk however, the events are granular, so you only get an event for what changed.
In both cases, once your listener knows what changed, it would be relatively easy to simply write the result to out a rss feed.

Thanks Justin...as is usual with me I found the answer right after I
posted to the mailing list...I'm going to try to write that GeoRSS feed for changes to the wms/wfs
catalogs so interested clients can learn of changes to the catalog
(add/remove layers and layer groups).I'm trying to determine an estimate on that now so I can determine
whether I should go down this path. Otherwise, I'll have to generate a
custom GeoRSS external to geoserver using a cron job...grrrr-----Original Message-----

Hi all,
I had a quick question where I was wondering if anyone knew of a Java
OGC Web Services Client SDK. I figure this has been done to death and
must exist out there.
Can anyone point me to an SDK I can use in my program to extract
layers,
features, etc. from Geoserver?
Thanks!!
