I was talking to Jody about WMS-C briefly and he was asking why the list
of demos from this site didn't work.
http://sigma.openplans.org:8080/geowebcache/demo?tiled=true
For wms-c server to work you have to point it at a url that returns an
xml document with a vendor specific capabilities section that contains a
definition of the tilesets. I couldn't figure out how to get that
document from the above url. I tried this without any success.
http://sigma.openplans.org:8080/geowebcache/service/wms?request=GetCapabilities
I also tried the getCapabilities of the main geoserver however was
unable to get a capabilities document that included tileset definitions.
Jody if you want a demo site that works (at least it worked for viewing
data for me) try this site that John identified:
http://labs.metacarta.com/wms-c/Basic.py?SERVICE=WMS&VERSION=1.1.1&REQUEST=GetCapabilities&tiled=true
(As John pointed out there are a few issues with this if we close and
re-open uDig but hopefully these will get sorted soon).

Hello everyone,
I'm starting a custom build that will require features from the trunk,
particularly WMS-C, the custom build involves mostly two fronts:
1. Disk caching TileCache
2. Exporting the disk cache MapInfo .TAB files.
Is anyone currently working on WMS-C? Jody mentioned in an email last month that we
(LISAsoft) might have be getting some work on this, I guess that's my queue to say
"we get the work, YAY!"... so looking at uDig, this is where I'm at:
After building uDig from the trunk, there is a few issues I would like to fix:
testing with:
http://wmsc1.terrapages.net/getpngmap?SERVICE=WMS&VERSION=1.1.1&REQUEST=GetCapabilities&tiled=true
http://labs.metacarta.com/wms-c/Basic.py?SERVICE=WMS&VERSION=1.1.1&REQUEST=GetCapabilities&tiled=true
· Upon restarting uDig, (most times) wms-c layers are not rendered and
causes a NPE here:
java.lang.NullPointerException
at sun.misc.FloatingDecimal.readJavaFormatString(Unknown Source)
at java.lang.Double.parseDouble(Unknown Source)
at
net.refractions.udig.catalog.wmsc.server.TiledWebMapServer.<init>(TiledWebMapServer.java:93)

net.refractions.udig.catalog.internal.wmsc.WMSCServiceImpl.getWMSC(WMSCServiceImpl.java:187)

net.refractions.udig.catalog.internal.wmsc.WMSCServiceImpl.members(WMSCServiceImpl.java:105)
at
net.refractions.udig.catalog.internal.CatalogImpl.getChildById(CatalogImpl.java:537)
at net.refractions.udig.catalog.internal.CatalogImpl.find(CatalogImpl.java:292)
· In Window --> Preferences --> WMS-C Tiles: Disk Cache Location is ignored when
preloading cache (win32), it is instead just downloaded to "c:/tilecache"
· uDig crash's when preloading WMS-C layers, (NPE in
TileImageReadWriter.writeTile) (disk not full)
Possible issues / functionality to be implemented:
· On Disk Cache doesn't populate
Once these are fixed I will need to add:
· Cache expiry rules (as an extension to the current options in WMS-C
Tiles)
· Export plugin to export to MapInfo .TAB files
Cheers,
Johnathon Hudson
