Hi Mr. Hudson,
We are not currently working on the WMS-C tile caching. It is possible
it has some bugs as it was developed as a first step and version. And
the tile preloading can definitely put a large strain on uDig and your
system since it is literally sending thousands of requests and writing
them to disk (in queued groups of course) but it doesn't surprise me
that it could crash. If you see areas for improvements please feel free
do to so.

Hi Mr Hudson:
Sounds like you have your first couple of bugs to report; Graham Davis
was the developer working on this stuff and he may or may not be aware
of the problem. While you wait to hear from him perhaps you can look
into where the problem occurs and make a patch?

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://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
<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.CatalogImpl.find(_CatalogImpl.java:292_)
· In Window à Preferences à 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,
