Hello people,
This message has two parts, I wrote the first one as a draft
explaining the problem. And the second exploring the solution.
Email #1 The problem
We set up a GeoNode last week and found out that every time we enable
labels in cached styles we get pink tiles. It seems like GeoWebCache
does not like caching styles with labels, is that a known issue?
I will have to debug this further early next week (because our maps
are starting to look beautiful but we need to be able to add labels.
My plan of action will be:
#1. See if I can completely disable caching for a particular layer (names only).
#2. Dig deeper and get the right stack trace from GeoServer / GWC that
causes the pink tiles.
-------
Email #2 The solution
I tried #2 right away (downloaded geoserver.log from the admin
interface and did a grep for 'label'. I stumbled upon this line:
2011-06-17 22:00:59,483 ERROR [geoserver.ows] -
2 java.lang.Error: Probable fatal error:No fonts found.
3 at
sun.font.FontManager.getDefaultPhysicalFont(FontManager.java:1088)
Which was solved by installing the java fonts package:
sudo apt-get install sun-java6-fonts
I order to fix another issue I also switched from OpenJDK to the
Oracle / Sun JDK therefore I don't know if installing the fonts
package for openjdk will fix it too.
Hope this is useful,
Ariel.
So caching had nothing to do with the problem right? If you don't have fonts I would expect the non-cached wms requests to fail as well. Should we add this to the Ubuntu deployment documentation? -- David Winslow OpenGeo - http://opengeo.org/ On Sun, Jun 19, 2011 at 9:46 PM, Ariel Nunez <ingenieroariel@gmail.com>wrote: > Hello people, > > This message has two parts, I wrote the first one as a draft > explaining the problem.

Yes, I think caching had nothing to do with the problem (but did not edit the title :) ) Yes we should add this to the Ubuntu docs. Ariel.
