Grouper Users - Open Discussion List

[Peter DiCamillo <>]

I've been trying to get the hierarchical ehcache configuration to work, 
which is from GRP-1417 and in API patch 35. I'm doing this with Grouper 
2.3, and I didn't have to convert ehcache.xml because we've never 
changed it. I used grouper.cache.base.properties and 
group.cache.properties from the patch and deleted ehcache.xml. When I 
run the Grouper Shell it seems to start up ok, but in the log file I get:

[main] WARN  ConfigurationFactory.parseConfiguration(134) -  - No 
configuration found. Configuring ehcache from ehcache-failsafe.xml found 
in the classpath: 
jar:file:/opt/local/mace/grouper/GROUPER_2_3_BRANCH/grouper/lib/grouper/ehcache-core-2.4.3.jar!/ehcache-failsafe.xml

and after that around 150 messages like this for different caches:

[main] WARN  AbstractEhcacheRegionFactory.getCache(161) -  - HHH020003: 
Could not find a specific ehcache configuration for cache named 
[org.hibernate.cache.spi.UpdateTimestampsCache]; using defaults.

At that point, if I put back ehcache.xml then the startup is normal. If 
I then keep ehcache.xml but remove grouper.cache.base.properties and 
group.cache.properties, then the Grouper Shell fails to start and I get 
this exception:

So after applying the patch, I only get a normal startup if I have both 
ehcache.xml and the properties files.

While we have no local mods to the Grouper API, we do have UI mods, so I 
build Grouper from the source rather than using patching. But I was very 
careful to examine the patch and update the sources files, and I really 
don't think that's the problem. Let me know if you'd like additional 
information. I have no problem using ehcache.xml, but I thought it would 
be a good idea to include the hierarchical files in our next Grouper 
upgrade.
