Hi, I'm trying to use ehcache with terracotta
I'm new to terracotta I just pass simple dso tutorial and then I next to ehcache tutorial then I got error

*** Sorry, this class just mess up with two tutorial in one, but I think it should not be matter.

and then I found that if I add some transient-fields in config file my code works, but I think it not required to do so, right? no any mention about put these fields into config, I think I follow exact the way as the tutorial but it not works, what I do wrong?

I run tc server from TC_HOME/bin/start-tc-server.bat

then run client within netbeans with java options
-Xbootclasspath/p:"D:\Terracotta\terracotta-2.6.2\lib\dso-boot\dso-boot-hotspot_win32_160_07.jar" -Dtc.install-root="D:\Terracotta\terracotta-2.6.2" -Dtc.config=tc-config-example.xml

I suspect you have a cacheEventListenerFactory configured in your ehcache.xml for cache replication. When using Terracotta, this is not needed as Terracotta handles the distributed cache replication. Can you either confirm or post your ehcache.xml?

You will need to remove the cacheEventListenerFactory from ehcache.xml when working with Terracotta.

Ahhh, thank you so much.
I really have cacheEventListenerFactory in config of other sample caches of ehcache.xml
it works now after I remove all of them except the default and the albumCache.

I filed a jira ( http://jira.terracotta.org/jira/browse/FORGE-274 ) in our system to deal with this scenario in a less confusing manner. Thanks...
