cache passivation problem
dan.washusen Mar 14, 2007 2:16 AMHi all,
I seem to be having some problems getting the passivation functionality working with jboss-cache 1.4.1.SP2. I'm expecting the cache to write the entry to disk whenever I call the put method, but it doesn't seem to be happening.
The documentation and other posts on this forum seem to suggest that I can just set the passivation property to "true" in my CacheLoaderConfiguration and it should just work. As far as I can tell, it's just creating an empty directory matching the location property and nothing else...
I've essentially just copied the CacheLoaderConfiguration element from the provided "local-passivation-service.xml" file into the "replSync-service.xml" file and commented out the TransactionManagerLookupClass property as I'm running in tomcat.
