Hi Bret, *As far as I know* (-caveat!) your object doesn't need to be serializable if you are just using the memory cache. So you can cache any random object. It needs to be serializable if it will ever leave the JVM however - so if you have configured any kind of disk caching for example, your object would need to be serializable so it can be moved from the JVM out to disk. I think in the examples on the web pages configure a disk cache.
Try a minimal ccf file like this: jcs.default= jcs.default.cacheattributes=org.apache.jcs.engine.CompositeCacheAttributes jcs.default.cacheattributes.MaxObjects=10000 jcs.default.cacheattributes.MemoryCacheName=org.apache.jcs.engine.memory.lru.LRUMemoryCache jcs.default.cacheattributes.UseMemoryShrinker=false jcs.default.elementattributes=org.apache.jcs.engine.ElementAttributes jcs.default.elementattributes.IsEternal=false jcs.default.elementattributes.IsLateral=false jcs.default.elementattributes.IsRemote=false jcs.default.elementattributes.IsSpool=false Regards, Niall On Tue, 2008-07-08 at 23:29 -0500, Bret Schuhmacher wrote: > No, just an object.
