I am using CompositeCacheManager.getUnconfiguredInstance(); and configuring it programatically with the following properties:
jcs.default=DC jcs.default.cacheattributes=org.apache.jcs.engine.CompositeCacheAttributes jcs.default.cacheattributes.MaxObjects=0 jcs.default.cacheattributes.MemoryCacheName=org.apache.jcs.engine.memory.lru.LRUMemoryCache jcs.auxiliary.DC=org.apache.jcs.auxiliary.disk.indexed.IndexedDiskCacheFactory jcs.auxiliary.DC.attributes=org.apache.jcs.auxiliary.disk.indexed.IndexedDiskCacheAttributes jcs.auxiliary.DC.attributes.DiskPath=C:\path\etc jcs.auxiliary.DC.attributes.MaxKeySize=1000 jcs.auxiliary.DC.attributes.OptimizeAtRemoveCount=1000 My main aims are: - guaranteed persistence - once I've added it to the cache, even if the application crashes, the key value pair will still be available when the app starts up again - a non-infinite cache - I want the number of items in the cache to not exceed order of 1000 to conserve disk space, though the exact number is not important. Do these sound like something that is possible with JCS? I've looked through all the documentation and can't find anything along these lines. Thanks, Tim.
