Hi i'm trying JCS for a web page I'm having a problem when i try to 
intance a JCS class:

This is my cache.ccf

jcs.region.InformtationCache.elementattributes.IsLateral=true

Also here is the code:

    private static JCS IntiCache() {
        if (InformtationCache == null)
            try {
                InformtationCache = JCS.getInstance("InformtationCache");
            } catch (Exception e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }

        return InformtationCache;
    }
   

for the record I'm using tomcat 5.5.X with SUN JDK 5 update 11 in windows.

thax for the help ;)

Same problem with

# DEFAULT CACHE REGION

# sets the default aux value for any non configured caches
jcs.default=DC,RFailover
jcs.default.cacheattributes=
    org.apache.jcs.engine.CompositeCacheAttributes
jcs.default.cacheattributes.MaxObjects=1000
jcs.default.cacheattributes.MemoryCacheName=
    org.apache.jcs.engine.memory.lru.LRUMemoryCache
jcs.default.elementattributes.IsEternal=false
jcs.default.elementattributes.MaxLifeSeconds=3600
jcs.default.elementattributes.IdleTime=1800
jcs.default.elementattributes.IsSpool=true
jcs.default.elementattributes.IsRemote=true
jcs.default.elementattributes.IsLateral=true

added to my cff
