problems getting jcs working

hi,

i am using jcs-1.2-6-5.
my cache.ccf looks like:

# DEFAULT CACHE REGION

jcs.default=DC,LTCP
jcs.default.cacheattributes=
     org.apache.jcs.engine.CompositeCacheAttributes
jcs.default.cacheattributes.MaxObjects=1000
jcs.default.cacheattributes.MemoryCacheName=
     org.apache.jcs.engine.memory.lru.LRUMemoryCache


i implemented a first test based on the basic web example descibed in 
the user guide and getting the following exception:



[06-16 11:19:03]main (CompositeCacheManager.java:89) - Instance is null, 
creating with default config

any ideas what's missing?

right, this was my entire config file. i remember reading that if you 
don't define DC, LTCP jcs will fall back to default values. i have a try 
with your sample. thanx.

Please send your entire cache.ccf. 

This references DC and LTCP but neither are defined. 
Think of these as log4j appenders.  If you reference
them, you ahve to define them.

A complete file would look like this (between the
dashes):
