The following document illustrates several basic JCS configurations. As you'll see, using JCS can be as simple as creating a single memory cache for you application. However, with a few configuration changes, you can quickly enable some distributed caching features that can scale your application even further.
A few comments on configuration
Auxiliary definitions are like log4j appenders, they are defines and then associated with a region like a log4j category.
The order of configuration file is unimportant, though you should try to keep it organized for your own sake.
Configuration is being refactored and is subject to change. It should only become easier.
The complete file
The complete file from above would look like this:
