> How to build an element key

> Key: JCS-47

> I use a string as key for my elements. Now I was surprised to get this error
> message:
> 11:07:52,257 INFO [CacheEventQueue] Cache event queue created:
> CacheEventQueue [listenerId=1501085802, cacheName=cache]
> 11:07:53,000 INFO [STDOUT] org.apache.jcs.access.exception.CacheException:
> key must not end with : for a put operation
> I guess this means that colon is a special character, and can't be freely
> used as a key.
> Unfortunately, I couldn't find any documentation on the project website what
> the constrains are for keys. It would also be interested to know if there is
> anything else to be considered when choosing the key, e.g. is there an
> advantage in using shorter keys?
