For a read-only cache, we can just use a JCS distributed cache.

P.S. in my discussions of LockServers, I assumed that everyone would
realise that the LockServer doesn't become a central point of failure. In
case
some people didn't realise; well, it doesn't. Failure of the LockServer
would
mean that servers were no longer able to access the cache. It would not stop
them reading data directly from the database. The "lock" doesn't represent a
lock upon a data item. It represents a lock upon the *cached* data item.
No transaction may ever block another transaction inside the persistence
layer. The database itself manages concurrency issues.
