A little off this thread's topic, but are there any code examples of simple
remote cache servers using JCS? Unfortunately, I haven't had as much success
getting one set up so quickly. Thanks!

Subject: Remote cache clients JVM will not shut down
Date: Mon, 26 Sep 2005 15:10:35 -0500
Hi. I'm fairly new to JCS. I was happy to get a remote cache server
setup so quickly (< 15 minutes) but seem to have a problem disconnecting
from it. I wrote a little test app that just calls 'getInstance()',
gets an item, puts an item, then calls 'dispose()' on that instance and
quits. But the test app JVM hangs. Poking around shows that the "RMI
Reaper" thread is not a daemon thread. I hoped that calling 'dispose()'
would close down the client's connections to the remote. My
configuration files are largely cut and paste from the examples given on
the JCS page. I scanned the archives of the user's mailing lists, read
a few that looked promising but nothing that seemed to help. Any
thoughts appreciated. Configuration files attached. Thanks.
