Newbie: pulling my hair out with remote cache

[David Vismans <da...@chello.nl>]

Hi everyone,

First, JCS looks great! Looking forward to some extensive usage.
However, I have been trying to get the remote cache working for about a
week now, and I am not succeeding.

Here's the setup:

C1 (client 1) pushes an element E in it's local cache.
CS (server) receives (the update of) this object and does store it.

C2 (client 2) is able to retrieve the cached element E from CS.

so far so good,

but when C1 repetitively updates E (named "test") with a random integer
value,
C2 is not notified of the new value for this key. CS DOES receive the
element, but does not propagate to C2.

I have read through every example and also mailinglist messages I still
have not found the solution.

I got JCS from the CVS and RMI is working, I created the stubs etc.
I am using the latest jdk on windows xp home edition.

Perhaps an interesting detail: I did not get the lateral cache to
propagate either (there is no firewall running). All clients and the
server run on the same machine.

If anyone could help me out here I would really appreciate it!

Thanks in advance,

David
