hi!
we're using client/server in a swing based app, and i don't recomend you
to use it too. there are still a lot of problems and unimplemented methods
in the client/server code, some performance killers, ....
i did a some patching and think i know what i'm talking about.

ps: ojb works great in singleVM

Thema: OJB C/S Features
Hello all.
My group is looking for a database model solution and I think OJB might
work,
but after reading the documentation (which is great) I still have a few
questions, mostly about the Client / Server features. Perhaps first I'll
explain what we're looking for:
1. We have a lot of client applications (Swing based) which need database
connectivity. Currently they each have a dedicated database connection
via
JDBC. We'd like to pool those those connections on the server side.
2. However, we can't afford to lose data. So currently each client has a
local
cache and if we lose network connectivity, the data is cached until we can
upload it into the database. If we move to a connection pool we need to
insure
that if either the client or any remote pooling objects lose network
connectivity, the data is properly cached. In other words, we need strong
failover and transaction support.
Now we could probably do an EJB solution, but I'd like to avoid EJB's if
at all
possible. I think OJB's client/server features with perhaps a few
enhancements
might meet our requirements. So here's what I'd like to know:
(1) Is it possible to meet our requirements with OJB?
(2) If not, what's missing? (I'm not afraid to submit patches and
enhancements)
(3) Are there any other open source projects that might be better suited
for
this? For example, I've looked at Turbine's JCS subproject for caching
and I
Avalon might have some components we could use.
Thanks for your advice! The project looks great and I hope I get a chance
to
use it and contribute.
