[rjb-users] Can't find jarfile classes with Rails

[rjb-users at rubyforge.org]

Hi Arton,

Well, at least we've narrowed it down to my platform.
Was the other user's platform also Linux amd64?

$ cat /proc/version
Linux version 2.6.17-5mdv (rtp at ramanujan.mandriva.com)
(gcc version 4.1.1 20060724 (prerelease) (4.1.1-3mdk))
#1 SMP Wed Sep 13 14:28:02 EDT 2006

$ ruby -v
ruby 1.8.5 (2006-08-25) [x86_64-linux-gnu]

$ rails -v
Rails 1.1.6


$ java -version
java version "1.5.0_09"
Java(TM) 2 Runtime Environment, Standard Edition
(build 1.5.0_09-b01)
Java HotSpot(TM) 64-Bit Server VM (build 1.5.0_09-b01,
mixed mode)
