Not much experience, unfortunately no. Outside of MySQL, most databases need more love in AR-JDBC. This will be an area of focus this summer after JRuby goes 1.0 (or before then if someone is enterprising :). Don't know if it helps, but we actually are running AR-JDBC w/ Derby against AR's test suite (if you can call it running -- 824/1027 failing!). Maybe you can have a look at some of the failures and see if it stirs up any ideas on how to fix the problem. http://jruby.thresher.com/browse/ACTIVERECORD-DERBYTRUNK /Nick _______________________________________________ Jruby-extras-devel mailing list [EMAIL PROTECTED] http://rubyforge.org/mailman/listinfo/jruby-extras-devel
