Btw, what I miss in the wiki section is the pretty common ulimit error on *nix.
Most unixoid systems (like Linux) have a standard quota of 1024 file handles per process. This is not enough for building OpenJPA on a Linux box and you will most likely get funny IO exceptions. You might have to edit /etc/security/limits.conf and add the following (or adequat) lines to increase the ulimit: [insertyourusername] hard nofile 4096 [insertyourusername] soft nofile 4096 LieGrue, strub ----- Ursprüngliche Mail ---- > Von: Pinaki Poddar <[email protected]> > An: [email protected] > Gesendet: Mittwoch, den 5.
