You need to set up the correct environment in your thread as otherwise all bets are off :) We do that in lots of places; just to name a few: * The main Servlet thread * Stats * Lucene Updater and Rebuilder * Linkchecker * IRCBot thread In the future I'd like to have common initialization code that can be easily reused. We have a bit of this already with AbstractXWikiRunnable which are extended by Lucene Updater and Rebuilder threads for example. -Vincent _______________________________________________ devs mailing list [email protected] http://lists.xwiki.org/mailman/listinfo/devs
