-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi! In the past days I sucessfully upgraded our XWiki installation from 0.9.840 to 1.1.1. We use jboss-4.2.1.GA and postgresql-8.2.5 and everything went quite well! In the process I only had to remove the servlet-api-2.3.jar from WEB-INF/lib/ as it is incompatible with the one JBoss AS already has. I also added lucene-analyzers-2.0.0.jar as I want to use Lucene's german analyzer. Porting the database for use with XWiki-1.1.1 also went well using the "schema_pre.sql" and "schema_post.sql" scripts Rudolf Van der Leeden posted to this list a few months ago (many thanks, Rudolf!) We now have our wiki with about 2000 pages on version 1.1.1 and are very happy with the results. XWiki-1.1.1 is really amazing and the improvements relative to 0.9.840 are great! Excellent work! There is one thing I still haven't solved, though: The application seems to work fine, but in the logfiles I find lots of the following messages: [...] 19:38:15,510 INFO [STDOUT] 19:38:15,504 ERROR http-0.0.0.0-8080-2 http://test5.intern.xss.co.at:8080/xwiki/bin/view/Main/ SimpleLog4JLogSystem:logVelocityMessage:154 - Left side ($first) of '==' operation has null value.
