Folks:
I've been trying to install Xwiki on a Suse 10.2 linux distribution with apache-tomcat-6.0.16 and MySQL 5.0.26 (the jdbc driver is mysql-connector-java-5.0.8.jar).
With either Xwiki 1.2.2 or 1.3.rc1 i get a null pointer exception when I get to the XWikiPreferences page i.e. http://localhost:8080/xwiki/bin/objectadd/XWiki/XWikiPreferences?classname=X... for 1.2.2. Using 1.3 the error is terminal (no way to recover). Using 1.2.2 if I click on the XWikiPreferences header then I see a normal page, instead of the exception trace. Except, if I try, say, to save a comment, I get another trace.
I am not sure, but this sounds not far from a problem Sergiu Dumitriu has been working out yesterday night in the IRC channel. Please, just hoping he and others have e while to follow this thread, could you provide us with some extra information? It would be great if you could submit a couple of SQL statements to your database and post here the answers. MySQL Console or MySQL Query Browser could be used for this. Considering the database you are connected to is xwiki: 1. desc xwiki.xwikircs 2. select count(*) from xwiki.xwikircs where xwr_isdiff is null I think this will help to know if we are facing the same problem.
