Application Server: Tomcat 5.5 Xwiki version: 2.7.33656 I'm encountering several different exceptions that apparently go uncaught, and therefore get logged to Tomcat's standard out log. This causes the standard out log to get filled with a lot of garbage, even though the wiki seemingly runs fine. An example: org.xwiki.velocity.XWikiVelocityException: Failed to evaluate content with id [/templates/xwikivars.vm] ... Caused by: org.apache.velocity.exception.MethodInvocationException: Invocation of method 'hasAccessLevel' in class com.xpn.xwiki.api.XWiki threw exception java.lang.NullPointerException at /templates/xwikivars.vm[line 4, column 25] I would really like to know if anyone can suggest a way to get these uncaught exceptions to be logged to a different file instead. I'm not seeing any way to do so with log4j etc. Thanks, Lenny
