log4j woes with JRun

[Migrated From Jforum.net]

Greetings,

I am attempting to install and whether I follow the automatic or manual process I stumble into this, which I believe is prohibiting me from moving forward. Can anyone offer any suggestions?

My stack trace I get in the event log:

Looks like imcompatibility with log4j jars. See if jrun has in its common shared library directory some log4j jar and the version. JForum uses 1.2.8.
