Log4j start-up errors in Servicemix.

pchandler May 14, 2009 4:30 PM

I down loaded FUSE 4.0.4 "ServiceMix (1.0.3.0-fuse)" I got this error out of the Box on start up. Any ideas on how to fix it?

It looks like a pax logging service starting up issue.
Did you change any thing on the Fuse ESB 4.0.4?
And What's your system environment ?

Is it possible that there's something in your classpath that's causing this, have you tried unsetting the CLASSPATH variable in your environment to see if that helps? Also have you tried 4.1 to see if it still occurs there? I haven't seen this personally on Linux so it's hard to say what's going on but it's likely going to be down to something in your environment.

I unset my CLASSPATH and the errors cleared!

Using/traversing the Uses/shells existing CLASSPATH to find servicemix log4j artifacts (i.e., jars, appenders, property files, ...) - interesting?

Thanks again,

Peter.
