There is nothing out-of-the ordinary, just put all the jars in common/lib. Or you can put all of them in the classpath and call o.a.catalina.startup.Catalina instead of bootstrap, but I'm not sure it'll work ( it does for what I'm using - 5.0 head ). > > If you mean putting everything -- all the jar files mentioned in that > document into $CATALINA_HOME/common/lib... Yes. That would put everything in the 'main' classloader. You loose the separation - and it may be slightly more insecure. AFAIK the classloader separation doesn't add extra protection if the sandbox is disabled - and the facades are protecting the internals.
