classpath = bin/bootstrap.jar + bin/tomcat-juli.jar | |- common.loader = lib/*.jar | ` webapp = web-inf/lib + web-inf/classes *Romain Manni-Bucau* *Twitter: @rmannibucau <https://twitter.com/rmannibucau>* *Blog: **http://rmannibucau.wordpress.com/*<http://rmannibucau.wordpress.com/> *LinkedIn: **http://fr.linkedin.com/in/rmannibucau* *Github: https://github.com/rmannibucau* 2013/2/6 Alex The Rocker <[email protected]> > Okay I understand versions in TomEE jars are here to stay. > Our installer is not a public one. > How about my other questions : how TomEE knows which .jar files must be > loaded? does it "scans" the lib/ directory? > Can we safely rename TomEE's .jar files without changing anything else? > > thanks, > Alex. > > > On Wed, Feb 6, 2013 at 11:34 PM, Romain Manni-Bucau > <[email protected]>wrote: > > > if you keep multiple versions all will be broken (excepted if you are > lucky > > but i'd not bet on it) > > > > you can remove the version in your process no? > > > > Tomcat and TomEE are different because Tomcat doesn't rely on external > > libraries (they either forked or rewrote everything) so they can manage > > easily their deps.
