Using a differnent version of a jar than the one supplied with Tomee

Question

I am trying to port a web-application to Tomee (Apache TomEE 1.5.2) but I have hit a major hurdle.

The version of quartz our application uses clashes with the bundled version of quartz.

Tomee comes with quartz-2.1.6.jar which is loaded as part of the container set-up as far as I can tell, But our application relies on a very old version of Quartz and we are unable to update at this point in time.

From research I had assumed it would be enough to place the older quarts jar in the WEB-INF/lib of my web-app and as per the Tomcat class loading information here it would be looked up before the quartz-2.1.6.jar in the ${catalina.home}/lib directory, this doesn't seem to be the case.

Is it possible for Tomee to use the bundled version of Quartz and my web-app to use a different version of Quartz?

Thanks to Romain Manni-Bucau.

The solution was to add

openejb.classloader.forced-load=org.quartz
