How to run multiple nuxeo WARs on one Tomcat?

Hi all,

I tried on a tomcat server 7.0.61 to run multiple nuxeo 7.2 instances, built according to http://doc.nuxeo.com/x/HoeN, but errors occured during the startup of the server:

localhost-startStop-1 10:42:22,112 ERROR [RegistrationInfoImpl] Component notification of application started failed.{}

        ... 22 more

It looks like there is a conflict between the Nuxeo instances. Is there a way to make it works please? Is there some configuration missing in the nuxeo web.xml or context.xml files? Or is it necessary to move some nuxeo libs in the $TOMCAT/lib shared classloader?

Thanks in advance
