Can I deploy wars with different jar versions to Jetty?

Question

I have several webapps but some of them have different versions of the same jars. Can these be deployed to the same Jetty instance?

Answer 1

Yes; this is the reason for recommending packaging dependencies in WEB-INF/lib instead of putting them in the container's classpath. Each Web application in a container gets its own class loader and has distinct runtime instances of the classes it uses.
