I'd be in favour of seeing Romain's URLClassLoaderFirst option. I'm not
sure about changing the default setting though. Perhaps we could look for
clashing libraries as part of the scan when deploying an application and
throw up an appropriate warning steering users towards the new setting if
they run into problems?
Davide's suggestion of the JBoss 7 style classloader is an interesting one.
I'm not a big fan of the JBoss/modules structure myself, but I can
understand the appeal. I can imagine it wouldn't be too difficult to write
something to parse the jboss-deployment-structure.xml file and add the
necessary entries to the classpath of the application. Would be great for
existing JBoss / Wildfly users looking to give TomEE a try.
I would have thought we could also provide support for skinny wars/ears by
allowing Class-path entries in MANIFEST.MF where they are either looked up
from a directory within TomEE, or specified like Class-path:
${catalina.home}/modules/mymodule.jar.
Just a thought. Happy to have a go at working on any of these if anyone
likes any of these ideas.
