TomEE classloader configuration

[Anton Arhipov <an...@gmail.com>]

Hello!

I'd like to know if it is possible to configure TomEE classloader to load
application classes first.
I.e. if in my application there's lib-1.jar and TomEE bundles lib-2.jar
with the same classes, I'd like to load lib-1.jar which is in WEB-INF/lib
of my application.


Thanks,

Note: if you start with the webapp already unpacked you can "hack" the
container pointing to WEB-INF/lib jars in conf/catalina.properties
common.loader property...a bit dirty but should work

IMO, that's the default tomcat behavior and what the spec requires.
Isn't it?

ie. in webapp, you have parent last whereas in a common classloader in
Java, you have parent first

webapp classes are loaded first by default...BUT if lib2 is used before
lib1 is available (typically at container startup) it is not possible

what do you want to override?
