Do I need to place my java classes in some jar that goes to the lib/ directory in the root of the workflow definition, or is there another way to use the classes outside of a jar?

Java actions in Oozie are run in a Map Reduce job, so yes the classes do need to be wrapped in a jar.
They do not need to be placed in the lib directory though, they can exist in the shared library folder (
oozie.libpath).
