Looking for same information, re APEX Listener 2.0.3 on Red Hat Linux - specifically Red Hat Enterprise Linux Server release 5.9 (Tikanga) 2.6.18 348.1.1.el5 (64-bit)..
Have to make a call soon on Glassfish 3.1.2 vs Glassfish 4.0.
We ended up using V3.1.2 since with V4.0, the asupdate script was missing. This script is supposed to run to migrate settings.
It's in there now, for Windows, Web Profile. FWIW.
So far so good,
