Re: [WDSCI-L] JSF and App Servers

Aaron,

Bring this up on the Ignite list and watch Cancilla blow a gasket!  We
get our 520 with WAS-E in a week or so; I'm already worrying about
this one.  From what I've been told, it sounds like web assets (like
images and such) can't really be reused easily.  You stick them in the
EAR, and that's where they live.

My question (sort of in the same vein) is should I have different
EAR's for the different "applications" on my site (shipment tracking,
transit time lookup, rate quote), or should all of my interactive apps
be in one EAR?
