What the expected output?
Bundle as directory that is ready to go to dmg/pkg? or dmg itself?
a) How one specify set of jars?
b) What if application expects jars/resources to be in the multiple
c) How do i specify data or other resource files to be included?
d) How do i add native libs?
e) Can i add custom frameworks, etc?
f) Why we refer to Java Runtime?
IMHO, we could assume people install JDK and should point to JDK
bundle root as root for cobundle.
Ant task need to be aware of how to find files in the bundle.
This will simplify life of IDEs such as NB as they only keep
track of where current SDK is located.
g) Any way to specify minimum platform requirements (even dmg has it)?
DMG also allows to include images, release notes, etc. And what
folder to drag app into (by default Applications)
Obviously most of customization options could/should be optional
elements but people like to tune these things.
h) can i select subset of runtime? E.g. not include javafx, etc.
Perhaps java could be separate element?
Do we have any docs explaining task parameters?
Overall, IMHO, it make sense to see if we can extend approach/syntax we
use to bundle javafx apps.
We do not support dmg bundles there (yet) but we clear want to and
javafx will be part of java platform soon.
It would be nice to have these to play nice together from the beginning.
Specifically i am thinking it will be useful to have
a) some kind of "resource" element that could include arbitrary set
And resources could be of different types (e.g. jars, native,
frameworks, icon, "custom", etc)
b) application descriptor - most of what you have on bundledapp
(but not java runtime location, dest file, etc.)
c) some kind of target image abstraction
(icon and other dmg properties)
What do you think?

>> I'm wondering where this should be checked in, though. Building an application bundle from JARs, resources, and launcher stub is really a deployment task as opposed to a pure JDK feature, but Web Start and the plugin are not open sourced so I don't see a public 'deploy' project happening in the near future. We definitely want to push this out so people can start building applications with the Mac JDK. Anyone have an opinion on that?
>> Also, we are working on an simpler version of the launcher code that will reuse more of the generic/command-line launcher code in jdk/src/share/bin/java.c. Kumar Srinivasan checked in a refactoring of the command-line tools so that all of the runloop management, argument parsing, and other setup is now done in JLI_Launch. That means we can rip out the code that duplicates that work in the app launcher and call through to JLI_Launch instead. I started on this and handed it off to Greg. We should have something to share in the next week or so.
