I have been doing some iOS development over the past year, and have put an app
into the App Store. I'm not an expert...
I think that the thing which would make the most sense is the creation of a
DNS-SD lookup and service bridge for iOS to see and access Jini services. You'd
have to pick an invocation layer that made sense between the two environments,
but practically, you could do mostly all serialization because of the
availability of the JVM native types in iOS. But, invocation, would require
something special/different because of the obvious environment differences if
you didn't actually have a JVM on the iOS device.
From another perspective, with AdHoc distribution, one can put any software you
want onto your iOS device, because it's not approved through the App Store
process. Both simple developer licensing and Enterprise level licensing allow
this to occur. I've not heard of any iOS ports of the JVM though. Practically,
with properly written iOS applications, there is a sandbox to deal with, so some
aspects of Java-SE are not available. There is a limited amount of RAM on iOS
devices, and there are several APIs that provide some caching/virtualization of
resource access for data storage etc.
You may remember that a Sun executive said they'd have Java running on the
iPhone in no time, back in the 2008 time frame. Apple licensing now explicitly
prohibits the use of any secondary execution/compilation environment for app
store apps. This was done to make sure that Adobe would not be able to do
anything to put Flash on iOS. They have to be native apps, compiled from the
Apple tools.
Also, the Mac App Store agreement says you can't use any deprecated technology
in your Mac Apps. Apple deprecated Java just before the Mac App Store agreement
was published. So, no selling Java apps for the Mac through the App Store.
Practically, a 100% Java app could be sold through the app store and then ran on
other platforms, of course.
Realistically, the mass of users using the iPhone and iPad largely have no care
about these details. If they can find apps to allow them to be happy with the
purchase of the device, they are happy. Us technologist, sometimes, can't
understand being happy with "what is there" because we know too much about "what
is not there."
