1.4 support and Java ME

+1... I kind of counted on it, too.

Doesn't ending support for Java 1.4 mean it will become impossible to
write apps for phones in Scala?

Probably Retrotranslator is your friend.

BTW, are there any real phone applications in Scala? Hello world does not count.

Thanks for the hint;
as to the app, I've just started working in a phone app company...

• So what's the difference between Retrotranslator, Retroweaver, and JBossRetro?
  
• How much more limited is Java ME than Java 1.4?
• Mainly, what's the best way to integrate into Eclipse?

I just tried out the Sprint Titan eclipse plugin, so I can program for my Touch Pro. It uses OSGi, so it works with plugin projects.So I need a Scala plugin project that has an extra build step? Should that work? What are the instructions for that? (Then I have to see if it breaks Sprint's functionality, like installing onto the emulator...)
Sorry if these questions are outside of the scope of the list. The important question addressed to the list is if there's anything unique to scala here, I guess...

I would be really interested hear of anyone who has actually written and
deployed a significant J2ME app from Scala (and how you did it).

Basically because I would like to do the same thing myself, but had
assumed that its not feasible. Scala dropped the CDLC compile target
some time ago. Idiomatic Scala will likely generate too many classfiles
to fit on a phone anyway.

I didnt know of retrotranslator til now. It looks good.

Retroweaver is older (IMO) abandonware that should not be trusted. I attempted to use it to support Java5 on J2ME, and found that it generated illegal exception tables in some bytecode.

Heaps - its another world. No collections, reflection or serialization,
for starters.

I greatly enjoy using EclipseME. Retroguard obfuscator is another
excellent tool.

I assume that both points refer to CLDC. I should have been more clear that I'm fine with CDC. Thanks!
