Compiling Midlets on a T-Mobile Dash or other Smartphone

[winhax]

I've been wondering is there any way to set up a JavaME environment on a Smartphone, specifically a T-mobile Dash? Not a JavaSE environment but one that utilizes CDLC and MIDP. I have a wireless keyboard that I use with my Dash and I'm a self-labeled Gnork (Geek, Nerd, Dork) and I rarely use my Smartphone as just a Phone/PDA. I was working on an RPG and on my breaks at work or whenever I have a few minutes I pull out my Dash and edit source code. If anyone has any ideas or suggestions please let me know. Or, if this is a lost cause please let me know so I can start working on something else.

Thanks,

J

How about an online compiler?

I am not as gnork-y as you (yet I aspire), so I don't know if this, or something similar, would work.

That would work but I was looking for a way to create the .jar file directly online; not a JavaSE .jar, a JavaME .jar compiled completely online on on mobile.

Sorry, then - I've got nothing!

Ok, I figured it out. If anyone is interested in creating a Midlet directly on your smartphone and/or Pocket PC, here's what I did.

1. Create your .java files, resource files, and MANIFEST.MF (on your computer or on your smartphone).
2. Use the online JXXX Compiler service (JXXX Compiler Service) or Mysaifu (http://www2s.biglobe.ne.jp/~dat/java/project/jvm/index_en.html) to compile your .java files into .class files.
3. Use Total Commander (or equivalent file manager, with ability to pack files into a .zip archive) to create a folder called "META-INF" (without quotes).
4. Place your MANIFEST.MF file into the "META-INF" folder.
5. Use the pack command in Total Commander to pack all the files into a new midlet.zip file (make sure you don't create a zip with a folder holding your files, only add the files you would normally .jar archive).
6. Rename the midlet.zip to midlet.jar.
7. install the midlet.jar from within your favorite midlet manager.

That's what I came up with. Let me know if anyone has a faster or easier way.
