    If you want to upload your midlet to a device, first upload your jar file somewhere (any website will do, boards.ie even).

    Then go to this site...

    http://www.mobilesheaven.com/en/

    Register and upload your JAD file which points to your jar. Then point your phone to the JAD file and it will upload your midlet for you.

    Also if you plan to design/write games I would strongly recommend "Ultimate Game Design: Building Game Worlds" by Tom Meigs. You can also pick up at Amazon

    ..........

    Another site to check -> http://midlet.org/index.jsp

    To actually compile your code use the The Java Sun J2ME Wireless Toolkit v.2.1

    or The Nokia Deveopers Suite

    Note these aren't used to code your application/game, they are just compilers.

    To do my coding i like to use Textpad
    Indeed i use textpad for all my coding wheather it be C,C++,Java,ASP etc...

    Another thing to note is that if your using a tiledlayer in your application and run it on the wireless toolkit it will appear very laggy, this is a bug which doesn't happen when its transferred to a phone.

    ps. make this a sticky?

    For coding purposes I recommend Editplus 2, search Download.com for it, its the business.

    Sorry for reviving this old thread. But i can't get the above code to work. I've installed it on my webserver but when i navigate to it from my phone and click on one of the files i've placed in that directory it just leads me to another page which lists all the files in that directory in a html format. However i need to use the server with a phone that doesn't support html/xhtml. Anyone know what's up.

    If you are gonna be doing any sort of developing at all get a bluetooth dongle on ebay for about a tenner or if your phone dosent suppport bluetooth get a USB cable. Downloading your app via wap everytime you want to test it is not the answer.
