Long Filename Help
For everyone having a problem with the long filenames. You can't just change the name of the .jar file. You also have to change the "MIDlet-Jar-URL:" inside the .jad file to whatever it is you renamed the .jar file to.

As an example :

We'll use Jamdat Bowling game

1. Rename the .jar and .jad files to JDBowl.jar, and JDBowl.jad    (or what ever you want but keep it simple)
2. Open the JDBowl.jad file (notepad) and find the line that says        "MIDlet-Jar-URL: jamdat_bowling.jar"
3. Change that line so it says: ""MIDlet-Jar-URL: JDBowl.jar"
