Generate all icon sizes for your apps.
Actually it’s a pain in the neck to resize icons for every app that you develop. I prefer to draw largest icon for example 512×512 or 1024×1024 and the others will be made. The Appiconizer is an open source solution to resize icon for the selected sizes.
If you just want to run the app from java web start, please add "https://dl.dropboxusercontent.com/s/" as your security exceptions in java control panel applet. Then start jnlp from here (Dropbox link): https://dl.dropboxusercontent.com/s/jzsm3r96fkpxcq0/appstart.jnlp
