Java Applet to Stand alone application

[Marcio Morgado]

Hi i was wondering if anyone could convert this to a stand alone application. My phone (HTC Touch) doesn't seem to want to run the applet and since it had ran java application i wanna give it a try.
Thanks in advance.

Welcome to JavaRanch.

I'm not sure what "doesn't seem to want to run" means, but I think that http://faq.javaranch.com/java/AppletsFaq#application may help you a lot.

sorry i guess i was kinda of loose on it. My phone will run java applications and java games. But it won't load it the java applets i think it's the browser but not sure since there isn't a setting for java. But thanks for the link it gave me some more incite.
