i configured netBeans (i ' have no error) but when applet is started he is empty. ther is no object like sphere or box on  him.  where i have an error ??.

If you copy your scene setup into a Simple Game and run that, does your scene render?

3

Yes it works.



but in siempleGame i add al pobjects in simpleInitGame() method.



in applet i add it in simpleAppletSetup().  mybe i need to add it in init() applet ??.

4

simpleAppletSetup() should be the right place for you. Have a look at the java console output when you try to run your applet. Maybe something else is going on, like its not loading the lwjgl native or missing jars.

5

i use NetBeans and there is no error (Exception) on console.

6

If you are running your applet from a browser, then the console of netbeans might not be capturing the output. Try checking the java console. It can be turned on from the Java control panel.

LOL it works now.



it didn't works becouse i have in my main class method like



init

start

stop

update.

when i delete them  it work great!!

thanks for help
