>300 LOC to cause a one line failure? You need to develop some better debugging skills at least to the point where you can identify which LOC caused the problem. And for better help sooner, post an MCVE (Minimal Complete and Verifiable Example). — Andrew Thompson

The problem is this line:

frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

When setting EXIT_ON_CLOSE we are effectively trying to get the JVM to shut down itself as soon as the frame is closed. An applet security manager (even when the applet is trusted) will prevent that.

It should be:

frame.setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE);

That will fix the immediate problem, but a better solution is to scrap the applet and put all the necessary controls in a frame. After that is accomplished, launch the frame using Java Web Start.

Thank you for your answer but it still doesn't work, same exception, I tried to sign my jar files but it doesn't help ether

Andrew Thompson Over a year ago

Are you positive the changed code is being loaded by the browser? BTW - ensure the Java Console is configured to show for applets & JWS apps. Clear the class cache between tests (see console for details). What about "..launch the frame using Java Web Start"? Are you intending to ignore that advice?

OK I got my error it was because I had JFrames, when I deleted it it worked thanks :)

"error it was because I had JFrames" No it wasn't. My answer explained why the code had the error. Try reading it again.
