Post by: Snake X on August 08, 2011, 04:40:44 pm
This line: Clipboard clipboard = getToolkit().getSystemClipboard();

will not let my applet work. it gives this:

Code: [Select]
--------------------Configuration: link generator - JDK version 1.6.0_26 <Default> - <Default>--------------------

your problem is that the applet is in a sandboxed environment.

Look here (http://download.oracle.com/javase/tutorial/deployment/applet/security.html) right under where it says "Unsigned applets cannot perform the following operations:"

Also, check out this page (http://download.oracle.com/javase/tutorial/deployment/applet/problemsindex.html) for common applet problems.

It looks like you're trying to access something improperly. First of all, you should check that your types are all in order. Also, make sure that you have something in the clipboard beforehand to test it with. Some systems respond differently when the clipboard is empty.

EDIT: Graphmastur is right.
