Question

Since Apple forced the update to JDK 7 on Mac, old AWT applets no longer support copy/paste. For example, if you visit:

Simple AWT Textfield Example

you cannot copy and paste into the applet text field on that page. I’ve confirmed that you can still copy/paste in AWT on Windows with JDK 7.

Anybody know a workaround?

Answer 1

Oracle released Java 6 Update 24 in February 2011 to remedy 21 vulnerabilities: Announcement

As part of this security release, the ability to copy & paste from a computer’s clipboard into a Java applet has been disabled.

To fix this issue there are 2 solutions:

1. Create a digital signature for the applet.
2. Work around: If you do not want to work with the digital signature, add to your java.policy file the following line: permission java.awt.AWTPermission “accessClipboard”
