- Q: Why can't I run Java applets in the SWT Browser?
- A: Applets usually don't show up in the SWT Browser. On Windows (Internet Explorer), the Java plugin fails to run a second Java virtual machine to execute the applet because two Java virtual machines cannot run in the same process. On Linux (Mozilla), the Java plug-in has been reported to work because it executes in its own process. See bug 59506 .
