I am trying to launch an applet from another applet. When run such applet from Mozilla Firefox, it runs without any problem, but when I try it on IE (IE7 on XP), it does not work. I mean one applet get executed but it's not launching another applet. The pack of .class files and html file can be found at 'http://www.geocities.com/prithvi2007/testQuick.zip' for test. The source file is available at 'http://www.java-tips.org/java-se-tips/java.applet/have-an-applet-launch-another-applet.html'.
The strange thing that I have noticed is that when I run the same html file from the editPlus, it runs fine although editPlus is using same IE7 browser of the machine.
That's a hack. I wouldn't want to rely on that working across browsers and platforms (and, apparently, it doesn't).
You can avoid the lengthy download of a big jar file by having the first few classes -that are sufficient to show the applet- as loose classes in the directory, and then access any classes in the jar file once the applet is up and running.
