Applets are not running on Internet Explorer 7.0

I think there was an issue with applets on Internet Explorer 7.0. When I tried to run some applets on my windows 2003 server (SP2) box with IE 7.0 and JDK 1.5 version I could not able to load applets on my browser. I tried in almost all known ways by enabling applets through browser setting Tools -->Advanced and from java console (control panel --> java console --> Advanced) but no luck finally I thought to uninstall the java and reinstall it again and did the same but still no luck so finally I have installed lower version of Internet Explorer version 6.0 and it started working...
I think IE 7.0 has some issues still. But IE 7.0 has got some pros and cons as per my limited usage experience...

Pros:

• Rich look and feel
• Tabbed browsing
• Implemented Add-on concept as Mozilla Firefox had.

Cons:

• Though you enable Add-ons still browser through you message that you have not enabled add-on facility which really frustrates.
• As I told Applet issue.
  
• When we say Add-on user will easily sense that MicroSoft is trying to follow Mozilla's style of providing add-on's.

Fix for this issue

It started working by doing this way uninstall IE 7.0 and JDK 1.5 and then start reinstalling IE 7.0 and then install JDK 1.5. This will solve applet issue.
