No applets loading within browsers

Since I had a fiddle with Eclipse, such that it uses Java 1.3 to run applets, no applets will load (on _any_ site).

I've checked all of the IE settings, and have rebooted, etc.. but no luck.

The problem, really, is that I cannot remember what option I set in eclipse to make it load applets using 1.3... lol.  <slaps head>.

So.. how can I change it back to 1.5 ?  :-)

Thanks.

Touching Eclipse shouldn't have an effect on the browser i don't think. YOu need to check the Java plugin in Control Panel

Make sure you haven't fiddled with IE security. When you try, does the plugin icon come up in the systray?

No, it doesn't.  :\

I've had a look at my IE security settings, and it all seems fine ...

Go back into the Control Panel and set the plugin to appear. This may give you some clues

Commented:
If your talking about it eclipse here its just under the jre settings of eclipse you can set that on the project.
Right click the project then properties look for the Java Compiler or go to menu's Window > Preferences > 
Java > Installed JRE's then unselect the Java 1.3 and pick your latest.

Hm. Doesn't look like it's eclipse then..


In the Windows Control Panel, there's also an item called "Java Plug-in 1.3.1_18". In here, under the "Browser" tab, neither IE or Netscape 6 are selected..

So, I tried selecting the IE one, and then restarted the browser.. but I get some 'Visual C++' error ..


BTW; when I attempt to load an applet within the browser, it says in the bottom left corner of the browser "load: class <package.classname> not found"..

If its checked then un checked it and check the latest version :D

> "load: class <package.classname> not found"
Did you bundled the required packages on the jar file of the applet or are there any packages u think are missing?

Well, I get this exact same problem for _all_ applets ...
Even the one here:

Okay, I've unchecked them...
There's no "Java Plug-in 1.5..", but there is a "Java" item; in here, all of my settings seem fine also - and it even says that it will use Java 1.5 for applets..

I recently installed JRE 1.3 -- in addition to 1.5.
This is so that I can compile and run my applets in 1.3 (seeing as a lot of people still don't have 1.5)...

Yep ;) you may wanna opt to using 1.4.2 insteadof 1.3, its the latest stable standard usable today next 1.5

I think you need to (re)install the 1.5 JRE

try doing it the other way around.

Uninstall both, then install 1.3, then 1.5.
