ClassNotFound : Open HTTP Connection Failed

[Julien Grenier]

Hi all,
My applet is working find with Firefox and the JRE1.3.1_09 but it gives me the following error with Iexplore : ClassNotFound myapplet.class; java.io.IOException : Open HTTP Connection Failed .

I've look over the web it's look to be a proxy problem but then why the problem doesn't occur with Firefox and the same JRE on the same machine?

any cue?

Check your Internet security settings. Try unchecking the option that specifies IE to use a higher version of JRE for displaying applets.

If you are doin an I/O from the applet, then you might have to set the policy (".java.policy" file) in your system (using policytool.exe) and grant required permissions.

Could you copy and paste here the full error message from the Java console?

I'm curious how not finding your class is related to the HTTPConnection problem. Perhaps the stack trace in the error message will show that.

Thanks Sravan Kumar. I will look into that.

here's a similar error to what I had (I don't have a exact copy of my error [it occurred on another pc and I don't have the log right now])

Ok, I'll wait for the real one.
I've never seen following in stack trace, but I'll keep trying.
