Problem with applets and Java Plug-in 1.6.0_13

>>x:   clear classloader cache

First of all, try that and then reload the applet

The applet class is on a server. Other user with older versions of the JRE are not having problems. Could it be a security issue with the newer JRE. In the error msg above it says:

Caused by: javax.net.ssl.SSLException: Received fatal alert: unexpected_message

Is there an ssl problem? Could it have something to do with the advanced security settings in the Java Control Panel?

What happened when you tried my suggestion?

I opened the java console and deleted temperary files. Is that different the class loader cache?

Well i don't really get you there as there's no option to delete temporary files at the plugin console. Option x on the keyboard clears the cache. Yes, they *could* be different

I used option x to clear the cache and it still does not work.

OK. Please turn up the trace to 5 and then post the result here after reloading

It works on our dev server but not prod. On dev I get an SSL certificate warning, but on prod I do not get the warning.

I turned the trace up to five and I changed the url to have [OurServer] instead of the actual address.

Here is all I see in the log when it works on dev:

>>. On dev I get an SSL certificate warning,

What is that warning - can you post it? You probably might need to import the cert into your new JRE

See attached image. On the security settings of the advanced tab of the java console wet checked:
Use SSL 2.0 compatible client hello format
Use SSL 3.0
Use TLS 1.0

Then the applet works.
