Applets, SSL and Java 7 loading error

Post by support »

If you cannot load any applets under HTTPS sinc Java 7 upgrade then have a look to:

A quick workaround is to add:
-Djsse.enableSNIExtension=false in parameters of JRE in Start->Control Panel->Java->Java tab->Display->User tab

Usually, you get a class not found error when applet is loading with following trace in Java console:
handshake alert: unrecognized_name

The bug is reported here:

Another workaround is to serve JAR files from HTTP. It means you will setup web server for HTTPS and HTTP only for one directory including JAR files.

Also, if you're still using HTTPS within applet then you should still add:

Code: Select all

<PARAM NAME="systemvars" VALUE="jsse.enableSNIExtension=false">
systemvars parameter is available since 2.9.1
