Applet is not looking for the classes in the jar

Question

I have an applet that uses 2 jar files (Jasplet.jar and WinLS.jar). They are downloaded fine, but then java look for the classes in a URL instead of using the jar:

I have tried to clear the cache. I even deleted mi ~/.java/deployment directory. Any idea of what could be the problem?

Answer 1

Your applet appears to be asking for https:// protocol security.
Is there a certificate should be in your localhost server and https enabled and supported
(the applet continually asks for "https protocol" types of information and your using standard http)?
Other protocols for such use are ssl:// and tls://
Dependent the server configuration you may or may not require the port number on the end of the domain
e.g. something like.
ssl://mydomain.com:443 or https://mydomain.com:8080 or tls://mydomain.com:989
And be sure there program if its an extra such as ssl:// has its service started.
