I wrote a java applet and self signed it. When I run it in eclipse or as a executable jar it works fine. But when I upload it, it doesn't do anything. It loads, and the self signed cert warning does come up and I click yes but nothing. I was under the impression that signed applets had no restrictions. What could be the problem?
You sign your applet with a certificate. If that cert doesn't come from authority such as Thawte in "real life" situation your applet will not be considered safe by your browser without user explicitly granting you access by relaxing Jaca policy (or accepting self-signed cert). Dev tools such as Eclipse have that relaxed policy built in so that's why you don't have a problem
And the pricing is pretty stiff
