After update to Java version7 update 51, I purchased the code signing certificate and signed my applet(s). I have main applet (AppletDemo.jar) and another two applets (commons-codec-1.7.jar and FDxSDKPro.jar) which are used by main applet. I signed them all, with DigiCert certificate.

All of them are signed, and verified with jarsigner tool where i get such message:

*s = signature was verified
m = entry is listed in manifest
k = at least one certificate was found in keystore
i = at least one certificate was found in identity scope
jar verified.*

When I try to load the applet I get the following message in the java debug console (the real url is replaced with tag):

basic: Plugin2ClassLoader.addURL parent called for <url>/fpApplet/AppletDemo.jar
basic: Plugin2ClassLoader.addURL parent called for <url>/fpApplet/FDxSDKPro.jar

basic: Your security settings have blocked an untrusted application from running
basic: exception: Your security settings have blocked an untrusted application from running.
com.sun.deploy.security.BlockedException: Your security settings have blocked an untrusted application from running

I assume, that Applet is blocked because of this and two following lines (Trust for: fpApplet/FDxSDKPro.jar has ended: Thu Jan 01 01:00:00 CET 1970).

I do not know how this can happen if jars are signed? Has anyone had such problems?

Bydefault the JAVA security in version 7 is high, so change the security to medium from control panel.follow the link http://www.java.com/en/download/help/jcp_security.xml
