Certificate Loading Issue

Question

I have developed one applet and I am finding a strange behavior.

This is for implemented security based application which build in GWT, Hibernate and Spring.

The applet is mainly accessing browser certificates and using it for encryption and decryption of data.

It is working fine on all the system but I don't know one client machine I am finding a strange behavior.

When I login in Internet Explorer. The applet loading stops at following point and then closes down automatically.

Error in applet console saying:

basic: Added progress listener: sun.plugin.util.GrayBoxPainter$GrayBoxProgressListener@337d0f

basic: Plugin2ClassLoader.addURL parent called for http://phil.etenders.in/securityApplet.jar security: Blacklist revocation check is enabled security: Trusted libraries list check is enabled network: Cache entry found [url: http://phil.etenders.in/securityApplet.jar, version: null] prevalidated=false/0

Removed Blacklist Revocation Check and Trusted Library check but there is no impact. (They are passing through well),

If I open any sample applet from http://csis.pace.edu/~bergin/Java/applets.htm it stops on following line

    basic: Plugin2ClassLoader.isTrustedByPolicy called 
    basic: Plugin2ClassLoader.isTrustedByPolicy returns false 

Behaviour on all three browsers.

1. Firefox and Chrome : Does not load at all.
2. IE : First time does not load when hit refresh it loads.

Let me know if more detail needed. Refer source code from here.
