Now i have successfully signed the jar file and export the certificate file.On client side i imported that xxx.cer into $(jre)/lib/security/cacerts keystore.
However when i changed the java.policy using policytool it reported:
Warning: Unable to open Keystore: file://C:/jdk1.3.1/jre/lib/security/cacerts
Warning: A public key for alias 'midas' does not exist.

I know the JRE needs the public key to ensure the signed applet's correctness.But how can i make such a public key?
