Jar Exception in java

I am getting java.lang.SecurityException and java.util.jar.JarException , when trying to use the cryptix-jce-provider.jar . It say开发者_JAVA百科s that the JAR has unsigned entries - cryptix/jce/ElGamalKey.class

how can i resolve this problem ?

Refer to the cryptix website. The certificate used to sign cryptix jar files have expired. Hence the warning. Workarounds are in this discussion.
