Security Exception from Java stand-alone program on Linux

Question

Hi All,
I am getting the following exception while running a Java stand-alone program on Linux.
The stand-alone program internally calls the JCE (Java Cryptography Extension) library for Encryption of data.
Does anybody have the solution for this error?
Is there any Security policy modification to be made for the same?

No security modification is normally required. I can't be sure but it looks to me like the jar file containing the package javax.crypto.e has not been signed by Sun. If you are writing your own provider then you would do well to look at reply #7 of http://forum.java.sun.com/thread.jspa?threadID=5222038 .
