What is the solution for following exception. Pls help me out.
Exception in thread "main" java.lang.SecurityException: class "org.mozilla.jss.C ryptoManager$UserCertConflictException"'s signer information does not match sign er information of other classes in the same package at java.lang.ClassLoader.checkCerts(Unknown Source) at java.lang.ClassLoader.defineClass(Unknown Source) at java.security.SecureClassLoader.defineClass(Unknown Source) at java.net.URLClassLoader.defineClass(Unknown Source) at java.net.URLClassLoader.access$100(Unknown Source) at java.net.URLClassLoader$1.run(Unknown Source) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) at sun.misc.Launcher$AppClassLoader.loadClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) at java.lang.ClassLoader.loadClassInternal(Unknown Source) at Pruebas.main(Pruebas.java:18)
This happens when classes belonging to the same package are loaded from different JAR files, and those JAR files have signatures signed with different certificates or, perhaps more often, at least one is signed and one or more others are not. This includes classes loaded from directories.
