Hi, I am getting an error as "NoClassDefFoundError" when trying to create instance of Cipher class. Cipher rsaCipher= Cipher.getInstance("RSA/PKCS1/PKCS1") When I stop/start the iPlanet server, for the first time it gives me the error "error: APPLOGIC-caught_exception: Caught Exception: java.lang.ClassCastException: java.lang.ExceptionInInitializerError" and when I try to execute it again it gives me the error "error: APPLOGIC-caught_exception: Caught Exception: java.lang.ClassCastException: java.lang.NoClassDefFoundError". Can anybody help me in this. It is very urgent. Thanks in advance. Regards,    More>>
