com.sun.crypto.provider.RSAChiper is not a subclass of xjava.security.Ciphe

I have installed Tertio Provident

This was developed with java and at the beginning I hve to connect to a server. I was not able to connect. On connection this error occurs:"Could not connect to the Provident Service Activation Server,

class configured for Cipher: com.sun.crypto.provider.RSACipher is not a subclass of xjava.security.Cipher"

This error occurs only on my machine which has installed windows 2K and jdk 1.5

Do you know what I have to do to solve this problem?

Thank you

Marco
