[iaik-jce] Problems with DESKeyGenerator

[Conturbia Riccardo <s75918@dilbert.polito.it>]

Hello,
I'm using iaik_jce_full_ssl_applet.jar version 2.0 (I think...) and I
have a strange problem... the compiler doesn't complain at all, but at
runtime I have an exception:

Exception occurred during event dispatching:
java.lang.NoClassDefFoundError: iaik/security/cipher/DESKeyGenerator
        at ProvaCifra.action(Compiled Code)
        at java.awt.Component.handleEvent(Compiled Code)
        at java.awt.Component.postEvent(Compiled Code)
        at java.awt.Component.postEvent(Compiled Code)
        at java.awt.Component.dispatchEventImpl(Compiled Code)
        at java.awt.Component.dispatchEvent(Compiled Code)
        at java.awt.EventDispatchThread.run(Compiled Code)

What does it mean?

I need this library for my thesis.... :)

Thank you very much...
