We have written a midlet that works well with 5140i and when we use new NFC SDK (of course after recompiled classes for NFC) do we get error messages.
This is what happends:

Program starts when. When I touch personal ID tag it hangs:

"No Class Def Found Error java/lang/NoClassDefFoundError
com/sun/midp/io/j2me/nfc/Protocol: Cannot create class in system package"

Some knows about this?
