All Implemented Interfaces:

java.io.Serializable

public class PKCS11Exception
extends TokenException

This is the superclass of all checked exceptions used by this package. An exception of this class indicates that a function call to the underlying PKCS#11 module returned a value not equal to CKR_OK. The application can get the returned value by calling getErrorCode(). A return value not equal to CKR_OK is the only reason for such an exception to be thrown. PKCS#11 defines the meaning of an error-code, which may depend on the context in which the error occurs.
