## javax.microedition.pki
Class CertificateException

    java.lang.Object
      java.lang.Throwable
          java.lang.Exception
              java.io.IOException
                  javax.microedition.pki.CertificateException

    @TransactionType(value=NOT_SUPPORTED)
    public class CertificateException

extends IOException

The `CertificateException` encapsulates an error that occurred while a `Certificate` is being used. If multiple errors are found within a `Certificate` the more significant error should be reported in the exception.

Direct instances of this exception class are not bound to any context and can be passed between contexts without any restrictions. Objects created and returned by the methods of this class are owned by the caller. In particular, a call to the `Throwable.getMessage()` returns a String instance bound to the owner context of the caller.

See Runtime Environment Specification for the Java Card Platform, Connected Edition, chapter 7 for details regarding transfer of ownership.

Since:
  MIDP 2.0
