    Subject: Acess to certificate extensions in X.509 certificates?

We're looking at using X.509 certificates in our application and want to
use extensions.

Looking through the JDK1.2 java.security.cert.Certificate and
java.security.cert.X509Certificate javadocs there does not seem to be
any obvious way to get an enumeration or collection of the extensions,
despite there being a java.security.cert.X509Extension interface.

Is the accepted method for gaining access to extensions to get the
encoded certificate and interpret the DER encoding in the application?
