Handling SSLHandshakeException in Tomcat 5.5.17

Hi,

How do I handle this exception, when the user clicks "Cancel" upon SSL Client authentication when prompted for a certificate.

javax.net.ssl.SSLHandshakeException: null cert chain

Tomcat throws this exception, but I would like to catch it and redirect the user to a proper error page. The full stack trace is as follows:

2007-05-14 10:35:36 org.apache.tomcat.util.net.jsse.JSSE14Support synchronousHandshake
