Why is JBossWeb throwing 'javax.net.ssl.SSLException: No available certificate or key corresponds to the SSL cipher suites which are enabled.' when I try to enable SSL?

2011-08-25 08:58:00,117 ERROR [org.apache.coyote.http11.Http11Protocol] (main) Error initializing endpoint
java.io.IOException: SSL configuration is invalid due to No available certificate or key corresponds to the SSL cipher suites which are enabled.
