The 3.0 Getting Started guide has examples in both Jetty and Tomcat of how to set up multiple connectors (one SSL the other not). You could even set up multiple SSL connectors, one requiring client certificate the other not.
I have a similar problem. I am using JBoss 3.0.4 with Tomcat and try to get Client Certificates working.
Server Certificates are working fine. But if I set clientAuth = "true" nothing changes. I can still access the web pages although I do not have any client certificate installed in my browser.
What do I get wrong?
