Second, you can simply disable the HTTPS because technically having that part working is not critical to understanding how the source code works (and Seam)
Finally, it's highly likely that your HTTPS is not configured correctly. I would first verify that you can see the JBoss AS start page at the root context over HTTPS before trying the application. [ October 07, 2008: Message edited by: Dan Allen ]
Two suggestions to get SSL working. First, make sure you are using JBoss 4.2.2.GA (or better). If you need to get it working on other versions, get it working on that version first, then you can expand your horizon. Second, start with a fresh installation and follow the instructions carefully. If you did, Google because there are many other tutorials available and maybe I am not explaining something right (if you find out what it is, let me know).
