You need to generate a keystore for SSL to work and then modify your server.xml file to tell JBoss/Tomcat where that keystore is.
If you look at chapter 8 of the JBoss Guide (assuming you are using JBoss 4.0) -
Toward the end of the chapter (section 8.7) it tells you how to set up a sample keystore and get SSL to start.
Hopefully that will get you started.
Hello; thank you for your reply. Of course we aren't doing anything with Tomcat. The chapter you mention talks about setting up a keystore for pushing a certificate out at clients who wish to connect to your secure website; we're having problems pulling a certificate from a secure server to which we're attempting to connect.
