I've been doing some searching, but haven't found much of this yet. Is it possible to get a commercial SSL cert for perdition without having to use the tomcat Keystore cert first?

If not, how do I set up(if possible) my tomcat SSL cert to work for multiple domain names. For instance, I want to be be able to use ssl on the same server for mailserver.mydomain.com and aliasname.mydomain.com. I would then run the conversion utility to create the cert files for perdition and apply it there. I just need to know what to set in my CSR when using keytool, if I can't easily set up a different cert for perdition by itself.

Does that make sense?

Thanks!!!
