Hello rtrancoso. I am afraid, that JBoss doesn't support this functionality - as I described, the only thing to secure the RMI was, that the client had to have server certificate in its trust store. I also browsed over many JBoss tutorials and forums and nothing helped me in this way. Some informations can be found here: http://itextdocs.lowagie.com/techtips/ssl/ - RMI over SSL and here: http://answers.suziana.com/2006/12/13/security-jaasjboss-rmi-over-ssl-mut... So good luck with solving this problem. We have moved to WebShere, where this security is supported. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4064869#...
