This week's book giveaway is in the OCAJP forum. We're giving away four copies of OCA Java SE 8 Programmer I Study Guide 1Z0-808 and have Jeanne Boyarsky & Scott Selikoff on-line! See this thread for details.
As discussed in the startguide.pdf (section 2.2.3 Security Service) of JBoss 4.0.3, i made the changes (basically uncommented code) in jboss-web.xml and web.xml in WEB-INF directory. The JMX-console was working fine earlier but after making the changes, I'm getting "cannot perform access control without an authenticated principal" exception when I click on jmx-console. The document said "If you've configured everything correctly and re-deployed the application, the next time you try to access the JMX Console, JBoss will ask you for a name and password." Please help
