Today, I reloaded JRE, JVM. After starting JBoss, I log in to http: // localhost: 8089 / web-console / console, found that the function buttons on the left didn't have it, prompting could not find Org.jboss.console.navtree.AppletBrowser NOT FOUND, find Sun's Java Forum a post on this problem solution: i Just Came Across The Same Problem. I fixed it by activating the sun java plug in - Previously the MS JVM WAS ACTIVE, I think it is. It turned out to be a browser problem. I have encountered a similar problem because the function buttons on the left are applet. After reloading the JDK, my browser Gosurf can't load Java Plug in, you can use IE to log in!
Depressed for a long time, finally got!
