It appears that MemoryUserDatabaseMBean is broken in Tomcat 6 (and probably earlier versions of Tomcat, though I haven't tried them).
I've been playing around with the Tomcat's support for the MX4J HttpAdaptor as described at http://tomcat.apache.org/tomcat-6.0-doc/monitoring.html , and tried using the MemoryUserDatabaseMBean (Users:type=UserDatabase,database=UserDatabase) to edit my tomcat-users.xml file on the fly without restarting Tomcat. Some of its operations sort of work (notably, "save" appears to work properly, and "createGroup", "createUser", and "createRole" do appear to create groups, users, and roles, respectively), but for the most part, the MBean appears to be horribly broken. When I call one of the "create" operations, the role, group, or user does get created (at least, they show up in tomcat-users.xml after I call "save"), but no corresponding RoleMBean, GroupMBean, or UserMBean is registered, so there's no way to assign roles and groups to users after they are created (and a user with no roles is fairly useless). According to their descriptions, the "find" operations are supposed to return MBean names, but instead they return the XML snippets that appear in tomcat-users.xml. The "remove" operations don't work at all. For example, when I try to invoke "removeUser", I get the error "Cannot find method removeUser with this signature." I couldn't find any mention of this in the Tomcat 6 bug database. Should I submit a bug report? -- Rich --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
