    Am I missing a trick?

    Paul Anderson Newbie


      I am running jboss 4.04 and have implemented form based authentication using the DatabaseServerLoginModule. Everything is working fine. However, once my user has logged in I need to be able to access the user's username and password. I have checked through lots of the posts on here and seen other people requesting how to get at the j_username and j_password fields... The general reply seemed to be that they should use the ExtendedFormAuthenticator as per the corresponding Wiki page. I have followed the instructions of the Wiki page to the letter and have not been able to get it to work... I have added a context.xml file to my webapp WEB-INF directory (which didn't work) and so also modified the context.xml file under the jbossweb-tomcat55.sar directory... and of course bounced jboss.

      WebApp context.xml

      <!-- Add the ExtendedFormAuthenticator to get access to the username/password/exception -->
      <Context cookies="true" crossContext="true">
       <Valve className="org.jboss.web.tomcat.security.ExtendedFormAuthenticator"
       includePassword="true" />

      Ammended tomcat context.xml

      <!-- The contents of this file will be loaded for each web application -->
      <Context cookies="true" crossContext="true">
       <!-- Session persistence is disable by default. To enable for all web
       apps set the pathname to a non-empty value:
       <Manager pathname="SESSIONS.ser" />
       To enable session persistence for a single web app, add a
       <Manager pathname="" />
       <!-- Install an InstanceListener to handle the establishment of the run-as
       role for servlet init/destroy events.
       <!-- Add the ExtendedFormAuthenticator to all applications by default -->
       <Valve className="org.jboss.web.tomcat.security.ExtendedFormAuthenticator"
       includePassword="true" />

      I was then trying to access the j_username and j_password information in my JSP in the following manner as all the posts I read seemed to suggest that the username and password were cached in the session when you used the ExtendedFormAuthenticator:

       String username = (String) session.getAttribute("j_username");
       String password = (String) session.getAttribute("j_password");
       <p>Username: <%=username%></p>
       <p>Password: <%=password%></p>

      All i get is 'null' and 'null' for the username and password. What have I missed?

      I have also tried programatically trying to access the information and have had some degree of success but not exactly what I am looking for.

      Here is the code that has enabled me to see the user's username and the roles that the user belongs to.... but there is no password.... maybe I am missing something here?

      //Get the Authenticated Subject
      Subject subject = (Subject) PolicyContext.getContext("javax.security.auth.Subject.container");
      Set principals = subject.getPrincipals(Principal.class);
      Iterator iter = principals.iterator();
       Principal p = (Principal)iter.next();
       if(p instanceof SimpleGroup) {
       SimpleGroup sg = (SimpleGroup)p;
       %> <p>Group:<%=sg.getName()%></p>
       Enumeration en = sg.members();
       while(en.hasMoreElements()) {
       String role = en.nextElement().toString();
       if(role != null) { %>
       } else {
       %><p>Something Else:<%=p%></p><%

      Any help, pointers, sample code would be greatly appreciated as I really need to try and get this sorted as I need the username and password within my webapp for something.

      Kind Regards,

          Hey Paul,

          Accessing the Subject (like you have done below) is great for getting the username principal and role principals, but I do not think you can get the password. So your best bet is to get the valve working.

          Verify that the valve has been added to your web app's pipeline. This is visible by viewing the mbean details of your web app's deployment in the jmx-console.

            hi j2ee_junkie,

            Are you able to offer any further assistance?
            I am not exactly sure what I am looking for in the jmx-console... it's a little confusing. I can see there are some links under jboss.web that contain the word ExtendedFormAuthenticator and also my webapp name "AMI"

            The links are:

            host=localhost,name=ExtendedFormAuthenticator,path=/,type=Valve host=localhost,name=ExtendedFormAuthenticator,path=/AMI,seq=1,type=Valve

            There are a few more but these don't look relevant. I'm guessing that the top link is down to me adding the ExtendedFormAuthenticator in the tomcat context.xml and the 2 links below that are down to me adding a context.xml with the same valve in my webapp dir?

            If I click on either of these I get a "JMX MBean View" and a form with lots of customisable values in it. What do I do now? Am I looking at the right thing?

              Sorry if I was too vague. You would be looking for a mbean under jboss.web that is something like

              Look for the valveObjectNames attribute of this mbean. You should see a list of all the valves added to this applications context pipeline. So ExtendedFormAuthenticator valve should be there.

              If this valve is there, the next step would be to up the logging to TRACE for this logger and see what is happening during the request.

                One thing I failed to mention before is that the use of this valve is only to put these (i.e. j_username, and j_password) parameters in the session scope if a.) they were passed in as form parameters to the login form
                b.) if the user was forwarded to the login error page.

                I just realized that this is probably not what you are looking for. Let me know and I will advise.

                Again sorry for not noticing this earlier, cgriffith

                  Ok, I found what you suggested to look for and there were 4 links there.


                  So, it definitely looks like the context.xml with the ExtendedFormAuthenticator is getting setup.... but why isn't it working!!!

                  How do I up the logging for this Valve then?

                  Just before I do up the logging, can you sanity check the very basic method I was using to check for j_username and j_password in the session... the code example was in my first post. I think as long as the vales are being set then the code should work, but this has been driving me crazy so you know how you get sometimes... it's like "did I leave the oven on" !!!


                  The only link I could find which resembled your example was as follows:


                  When I click on this I can see nothing to do with Valves at all....

                    Anil Saldanha Master

                    Add the following to your log4j.xml

                     <category name="org.jboss.web.tomcat.security">
                     <priority value="TRACE" class="org.jboss.logging.XLevel"/>

                    Now in your server.log, you should see log entries under the "FormAuthValve" name (We had a logger copy/paste error)

                      Hmmmmm, the plot thinkens junkie...

                      I just uncommented the request dumper in the tomcat server.xml file and when I check the server.log I can not see ANY mention of ExtendedFormAuthenticator.... it only shows FormAuthenticator. Snippet below...

                        Thank you for you help.... unfortunately though I think it is not working correctly as I get a series of errors when starting my server to do with LOG4J. I think this is a known bug... it happens on a straight out the box download of jboss 4.04... which is what I am running.

                        The error reads:

                          Hi junkie,

                          Sorry... didn't see your post with the 'a' and 'b' parts...

                          So, are you saying then that the ExtendedFormAuthenticator will ONLY put j_username and j_password in the session if the user is redirected to the login error page? What is the point of that?

                          That's not how I interpretted it... I thought it put j_username and j_password into the session regardless of whether the login attempt was successful or not. I thought the only difference was that if the login is not successful then the exception is made accessible and placed into the session so that you can display an appropriate reason for the login failure.

                          Let me just clarify again.....

                          I have a valid user, who has logged in using Form Authentication and the DatabaseServerLoginModule. Is there a way to get that user's USERNAME and PASSWORD as I need to use them within my webapp?

                            See my comments in my last post. The ExtendedFormAuthenticator is not what I think you want to use. To demonstrate that, I am looking at your log output that shows you ('pander') successfully logging in. As I mentioned, the valve does not put the username (and password) in session if login was successful.

                            I missed that point when I first tried to help you. I think what you want is a way to access these things once a user is logged in successfully, correct?

                              This is starting to drive me crazy now, big time!


                              Here's the state of play.... I now have both the ExtendedFormAuthenticator and the FormAuthValve defined in my apps context.xml and according to the JMX console they both seem to be loaded and configured correctly.... and yet.... STILL "null" and "null" when I try and access the username and password values in a JSP (within my protected web content i.e. after logging in) using the method below:

                              String username = (String) session.getAttribute("j_username");
                              String password = (String) session.getAttribute("j_password");
                              <p>Username: <%=username%></p>
                              <p>Password: <%=password%></p>

                              Guys, it is really beyond me that this is not better documented somewhere on this site... I cannot believe that I am the first person that needs the username and password after successfully loggin in !!!

                              junkie, you obviously didn't understand what I was looking for to begin with so that's fine, but hopefully you do now, and anil your comment about using the FormAuthValve seemed to make sense when I saw the code... but neither Valves seem to be working... I can't get the TRACE working anil because of the Log4J problem....

                                Hi guys,

                                I don't think this is the intended TRACE that anil wanted me to setup, but it may be useful in trying to diagnose the problem...

                                Here is a section of the server.log from the login form, a successful login and then a redirect to index.jsp (my landing page once logged in).

                                As you can see, the FormAuthValve does seem to be active, but j_username seems to be null which is a little worrying...

                                  Things here are starting to pile up. As already noted, the ExtendedFormAuthenticator puts the j_username (and possible j_password) in the session on the way to your login form or on the way to your error page. Thus if you successfully log in the first time, you will not have these values in you session.

                                  That said, I think you need something that will allow you to get the username and password after a user has successfully logged in. Which you confirmed. The FormAuthValve should work the way you expect it to. However there are other ways to do this that require more work. Let me know if you are interested.

                                  At this point, I suggest you verify that the FormAuthValve is in your application's pipeline. And get Log4j working at TRACE level for this valve.

                                  as far as your comment...

                                  Guys, it is really beyond me that this is not better documented somewhere on this site... I cannot believe that I am the first person that needs the username and password after successfully loggin in !!!

                                  is concerned. I do not think this could be documented any better. The fact that you are having problems to me means that there is some obscure detail that we are missing. Something that is not related to how to get this working. In any case, that is what we are trying to discover.

                                  let us know when you have more to offer, chris griffith
