                Well, when i log all is ok; infact i have this message:
                10:00:49,841 INFO [STDOUT] Username: ML password: ML applicationPolicy: client-login
                10:00:49,851 INFO [STDOUT] Login in LoginFilter ok

                But as you can see when i go to the servlet from the filter, the principal is null:

                10:00:49,851 INFO [STDOUT] Tento login con username: [ML] e password: [ML] Il principal è nullo? null


                Well, the processDefinitions.jsp page can call the EJB, but if i click on a link and i want to go to the processStart.jsp page, i have the error principal=null..... why does this happen? How can i solve it?

                  Did you add a jboss.xml for your EJBs with a security domain entry ?
                  If not, JBoss won't know which Security Manager to instantiate for authenticating and authorizing the EJB invocation.

                  Your jboss.xml file should look something like this :

                  <?xml version="1.0" encoding="UTF-8"?>

                  <!DOCTYPE jboss PUBLIC
                  "-//JBoss//DTD JBOSS 3.0//EN"
                  "http://www.jboss.org/j2ee/dtd/jboss_3_0.dtd">

                    As you can see the security-domain are equals..... i'm becoming crazy to solve this error.... have you any ideas?

                      Gianluca Brigandi Newbie

                      Ok, could be that the LoginModule de.danet.an.staffmgmt.jbossx.StaffMemberLoginModule you are using is not building an authenticated Subject the way JBoss is expecting it.

                      I'd suggest you to change the debug level of the org.jboss.security.auth.spi package to TRACE. With this you will be able to see more details about whats happening in the Login Module. Would be usefull if you make a followup with it.

                      Another thing:
                      In your web tier if you do a 'request.getUserPrincipal()' what is the result ?
                      Do you get 'null' or a valid Principal ?
                      If you get 'null' here don't expect the Security Manager in your EJB tier, to know which is the username to be used when invoking the login module.

                      Regards.
                      Gianluca.

                        HI; one question... are you italian o do you speak italian? If so the next time we can speack into italian because my english is tooo poor.
                        Well... when i log by calling 'request.getUserPrincipal() the first time i have ML; then the de.danet.an.staffmgmt.jbossx.StaffMemberLoginModule creates a right Princiapl and i go to the Servlet, when i arrive to the servlet i have this principal

                        Tento login con username: [ML] e password: [ML] Il principal è nullo? null


                        As you can see even if username and password are what i have inserted.... the Principal is null and i don't know why; moreover:

                        I'd suggest you to change the debug level of the org.jboss.security.auth.spi package to TRACE. With this you will be able to see more details about whats happening in the Login Module. Would be usefull if you make a followup with it.


                        How can i do this? I'm newbie in JBoss. Thanks for your help..

                          Add the following to your $JBOSS_HOME/server/default/conf/log4j.xml file :

                           <appender name="SECURITYLOG" class="org.apache.log4j.FileAppender">
                           <param name="File" value="${jboss.server.home.dir}/log/security.log"/>
                           <param name="Append" value="false"/>
                          
                           <layout class="org.apache.log4j.PatternLayout">
                           <param name="ConversionPattern" value="%d %-5p [%c] %m%n"/>
                           </layout>
                           </appender>
                          
                           <category name="org.jboss.security.auth">
                           <priority value="TRACE" class="org.jboss.logging.XLevel"/>
                           <appender-ref ref="SECURITYLOG"/>
                           </category>
                          


                          This will log in a file called security.log trace messages for the org.jboss.security.auth package.

                              My God... is it really so difficult to handle JAAS in JBoss?

                                Another thing (by hoping that someone answers to me)... if i insert this url patterns: /*... when i do the login with the login.jsp page, i remain always in this page and i have non message form the console; instead if i don't put this URL, at least the first called to the EJB i can do.... when i call it a second time , i have the error prinsipal = null (if i do request.getUserPrincipal() ); instead if i do SecurityAssociation.getPrincipal, i have ML..... is it normal?

                                  From the log you are posting, seems like the StaffMemberLoginModule is not being executed by the org.jboss.security.auth.spi.ProxyLoginModule.
                                  You should see traces at least like the following :

                                  [org.jboss.security.auth.spi.AbstractServerLoginModule] initialize
                                  [org.jboss.security.auth.spi.AbstractServerLoginModule] login

                                  Is the StaffMemberLoginModule class in your classpath ?

                                    Hi; thanks again; yes.. this class is in my classpath because the first time i do the login even if the principal is ML, by using this class i can have StaffManagementRole_0.... i can see the first page that uses the EJB and the EJB is called with no problem; then i have some href that go to another page where the EJB is called... but here the principal is null and i have the exception... i don't understand why.
