          • 2. Re: how to get user's password value after success authenticate?
            nathan dennis Expert

            well you know what the problem is... the value isnt there in the bean. says so right there in the stack...

             

            try

             

            <h:commandButton id="login" action="#{identity.login}"   value="Login"

                                     type="submit"  /> 

             

            i doubt its getting there without using the submit option. There are some things that changed in JSF2 might want to take a look at the docs and maybe glance at a migration guide to get you up to speed.

              thanks nathan dennis !!!!

               

              but  the code still run to exception...

               

              ============================

              System.out.println(credentials.getUsername());

              ============================

              the credentials.getUsername() can be output correctly.

               

               

               

              but the code below still run to Exception.

              ============================

              System.out.println(((PasswordCredential) credentials.getCredential()).getValue());

              ============================

               

              i want to get password from credentials.getCredential()

               

              thanks everyone very much!!!

                may be credentials was auto set null  after seam-security authenticated???

                  nathan dennis Expert

                  thats not it.. i just tested it... this works

                   

                  System.out.println( ((PasswordCredential) credentials.getCredential()).getValue());

                   

                  you arent getting the value to the bean.. check the jsf again. something is up with your xhtml

                    nathan dennis Expert

                    why are you using

                    redisplay="true"?

                    http://docs.oracle.com/javaee/6/javaserverfaces/2.1/docs/vdldocs/facelets/h/inputSecret.html

                    Flag indicating that any existing value in this field should be rendered when the form is created. Because this is a potential security risk, password values are not displayed by default.

                     

                    i doubt this is what you want unless you are trying to do something with ajax... which according to your code you arent.

                      i cut the redisplay attribute , and the error still exist.

                       

                      and i cut the project to a very simple example to show the error.

                        you need to take a serious look at your pom.xml.

                         

                        from glancing at the project.. i would follow the seam doc on the configuration of the authenticator ... seam-bean.xml

                        <beans xmlns="http://java.sun.com/xml/ns/javaee"

                           xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

                           xmlns:s="urn:java:ee"

                           xmlns:security="urn:java:org.jboss.seam.security"

                           xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://jboss.org/schema/cdi/beans_1_0.xsd">     

                         

                           <security:IdentityImpl>

                              <s:modifies/>

                                  <security:authenticatorName>simpleAuthenticator</security:authenticatorName>

                           </security:IdentityImpl>

                           

                        </beans>

                         

                        get rid of the @Override

                        i also see you referencing identity without ever moving any sort of role into that.. you might want one at some point..

                         

                                setStatus(AuthenticationStatus.SUCCESS);
                                setUser(new SimpleUser("demo"));
                                identity.addRole("user", "USERS", "user");

                         

                         

                        but seriously.. you pom is all messed up.. you are using some versions of stuff that probably wont work. there is no repo info in there. I cant really tell what you have going on because this project will not compile with this build script.

                          thanks nathan dennis.

                           

                          sorry !!!! my code is so in a mess.

                           

                          so i use official example "security-authorization" in seam-3.1.0.Final and modified a little to show the problem.

                           

                          1. i modifed the method in PrivilegedActions.java:

                          ============================

                          public void doSomethingRestricted() {

                                  System.out.println("print username and password:===========================");

                                  System.out.println(credentials.getUsername());

                                 

                                  System.out.println(((PasswordCredential)(credentials.getCredential())).getValue());

                                  System.out.println("print username and password:---------------------------");

                                  //messages.info("doSomethingRestricted() invoked");

                              }

                          ============================

                           

                           

                          2.cut @Override and modifed home.xhtml to add a <h:inputSecret> field.

                           

                           

                          3.called privilegedActions.doSomethingRestricted method by this commandButton:

                          <h:commandButton value="print password on console()" action="#{privilegedActions.doSomethingRestricted}"/>

                           

                           

                          the code [System.out.println(((PasswordCredential)(credentials.getCredential())).getValue());] still run to Exception.

                                   If you are using credentials.username and credentials.password seam will provide you to get the username and password by this to retreive the logged in username and password :

                             

                                 identity.getusername();

                                 identity.getpassword();

                             

                                 * Here is the sample of code which may help you out :

                                Hi Haisheng !!!                  In your bean you can declare as :                                  @In              Identity identity;              and directly set the values in the setters for example :                 xxxx.setusername(identity.getusername());                  Regards ,  Bhanu Prakash

                                  Credentials is @RequestScoped, not @SessionScoped.

                                   

                                  You might want to store your username and password in a @SessionScoped bean after login success, in order to retreive them later.
