How to get username j_security_check as bean property

In my managed bean, I want to get the username j_security_check

that auths to the LDAP server as a property of the bean.

Basically, I want to output the username from

<input type="text" name="j_username" />

      

after it is sent and everything is complete and use it in the following:

@Override
public String getName() {
    return getId();
}

      

How to use

FacesContext.getExternalContext().getUserPrincipal();

      

to get the username as a bean property?

This is full bean support in case you need to know what it does. I used to manually force the user to enter the username in the textbox, now I want to stop this and pull the username automatically.

//@Named("user")
@SessionScoped
public class UserBean implements Serializable, Principal {

    private static final long serialVersionUID = 1L;
    @NotNull(message = "The username can not be blank")
    @Size(min = 6, max = 12, message = "Please enter a valid username (6-12 characters)")
//@Pattern(regexp = "[a-zA-Z0-9_]", message = "Please enter a valid username consiting of only characters that are from the alphabet or are numeric ")
//@Pattern(regexp = "(a-z)(A-Z)(0-9))", message = "Please enter a valid username consiting of only characters that are from the alphabet or are numeric ")
    private String id;

    public String getId() {
        return id;
    }

    public void setId(String newValue) {
        id = newValue;
    }
    private String fileText;

    @NotNull(message = "You must select a file to upload")
    public String getFileText() {
        return fileText;
    }

    public void setFileText(String fileText) {
        this.fileText = fileText;
    }

    /**
     * public void getName(HttpServletRequest req, HttpServletResponse res)
     * throws ServletException, java.io.IOException { id = req.getRemoteUser();
     * }
     */
    @Override
    public String getName() {
        return getId();
    }
    /*
     * @Override
     *
     * public String request.remoteUser() { return getId();
     *
     * }
     * .
     */
}

Initialize it in @PostConstruct

.

private String username;

@PostConstruct
public void init() {
    username = FacesContext.getCurrentInstance().getExternalContext().getRemoteUser();
}

      

Or, if you only need it during processing, submit the form, just get it in the action method.



Note that getRemoteUser()

basically returns the same as getUserPrincipal().getName()

.


Unrelated to the specific issue: This kind of bean should not be session scope, but a view or conversation scope is available instead. Also, it doesn't have to implement the interface Principal

. It doesn't make any sense.
