Class LoginBean

java.lang.Object

bradleyross.j2ee.beans.LoginBean

All Implemented Interfaces:

Serializable

public class LoginBean
extends Object
implements Serializable

Sample bean for login information.

Uses the annotations ManagedBean and RequestScoped.

It appears that I can't use the implicit objects for JSF expression language (param, request, response, etc.) in the ManagedBean annotations.

Field Detail

userName

private String userName

User name.

The annotation ManagedProperty apparently controls actions by the JSF handler with regard to variables.

password

private String password

User login password.

sessionBean

private SessionProperties sessionBean

I believe that the ManagedProperty annotation in this method will cause the sessionProperties bean to be created at the same time as the loginBean.

The ManagedProperty annotation appears to work when referencing other managed beans but not when referencing implicit objects.

Constructor Detail

LoginBean

public LoginBean()

This constructor reads the HTTP request parameter name and places it in the user name field of the form.

I had previously tried using #{param} in the ManagedBean annotation for a property, but it didn't seem to work. Some messages on the web indicated that it worked, but it may be implementation dependent.

The constructor will set the userName property to the value of the "name" parameter if the parameter is present.

Method Detail

getUserName

public String getUserName()

setUserName

public void setUserName(String value)

getPassword

public String getPassword()

setPassword

public void setPassword(String value)

authorized

public String authorized()

Determines whether the combination of user name and user password represents a valid user.

In this case, the method accepts any login attempt using "password" for the password. In a real application, a more complicated algorithm would be used.

Returns:

"login" if properties are valid, otherwise "error"

getList

public String getList()

Diagnostic routine listing session, application, and request attributes.

Returns:
