Programmatic Form Based Authentication - jsf-2

Question

I am trying to perform the programmatic form based authentication and it seems that
My web.xml:
<web-app>
<context-param>
<param-name>javax.faces.PROJECT_STAGE</param-name>
<param-value>Development</param-value>
</context-param>
<servlet>
<servlet-name>Faces Servlet</servlet-name>
<servlet-class>javax.faces.webapp.FacesServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>Faces Servlet</servlet-name>
<url-pattern>*.jsf</url-pattern>
</servlet-mapping>
<servlet-mapping>
<servlet-name>Faces Servlet</servlet-name>
<url-pattern>*.xhtml</url-pattern>
</servlet-mapping>
<welcome-file-list>
<welcome-file>confirmauthentication.xhtml</welcome-file>
</welcome-file-list>
<session-config>
<session-timeout>10</session-timeout>
</session-config>
<security-constraint>
<display-name>Authentication Ex Login</display-name>
<web-resource-collection>
<web-resource-name>SecuredArea</web-resource-name>
<url-pattern>/*</url-pattern>
<http-method>GET</http-method>
<http-method>POST</http-method>
</web-resource-collection>
<auth-constraint>
<description/>
<role-name>*</role-name>
</auth-constraint>
</security-constraint>
<login-config>
<auth-method>FORM</auth-method>
<realm-name>mysqldomain</realm-name>
<form-login-config>
<form-login-page>/authentication.xhtml</form-login-page>
<form-error-page>/error.xhtml</form-error-page>
</form-login-config>
</login-config>
<security-role>
<description/>
<role-name>*</role-name>
</security-role>
</web-app>
My jsf page called authentication.xhtml:
<h:form>
<h:panelGrid border="0" columns="2">
<h:outputText value="Username"/>
<h:inputText value="#{beanJSF.userName}" required="true" />
<h:outputText value="Password"/>
<h:inputSecret value="#{beanJSF.password}" required="true" />
<h:commandButton value="Log in" action="#{beanJSF.submit}">
<f:ajax execute="#form" render="#form" />
</h:commandButton>
<h:messages />
</h:panelGrid>
</h:form>
It seems that when I press the “Log in” button, the submit method is not called and I can’t figure out the reason. The server.log doesn’t display anything when I press the button (This message is not displayed “("I am in the login method!!!!!!!!...”).
My ManagedBean:
#URLMappings(mappings={
#URLMapping(id="success", pattern = "/authentication/", viewId = "/confirmauthentication.jsf")})
public class BeanJSF implements Serializable {
private String password;
private String userName;
// User is the Entity
private User loggedUser;
#EJB
UserEJB services;
public String submit() throws IOException {
System.out.println("I am in the login method!!!!!!!! " + getUserName()+ " " + getPassword());
FacesContext context = FacesContext.getCurrentInstance();
ExternalContext externalContext = context.getExternalContext();
HttpServletRequest request = (HttpServletRequest) externalContext.getRequest();
try {
request.login(userName, password);
User user = services.authenticationUser(userName, password);
this.setLoggedUser(user);
return "home?faces-redirect-true";
} catch (ServletException e) {
// Handle unknown username/password in request.login().
context.addMessage(null, new FacesMessage(FacesMessage.SEVERITY_ERROR,"Unknown login", null));
return null;
}
}
public void logout() throws IOException {
ExternalContext externalContext = FacesContext.getCurrentInstance().getExternalContext();
externalContext.invalidateSession();
externalContext.redirect(externalContext.getRequestContextPath() + "/authentication.xhtml");
}
//+ setters and getters for username, password and loggedUser
}
And my EJB is:
#Stateless
public class UserEJB{
#PersistenceContext(unitName = "PyPersistenceUnit")
private EntityManager entityManager;
public UserEJB(){}
#TransactionAttribute(TransactionAttributeType.REQUIRED)
public User authenticationUser(String userName, String password){
try{
User user = entityManager.createNamedQuery(User.FIND_USER,User.class). setParameter("userName", userName).setParameter("password", password).getSingleResult();
return user;
}
catch(NonUniqueResultException ex){
ex.printStackTrace();
return null;
}
catch(NoResultException ex){
ex.printStackTrace();
return null;
}
}

Your bean is not managed by JSF and hence JSF is not able to find the bean anywhere.
Add the JSF bean management annotations to the class.
#ManagedBean
#RequestScoped
public class BeanJSF implements Serializable {
// ...
}
