I write two next classes for authentification:
| @(protected)
| @(protected)("authenticator")
| public class AuthenticatorAction implements Authenticator
| {
| @(protected) EntityManager em;
|
| @(protected)(required=false, scope = SESSION)
| private User user;
|
| public boolean authenticate()
| {
| List results = em.createQuery("select u from User u where u.username=
#{identity.username} and u.password=#{identity.password}")
| .getResultList();
|
| if ( results.size()==0 )
| {
| return false;
| }
| else
| {
| user = (User) results.get(0);
| return true;
| }
| }
|
| }
|
| @(protected)
| public interface Authenticator
| {
| boolean authenticate();
| }
|
...and next security mapping in components.xml
| <security:identity authenticate-method="#{authenticator.authenticate}"
| security-rules="#{securityRules}"
| remember-me="true"/>
