How use IdentityManager JpaIdentityStore

[mailojahandrea]

hi, I'm new here, I greet you.
My problem is with identity management because I can not understand the documentation (15.4 Identity Manager). Do you have a working example and easy to show so I can understand?
I'm used to log in using the configuration in components.xml 

<securuty:identity authenticate-method="#{authenticator.authenticate}"/>

...
Thank you for your availability. Greetings to all.
Andrea

Identity manager and jpaIdentityStore are different concepts.
You can customize a identity manager authentication method.
if you use jpaIdentityStore it will not authentica user with the authenticator method.
(authenticator class generated default by seam-gen)

Instead of using JpaIdentityStore , (you don't have to user JpaIdentityStore) .You can use Session scoped Entities.

So what you say but I can not understand. I also tried to use the Observer as in Seamspace, but nothing! Sicutro dsa show that you have a simple example to understand? Thanks

Ok here is a simple classes used for authentication , user and user role Entities
Lets start first with authentication class.
first define your class authentication class in components.xml (which is default with seam-gen or jboss tools  generated project)

In componentes.xml you should have this line

<security:identity authenticate-method="#{authenticator.authenticate}" remember-me="true"/>

And two classes UserAccount.java and UserRole.java

UserAccount.java

package org.domain.test.entity;

import java.io.Serializable;
import java.util.ArrayList;
import java.util.List;
import javax.persistence.CascadeType;
import javax.persistence.Entity;
import javax.persistence.FetchType;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.GeneratedValue;
import javax.persistence.JoinColumn;
import javax.persistence.JoinTable;
import javax.persistence.ManyToMany;
import javax.persistence.SequenceGenerator;


@Entity
public class UserAccount implements Serializable
{
     @Id @GeneratedValue
       private Integer userId;
       private String username;       
       private String passwordHash;

       @ManyToMany(fetch=FetchType.LAZY ,cascade = CascadeType.PERSIST)
       @JoinTable(name="ROLE_ACCOUNT",
       joinColumns= {@JoinColumn (name="userId", referencedColumnName="userId")},
       inverseJoinColumns= {@JoinColumn (name="roleId", referencedColumnName="roleId")})
       private List<UserRole> roles = new ArrayList<UserRole>();       
       public Integer getUserId() { return userId; }
       public void setUserId(Integer userId) { this.userId = userId; }
       public String getUsername() { return username; }
       public void setUsername(String username) { this.username = username; }
       public String getPasswordHash() { return passwordHash; }
       public void setPasswordHash(String passwordHash) { this.passwordHash = passwordHash; }
       public void setRoles(List<UserRole> roles) {
          this.roles = roles;
       }
       public List<UserRole> getRoles() {
          return roles;
       }
}

And UserRole.java

package org.domain.test.entity;

import java.io.Serializable;
import java.util.ArrayList;
import java.util.List;

import javax.persistence.Entity;
import javax.persistence.FetchType;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.GeneratedValue;
import javax.persistence.ManyToMany;
import javax.persistence.SequenceGenerator;
import org.hibernate.validator.NotEmpty;
import org.jboss.seam.annotations.Name;

@Entity
@Name("userRole")
public class UserRole implements Serializable
{
     @Id@GeneratedValue
     private Integer roleId;
     @NotEmpty
     private String rolename;     
     @ManyToMany(fetch=FetchType.LAZY, mappedBy="roles")
     private List<UserAccount> roles = new ArrayList<UserAccount>();
     public Integer getRoleId(){ return roleId; }     
     public void setRoleId(Integer roleId) { this.roleId = roleId; }     
     public String getRolename(){ return rolename; }     
     public void setRolename(String rolename){ this.rolename = rolename; }
     public void setRoles(List<UserAccount> roles){
          this.roles = roles;
     }
     public List<UserAccount> getRoles(){
          return roles;
     }
}

And last class which is using for authenctication. (as i said default java class generated with seam-gen)

package org.domain.test.session;


import javax.faces.application.FacesMessage;
import javax.faces.application.FacesMessage.Severity;
import javax.persistence.EntityManager;
import javax.persistence.NoResultException;

import org.domain.test.entity.UserAccount;
import org.domain.test.entity.UserRole;
import org.jboss.seam.ScopeType;
import org.jboss.seam.annotations.In;
import org.jboss.seam.annotations.Name;
import org.jboss.seam.annotations.Out;
import org.jboss.seam.faces.FacesMessages;
import org.jboss.seam.security.Credentials;
import org.jboss.seam.security.Identity;


@Name("authenticator")
public class Authenticator
{
     @In Credentials credentials;
     @In Identity identity;
     @In FacesMessages facesMessages;
     @In EntityManager entityManager;
     @Out(scope=ScopeType.SESSION)
     UserAccount user;
     
     public boolean authenticate(){
          try{
               user = (UserAccount)entityManager.createQuery("from UserAccount where " +
                                                                      "username = :username and passwordHash = :password")
                                                       .setParameter("username", credentials.getUsername())
                                                       .setParameter("password", credentials.getPassword())
                                                       .getSingleResult();
               if (user.getRoles() != null){
                    for (UserRole mr : user.getRoles()){
                         identity.addRole(mr.getRolename());
                    }
                    
                    return true;
               }
               else {
                    return false;
               }
          }
          catch (NoResultException ex){
               System.out.println("kullanici yok");
               facesMessages.addFromResourceBundle(FacesMessage.SEVERITY_ERROR,"org.jboss.seam.NoResult");
               return false;
          }
     }

}

As you see we did not used any jpaIdentityStore annotations like @user @role etc...
Hope this examples would work for you.
if you have any questions please don't hesistate , and please don't forget to rate :)
