got it again,
now my jndi lookup start with "java:global/...."

i only succeeded because there was server log entry "INFO: Portable JNDI names for EJB UserDAOBean .........."

now I can see how missed this topic subject is, cause its all about getting reference to ejb,

anyway, i have recreated this project but now with maven and the problem is back ^^ my ejb is null again
i had to remove <ejb-local-ref> <ejb-ref-name>ejb/UserDAOBean</ejb-ref-name> <local>my.facade.UserDAOLocal</local> </ejb-local-ref> from web.xml

added
(name="UserDAOBean") to @Stateless annotation of my UserDAOBean

so now iam using it like this in JSF Managed Bean
@EJB(beanName="UserDAOBean") UserDAOLocal userDAO;
@Mark Spritzler
i have tried to do as you suggested, as far as i could understand it, but with no luck , and of course i dont know if it still applies to my new(maven) situation

can you explain it in 'simple english', like for an idiot :P
hope i dont ask for too much

Try putting breakpoint in your userdetails and seeing what is null.

You are using j_username in your username field on your form, correct?

Mark

username is correct, i am using login form generated by spring.

but my userDAO is null, and thats the problem

edit : i probably need to use jndi lookup, looking into this right now

eidt 2: got it
1) added in web.xml <ejb-local-ref> <ejb-ref-name>ejb/UserDAOBean</ejb-ref-name> <local>my.facade.UserDAOLocal</local> </ejb-local-ref>
2)
in my UserDetailsService
InitialContext ctx = new InitialContext(); UserDAOLocal ejb = (UserDAOLocal) ctx.lookup("java:comp/env/ejb/UserDAOBean");

still if there is better/more 'pro' way i would like to here it :P

hi, i have created simple CRUD app(beginner here) which is working fine, so now i want to add authentication

after trial of errors i am finally able to successfully deploy my app, but at first login attempt i am receiving :
WARNING: StandardWrapperValve[default]: PWC1406: Servlet.service() for servlet default threw exception java.lang.NullPointerException at my.security.MyUserDetailsService.loadUserByUsername(MyUserDetailsService.java:31)
my UserDetailsService implementation
public class MyUserDetailsService implements UserDetailsService{ @EJB UserDAOLocal userDAO; my.domain.User userEntity; User user; //org.springframework.security.core.userdetails.User @Override public UserDetails loadUserByUsername(String string) throws UsernameNotFoundException, DataAccessException { userEntity = userDAO.getUser(string); // warning caused by this if(user == null) throw new UsernameNotFoundException("Username not found"); Collection<GrantedAuthority> authorities = new ArrayList<GrantedAuthority>(); authorities.add(new GrantedAuthorityImpl(userEntity.getAuthority().getAuthority())); user = new User(userEntity.getUsername(),userEntity.getPassword(), userEntity.getEnabled(), userEntity.getEnabled(), userEntity.getEnabled(), userEntity.getEnabled(), authorities ); return user; } }
part of applicationContext-security.xml
<beans:bean id = "userDetailsService" class = "my.security.MyUserDetailsService" /> <authentication-manager> <authentication-provider user-service-ref = "userDetailsService" > <password-encoder hash="md5"/> </authentication-provider> </authentication-manager>

is it possible to use @EJB annotation in UserDetailsService, same way i am using it in JSF Managed Bean ?

thank you very much , its working, haha now when i know the answer its seams logical :P

it was automatically generated by netBeans
@Entity @Table(name = "treemenu") public class TreeMenu implements Serializable { private static final long serialVersionUID = 1L; @Id @GeneratedValue(strategy = GenerationType.IDENTITY) @Basic(optional = false) @Column(name = "itemIndex") private Integer itemIndex; @Basic(optional = false) @Column(name = "title") private String title; @OneToMany(mappedBy = "treeMenu") private Collection<TreeMenu> treeMenuCollection; @JoinColumn(name = "parentIndex", referencedColumnName = "itemIndex") @ManyToOne private TreeMenu treeMenu;

hi, i am working on recreating tree from database table,



what i need to do is to select all items where parentIndex is null

so in mysql i can do : SELECT * FROM `treemenu` WHERE parentIndex IS NULL

how should query look like in jpa to get same results ?

"SELECT t FROM TreeMenu t WHERE t.parentIndex IS NULL" gives me 'unknown state or association field [parentIndex]'

touche
shame i have wasted 2 days on that issue

Hi,
i am complete beginner if it comes to JPA/EJB so i dont know, if i will be able to explain myself correctly but here we go:

here is my database


and two automatically generated by netBeans classes (based on that database)
@Entity @Table(name = "users") public class User implements Serializable { private static final long serialVersionUID = 1L; @Id @Basic(optional = false) @Column(name = "username") private String username; @Basic(optional = false) @Column(name = "password") private String password; @Basic(optional = false) @Column(name = "enabled") private boolean enabled; @OneToOne(cascade = CascadeType.ALL, mappedBy = "user") private Authority authority;

@Entity @Table(name = "authorities") public class Authority implements Serializable { private static final long serialVersionUID = 1L; @Id @Basic(optional = false) @Column(name = "username") private String username; @Basic(optional = false) @Column(name = "authority") private String authority; @JoinColumn(name = "username", referencedColumnName = "username", insertable = false, updatable = false) @OneToOne(optional = false) private User user;

and in the third class UserDAOBean i am doing createUser updateUser deleteUser ... etc.
i am able to successfully persist() or remove() user but i can not update(merge ?) username(PK)

Exception Description: The attribute [username] of class [my.domain.User] is mapped to a primary key column in the database. Updates are not allowed.

any ideas ?
