[jboss-user] [EJB 3.0] - Re: hibernate and inheritance
I found a possible explanation to this problem. It seem's the discriminant is'n't used when requesting by a one-to-many in an subclass. So a way to make hibernate consider the hierarchy is to force control on the Discriminator column. With annotations, @Where should be used. @Where(clause=POI_TYPE='B') and @Where(clause=POI_TYPE='C') But in my example, I really don't understand where I have to place this clauses. Any help ?

[jboss-user] [EJB 3.0] - hibernate and inheritance
Hello,
I've a problem with requests on sublasses of a class tree (Entity beans). I got
a org.hibernate.WrongClassException when trying to access data with a oneToMany
relation.
My architecture is:
A B C
| @Entity
| @Table(name = A)
| @Inheritance(strategy = InheritanceType.SINGLE_TABLE)
| @DiscriminatorColumn(name = DTYPE, discriminatorType =
DiscriminatorType.STRING)
| @DiscriminatorValue(A_TYPE)
| public class A implements java.io.Serializable {
|
| private Long id;
| ...
| }
|
| @Entity
| @DiscriminatorValue(B_TYPE)
| public class B extends A {
|
| // Associations
| private CollectionObj objSet = new ArrayListObj();
|
| @OneToMany(mappedBy = A)
| public CollectionReview getObjSet() {
| return objSet;
| }
|
| public void setObjSet(CollectionObj objSet) {
| this.objSet = objSet;
| }
| }
|
| @Entity
| @DiscriminatorValue(C_TYPE)
| public class C extends B {
|...
| }
|
|
And Obj is defined like:
| @Entity
| @Table(name = OBJ)
| public class Obj {
| private B value;
|
| @ManyToOne
| @JoinColumn(name=A_ID)
| public AppPOI getValue() {
| return value;
| }
|
| public void setValue(B value) {
| this.value = value;
| }
|
| }
|
When I create a new Obj and associate it to a B Entity it works. (correctly
added to the DB, good ID pointing from OBJ to a A like entry)
Now when I try to access using this request:
SELECT obj FROM Obj obj WHERE obj.value.id=44549450
It gives me that error message:
| org.hibernate.WrongClassException: Object with id: 44549450 was not of the
specified subclass: C (Discriminator: B_TYPE)
|
I'm using using jboss 4.0.5 with seam and hibernate updated to version 3.2.5ga
Thanks for your help, I couldn't find an answer to my problem with the search
function of this forum, I've passed so many times reading it at this point...
Paulin

[jboss-user] [JBoss Seam] - Re: Double authentication in different parts of a site
Hello,
I have a other problem with my authentication. My idea was to extend
RuleBasedIdentity and so create ECIdentity class.
Here is my program:
component.xml
security:identity
| class=ecidentity
| authenticate-method=#{authenticator.authenticate}
| security-rules=#{securityRules}/
|
ECIdentity.java
@Name(ecidentity)
| @Scope(SESSION)
| @Intercept(InterceptionType.AFTER_RESTORE_VIEW)
| @Startup
| public class ECIdentity extends RuleBasedIdentity {
|
| String role = null;
|
|
| public String login() {
|
|
| System.err.println(First login);
|
| return super.login();
|
| }
| }
|
Authenticator.java
@Name(authenticator)
| public class Authenticator {
| @Logger Log log;
|
| @In(value=ecidentity) ECIdentity ecIdentity;
|
| @In EntityManager entityManager;
|
| @In(#{messages['ErrorOnLogin']}) private String LoginError;
|
| public boolean authenticate() {
|
| System.err.println(First authenticate);
| System.err.println(Username =
+ECIdentity.instance().getUsername());
|
| try {
| String hashedPassword = Util.createPasswordHash(MD5,
Util.BASE64_ENCODING, null, null,ECIdentity.instance().getPassword());
|
| Mb member = (Mb) entityManager.createQuery(
| from Mb where login = :username and passwd =
:password)
| .setParameter(username,
ECIdentity.instance().getUsername())
| .setParameter(password, hashedPassword)
| .getSingleResult();
|
| return true;
| }
| catch (NoResultException ex) {
| FacesMessages.instance().add(LoginError);
| return false;
| }
| }
| }
|
And when I submit (the action performed is #{ecidentity.login} ), I get the
following error message in the console:
15:46:53,967 ERROR [STDERR] First login
| 15:46:54,386 ERROR [STDERR] First authenticate
| 15:46:54,387 ERROR [STDERR] Username = null

|
|
|
|
|
I have no idea why my ECIdentity object isn't reacheable.
Thanks for your help.
Best regards
PC

[jboss-user] [JBoss Seam] - Double authentication in different parts of a site
Hello, I ask for your help on an authentication procedure with seam. Users are in different tables (User and ExtraUser), I want make the difference beetween those two kind of users. So the login page have to be separated etc. My problem is the Identity component configured in component.xml. It refers to only 1 method and I would like to use separated Identity based components depending on the part of the application used (eg. User or ExtraUser login -and then- home page). Is that possible ? If yes please you tell me, I absolutely found nothing like that in the forum archives...
