exception trying to load entity with idClass - 'id column not in any table'

Project: Hibernate Entity Manager
Issue Type: Bug
Components: EntityManager
Reporter: Adam Hardy
Hibernate EntityManager won't map an id-class for an entity. I have ust one entity with an inner class as the idClass.
Hibernate refuses to load the entity, throwing the following exception (see further down).
I am using hibernate-annotations-3.3.0ga and hibernate-entitymanager-3.3.1ga.

I'm using Derby, Hypersonic, H2 or postgresql. It seems to be database-independent.
This is the generated SQL:
select habitatspe0_.habitatId as habitatId0_0_, habitatspe0_.speciesId as speciesId0_0_ from DEV.HABITAT_SPECIES_LINK habitatspe0_ where habitatspe0_.habitatId=? and habitatspe0_.speciesId=?

[Hibernate-JIRA] Created: (ANN-685) Hibernate does not honor @Column(name=...) annotation with IdClass
by Steve Devore (JIRA)
Hibernate does not honor @Column(name=...) annotation with IdClass
------------------------------------------------------------------
Key: ANN-685
URL: http://opensource.atlassian.com/projects/hibernate/browse/ANN-685
Project: Hibernate Annotations
Issue Type: Bug
Affects Versions: 3.2.1
Environment: Hibernate 3.2.1, JBoss 4.0.4
Reporter: Steve Devore
When an Entity uses an IdClass, any query will fail fails because it is using the name of the attribute instead of the one indicated by the @Column annotation. It fails because it is looking for the annotations of the IdClass instead of the main class.
Please see the following example:
The IdClass is defined as follows:
public class DomainAdminId implements Serializable {
private String domainName;
private String adminUser;
public DomainAdminId() {
}
public DomainAdminId(String domainName, String adminUser) {
this.domainName = domainName;
this.adminUser = adminUser;
}
public String getDomainName() {
return domainName;
}
public void setDomainName(String domainName) {
this.domainName = domainName;
}
public String getAdminUser() {
return adminUser;
}
public void setAdminUser(String adminUser) {
this.adminUser = adminUser;
}
public boolean equals(Object o) {
return ((o instanceof DomainAdminId) &&
domainName.equals(((DomainAdminId)o).getDomainName()) &&
adminUser.equals(((DomainAdminId)o).getAdminUser()));
}
public int hashCode() {
return (domainName+adminUser).hashCode();
}
}
And the following Entity using that idClass:
@Entity
@Table(name="domainadmin")
@IdClass(DomainAdminId.class)
@NamedQueries( {
@NamedQuery(name = "DomainAdmin.test", query = "SELECT d FROM DomainAdmin d")
)
public class DomainAdmin implements Serializable {
@Id
@Column(name="domain_name")
private String domainName;
@Id
@Column(name="adminuser")
private String adminUser;
public DomainAdmin() {
}
public String getDomainName() {
return domainName;
}
public void setDomainName(String domainName) {
this.domainName = domainName;
}
public String getAdminUser() {
return adminUser;
}
public void setAdminUser(String adminUser) {
this.adminUser = adminUser;
}
}
When executing the DomainAdmin.test Named Query I got this error:
could not execute query [select domainadmi0_.adminUser as adminUser1_, domainadmi0_.domainName as domainName1_ from domainadmin domainadmi0_]
com.mysql.jdbc.exceptions.MySQLSyntaxErrorException: Unknown column 'domainadmi0_.domainName' in 'field list'
In effect, as indicated in the source, the column name is "domain_name" and not "domainName".
The same apply for the other column: adminUser (that should instead be "adminuser"),
Workaround:
If the @Column annotation is put on the IdClass it will work sucessfully. However, this should not be necessary.

Tutorial Project to illustrate use of Hibernate using Annotations and additionally provide Unit Testing for Support for PostgreSQL UUID data type
-------------------------------------------------------------------------------------------------------------------------------------------------
Key: HHH-4093
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-4093
Project: Hibernate Core
Issue Type: Improvement
Components: documentation
Environment: Hibernate 3.5.0 (Trunk), Postgresql 8.3 or greater
Reporter: David Driscoll
Attachments: hibernate-tutorials-annotations.zip
Ran into issue HH-3579, and needed support for Uuid type in Postgresql.
I have create patches for HH-3579, so that Hibernate now support the Uuid type in Postgresql.
I created this project (attached as zip) to be able to Unit Test these patches in a web application environment using Unit Tests via JUnit 4.
Here is an excerpt from the readme file in this project:
This project was created for the main purpose of unit testing a Hibernate enhancement (HH-3579)
that added uuid sql types to hibernate. Specifically, for unit testing against Postgresql 8.3 or greater
which allows uuid data types. Additionally, it demonstrates how to use Hibernate with Annotations.
This tutorial implements a basic web application using Hibernate 3.5 (trunk), Spring Framework 3.0 (trunk), Spring's MVC, and Atomikos Transaction Manager 3.5.5.

[Hibernate-JIRA] Created: (HHH-3590) Having @version in Parent causes wrong HQL update when updating subclass in Joined Subclass Inheritance Strategy.
by Rachit (JIRA)
Having @version in Parent causes wrong HQL update when updating subclass in Joined Subclass Inheritance Strategy.
-----------------------------------------------------------------------------------------------------------------
Key: HHH-3590
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3590
Project: Hibernate Core
Issue Type: Bug
Components: query-hql
Affects Versions: 3.3.1
Environment: Java 1.5 , Oracle 10g , Hibernate 3.3.1.GA
Reporter: Rachit
Priority: Blocker
A very simple joined subclass strategy implemented.
2 classes: Employee(parent/superclass) and Person( child/subclass)
Employee has @Version defined on column ROW_VERSION and Person extends Employee using Joined Inheritance Strategy. Person has PERSON_ID as PK and Employee has EMPLOYEE_ID as PK. I also have @PrimaryKeyJoinColumn(name = "PERSON_ID", referencedColumnName = "EMPLOYEE_ID") for obvious reason.
Now if I update any attribute in Child class i.e Person.setVIPFlag("Y") , hibernate fires an update query on Parent entity with wrong column name in hql. In this case the query would be "update EMPLOYEE set ROW_VERSION=? where PERSON_ID=? and ROW_VERSION=?". This query fails as EMPLOYEE does not have PERSON_ID.
The moment I remove @Version annotation from Parent(Employee) class, there is no update ( as expected ) and hence no error, but this is not an acceptable solution.
Thanking in anticipation.

[Hibernate-JIRA] Created: (HHH-2146) NullpointerException in DefaultDeleteEventListener.deleteTransientEntity
by Martin Kartumovich (JIRA)
NullpointerException in DefaultDeleteEventListener.deleteTransientEntity
------------------------------------------------------------------------
Key: HHH-2146
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2146
Project: Hibernate3
Type: Bug
Versions: 3.2.0.cr5
Environment: Hibernate 3.2.0cr5, Oracle10g
Reporter: Martin Kartumovich
Priority: Blocker
The following setup leads to a NPE in DefaultDeleteEventListener.deleteTransientEntity:
Tables A, B
Table V_A_B that is an M-N-Connection between A and B.
Pojo for A has a Set of V_A_Bs.
Pojo for B has a Set of V_A_Bs.
Pojo C that has Sets of As and Bs.
Cascades: all, delete-orphan
-Create a new A and add a new V_A_B to its Set, that references to an existing B.
-Delete B.
-SaveOrUpdate Pojo C.
In Hibernate 3.1.3 this works fine.
In 3.2.0cr4+cr5 the removal of B results into an cascading removal of the never persisted V_A_B in the Set of B instead of ignoring it.
This leads to an incorrect state where deleteTransientEntity is called with transientEnties=null.
When now calling transientEnties.contains(...) the NPE is thrown.
