exception trying to load entity with idClass - 'id column not in any table'
---------------------------------------------------------------------------
Key: EJB-343
URL: http://opensource.atlassian.com/projects/hibernate/browse/EJB-343
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.

This is the entity code:

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-4642) Unexpected results when an entity with non-flushed changes is changed from read-only to modifiable
by Gail Badner (JIRA)
Unexpected results when an entity with non-flushed changes is changed from read-only to modifiable
--------------------------------------------------------------------------------------------------
Key: HHH-4642
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-4642
Project: Hibernate Core
Issue Type: Bug
Components: core
Affects Versions: 3.5.0-Beta-2, 3.5.0.Beta-1
Reporter: Gail Badner
Assignee: Gail Badner
When an entity is changed from being read-only to modifiable, its snapshot is created from its current state (in the session), not its persistent state (in the DB).
This can cause unexpected results when:
- an entity had non-flushed changes when it was set to read-only, or
- an entity's state (in the session) was changed after being made read-only.
If no other changes are made to the entity after being made modifiable, Hibernate will not detect that the entity is dirty, and those changes will not be pushed to the DB. If other changes are made, Hibernate will detect that the entity is dirty, and the newer changes will be persisted, but the older changes may not be.
