Project: EJB 3.0
Issue Type: Bug
Affects Versions: EJB 3.0 RC9 - FD
Environment: jboss.4.0.4GA EJB 3.0 RC9-FD JDK 1.5.0_08
Reporter: Haohua xie
use the ejb3 tutorial of joininheritance as the template . i did not chanage any code of
Pet.java Cat.java Dog.java.i just add some functions to PetDao and PetDAOBean
i write a entity, Decorate, referring to Pet. i can insert a entity of Decorate into the
database but when i try to get out the entities of Decorate from the database, some
exception happens.
i also try the codes on jboss.4.0.4GA EJB 3.0 RC8-FD JDK 1.5.0_08. it works well and i got
the result:

New subject: [JBoss JIRA] Updated: (EJBTHREE-722) can't get a entity with entity relation to a superclass of a joined-inheritance
[ http://jira.jboss.com/jira/browse/EJBTHREE-722?page=all ]
Haohua xie updated EJBTHREE-722:
--------------------------------
Attachment: joininheritance.rar
this is the code which can run well on RC8 but fail on RC9
can't get a entity with entity relation to a superclass of a
joined-inheritance
--------------------------------------------------------------------------------
Key: EJBTHREE-722
URL: http://jira.jboss.com/jira/browse/EJBTHREE-722
Project: EJB 3.0
Issue Type: Bug
Affects Versions: EJB 3.0 RC9 - FD
Environment: jboss.4.0.4GA EJB 3.0 RC9-FD JDK 1.5.0_08
Reporter: Haohua xie
Attachments: joininheritance.rar
use the ejb3 tutorial of joininheritance as the template . i did not chanage any code of
Pet.java Cat.java Dog.java.i just add some functions to PetDao and PetDAOBean
i write a entity, Decorate, referring to Pet. i can insert a entity of Decorate into the
database but when i try to get out the entities of Decorate from the database, some
exception happens.
i also try the codes on jboss.4.0.4GA EJB 3.0 RC8-FD JDK 1.5.0_08. it works well and i
got the result:
