Hi,
I tried to replicate your class hierarchy with the simple-stateless
example that comes with OpenEJB, and I wasn't able to reproduce your
problem. I've popped my code up http://www.jrg.me.uk/examples.zip -
perhaps you could have a look and let me know if my class hierarchy
matches yours, or if there is anything I've missed in trying to
reproduce the problem? (Or if you have some code you can share that I
can try running that would be great too).
Could you also let me know which version of OpenEJB you're using, I've
assumed you're using the released 3.0, and I've tested with both that
and the latest from trunk.
Thanks
Jon

Hi,
I try to use OpenEJB to run unit tests within a Maven project. Part of the
code of this project is generated by AndroMDA MDA framework.
For each EJB session bean, four classes are generated, to separate code
generated once from code generated at each Maven install, to share code
between local and remote EJB, etc ...
For example for an EmployeeService local EJB I have the following classes :
One implementation class, generated once, where I can write business code :
- class EmployeeServiceBean extends EmployeeServiceBase implements
EmployeeServiceLocal
One abstract base class, generated everytime I run mvn install :
- abstract class EmployeeServiceBase implements EmployeeService
And two interfaces, generated everytime too :
- @javax.ejb.Local interface EmployeeServiceLocal extends EmployeeService
- interface EmployeeService
All public methods for a stateless EJB are declared in EmployeeServiceLocal
interface, the other interface is supposed to define getter and setter
methods for attributes of stateful session beans.
I also have a ejb-jar.xml file with EJB defined as following :
<session>
<ejb-name>EmployeeServiceBean</ejb-name>
<local>t4.core.employee.EmployeeServiceLocal</local>
<ejb-class>t4.core.employee.EmployeeServiceBean</ejb-class>
<session-type>Stateless</session-type>
<transaction-type>Container</transaction-type>
</session>
In a TestNG test class, I have the following code looking for the EJB
session bean from its JNDI name :
EmployeeServiceLocal employeeService =
(EmployeeServiceLocal)
getInitialContext().lookup("EmployeeServiceBean/Local");
OpenEJB retrieves the EJB but I have a ClassCastException. I expected the
EJB to be EmployeeServiceLocal typed (as it is the case in ejb-jar.xml), but
it is EmployeeService typed ! It looks like OpenEJB doesn't retrieve
interface of the implementation class, but interface from the base class. Is
it something intended or is it a bug ?
Thanks in advance for your help ;)
And congratulations for the good job made on OpenEJB. I tried to use other
embedded containers (JBoss Embedded, Glassfish embedded, EJB3Unit, ...) and
met so many bugs I could not make them work. I am not far to succeed with
Open EJB !
