Hello,
Again me for another problem !!!
During the creation of the bean (Home.Create), I have a ClassCastException :
java.lang.Long !!
My bean has a primary key of the type Long !
I use JBoss and JAWS (CMP) with an Access Database.
It sounds that the ejb-jar file is right.
The error occur during a call to : myHome.create();
I know it call the method ejbCreate() successfully, but after I have the
crash
I have the following corresponding methods :
-----------------------------------------------------------------
ODATAServicesRegistryHome
> ODATAServicesRegistryBI Create()
> ODATAServicesRegistryBI findByPrimaryKey(Long ...)
ODATAServicesRegistryBean
- Long ejbCreate()
- public Long PrimaryKey;
ejb-jar.xml
---------------
<primkey-field>PrimaryKey</primkey-field>
<primary-key-class>java.lang.Long</primary-key-class>
<cmp-field><field-name>PrimaryKey</field-name></cmp-field>
The DB file
------------------
I have create a database file with a table named ODATAServicesRegistry and 2
fields :
- PrimaryKey : Numeric
- ServicesState : Text
And the JBoss log
---------------------------
[Default] jBoss 2.0 FINAL Started
[ODATAServicesRegistry] [ODATAServicesRegistry] - ejbCreate() - begin
[ODATAServicesRegistry] [ODATAServicesRegistry] - ejbCreate() - PrimaryKey =
1
[ODATAServicesRegistry] [ODATAServicesRegistry] - ejbCreate() - end

I hope that someone can help me, because after several days I cannot find
why I have this error !!
(Also I cannot directly debug in JBoss because we use VA 3.5 !!)
Thanks a lot for your help
Christophe
