Hi,
I deploy a .ear on JBOSS.
I have 3 layers : web.war, ejb.jar, dao.jar.
I can reach ejb from web layer using Spring.
But I can't manage to reach dao from ejb !
I wire ejb with dao in the applicationContext.xml of ejb.jar. But no way to reach the dao.
Is there a special thing to do ?
Thanx 4 help.

Please be more specific about your problem. What do you mean by "can't reach"?
Hi Rod,
It's a honnor for me that you answer !
I have this EJB in package busy of my business.jar :
Business the business interface
BusinessHome the Home Interface
BusinessLocal the Remote Interface
BusinessEjb the EJB wich calls BusinessImpl
BusinessImpl the POJO which implements Business
I have this dao in package dao in dao.jar :
IDAO interface
DAO implements IDAO
I wanna wire BusinessImpl to DAO.
Here is applicationContext of ejb.jar :
<bean id="dao" class="dao.DAO"/>
<bean id="businessImpl" class="busy.BusinessImpl">
<property name="dao">
<ref bean="dao"/>
</property>
</bean>
<bean id="businessEjb" class="busy.BusinessEjb">
<property name="business">
<ref bean="businessImpl" />
</property>
</bean>
If I don't wire the EJB to the DAO, it's OK.
But now they are wired and JBOSS says CreateException :

Hi Rod,
It was a stupid mistake from me : I use comma instead of space in ejb.jar Manifest.mf Class-Path=...
My ejb can reach now my dao.
Sorry 4 the disturbance and thanx a lot.
