Relating stateless session beans
Hi everyone!
After some time spent without problems now I am in a dead end. Googling and previous posts didn't help, so here i am seeking for an hint.
I have a stateless session bean name it UserManagerPB that uses OJB to persist customers' data, with following deploy descriptor entry
--->ejb-jar.xml
<ejb-name>UserManagerPB</ejb-name>
com.wapa.interprj.storage.UserManagerPBHome
com.wapa.interprj.storage.UserManagerPB
<local-home>com.wapa.interprj.storage.UserManagerPBLocalHome</local-home>
com.wapa.interprj.storage.UserManagerPBLocal
<ejb-class>com.wapa.interprj.storage.UserManagerPBSession</ejb-class>
<session-type>Stateless</session-type>
<transaction-type>Container</transaction-type>
-----------
---->jboss.xml
<ejb-name>UserManagerPB</ejb-name>
<jndi-name>com.wapa.interprj.storage.UserManagerPB</jndi-name>
<local-jndi-name>UserManagerPBLocal</local-jndi-name>
-----------
The business methods have @ejb:interface-method attribute as for example:
------>UserManagerPB.getUser()
/**
* @ejb:interface-method
*
*
*/
public PersistentUser getUser(String username)
-----
I can work with a remote client accessing this bean smoothly but what i really need to do is calling methods as the one above from another bean.
I have created another stateless bean called UserAccess, with the following attributes:
* @ejb.bean name="UserAccess"
* jndi-name="UserAccess"
* type="Stateless"
* transaction-type="Container"
*
*
* *
* @ejb.ejb-ref ejb-name="UserManagerPB"
* view-type="remote"
*
* @jboss.ejb-ref-jndi ref-name="UserManagerPB"
jndi-name="UserManagerPB"
*
that generate these entries
------>ejb-jar.xml
<ejb-name>UserAccess</ejb-name>
com.wapa.interprj.storage.UserAccessHome
com.wapa.interprj.storage.UserAccess
<local-home>com.wapa.interprj.storage.UserAccessLocalHome</local-home>
com.wapa.interprj.storage.UserAccessLocal
<ejb-class>com.wapa.interprj.storage.UserAccessSession</ejb-class>
<session-type>Stateless</session-type>
<transaction-type>Container</transaction-type>
<ejb-ref >
<ejb-ref-name>ejb/UserManagerPB</ejb-ref-name>
<ejb-ref-type>Session</ejb-ref-type>
com.wapa.interprj.storage.UserManagerPBHome
com.wapa.interprj.storage.UserManagerPB
<ejb-link>UserManagerPB</ejb-link>
</ejb-ref>
-----------
----->jboss.xml
<ejb-name>UserAccess</ejb-name>
<jndi-name>UserAccess</jndi-name>
<local-jndi-name>UserAccessLocal</local-jndi-name>
<ejb-local-ref>
<ejb-ref-name>ejb/UserManagerPB</ejb-ref-name>
<jndi-name>UserManagerPB</jndi-name>
</ejb-local-ref>

What i'm trying to do actually is accessing methods from UserManagerPB
within UserAccess, doing something like
UserManagerPB userManager = UserManagerPBUtil.getHome().create();
PersistentUser p = userManager.getUser(username);
The problem is that i can't deploy the modules since i get this exception
---------->

My original plan was to use the @home-method attribute for the methods of UserManagerPB to be accessed by UserAccess. Since i was getting the very same error I thought i was wrong with something there so i moved to the remote interface since I had used this before successfully but now i'm pretty stuck.
Any help would be pretty appreciated guys...
Thanks everyone,
