Mike,
below is the top of FactoryBean.java. the first EJB created in the chain.
-------------------------------------------
import javax.ejb.*;
import org.ejbutils.uid.*;
import org.ejbutils.context.*;
public abstract class FactoryBean implements EntityBean {
EntityContext entityContext;
public java.lang.String ejbCreate(java.lang.String name) throws
CreateException {
setName(name);
String objectId;
try {
objectId = UIDDispenser.getDispenser().getNextId();
} catch (UIDDispenserException e) {
throw new EJBException(e.toString());
}
this.setId(objectId);
return objectId;
}
public void ejbPostCreate(java.lang.String name) throws CreateException {
}
...
-------------------------------------------
and here is the start of ProcessBean.java the second created. It has a cmr
field pointing
to the primary key of factory.
-------------------------------------------
import java.util.*;
import javax.rmi.*;
import javax.ejb.*;
import javax.naming.*;
import org.ejbutils.uid.*;
import org.ejbutils.context.*;
public abstract class ProcessBean implements EntityBean {
EntityContext entityContext;
public String ejbCreate(String factory, String name) throws
CreateException {
setName(name);
String objectId;
try {
objectId = UIDDispenser.getDispenser().getNextId();
} catch (UIDDispenserException e) {
throw new EJBException(e.toString());
}
setId(objectId);
return objectId;
}
public void ejbPostCreate(String factory, String name) throws
CreateException {
try {
Context ctx = new InitialContext();
FactoryLocalHome flhome =
(FactoryLocalHome)ctx.lookup("java:comp/env/ejb/Factory");
FactoryLocal fl = flhome.findByName(factory);
this.setFactory(fl);
} catch (NamingException e) {
throw new EJBException(e.toString());
} catch (FinderException e) {
throw new CreateException(e.toString());
}
}
...
-------------------------------------------
Did not declare the cmr fields in the ejb-jar.xml file, nor the jboss.xml
file.
All the ejb creates use the UIDispenser from Emmanuel Sciara (many thanks,
and everyone that contibuted to the solution). The process bean sets the cmr
field pointing to its factory that is looked up by name, in the
ejbPostCreate method.
Many thanks
Daniel

Daniel,
I'm not sure I completely understand the situation. Maybe if you sent
some Java code snippets I could take a stab at it. Like just the
"ejbCreate" and "ejbPostCreate" methods for "Variable" or "Factory"
which ever one is calling the setter method.
