Here is the ejb-jar file after having describe the relationship behaviour:
<snip>
<relationships>
<ejb-relation>
<ejb-relation-name>Employee-Company</ejb-relation-name>
<ejb-relationship-role>
<ejb-relationship-role-name>Employees-workat-Company</ejb-relationship-role-name>
<multiplicity>Many</multiplicity>
<relationship-role-source>
<ejb-name>employeBean</ejb-name>
</relationship-role-source>
<cmr-field>
<cmr-field-name>company</cmr-field-name>
<cmr-field-type>fr.geomath.intranet.calendrier.ejb.cmp.company.companyLocal</cmr-field-type>
</cmr-field>
</ejb-relationship-role>
<ejb-relationship-role>
<ejb-relationship-role-name>Company-employs-Employees</ejb-relationship-role-name>
<multiplicity>One</multiplicity>
<relationship-role-source>
<ejb-name>employeBean</ejb-name>
</relationship-role-source>
</ejb-relationship-role>
</ejb-relation>
</relationships>
</snip>
As you can see, the relation is made through a company field in the
employeBean and many employees can have only one company.
According to this, there is no need to use a collection to create/maintain
the relationship but JBoss complains that :
<snip>
org.jboss.deployment.DeploymentException: Error in ejb-jar.xml for relation
Employee-Company: cmr-field-type should be java.util.Collection or
java.util.Set but is
fr.geomath.intranet.calendrier.ejb.cmp.company.companyLocal
</snip>
Does JBoss use a Collection even when it will contains only one element ?
Thanks,
