I’m trying to create a relationship between Visitor and Country entity beans. The relationship is using a map table VisitorInterestCountry to form a n:m relationship. When I try to deploy I’m getting the error

org.jboss.deployment.DeploymentException: Role ‘country-has-visitor’ on Entity Bean ‘Country’ : CMP field for key not found: field name=’visitorId’

Will MyEclipse XDoclet handle a n:m relationship, and if so; how do we implement this?
————————————————–

From Visitor.java

 

XDoclet-based CMP 2.x entity bean.  This class must be declared

 * public abstract because the concrete class will

 * be implemented by the CMP providers tooling.

 * 

 * To generate EJB related classes using XDoclet:

 *

 *                      - Add Standard EJB module to XDoclet project properties

 *                      - Customize XDoclet configuration

 *                      - Run XDoclet

 * 

 * Below are the xdoclet-related tags needed for this EJB.

 *

 * @ejb.bean name="Visitor"

 *           display-name="Visitor"

 *           description="Visitor EJB"

 *           jndi-name="ejb/VisitorHome"

 *           local-jndi-name = "ejb/VisitorLocalHome"

 *           type="CMP"

 *           cmp-version="2.x"

 *           view-type="local"

 *           primkey-field = "visitorId"

 * 

 * @ejb.pk class="java.lang.Integer" generate="false"

 * 

 * @ejb:util generate="physical"

 * 

 * @ejb:persistence table-name = "Visitor"

 * 

 * @ejb.value-object name = "Visitor"

 *                                  match="*"

 * 

 * @jboss.persistence create-table="true"

 *                                  remove-table="true"

 *

If any users had thoughts on this it would be appreciated if you could help out.

We found that Xdoclet was not correctly generating the COMP_NAME value for our session beans. We had to manually change this and then we were able to get everything to work. We may have an erroneous XDoclet configuration — not sure, but this workaround will do.
