Help Requested --> Yep, it's a verifier message!

[Darryl A. J. Staflund]

Hi all,
Related to my previous post, I was wondering if someone could tell me why I get the following error when running 'verifier' against my J2EE application.
The error (actually errors, but I think they have a common root) is as follows:

Test Name : tests.ejb.entity.cmp2.CmrFieldsAbstract
Test Assertion : EJB 2.0 Spec 9.4.1, the cmp and cmr fields should be virtual fields only
Test Description : Unexpected error in verifier, check for problems related to: [ java.lang.NullPointerException ]

Test Name : tests.ejb.entity.cmp2.CmrFieldAccessor
Test Assertion : EJB 2.0 Spec 9.4.1, cmr field accessors must bear the name of the field, first letter uppercased and prefixed with get and set
Test Description : Error : Cannot find accessor [ get_DevelopmentResourceEJB_resource ] method for [ _DevelopmentResourceEJB_resource ] field
For [ ResourceEJB ]
Error : [ {0} ] field accessor method has the wrong return type [ {1} ]
Error : Cannot find accessor [ get_ProductionResourceEJB_resource ] method for [ _ProductionResourceEJB_resource ] field
For [ ResourceEJB ]
Error : [ {0} ] field accessor method has the wrong return type [ {1} ]

Test Name : tests.ejb.entity.cmp2.CmrFieldAccessorModifiers
Test Assertion : EJB 2.0 Spec 9.4.1, cmr field accessors methods must be abstract, public or protected
Test Description : Unexpected error in verifier, check for problems related to: [ java.lang.NullPointerException ]

The section of my ejb-jar.xml deployment descriptor that sets up the CMR relationship is as follows:

<!--Resource-DevelopmentResource (1-1, uni-directional.)-->
<ejb-relation>
<ejb-relation-name>Resource-DevelopmentResource</ejb-relation-name>
<ejb-relationship-role>
<ejb-relationship-role-name>Resource-exemplifies-DevelopmentResource</ejb-relationship-role-name>

</cmr-field>
</ejb-relationship-role>
</ejb-relation>

My DevelopmentResourceEJB class is defined as follows:

package ca.talonline.applications.taladmin.domain.development.developmentresource;
//TAL Admin classes.
import ca.talonline.applications.taladmin.domain.resource.*;
import ca.talonline.applications.taladmin.domain.validation.error.*;

return (primaryKey);
}

And finally, the section of the ejb-jar.xml deployment descriptor responsible for defining the DevelopmentResourceEJB entity bean is as follows:

I really can't see a problem with my code and am hoping that a pair of fresh eyes can point out the trouble.
Thanks,
Darryl

PS: I am using J2EE 1.4 beta's verifier.
