More value-object novice problems.... I'm trying to get relationship
(aggregate) support to work so I added the ejb.value-object clause to
the comment below:
/**
* Returns related Resource
*
* @return related
com.sprint.fmsD.genequip.ejb.interfaces.ResourceLocal
*
* @ejb.interface-method
* view-type="local"
*
* @ejb.relation
* name="port-resource"
* role-name="port-has-resource"
* target-ejb="Resource"
* target-role-name="resource-has-port"
*
* @ejb.value-object
* aggregate="com.sprint.fmsD.genequip.ejb.interfaces.ResourceValue
* aggregate-name="OwnerResourceValue"
* match="*"
*
* @weblogic.column-map
* foreign-key-column="RSRC_ID"
* key-column="RSRC_ID"
*/
public abstract ResourceLocal getResource();
I modeled this after what I observed in the sample project and what I
could understand from reading the help file at
http://cvs.sourceforge.net/cgi-bin/viewcvs.cgi/*checkout*/xdoclet/xdoclet/core/docs/valueobject.html?rev=HEAD&content-type=text/html.
Apparently, I'm not getting it right. When I run my ejbdoclet task, I
get the following error:
Running <valueobject/>
Generating Value Object class:
'com.sprint.fmsD.genequip.ejb.entity.PortBean-->

Your help in interpreting the error message and/or debugging my
value-object tag would be greatly appreciated!
