Am trying to create 1-to-many bidirectional relation between File and Type entity. The
relation is, one File has one Type while one Type has many Files. Can someone plz help
me with this am stuck :-(
This is how I try:
File:
/**
| * @ejb.interface-method
| * view-type="local"
| *
| * @ejb.persistence
| * column-name = "typeid"
| *
| * @ejb.relation
| * name="File-Type"
| * role-name="File-has-Type"
| */
| public abstract TypeLocal getType();
| /**
| * @ejb.interface-method
| * view-type="local"
| */
| public abstract void setType(TypeLocal type);
Type:
public abstract void setName(String name);
| /**
| * @ejb.interface-method
| * view-type="local"
| *
| * @ejb.relation
| * name="File-Type"
| * role-name="Type-has-many-File"
| * target-ejb="File"
| * target-multiple="yes"
| * target-role-name="File-has-Type"
| *
| * @jboss.relation
| * related-pk-field="id"
| * fk-column="typeid"
| */
| public abstract java.util.Collection getFiles();
| /**
| * @ejb.interface-method
| * view-type="local"
| */
| public abstract void setFiles(java.util.Collection files);
Descripter:
<ejb-relation >
| <ejb-relation-name>File-Type</ejb-relation-name>
|
| <ejb-relationship-role >
| <ejb-relationship-role-name>File-has-Type</ejb-relationship-role-name>
| <multiplicity>Many</multiplicity>
| <relationship-role-source >
| <ejb-name>File</ejb-name>
| </relationship-role-source>
| <cmr-field >
| <cmr-field-name>type</cmr-field-name>
| </cmr-field>
| </ejb-relationship-role>
|
| <ejb-relationship-role >
|
<ejb-relationship-role-name>Type-has-many-File</ejb-relationship-role-name>
| <multiplicity>One</multiplicity>
| <relationship-role-source >
| <ejb-name>Type</ejb-name>
| </relationship-role-source>
| <cmr-field >
| <cmr-field-name>files</cmr-field-name>
| <cmr-field-type>java.util.Collection</cmr-field-type>
| </cmr-field>
| </ejb-relationship-role>
|
| </ejb-relation>
