Mapping CMP Fields Manually

In most cases, when you create entity beans from tables, you probably want to map fields automatically. However, you can also build up your mappings from scratch (e.g. when the entity beans don't have a corresponding schema object). You may also need to map CMR fields manually after migrating projects to 10.1.2.

To map fields manually:

In the Navigator, right-click orion-ejb-jar.xml and chose Properties. (You can also right click on a CMP entity bean and choose Edit CMP Mappings.) The OC4J EJB Deployment Descriptor dialog opens.
Expand the node for the entity bean you want to map and then expand CMP Field Mappings.
Use the New and Delete buttons to create and remove mappings manually.

If you migrated projects to 10.1.2 that contain CMP entity beans, you need to fix the CMR relationships.

To fix CMR relationships after migrating to 10.1.2:

In the Navigator, right-click orion-ejb-jar.xml and chose Properties. (You can also right click on a CMP entity bean and choose Edit CMP Mappings.) The OC4J EJB Deployment Descriptor dialog opens.
In the navigation tree on the left of the dialog, expand a CMP Entity bean involved in a CMR relationship and click on the CMP Field Mappings child node.
On the panel in the right of the dialog, select the Relationships tab.
Click the Relationship combo box and select each relationship in turn.
When each relationship is visited, it will be automatically updated to the
10.1.2 format.
Repeat steps 2 through 4 for each CMP Entity bean involved in a CMR relationship.
