Accessor returns can be collections or single objects. Single objects can be displayed only in forms.

Consequently, the master-detail widgets available from the Data Control Palette context menu differ depending on whether the accessor return is a collection or a single object. By default, the table or form provides range navigation for scrolling through the data if the objects are collections.

When a specific data object is selected in the master table, the first related detail data object is displayed in the form below it. The user must use the form navigation to scroll through each subsequent detail data objects.

ADF Master Form, Detail Table Displays the master object in a read-only form and the detail object in a read-only table under the form. By default the table or form provides navigation for scrolling through the data if the objects are collections. When a specific master data object is displayed in the form, the related detail data objects are displayed in a table below it.

This widget is available only when both the master and detail objects are collections. By default, the forms provide range navigation for scrolling through the data if the objects are collections. When a specific master data object is displayed in the top form, the first related detail data object is displayed in the form below it.

The user must use the form navigation to scroll through each subsequent detail data object. By default the tables provide range navigation for scrolling through the data.

When a specific master data object is selected in the top table, the first set of related detail data objects are displayed in the table below it. For a full description of what happens and what is created when you use the Data Control Palette, see Section 5. This sample page displays the service history for each service request. You can change this label as needed.

Each text field in the form contains an EL expression that references a specific attribute binding defined in the page definition file. As you will see in Section 8. Because the object displayed in the form is a collection, by default the form includes four range navigation buttons: First, Previous, Next, and Last. These buttons enable the user to scroll through the data objects in the collection. The actionListener of each button is bound to a data control operation, which performs the navigation.

The execute property used in the actionListener binding, invokes the operation when the button is clicked. If the form displayed a single object, JDeveloper would have omitted the range navigation components.

The table, which displays the detail data collection, is the same as a simple table for more information, see Section 7.

Like the form, the table provides a panelHeader, which defaults to the name of the detail data object. The table tag attributes are bound to the ServiceRequestserviceHistoryCollection table binding object in the page definition file.

As you will see later, in the page definition file, the table binding object references the iterator that retrieves the data from the collection to populate the table. By default, the table includes a tableSelectOne selection facet and a submit button that enables the user to select a specific object in the collection.

The default button is not bound to a method. So to get the selection facet to work, you would need to add an action binding to the button. For example, you could bind the button to a method that enables the user to edit the selected data object, as was done in the SRMain page of the SRDemo application.

For more information about selection facets, see Section 7. The executables element contains a method iterator binding object for the service requests which is the master collection and an accessor iterator binding for the service request history which is the detail collection.

The MasterBinding attribute in the accessor iterator binding references the method iterator for the master collection. This enables the detail iterator to display the correct detail data objects for the current master object for more information, see Section 8. The bindings element contains a methodAction object, which invokes the method iterator for the master collection, and the value bindings for the form and the table.

Note that in the following posts, I will not repeat all this as you can go back to the previous posts to learn more. At the end of the post you will find the source code of the sample application built using Eclipse. Connect to Oracle database using Eclipse: Select the jar file ojdbc6. Create the EJB project: Right-click your project in project explorer and click properties.

Also, check 'Add driver library to build path'. Finally it should look Like the following figure: This is important to select your key generator as Identity, this will cause your entity class to automatically generate primary key. Make these few changes to make the file look like the following: Now we'll create our EJB. Select 'State type' as 'Stateless' and click finish.

Delete the default constructor and make the code look like the following; in the code import all the necessary packages. EJBs has made life easier for us. In the above code, we have created a persistence context, that will take care of our entities, and then we have create our entity manager, that will perform actions on entity classes.
