Practices for Lesson 3 Chapter 3 - Page 3 Practices for Lesson 3: Building a Data Model with ADF Business Components Practices Overview This exercise is to familiarize you with the default capabilities of JDeveloper and ADF Business Components. In this practice, you create a business model by using the wizards that are built into JDeveloper. You see how to build a default model without any coding. In subsequent lessons and practices, you learn to build and customize components to meet your specific application requirements. If you successfully completed all sections of the previous practice, you can continue working in the same project. However, if you prefer to start with a clean application that contains everything completed up to the start of this lesson, open Storefront-03.jws and edit the database information as described in step 4 of Practice 2-4.

Practices for Lesson 4 Chapter 4 - Page 3 Practices for Lesson 4: Querying and Persisting Data Practices Overview In the previous set of practices, you used the Create Business Components from Tables Wizard to create multiple types of objects at once. You performed some limited customization of components as enabled by the wizard, such as changing default names and locations. Now you begin to create components that are more customized for your application. First you determine the LOVs that your application requires, and you create read-only view objects to support those LOVs. Next you create entity objects for tables that the application will update, and you also create updatable view objects based on these. You also create and refactor associations and view links. For now, you place all of the view objects and links in the TestAM application module so that you can test them; in the next set of practices, you create custom application modules that are designed for your application. If you successfully completed all sections of the previous practice, you can continue working in the same project. However, if you prefer to start with a clean application that contains everything completed up to the start of this lesson, open Storefront-04.jws and edit the database information as described in step 4 of Practice 2-4. This practice contains some optional steps that are similar to steps already done. If you want to build the entire application yourself, you can complete the optional steps. However, in the interest of time, you may want to skip them. If you do so, you must begin the practices for the next lesson by opening the starter application for that lesson.

Practices for Lesson 4 Chapter 4 - Page 4 Practice 4-1: Creating Read-Only View ObjectsMost of the view objects in your application are required for updating information. However, some view objects exist only to provide data for lists of values. In this practice, you createread-only view objects to support LOVs. Because these read-only view objects are based on SQL queries, you do not require an existing entity object on which to base them. You create them by using either of two wizards: Create View Object Wizard: Creates view objects individually; you must write the query Business Components from Tables Wizard: Creates multiple view objects at once; you select the table for the query that is automatically generated 1.Create a single read-only view object to query the LOOKUP_CODES table by using a bind variable for LOOKUP_TYPE. Name the view object LookupCodeVVO. Create it in the oracle.fod.storefront.view package. Put the view object in your TestAM application module. Use the following query statement for the VO: (You can copy the code from LookupCodes.txt in the \files subdirectory of your \labs directory for this course.)

Practices for Lesson 4 Chapter 4 - Page 9 Practice 4-3: Creating Entity Objects Based on Database Views Although it is easy to create multiple EOs at once with the Create Business Components from Tables Wizard, there are cases where you may want to use the Create Entity Object Wizard to create EOs individually, because that enables a greater degree of customization at the time of creation.This application has some EOs that are based on database views, and it is necessary to designate a primary key for such EOs. You can do that with the Create Entity Object Wizard. In this practice, you create several database viewbased entity objects and designate their primary keys.1.Create an entity object named ProductCategoryEO and base it on the Product_Categories database view. Set the CategoryId to be its primary key. a.To invoke the Entity Object Wizard, you could use the New Gallery. However, there is an even easier way to invoke the wizards: 1)In the Application Navigator, expand the StorefrontModel project.2)Expand the Application Sources and oracle.fod.storefront nodes.3)Right-click the entity node and select New Entity Object. b.On the Name page of the Create Entity Object Wizard: 1)Ensure that oracle.fod.storefront.entity is the package name.2)Enter ProductCategoryEO as the entity object name.3)Ensure that the Database Schema Object option is selected and that the database schema is FOD.4)Click Browse to the right of the Schema Object field. a)In the Select Schema Object dialog box, select the Views object type and deselect Tables.b)Click Query. c)In the list of schema objects, select PRODUCT_CATEGORIES. Note that you cannot multiselect more than one schema object, because you are creating only one entity object with this wizard. d)Click OK.5)If the schema object is not automatically populated in the field, enter PRODUCT_CATEGORIES. Click Next.c.On the Attributes page, click Next to accept all columns.

However, there are some additional associations that you must create for the EOs that are based on database views, and others that you must create where there are no foreign keys. In this practice, you create these additional associations. 1.Create an association that relates CategoryId of the ProductCategoryEO entity object to ParentCategoryId of the same entity object. Name the association ProductCategoriesSubProductCategoriesAssoc.a.Right-click the oracle.fod.storefront.entity package and select New Association. b.On the Name page of the Create Association Wizard: 1)Ensure that the package is oracle.fod.storefront.entity. 2)Enter a name of ProductCategoriesSubProductCategoriesAssoc.3)Click Next. c.On the Entity Objects page of the wizard: 1)Expand ProductCategoryEO in the Select Source Attribute list and select the CategoryId attribute. 2)Expand ProductCategoryEO in the Select Destination Attribute list and select the ParentCategoryId attribute. 3)Click Add, and then click Next. d.On the Association Properties page of the wizard: 1)Leave the check boxes selected in both Source Accessor and Destination Accessor sections.2)Click Next, and then click Finish.

Practices for Lesson 4 Chapter 4 - Page 14 Practice 4-6: Creating Updatable View Objects In this practice, you create updatable view objects based on some of the entity objects you created in previous practices. Because you are creating view objects that are based on existing entity objects, you must use the Create View Object Wizard.In the application that you are building, the user interface displays categories and subcategories. To accomplish this, the model requires two view objects: one that displays the root categories (those without a parent category), and another that displays the subcategories. A view link is also required to set up this master-detail relationship. 1.In the oracle.fod.storefront.uiview package, create two view objects that are based on ProductCategoryEO: RootCategoryVO for those rows whose ParentCategoryId is null, and SubCategoryVO. Place the view objects in your TestAM application module. a.In the Application Navigator, right-click the oracle.fod.storefront.uiview package and select New View Object from the context menu. b.On the Name page of the Create View Object Wizard: 1)Ensure that the package is oracle.fod.storefront.uiview. 2)Enter RootCategoryVO as the view object name. 3)Select the Updatable access through entity objects option.4)Click Next.c.On the Entity Objects page: 1)Expand the oracle.fod.storefront.entity package node.2)Shuttle ProductCategoryEO into the Selected pane.3)Click Next. d.On the Attributes page: 1)Click Add All to shuttle all attributes into the Selected pane. 2)Click Next. e.On the Attribute Settings page, click Next.

Practices for Lesson 5 Chapter 5 - Page 3 Practices for Lesson 5: Exposing Data to Clients Practices Overview In this practice, you take some of the view objects you have created and add them to application modules. You create two application modules in this practice. The first application module displays categories and subcategories. The second application module is for displaying and managing a customers shopping cart.In the interest of time, you create only two of the five application modules that are required for the Storefront application, although you have the knowledge to create all five. When you begin to develop the user interface, you will start with a completed model with all the objects and application modules that you require. If you successfully completed all sections of the previous practice, including the optional steps, you can continue working in the same project. However, if you prefer to start with a clean application that contains everything completed up to the start of this lesson, open Storefront-05.jws and edit the database information as described in step 4 of Practice 2-4.

Practices for Lesson 6 Chapter 6 - Page 3 Practices for Lesson 6: Declaratively Customizing Data Services Practices Overview In this set of practices, you make declarative modifications to your business components. If you successfully completed all sections of the previous practice, you can continue working in the same project. However, if you prefer to start with a clean application that contains everything completed up to the start of this lesson, open Storefront-06.jws and edit the database information as described in step 4 of Practice 2-4. This practice contains some optional steps that are similar to steps already done. If you want to build the entire application yourself, you can complete the optional steps. However, in the interest of time, you may want to skip them. If you do so, you must begin the practices for the next lesson by opening the starter application for that lesson.

Practices for Lesson 6 Chapter 6 - Page 4 Practice 6-1: Defining Control Hints Control hints on entity object attributes enable you to globally define labels, tool tips, and formatting for any views that are based on those entity objects. In this practice, you define and test several control hints. 1.In the OrderEO entity object, format the OrderTotal as currency and set the labels of OrderTotal, OrderDate, and OrderShippedDate to have spaces between the words. You also set some tool tips. a.In the Application Navigator, in the entity package, double-click OrderEO to open it in the editor. b.Click the Attributes tab at the left of the editor. c.Select the OrderTotal attribute and click Edit. (You can also double-click the attribute to open its editor.) d.In the Edit Attribute dialog box, select Control Hints in the list at the left. e.Set the Format Type to Currency. f.Set the Label Text to Order Total by using a resource bundle (for translatable text), as follows: 1)Click the ellipsis to the right of the Label Text field. 2)In the Select Text Resource dialog box: a)In the Display Value field, enter Order Total. This automatically populates the Key field, but you could change the Key value if desired. However, you can leave it at the default for this attribute. b)Enter the following in the Description field: Label for OrderTotal attribute. c)Click the Save and Select button. g.Set the appropriate tool tip text, using a resource bundle. 1)Click the ellipsis to the right of the Tooltip Text field.

Practices for Lesson 6 Chapter 6 - Page 7 Practice 6-2: Declaratively Populating a Primary Key with a Database Sequence Declarative use of a database sequence to populate an EO attribute value relies on existence of a database sequence and a database trigger to use that sequence. For example, the FOD schema has a database sequence named SUPPLIER_SEQ and a database trigger that the DBA created with the following script: CREATE TRIGGER ASSIGN_SUPPLIER_ID BEFORE INSERT ON SUPPLIERS FOR EACH ROW BEGIN IF :NEW.SUPPLIER_ID IS NULL OR :NEW.SUPPLIER_ID < 0 THEN SELECT SUPPLIER_SEQ.NEXTVAL INTO :NEW.SUPPLIER_ID FROM DUAL; END IF; END; This ensures that when a new row is committed with a null primary key, the value from the database sequence populates the primary key. When you use a database trigger to populate the primary key, there are few gaps in the sequence of the primary keys, because the database sequence does not get used until the row is committed.On the Business Components model side, all that is required is to populate the value temporarily, so that the NOT NULL primary key can be committed. That is what happens when you declaratively set the column to use a database sequence, as you do in this practice. 1.Set SupplierEO to use a database sequence at commit time for its primary key. There is already a database trigger defined that populates the primary key from a database sequence if it is null. a.In the Application Navigator, double-click SupplierEO to open it in the editor. b.Click the Attributes tab.c.Select the SupplierId attribute and click Edit.d.In the Edit Attribute dialog box, select Entity Attribute in the list at the left. e.Select DBSequence from the Type drop-down list.

Practices for Lesson 6 Chapter 6 - Page 9 Practice 6-3: Designating History Columns There are several mandatory attributes in many of the entity objects that record information about the record: who created it and when it was created, who last updated it and when it was last updated, and a version number. These attributes can be automatically populated if you designate them as history columns. In this practice, you modify three of the entity objects so that the history columns are populated automatically.1.In the SupplierEO entity object, designate the following columns as history columns and ensure that they are automatically populated at run time: CreatedBy, CreationDate, LastUpdatedBy, LastUpdateDate, and ObjectVersionId.a.In the Application Navigator, double-click SupplierEO to open it in the editor, or click its tab if it is already open.b.Click the Attributes tab.c.Select the CreationDate attribute and click Edit.
