USING A TASK FLOW FROM A LIBRARY

USING A TASK FLOW FROM A LIBRARY

With the deptflow task flow library now in place, the last step is to integrate it into the “main menu” page. Start by switching the current workspace back to MainApp, using the list at the top of the Application Navigator. Double-click the Web Content folder’s adfc-config node in the Application Navigator to open it in the editor. Expand the DeptFlow.jar node inside the Libraries file system connection node in the Resource Palette and the ADF Task Flows folder it contains. Drag the deptflow task flow from the Resource Palette, and drop it onto the task flow diagram. Confirm the addition of the Oracle ADF library by clicking Add Library in the alert that appears. Choose View ->

Component Palette, and select the Control

Flow Case tool in the palette. Click the task flow diagram’s Home activity, and then click the deptflow task flow call activity to connect the two activities with a control flow case. Enter the name ManageDepartments on the line. Double-click the Home activity to open the page in the visual editor. Select the Manage Departments commandLink component on the page, and in the Property Inspector, set its Action property value to ManageDepartments to correspond to the new control flow case you created.

When you use the Resource Palette to add a component from an Oracle ADF library, Oracle JDeveloper automatically adjusts your current project’s library list to include the library JAR file and any JAR files that library depends on. To confirm this, double-click the ViewController project and select the Libraries and Classpath page of the Project Properties dialog box.
