# Page Data view

The Page Data view provides access to data objects in JSP files.

The Page Data view allows you to add, modify, or delete data objects in JSP files. The types of data objects are listed below.

- Standard scripting variables that are available to all JSP files:
  - `applicationScope` that allows you to add and modify attributes in the application object
  - `param` that allows you to add and modify attributes to be used in the page object
  - `requestScope` that allows you to add and modify attributes in the request object
  - `sessionScope` that allows you to add and modify attributes in the session object

The Page Data view is, by default, shown in the bottom left corner of the workbench. It shares a pane with several other views including the Outline view, the Client Data view, and the Thumbnails view.

You can add, delete, or modify data objects in a JSP file using the Page Data view. To create and modify a data object:

1. In the Page Data view, right click and select New.
2. Select the type of object you want to create. An appropriate wizard opens, depending on the type of object selected.
3. Fill in the fields of the wizard and select OK. The new object appears in the Page Data view. You will need to expand the appropriate section of the Page Data view to see the new object.
4. Highlight the object in the Page Data view. The actions that are available to the data objects include the following:
   - Drag the object directly onto the JSP file. This generates the appropriate controls in the JSP file.
   - Right-click and select Insert New Controls. This has the same effect as dragging the object onto the JSP file.
   - Right-click and select Delete to remove the data object from the Page Data view. This action does not delete existing data object from the JSP file.
   - Right-click and select Configure to modify the attributes of the data object in the Page Data view. This action does not change the existing data objects in the JSP file.
