Using JDeveloper to Build Oracle XML Applications, 8 of 11

## Using JDeveloper's XML Data Generator Web Bean

The XML Data Generator Web (Bean) can be used in JSP and Servlet applications. It reads data from a Business Component (View Object) and produces the appropriate XML. The strength of this Web Bean is the following:

- It analyzes the Business Component Application and navigates through it's hierarchy to produce the nested XML.

- It allows specification of an XSL Stylesheet. The Web Bean can then generate HTML, WML, transformed XML, and any other text format.

The Data Generator Web Bean is in the "Data Web Beans" category of the JSP Elements wizard. Figure 14-5 illustrates accessing the XML Data Generator Web (Bean) from the JSP Element Wizard.

Call the Element Wizard from your JSP or XSQL Page by right-cliking anywhere on the Page where you want to include an element. Specify the stylesheet as a parameter in the Element Wizard.

#### Figure 14-5 JSP Element Wizard: XML Data Generator Bean

Once you launch this wizard, you can specify a stylesheet to apply to the XML data that you generate and see the result of your output.

Figure 14-6 is an example output displayed by applying an XSL stylesheet to the employee listing.
