Creating View Objects for Queries (continued)

Business components by default are defined in .xml files. However, the Java page of the wizard enables you to optionally create .java files where you can add custom code if desired. If you create the view object without creating the Java files, you can create them at a later time.

Application modules are discussed in a later lesson, but for now you should understand that application modules provide a way to expose business components to applications. To be able to test your view object, it must be contained in an application module. The last step of the Create View Object Wizard enables you to optionally put the view object into an application module. If you choose not to do so now, you may add the view object to an application module later.
