Creating Web Dynpro Java iViews 

From a Web Dynpro Java application, you create one of the following:

●      Single iView: The Web Dynpro Java application runs within a single, black-box iView. The portal does not know anything about the internal structure of the application, and the user interface appears as it was designed in Web Dynpro Java.

·        Multiple iViews (one per view): From the Web Dynpro Java application, several iViews are created, one per view. Multiple iViews are useful if you want to enable an administrator to rearrange the layout of the views, to remove a view from the page, or to include non-Web Dynpro content in the page.
