The Page Builder assembles the pages that are displayed in the Enterprise Portal. It gets information about the navigation between pages and the layout of the pages from the roles assigned to a user. Information about which roles are assigned to which users is stored in the portal LDAP directory.

If you are using Microsoft Internet Explorer as your Web browser, iView content is sent to the pages in the browser in one of the following two ways:

• Normally the content of an iView is simply displayed as HTML in an iFrame. The browser gets the content individually for each iView from the iViewServer. In other words, the Page Builder assembles a page containing an iFrame for each iView. These iFrames contain URLs pointing to the iViewServer or, in the case of Java iViews, to the Java iView Runtime, or any other source like an Internet Transaction Server (ITS) or any Web site.
• For a small subset of simple iViews, the content of the iViews is assembled in a page on the server. On the client side, the content is put in the iFrame using a script.

The method that is used depends on how the iView is defined.
