6.1 Business Server Pages
It is a set of pages that
represent a user interface (layout and page flow definition). The
layout part of a page normally contains ABAP or JavaScript code
which is inserted into the HTML structure. They can contain
server-side scripting code in either JavaScript or ABAP. BSP
applications use all the conventional ABAP technologies, such as
Open SQL and internal tables, allowing developers to create Web
pages quickly. This enables existing SAP logic, data structures, and
interfaces to be directly used in Web applications.
6.2 MIME Objects
In the SAP System, all MIME
objects represent graphics, style sheets or audio and video files
that are managed in a central database called the MIME Repository.
For every new BSP application, an identically named directory in a
repository is created, where you can store all application-specific
MIME objects.
6.3 Theme
It is a container for MIME objects
that are used to adjust the appearance of BSP applications. You can
replace each MIME object in your application with another object
from the file system. Themes are created as individual development
objects in the Web Application Builder and can be assigned to a BSP
application to overwrite preset styles and MIME objects on the pages
of that BSP application.
6.4 Application Class
The business logic of a BSP
application is encapsulated in an application class. This allows
several BSP applications to use the same application class and
provide one business application that contains different interfaces,
such as for various devices, without having to replicate the
business or application logic. The application class is a regular
ABAP Objects class and is realized by means of a global ABAP class,
which implements the access to business data.
6.5 Controllers
It comprises business logic and
application data. Controllers assess the data of an incoming request
based on a model and then select a suitable view for rendering the
response to the user.
6.6 The Navigation Structure
It determines which navigation
request is used to direct the navigation process from a particular
page to the subsequent one.
