4.0 Features of SAP Web
Application Server
4.1 Provides highly expandable and robust
Web Infrastructure
The SAP Web Application Server is
the natural choice for customers seeking to combine high
expandability and flexibility with Web development in a diverse
environment. It has a highly efficient caching mechanism for user
access and database access with an optimized lock management and
multiple distributed processes.
4.2 Compatibility with Internet standards
SAP Web Application Server
supports HTTP, HTTPS and other Internet Standards. It also allows a
user, the desired flexibility to be in sync with changing
technologies. It can also act as a server for bringing applications
to the user via a Web browser or for communicating with other
applications in XML or HTML either directly or via a standard Web
server. It can also function as a client to access other Web
applications for collecting information and data.
4.3 Web Application development using
server-side scripting
The server side-scripting concept has been
readily adopted by developers as it provides them with a platform of
choice. It is similar to Active Server Pages (ASP) and Java Server
Pages (JSP) and thus can be instantly adopted by developers. The
presentation of a Web application is organized in Business Server
Pages (BSP). Such an integrated web development environment provides
complete support to a Web developer’s tasks including versioning,
debugging, deployment, and transporting, It also supports scalable
development projects supporting many simultaneous Web developers.
The SAP Web Application Server also supports workflow with the Web
Flow for creating and running comprehensive business logic.
4.4 Open integration capabilties for
Web-based applications in flexible environments
Open integration capabilities
provide both real-time and cached access to SAP and non-SAP
applications, allowing web-based expandibility to customers without
affecting their existing, stable component landscape. All
integration facilities supported by SAP are available with the SAP
Web Application Server. All existing SAP applications, along with
connectivity to standard middleware components or support of
traditional communication standards
is available with the SAP.
4.5 Secure communication
The SAP Web Application Server ensures
authentication and secure communication. It also supports widely
accepted Internet security standards like Secure Sockets Layer (SSL)
and HTTPS. SAP Web Application Server supports digital certificates,
ticketing, and cookies to enable effective user authentication. With
X.509 client certificates, users can be identified without any need
to remember passwords. The SAP WAS also supports the use of cookies
to identify a user.
4.6 Platform independence
The SAP Web Application Server
supports all SAP-compatible operating systems, databases and
middleware. Additionally, it supports open technology standards,
including all major communication protocols and document standards
for all business objects and processes, whether in J2EE or ABAP.
Adaptability to any technical infrastructure from mainframe to small
servers for all major databases is featured. Consumer needs are
readily met by providing user access to mobile devices allowing
deployment on top of any technical infrastructure.
