Concept of SAP Web Application Server

SAP systems are used for mapping business processes or business applications. These applications should be implemented independent of the hardware environment used (operating system, database) to the greatest extent possible. For this, the SAP Web Application Server provides two runtime environments: the ABAP runtime environment and (as of SAP Web AS 6.20) also a Java runtime environment.

ABAP (Advanced Business Application Programming) is a programming language developed by SAP. Many business applications of an SAP system are written in ABAP. ABAP has been optimized for developing highly-scalable business applications. Customers can use the ABAP Workbench for developing completely new applications as well as enhancing and modifying SAP standard applications. In doing so, the entire, mighty infrastructure of the SAP Web AS can be used, which also supports the creation of the most complex applications by large groups of developers. The SAP Web Application Server ABAP provides the runtime environment of the programs written in ABAP.

Since SAP Web Application Server 6.20 SAP not only provides an ABAP runtime environment for ABAP but also a runtime environment for Java programs. The integrated Java Web application server is a Java 2 Enterprise Edition (J2EE) application server called SAP Web AS Java.

The Java programming language was first introduced by Sun Microsystems Inc.. in 1995. Java is an object-oriented and platform-independent programming language that has spread across many areas. The Java concept enables the development of a large range of different application types - from classical applications to applets used in websites to client/server applications. Java 2 Platform Enterprise Edition (J2EE) is a manufacturer.s standard for a whole range of software components that are primarily created in the Java programming language. Sun uses the J2EE compatibility test to ensure that the specifications of Java 2 Enterprise Edition are observed.
