SAP NetWeaver Application server is a component of the NetWeaver solution which works as a web application server to SAP solutions. From the SAP point of view the Web AS is the foundation on which most of their product range runs.

The architecture of SAP Web Application Server can be separated into five areas:

Presentation layer

In the presentation layer, the user interface can be developed with Java Server Pages (JSP), Business Server Pages (BSP), or with Web Dynpro technology. The underlying business layer provides the business content in Java or ABAP.

Business layer

The business layer consists of a J2EE certified run-time environment that processes the requests passed from the ICM and dynamically generates the responses. The business logic can be written either in ABAP or in Java based on the J2EE standard. Developers can implement business logic and persistence with Enterprise JavaBeans (EJB) using the J2EE environment. Developers can also access the business objects of applications running in the ABAP environment to benefit from their business logic and persistence.

Integration layer

The local integration engine is an integral part of SAP Web AS and allows instant connection to SAP XI. The local integration engine provides messaging services that exchange messages between the components that are connected in SAP XI.

Connectivity layer

The Internet Communication Manager (ICM) dispatches user interface requests to the presentation layer and provides a single framework for connectivity using various communication protocols. Currently, modules are available for Hypertext Transfer Protocol (HTTP), HTTPS (extension of HTTP running under the Secure Socket Layer (SSL)), Simple Mail Transfer Protocol (SMTP), Simple Object Access Protocol (SOAP), and Fast Common Gateway Interface (FastCGI).

Persistence layer

The persistence layer supports database independence and scalable transaction handling. Business logic can be developed completely independent of the underlying database and operating system. Database independence is also made possible by support for open standards. The database interface ensures optimized data access from within the ABAP environment through Open SQL. SAP propagates the outstanding capabilities of Open SQL for ABAP to Open SQL for Java and offers a variety of standard Application Programming Interfaces (APIs) to application programmers, such as SQLJ. Other technologies, such as Java Data Objects (JDO) and container managed persistence (CMP) for EJB, or the direct use of the Java Database Connectivity (JDBC) API, are also supported.

Hi,

SAP Web Application Server is the result of continuing development of the SAP Basis system.

In addition to the components of the conventional SAP System, it provides the option of implementing both server-side as well as client-side applications.

SAP Web Application Server supports the HTTP, HTTPS, and SMTP protocols.

You can deploy all your EP application on WAS and test it. WebAS has both Java and ABAP Engine.

The SAP Web Application Server has been renamed to the SAP Netweaver Application Server. You have the two stacks ABAP and Java. All of the Netweaver solutions runs on one of these two stacks. For example Netweaver Portal(formally EP) runs on the java stack.

See this thread too:

There are still two types of server:

The WebAS, part of the Netweaver product. Currenttly it's 6.4 withing NW2004, but eraly next year it's called WebAs 7 within NW2004S.

The R/3 server, now called mySAP ERP (2005).

Since R/3 4.7EE, the base/core for R/3 and WebAs are the same. For 4.7 it's 6.2.

Thanks

Hello!

SAP NetWeaver Application Server

Purpose

The SAP NetWeaver Application Server is the central foundation for the entire SAP software stack. It also provides a platform for other NetWeaver components (Portal, XI, and so on), as well as for ABAP and Java applications. The full J2EE standard is supported. The SAP NetWeaver Application Server is the further development of the SAP Web Application Server.

Integration

There are the following installation options for the SAP NetWeaver AS:

ABAP System (with integrated VM Container). With this installation you can run ABAP programs and selected SAP Java applications.

Java system. With this installation you can run J2EE applications but not any ABAP programs.

ABAP+Java system. For example XI.

Hi,

Web AS means Web Application server,

web application server is a central engine of XI

XI needs to have both ABAP and JAVA WAS

We have the versions of WAS 6.20, 6.40, 7.0....

The application systems >=6.20 can be implement Proxies
