Queries regarding WAS (Web Application Server)

[Former Member]

Can any one tell about WAS, what is WAS and what are the uses in Integration?

What is use of abap and java engine in webas? If WAS has Integration Engine, can it have Integration Server to integrate two systems which can generate XML? From which SAP version it is available, will it come along with new version or shd it separately install? If I upgrade to new version greater than 4.7c will it automatically come with WAS?

Hi,

Please find here with you some answers to your questions,

Can any one tell about WAS, what is WAS and what are the uses in Integration?

With the SAP Web Application Server you can implement both server-based and client-based Web applications. Server applications (for example, online shops or portals) can be created in the integrated development environment or in an external tool. These applications can contain Web pages as well as static HTML code and dynamic script code.

The SAP Web Application Server can execute – depending on your chosen installation option – ABAP and/or Java programs. This means you can use the ABAP-based Business Server Pages and a Java technology (JSP, etc.) to create Web applications.

--> SAP® Web Application Server is a scalable and reliable component platform that supports the development and operation of Web applications and Web services based on Java 2 Platform,Enterprise Edition (J2EE), and ABAP™. SAP Web Application Server embraces native Web technologies while providing all the benefits of what has previously been referred to as SAP® Basis – including the benefits of the proven and scalable data, system, and software management capabilities that SAP is known for.

SAP Web Application Server provides open interfaces to the market-leading Java integrated development environment (IDE) for the development of presentation and business logic.

What is use of abap and java engine in webas?

--> SAP has offered a additional programming environment with ABAP that is Java. Java is a standard in the industry whereas ABAP is only for the SAP system. Java and ABAP have much in common. We can develop application in any environment but then its good if we can integrate the industry standard(JAVA) to the proprietary standard(ABAP). Now as we all know JAVA applications really provide a good development framework so SAP thought of integrating JAVA with ABAP as well. So for ABAP environment they have ABAP engine and for JAVA they have JAVA engine.

Data is not directly shared with these two engines, we require RFC's and BAPI's for exchanging the information between these two engines. ABAP still have some advantages as a backend technology and Java is more advantageous for User interfaces and Web Services. So its better to use these two integrating the positive points of both Technology.

We can even write a JCo (Java Connector)program to access the ABAP system from Java. All this is done so that both these technology can work together for more reliable output.

Since we are working at present on WAS700 I can give few words here.

SAP is added its own SAPJVM to NY WAS(700). Change in user interface for portal and WebDynPro.

Added new control, change in underlying functionalities

From which SAP version it is available, will it come along with new version or shd it separately install? If I upgrade to new version greater than 4.7c will it automatically come with WAS?
