Difference between ABAP and Java Stack or Components

[Former Member]

Hi All,

Where can I find a document that will give good explanation on the difference between ABAP and Java as Netweaver is in place in the market? I need a detailed document differentiating ABAP and Java side by side such as their components and also the benefits or disadvantage for each stack and implementing a dual stack? You can as well give me an overview for this.

I just have to know the basics in Netweaver and also on ABAp and Java.

Many Thanks,

Jennah

Hi Jennah,

Regarding your question about NetWeaver 7.0 SR1 vs SR2:

- NetWeaver SR1 includes up to patch level SPS6

- NetWeaver SR2 includes up to patch level SPS9

Current patch level released by SAP for NetWeaver 7.0 is SPS13.

Hope this helps.

Hi Jennah,

ABAP and Java stacks in NW are so called usage types, which you need in order to implement certain IT scenario. You can find detailed information about those usage types in the service marketplace. There is installation and upgrade documentation and the document is the Master Guide. You may also refer to the technical infrastructure guide which is located at the same place.

There is no differentiation between both stacks, you just need each of them to implement certain IT scenario.

If you have troubles finding the docs in the marketplace let me know and I will give you exact location.

Hi Jenna ,

Iam Here by giving the details of ABAP and JAVA stack and their dependencies further check the link service.sap.com/erp-inst → mySAP ERP2005.

ABAP Stack

AS ABAP is used to provide the ABAP foundation of SAP NetWeaver.

Part of AS ABAP is the Search Engine Service (SES), which enables users to search for

business objects using Search and Classification (TREX). SES accesses Search and

Classification (TREX) functions through the Search and Classification (TREX) ABAP

client. SES replicates the business objects from the ABAP application to Search and

Classification (TREX), so that it can apply Search and Classification (TREX) search

functions to them. When a user enters a search query, the Search and Classification

(TREX) system responds to it, not the database for the ABAP application. For more

information, see the document Installation Guide – SAP NetWeaver TREX Single Hosts /

Multiple Host.

Java stack

AS Java is used to provide the Java foundation of SAP NetWeaver. Among the key

capabilities of AS Java are:

• J2EE Engine – a J2EE 1.3-compliant application server for running enterprise

applications. In addition to the pure J2EE standard technologies, the J2EE

Engine implements complementary technologies, such as Web Dynpro or Web

Services, that are targeted at supporting large-scale, real-business application

development projects.

• SAP Composite Application Framework Core (CAF Core) is a service-oriented

architecture for building and deploying composite applications. It enables

modeling of different service types – entity services that represent a domain

model, application services that implement business logic, and external

services that offer connectivity to back-end services by means of remote

function calls (RFCs) or Web services. Usage type AS Java comprises the CAF

Core runtime environment, while design time tools are part of the SAP

NetWeaver Developer Studio.

• Web Dynpro is the user interface technology for developing professional

business applications for mobile as well as for desktop clients. Web Dynpro

applications can easily be integrated into SAP NetWeaver Enterprise Portal,

providing a unified layout for the end user as well as enhanced navigation

support. Web Dynpro also allows, for example, the development of interactive

forms using the Adobe document services.

• Adobe document services is a set of runtime services that provide a range of

form and document creation and manipulation functions such as:

• Converting XML form templates (created using Adobe LiveCycle Designer)

to PDF and various print formats

• Setting Adobe Reader rights to enable users to fill in and annotate forms,

save and print them locally, and include digital signatures for authentication

using the free Adobe Reader software

Extracting data from SAP applications into Interactive Forms and transferring form data

back into SAP applications using XML

For more information about ALV, see the SAP Library at SAP NetWeaver Library →

Getting Started – Using SAP Software → Working with Tools and Features → Working

with Lists → SAP List Viewer for Web Dynpro .
