Whats the difference between ABAP stack, ABAP+Java stack and Java stack

[Former Member]

Hello,

I have a nagging doubt about the difference between the ABAP stack, ABAP+Java stack & the Java only stack. I believe that the method of applying the kernel for all the 3 types is different.

Also can we apply the ABAP support packs through JSPM.

Please put some light on this.

Thank you

and regarding difference between these 3:

ABAP stack only provides the runtme environment for ABAP program

JAVA stack only provides the runtime environment for JRE programs

ABAP+JAVA provides runtime environment for both

Zaheer,

I think subject is self explanatory. But you can find more information on SAP architecture in the attached link.

JSPM can be used for JAVA Stack and updating kernel for JAVA/ABAP+Java stack.

Please check following SAP Note for JSPM.

Yes Zaheer

JSPM is used for applying support packs only for Java stack.

Hello Zaheer

No there is no differnce in the application of kernel to these 3 types

just follow the normal method,also you can apply the kernel using JSPM

But I guess we can't apply the ABAP support packs through JSPM

Hi Zaheer

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

ABAP + Java Stack

Contains both functionalities.

I hope this helps
