Difference java stack and abap stack

hello experts,
Difference between java stack and abap stack

Hi
ABAP Stack
The application data in the SAP system is accessed in
the ABAP stack via platform-independent ABAP programs.
ABAP stack is used to run ERP applications mainly MM,SD,FICO etc
Currently in most of the installation you can found mixed stack(ABAP+JAVA)
JAVA Stack
The Java side of the SAP Web AS is often referred to as SAPWeb AS Java or
as the Java stack.
This central SAP Web AS Java instance consists of two separate
instances plus one special application, the Software Deployment Manager (SDM).
These two separate instances that build the central SAP Web AS Java instance are
a standard SAP Web As Java instance, offering a Java dispatcher process and one
or more Java server processes and the so-called SAP Central Services instance
(SCS). The SCS instance offers two processes, exclusively used by the Java side
of the SAP Web AS: the enqueue services and the message service. These two
services only work for the Java side of the SAP system.
Java Stack is mainly used for SAP Portals and you can host Internet/Web based application written in JSP/EJB ,Java Stack uses Java Threads to run application,
Also, Xi requires Double stack
ABAP + JAVA Stacks
Bcoz some components are developed on JAVA
Some components are developed on ABAP Based.
JAVA:
Integration Builder
SLD
Adapter Engine
Runtime Workbench
ABAP:
BPE
Integration Engine
Integration Engine and the Integration server reside on the ABAP Stack. All the Execution of the IS part will be done on ABAP Stack. we can monitor the processed XML messages also in SXMB_MONI( ABAP Stack)
Adapter Engine will reside on the JAVA Stack. All the IR, ID, SLD, RWB Application are developed on JAVA Stack, so thats why we need JAVA Webstart to run these Applications
All the Adapter related Errors we can see in RWB, Communication channel monitoring( Developed and sits on JAVA stack)
Hope this clears your doubts
Thanks

JAVA API AND ABAP API SIMPLE SCENARIO

Hello MDM gurus
I have never used any Java API or ABAP API to leverage and present MDM functionalities on front end systems like portal,etc...
Could you please give me all the required to play around with JAVA api and ABAP api's.
Points will be given to every valuable answer.
Thanks

Hi Nazeer,
In order to use Portal you need Java APIs and to start with refer the MDM Java docs to get the basic idea of various classes and methods to be used in developing the simple java application and access it using portal.

Sample code for Duplicating Repository
public class TestDuplicateRepository
           public static ConnectionPool simpleConnection;
           public static RepositoryIdentifier repIdentifier,repIdentifier1;
     public static String session;
     public static String connection = "MDMServer_Test";
     public static String repository1 = "Test_Repository";
     public static String repository2 = "Test_Duplicate";

     public static void main(String[] args)throws CommandException, ConnectionException
               //Creating Connection.
               simpleConnection = ConnectionPoolFactory.getInstance(connection);
               //Establishing connection with Repository.
               repIdentifier = new RepositoryIdentifier(repository1, connection, dbmsType);
               repIdentifier1 = new RepositoryIdentifier(repository2, connection, dbmsType);
               //Creation Sever Session.
               CreateServerSessionCommand createServerSessionCmd = new CreateServerSessionCommand(simpleConnection);
               createServerSessionCmd.execute();
               session = createServerSessionCmd.getSession();
               //Authenticating Server Session.
               AuthenticateServerSessionCommand auth= new AuthenticateServerSessionCommand(simpleConnection);
               auth.setSession(session);
               auth.setUserName("Admin");
               auth.setUserPassword("Admin");
               auth.execute();
               session = auth.getSession();
               //Duplicate Repository Command
               DuplicateRepositoryCommand duplRepCmd = new DuplicateRepositoryCommand(simpleConnection);
               duplRepCmd.setDBMSUserName("sa");
               duplRepCmd.setDBMSUserPassword("abc");
               duplRepCmd.setSession(session);
               duplRepCmd.setSourceRepositoryIdentifier(repIdentifier);
               duplRepCmd.setTargetRepositoryIdentifier(repIdentifier1);
               duplRepCmd.execute();
Similarly you can try with Getting server version, Archive repository and then move on to adding,modifying records etc.

How could JAVA API and ABAP API useful to MDM.

Hi Experts,
How could JAVA API and ABAP API useful to MDM, and any coding in Java or ABAP is required in MDM.

Hi Reema,
Java API and ABAP API are verry usefull to MDM to integrate MDM with other SAP componants like SAP R\3, EP etc. :
It dose not required any coding in MDM infact in JAVA API coding can be done on NWDS(Netweaver Developer Studio).And for ABAP API coding is done on SAP R\3 System in ABAP editor.
JAVA API:
By using Java API MDM client operations can be performed.For one need to install NWDS and to deploy some .jar files and with the help of standard classes and interfaces it can be connected to MDM server and various operations like create repository ,connect to repository ,Data mainuplation etc.
ABAP API:
Suppose you have an Expert abaper and you want him to perform MDM operations.In that case he need not to learn MDM basic Data types infact by doing some settings on R\3 and MDM server side an ABAPer can perform
MDM Cnsole and MDM Data Manager level operations.
you can go through these links

/people/bv.pillai/blog/2006/11/28/installing-mdmtech-add-on-and-configuring-the-mdm4a-mdm-for-abap-api
Here the coding is done on SAP R\3 system.
hope it will give you some idea about Java API and ABAP API

Regarding Java mapping and ABAP Mapping

Hello,
If I suppose to do Java mapping or ABAP mapping, Is there any pre requisite to perform these two mappings?
If exist what they are?
How to perform them?
Thank you

Hello jyotsna,
Java mapping can be used when you have complex mapping structures.
We can do most of the times for our requirements through Graphical mapping.
When the structures are very complex to build you can go for SAX (Simple API for XML) or DOM (Document Object Model) parsers.
Message mapping internally generates DOM parser.

ABAP mappings run on ABAP Stack and are developed in the ABAP workbench of the Integration Server.
You normally do not need to use the ABAP mappings and is preferable for someone with ABAP programming background. I should say JAVA functions would suffice any complex scenarios.

You need to provide the name of your mapping program maually , you see it is an input box.
just provide the name of abap mapping program it will work.
and one more thing you cannot test abap mapping program in integration builer you need to test in abap only.
use tcode: SXI_MAPPING_TEST for testing abap mapping

Java Proxy and ABAP Proxy

hi,
can any one send me some documents on Java Proxy and ABBAP Proxy
regards,
John

hi,
Proxies are nothing but a mechanism to shift the application logic from the XI server onto the sender or reciever system so as to reduce the effort on the side of XI.Depending upon where the proxies are generated ,it is differentiated as client proxy ( sender ) and server proxy ( receiver ) .In R3 system having WAS 6.2 and above its already has an inbuilt small IE so the proxy generation is favoured and possilbe,for more on this please go thru the following links
Proxies: are interfaces which will get executed in the application system. They can be created only in the system from message interfaces using the proxy generation functions.
The biggest advantage of the proxy is that it always by passes the Adapter Engine and will directly interact with the application system and Integration engine - so it will and should give us a better performance.
The literal definition of a proxy is an object / process authorized to act for another; an agent or a substitute. In simpler terms, proxies in the XI context are objects used to encapsulate the creation (from a sender system) or parsing of XML (at a receiver system) as well as the communication with the relevant runtime components required to send or receive those messages. The Proxy Runtime controls these objects / processes, and can itself be controlled by the applications it communicates with.
The Proxy currently has the following components available:
1. ABAP Proxy Communication using XI or Web Services
2. Java Proxy Communication using XI (J2EE)

Report Result differs between Java Web and ABAP Web

Hi Experts,
We have a BW Report in BI NW 7.0. When we run the report in Bex (ABAP Stack) or ABAP Web the default results are different from the Java Web Results. There are no selection differences.
Please help me if I miss any settings or any corrections required.
Thanks in advance.
Deepthi.

Hi,
The function Calculate Results as ... could not be applied everywhere.
Recalculation of a resutls row is always based on the amount of detail cells subordinate to this cell, which is the finest details of a drilldown. It is not possible to recalculate resutls in hierarchical lists. This means that calculation of a results cell is not performed if a row or column with an expand symbol is subordinate to it. With recalculation, the newly calculated result has to change with each expansion of a node subordinate to it. This is not supported for technical reasons and would only confuse the user.
Note, however, that Calculate Results as -> Suppress Results is always executed, because the problem above does not apply in that case.
Notification Number BRAIN 141
Please refer the notes
Note 1071067 - "Calculate Singlve Value as" in list without drilldown
Note 997421 - Calculate as 'Supress Result' on hierarchy nodes
Note 857895 - 'Suppress results' for the display hierarchy
Note 853058 - Calculate Results/Single Values as ... priority rules
Hope this helps.

Java Trial AND ABAP Trial

I succesfully installed the Netweaver 2004s ABAP Trial.
Now I want to also dig deeper into SAP Java, especially Web Dynpro Development.
What am I supposed to do? Can I download and install the Java Trial in parallel with the ABAP Trial? Can I run them both at the same time for example to access ABAP function modules from Java via RFC?
And what's that SAP NetWeaver Application Server, Java EE 5 Edition for? The Java Trial already comes with an app server...
Sorry for being stupid, I'm a SAP ABAP business programmer for many years now and am confused with all that system administrative wording...

Hi all
I have no success install ABAP and JAVA testdrive on same server. What versions have you installed?
I have installed the abap testdrive 04s SP11. All seems to be ok.
Now i try to install SAP NetWeaver 2004s Java Trial Version SP9 on same server, but I get some warnings and errors:

Different behaviour of F4 searchhelp BADI in Java Web and ABAP Web

I implemented the Badi RSR_VARIABLE_F4_RESTRICT_BADI to restrict the values in the F4 search help of variables in a query.
When executing the query in ABAP Web or in the BEx Analyzer in Excel everything works fine.
The variable popup shows up and when I hit F4 on a characteristic it jumps in the code once and determines the values I want to see
BUT: When I execute the same query in Java Web runtime, the Badi is executed 6 (SIX) times before even displaying the variable screen Anyone has got an idea?
As I am determining the results in the search help depending on transactional data in a cube it's a big mess when executing this piece of code 6 times even if I do not need it at that stage.....
As a small workaround i created a constructor for the implemented class, as this is only called once at runtime, but this cannot be the solution.

Hi Stefan,
Have a read of this article:
http://sapdiary.com/index.php?option=com_content&view=article&id=12787:restricting-the-value-help-in-the-variables-screen-of-a-query&catid=81:data-services&Itemid=81
Also double check you are honouring the spirit of all the input parameters.
The symptom you describe occurred in the older solution using a customer exit (function module) when the "Variable Name" parameter was used incorrectly in the code, hence it did not behave as the API expected.
When you have it in debug mode and are looking at all the available variables in memory (global and local) do any of them change between the six calls?
Hope this helps,
John.

Hi Friends ....Difference between SAP memory and ABAP memory

Hi Friends,
I faced a interview and they ask this question
What is the difference between SAP Memory and ABAP memory..

conti
SAP Memory
SAP memory is a memory area to which all main sessions within a SAPgui have access. You can use SAP memory either to pass data from one program to another within a session, or to pass data from one session to another. Application programs that use SAP memory must do so using SPA/GPA parameters (also known as SET/GET parameters). These parameters can be set either for a particular user or for a particular program using the SET PARAMETER statement.
Other ABAP programs can then retrieve the set parameters using the GET PARAMETER statement. The most frequent use of SPA/GPA parameters is to fill input fields on screens.
ABAP Memory
ABAP memory is a memory area that all ABAP programs within the same internal session can access using the EXPORT and IMPORT statements. Data within this area remains intact during a whole sequence of program calls. To pass data to a program which you are calling, the data needs to be placed in ABAP memory before the call is made. The internal session of the called program then replaces that of the calling program. The program called can then read from the ABAP memory. If control is then returned to the program which made the initial call, the same process operates in reverse.
A simple example of ABAP memory is using the EXPORT/IMPORT statements.
Here in this program, I get the data, export it to memory,
clear out the internal table in my progam, then reimport the data into it and write out the data.
You probably wounldn't do this in a normal program,
but this is how you can pass data from program a to program b when A Submits program B.
report zxy_0002 .
data: it001 type table of t001 with header line.
select * into table it001 from t001.
export it001 = it001 to memory id 'ZXY_TEST'.
clear it001. refresh it001.
import it001 = it001 from memory id 'ZXY_TEST'.
loop at it001.
write:/ it001-bukrs, it001-butxt.
endloop.
SAP Memory
SAP memory is a memory area to which all main sessions within a SAPgui have access.
You can use SAP memory either to pass data from one program to another within a session,
or to pass data from one session to another.
Application programs that use SAP memory must do so using SPA/GPA parameters (also known as SET/GET parameters).
These parameters can be set either for a particular user
or for a particular program using the SET PARAMETER statement.
Other ABAP programs can then retrieve the set parameters using the GET PARAMETER statement.
The most frequent use of SPA/GPA parameters is to fill input fields on screens
ABAP/4 Memory
ABAP memory is a memory area that all ABAP programs within the same internal session can access
using the EXPORT and IMPORT statements.
Data within this area remains intact during a whole sequence of program calls. To pass data
to a program which you are calling,
the data needs to be placed in ABAP memory before the call is made.
The internal session of the called program then replaces that of the calling program.
The program called can then read from the ABAP memory.
If control is then returned to the program which made the initial call, the same process operates in reverse.
SAP memory
The SAP memory, otherwise known as the global memory,
is available to a user during the entire duration of a terminal session.
Its contents are retained across transaction boundaries as well as external and internal sessions.
The SET PARAMETER and GET PARAMETER statements allow you to write to, or read from, the SAP memory.
ABAP/4 memory
The contents of the ABAP/4 memory are retained only during the lifetime of an external session
(see also Organization of Modularization Units).
You can retain or pass data across internal sessions.
The EXPORT TO MEMORY and IMPORT FROM MEMORY statements allow you to write data to, or read data from, the ABAP memory.

Compatability of J2EE and ABAP Editions

Are these two sneak preview editions (Java Edition and ABAP Edition) compatable such that they both can be installed on the same XP system?
Presumably the Full edition which is not yet released will provide for a proper J2EE add-in installation.
But in the meantime, should it be OK to install the J2EE ABAP installations separately on the same system?
If yes, if there any special approach to the instance numbering that must be followed?
Thanks!

Thanks for those hints. I have installed the ABAP version (SID = NSP). After that the J2EE installation (J2E) is smart enough to figure out that instance 00 is already taken and uses 02 (without any input from the installer).
But ... unfortunately ... Load Java Database Content step just hangs. The last message in the log is an INFO message (see below). It seems like a lot of people have reported problems like this one.
So close!

The most frequent use of SPA/GPA parameters is to fill input fields on screens
ABAP/4 Memory
ABAP memory is a memory area that all ABAP programs within the same internal session can access
using the EXPORT and IMPORT statements.
Data within this area remains intact during a whole sequence of program calls. To pass data
to a program which you are calling,
the data needs to be placed in ABAP memory before the call is made.
The internal session of the called program then replaces that of the calling program.
The program called can then read from the ABAP memory.
If control is then returned to the program which made the initial call, the same process operates in reverse.
SAP memory
The SAP memory, otherwise known as the global memory,
is available to a user during the entire duration of a terminal session.
Its contents are retained across transaction boundaries as well as external and internal sessions.
The SET PARAMETER and GET PARAMETER statements allow you to write to, or read from, the SAP memory.
ABAP/4 memory
The contents of the ABAP/4 memory are retained only during the lifetime of an external session
(see also Organization of Modularization Units).
You can retain or pass data across internal sessions.
The EXPORT TO MEMORY and IMPORT FROM MEMORY statements allow you to write data to, or read data from, the ABAP memory.

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

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

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

Testing SSL Connections, differences between ABAP and JAVA stacks

Hello,
   I am trying to test an outbound SSL connection to a partner.   I already have multiple outbound connections to many partners, but this new one is causing an issue.   Our firewalls between the two sites are opened as required, I verified that I can telnet to the 443 port of their sever.   I then attempted to connect to their URL, via a Java SOAP message, and it is rejected. Some kind of error regarding our handshake.
   In an attempt to troubleshoot the issue I entered their URL in SM59 as a HTTPS connection, tested it, it worked fine.   Which indicates to me that the ABAP side works fine.
   I do the same on the Java stack, via the SOA Manager: Destinations, and it fails.
"Error during ping operation: Error while silently connecting org.w3c.www.protocol.http.Http.Eception: Peer sent alert: Alert Fatal: unexpected message"
I was thinking that maybe the remote partner only allows specific types of SSL version connection, and the Java side is too low. i.e. the partner only allows TLS v1, and we are attempting to use SSL v2.    Is there a place to set this on the Java side? I know I can set inbound parameters on ICM via SMICM.
Any help or assistance would be most appreciated.
Thanks,
Michael Montone

Hi,
I suggest that you verify if you use the same release of the SAP Cryptolib for the ABAP and the Java stack.
This could explain a difference of support for SSL or TLS.

Hi ,
Integration related will be done in Integration Engine ,, it means in ABAP Stack..
I mean ..
Integration Engine and Business process Engine on ABAP Stack..
Rest of all components are on JAVA Stack..
see the below links
