Java for Net weaver

Hi,
For a ABAP person what would be the easy method who doesn't know JAVA and want to learn JAVA and SAP Netwaver.
How to start with .
Thanx & Regards,
Naidu.

Hi,
Easy way is not always the best way.
Before you program Netwaever you should know how to program J2EE.
Before you program J2EE you should know how to program Java.
So up the stack:
http://java.sun.com/docs/books/tutorial/
for Java knowledge.
http://java.sun.com/j2ee/tutorial/1_3-fcs/
for the J2EE knowledge.
Then docs here at SDN, SAP Notes, the JCO tutorial , papers etc.

Could EPM add in for Microsoft 7.5 and EPM add in for Net Weaver 10.0 work together

Good day,
We are going to start a new project, where the client already has EPM add in for Microsoft 7.5. We need to migrate this system to EPM add in for Net Weaver 10.0. When we would testing systems we need to have on the one local PC 2 products :EPM add in for Microsoft 7.5 and EPM add in for Net Weaver 10.0 to compare results. Is it possible to use them parallel? Is there any SAP documents or official materials where is information about this situation.
Many Thanks for the answear!

Hi Natalia,
I have the same problem to migrate project, you can' t have both of them logged on at the same time
I solve my problem with a virtual machine, i use VMWare with BPC 7.5 version and host machine with BPC 10 Version.
I hope this will help you.

Does Session Sharing feature provided by SAP Net Weaver application server

Hi All,
Session Sharing is an additional feature provided by Tomcat , Weblogic and Web sphere application servers.
Is this feature available in SAP Net Weaver application server?
Brief description on Session Sharing
Session Sharing specifies whether HTTP sessions are shared across multiple Web applications.
In Weblogic this is an optional feature customizable in weblolgic-application.xml
Sample weblogic-application.xml
<?xml version='1.0' encoding='UTF-8'?>
<weblogic-application xmlns="http://www.bea.com/ns/weblogic/90" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<session-descriptor>
<persistent-store-type>replicated_if_clustered</persistent-store-type>
<sharing-enabled>true</sharing-enabled>
</session-descriptor>
</weblogic-application>
session-descriptor (Optional Element ) - Specifies a list of configuration parameters for servlet sessions.
sharing-enabled (Optional Element ) - Specifies whether HTTP sessions are shared across multiple Web applications. Default value is false.
Thanks in advance.

Hi,
You cannot set up Garbage collection frequency. it is internally handled by Java when the Heap size is filled up.
You can always fine tune your server to SAP recommendations.
Note 723909 is a good starting point.
Also other checks include that you use SAP recommended Java versions, OS patches and also that you have enough physical memory.
Thanks & Regards,

SAP Net weaver Development studio

Hi All,
We are going to implement SAP Portal in my office soon .
I am planning to try small Java applications etc . pls advice is it posible to download and use SAP Net weaver Development studio
without sap in my system .
Just i wanted learn basics of SAP Net weaver Development studio.
Thanks,
Rani

Hi Rani,
answering your question in short: yes and no.
A bit longer: yes, if you have authorization to the NWDS download page, then you can download it, and work with it locally, but without a SAP J2EE Engine you cannot test your application in runtime, as you cannot deploy it anywhere.
As an alternative, you can also create a Developer Workplace installation, which includes an NWDS and a local J2EE Engine you can use to do local tests. Both will be installed on your client side machine. This kind of engine intallation is not meant to be serve a complete server, but meant to be only for testing your local developments on client side.
Some info on DWP:
#924983 -- Developer Workplace Installation for SAP NetWeaver 7.0
(http://service.sap.com/sap/support/notes/924983)
A forum thread in this topic:
Netweaver developer workplace and Infrastructure
(I tried to find a CE version of these infos, maybe someone else can add this info.)

Why SAP has taken Java for their development instead of ABAP completely

Hi
I am Neelima, new to SAP and abap,
Can u please explain
Why SAP has taken Java for their development instead of ABAP completely
Thanks in advance
Regards,
Neelima

Hi Neelima ,
Answer to Q . Why SAP has taken Java for their development instead of ABAP completely ?
First of all in my view SAP has not taken Java as Such instead of ABAP .
But you nowdays whole lot of java is coming in SAP by doors of SAP NetWeaver .
Now why they choosed java only IN MY VIEW
1) Java is open source so SAP in tie up with SUN can develop SAP specific APIs and thats what happenings . In Net Weaver Developer studio (NDS of SAP like eclipe of Java ) we use packages ,classes , methods for SAP.
2) In my view Java is rocking in Web world , Every single popular product ( like IBM MQ series , Oracle Apps ) is making use Java for making things web based .
So why not SAP .
3) Now data ultimately data is getting saved in XML . And java is best to deal with that . In SAP also Idoc data is stored in XML and so same data can be used anywhere inspite of Platform , technology .
4) Java has much established base of web Solution , Web services .They have got beautiful architecture so that Best Web sevices can be developed with EJB (Enter prise java beans ) , sturts and all .
5) Now Its time for SAP to be Mobile Enabled .i.e. to Run SAP over PDA , Blackberry .Such solutions possible with SAP + Java combination .Java provides that framework to understand Mobile OS platform.
6) Another thing now Its time of EAI (Enterprise Application Integration) . Integration is future . Multiple product integrated and used togetherly , exchanges data. Take case SAPs message goes to Sieble , people soft .For this Java + XML is best suied as both product understand it .
Utimately SAP is Using java to provide Best Web ERP solutions
But it does not mean ABAP is not there. With webDynpro ABAP you can do every thing that WD java does . In fact incase if you have existing ABAP recourses then use WD ABAP for developing web services in SAP. In uses OO ABAP as base programming language .
Please refer to this link
IS Webdynpro for ABAP/JAVA is same?
so hope your question is cleared
Cheers

Net-Weaver 4.0 installed on Windows-7 . and RRMX is not working...

Dear Experts,
We are using Net-Weaver 4.0 , BW 3.5 and Office-2007. But recently we have installed these over WINDOWS 7.
Previously it was working fine with WINDOWS - XP.
And now after installation , when I put RRMX transaction. I am getting error.
Please suggest , What shall I do ?
Thaks,
Utpal

Hi Utpal:
Probably you need to install a Front End Patch (FEP), with an "S" account you can download it from the SAP Marketplace.
What is the error message you get? search for related SAP Notes with details on this issue resolution. For example SAP Note 1533608 recommends installing FEP 400 of BW 3.5 Add-on of GUI 720 to solve issues with RRMX Transaction Code.
To download the file do the following.
1. Open the link https://websmp102.sap-ag.de/support
2. Click on the Tab "Software Downloads"
3. Click on the Section "Support Packages and Patches"
4. From the Menu on the left Click on "Browse our Download Catalog" option.
5. Click on the link "SAP Frontend Components"
6. Click on "BI ADDON FOR SAP GUI"
7. Click on "BW 3.5 ADDON FOR SAP GUI 7.20"
8. Click on "Win32" to display the list of available FEP for download.
Regards,
Francisco Milán.

Is SAP net weaver environment necessary to configure/customize IC Webclient

Hello Expert,
Is SAP net weaver environment necessary to configure/customize IC Web client and Internet sales?
Please guide me.
Thanks & Regards
Satish

Single Sign On is optional.
What would happen is that the user that's using the Web Application Designer will have to have access to Portals, and the portal Sign On screen will appear once that user executes a Web Template.
It also depends on the Portal Strategy and the Security Strategy of your client. For example, the portal may only grant access to those used IDs in the Active Directory, so if your BEx WAD user is not defined in Active Directory that user will not have access to portals, and will not be able to execute the Web Template.
Cheers.

SAP Net Weaver Version 7.0 Installation

Hello Experts,
Iu2019m totally new in SAP products and I would like to ask about the installation steps as the following:
1-Iu2019m planning to install the following SAP products in one server (16GB RAM, 1TB HDD, Win 2003):
A-Oracle Database Version 10.2
B-SAP Solution Manager Version 7.1
C-SAP Net Weaver Version 7.0
D-SAP ERP-EHP5
E-SAP Base Line
F-SAP CRM
G-SAP SRM
So, is that the right order for the installation, can I install all this products in one server as a demo server?
2-I start the installation steps and I have finished the Database setup (10.2 then patch 10.2.0.4) then installed SAP Solution Manager Version 7.1 and I select Central System Installation Type, and the installation is Finished Successfully, but after the installation I did not find any new programs under windows start menu or all programs, I just found SAP Management Console, so is that the right behavior for this type of installation or I miss something?
3-I follow up all the steps that found in Solution Manager Master Guide until post installation tasks, the first step is to logon the application server, but I did not found it in the all programs menu is that the right behavior?
Thank You And,
Best Regards.
