Hello,
I want to separate my instance dual stak ABAP+JAVA, I don't lnow what's the better procedure
or move ABAP or move JAVA, both stay in one server:sapnwd01 (it have BI,EP components)
We wear Solaris 5.10, Oracle 10.2.0.4, SAP NetWeaver 7.0 (ABAP+JAVA)
ABAP have SID:NWD with the same database NWD, and number:04
JAVA have SID:NWD with the same database NWD, and number:14
And these are my profiles:
sapnwd01:nwdadm 8% pwd
/sapmnt/NWD/profile
sapnwd01:nwdadm 9% ls -l

Hi Sunny,
Thanks for you comments.
What's about the conecctions between JAVA-->ABAP and with development are these assigned to my SID:NWD?
Can I install another JAVA instance and after remove JAVA from instance ABAP+JAVA?
Development team only give me one or two days for it they don't want loose time in develop.
Do you have any links to these document?

Move Web Analyzer component to another server

Hi All,
I have to switch the Web Analyser component to another server in the same FARM.
Is there any steps available to move the service without any data loss?
Web Analyser component can be created by updating the deployment.xml file in Admin server. But how we can webanalyser files available in %FASTSEARCH%/data folder?
Thanks

Hi,
The way to move mailboxes from one database to another database is available. When you move a mailbox, you're moving it from a source mailbox database to a target mailbox database. The target mailbox database can be on the same server, on a different server,
in a different domain, in a different Active Directory site, or in another forest.
You can refer to the following articles:

Move Central Instance to Another Server

Hello expert,
Now we have a distributed system: CI on server 1, DB on server 2. Now we want to move the CI to another server 3 without change the DB server.
We get some information from link Move the central instance to another server in SAP
We have few questions:
1. Can we change the SID of CI with method provided in link?
2. Any other additional steps should we do?
Thanks & Best Regards,
Tong Ning

Hi Tong,
You can install a new SAP instance (CI) on the new server as your DB is not moving and is on different host, and replicate important files from your old CI host.
For eg, the host file, services file, trans directory and some work directory contents.
Also, if your server on same OS or different ?
You should check the compatibility of new OS and DB in service market place (PAM).
For changing SID, please use standard guides and tested WIKI links.

BI Java and BI ABAP -RSPLAN issue

Hi All
We are working with BI system ,using BI 7.0 Java and BI ABAP as separate systems on same host.
Already run the template intaller for BI Java and ABAP integration.
But facing some issue ,when going ot BI ABAP and RSPLAN and clicking the Start Mideller
it is opening a browser as http://host:8000/sap/public/myssocntl?sap-client-XXX
Since this is not correct and it should open BI Java portal instead of ABAP stack page.
Instead this should open a Url like this http://host:5XX00/webdynpro/dispatcher/sap.com/biplanworkbench1/Modeler?
I check on BI ABAP system under SAP Reference IMG -> SAP Customizing Implementation Guide-> SAP NetWeaver _> Business Intelligence-> BI Integrated Planning -> Settings for Starting the Planning Modeler.
There the default Url is BEx Portal Server and the url is
http://host:5XX00/webdynpro/dispatcher/sap.com/biplanworkbench1/Modeler
Can anybody let me know why this is going to ABAP server instead it should go to Java.
Regards

This depends on the version of your Netweaver Java AS. If you are running 7.0, you will have to use the Jco framework. The Jco framework is deprecated since 7.1 though. If you want to build a RFC server in 7.1 or higher, it is adviced that you set it up through JRA.
Implement an RFC server in 7.0:

How to restart Java Engine in ABAP+JAVA dual stack installation ?

Dear Experts
if i use stopsap r3 in this dual stack installation - it stops both ABAP & JAVA Web Application Servers.
I want to restart only JAVA Weba pplication server.
How do it ?
Thaks in Advance !
Rgds

But theoritically they are 2 indpeendent installations like
AS ABAP
AS JAVA
..Do you aggree ?? really am not good on basics!!
During the installation also - if select AS ABAP & AS JAVA - it will become dual installation
and it does not show
any dependency while installing that AS JAVA requires AS ABAP.[Installation Component Selection and Dependency Screen shot|http://i303.photobucket.com/albums/nn153/S0002919350/SAP%20Issues/Oracle_Patches.jpg]
Installation Component Selection and Dependency Screen shot
Is it because if AS ABAP is down - AS JAVA UME is 001 client - and Java authentication fails ?
Can we de attatch from ABAP UME for my requirement like - running JAVA WAS alone w/o ABAP.

Mapping of Java object to ABAP

Hey Guys,
i am facing the following problem. in abap i get a table from a function back. i am copying these values to my outboundcontainer. in java i map them to an array of beans, work with them...
now i want to store them in my database in the backend system. how do i get there values back into abap.
do i have to create a "toString()" function in java and pass a string to abap or do i add each single javavariable into my outbound container?
thank you very much
Philipp

Hi Phillipp,
You can do this by following the reverse steps that you have done to get the values from ABAP to Java.
At the JAVA end :-
1. You can use the "toString" function to get the values from the beans to string format.
2. Append these values into the outbound container giving them "fieldnames" similar to what you did to the outbound container in ABAP to send the values to JAVA.
3. Sync the container to the backend.
At the ABAP end :-
4. Loop at the inbound container and extract these values from it using the fieldnames.
Cheers.

Calling Java program from ABAP

Hi All,
my ABAP program downloads one file to one folder. Then one Java program is running to Encrypt the file.
Now , they want to call the JAVA program in ABAP, so that they can encrypt the file before downloading.
Is it possible to call a Java program from ABAP ? If Yes, please give me the detailed procedure.
Thanks
pabi

Pabi,
Using the RFC connection,we can establish a link between Java and SAP.
Afterwards,hope we can call Java program from ABAP.
Below is the sample piece of code to establish RFC connection(link) between Java and SAP.
DATA: REQUTEXT LIKE SY-LISEL,
      RESPTEXT LIKE SY-LISEL,
      ECHOTEXT LIKE SY-LISEL.
DATA: RFCDEST like rfcdes-rfcdest VALUE 'NONE'.
DATA: RFC_MESS(128).
REQUTEXT = 'HELLO WORLD'.
RFCDEST = 'JCOSERVER01'. "corresponds to the destination name defined in the SM59
CALL FUNCTION 'STFC_CONNECTION'
   DESTINATION RFCDEST
   EXPORTING
     REQUTEXT = REQUTEXT
   IMPORTING
     RESPTEXT = RESPTEXT
     ECHOTEXT = ECHOTEXT

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 stack and ABAP stack in upgrading SP

Hi,
pls pardon if it appears silly question. I dont have much knowledge in Basis
I am on XI3.0 with SP 09 and upgrading SP to SP20 from SAP service market place.
How can I identify which is java stack and which is ABAP stack in evrery SP because Java stack can be directly upgraded to SP20 but ABAP stack has to be upgraded one by one (like sp 01..10..11..finally sp20).
Could you pls let me know, from the list of files how can I identify which is ABAP stack and which is java stack ? so that I can first update the ABAP Stack one by one and then move to javastack
thanks,
Dushanth

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.

Hi,
Step step description here is not possible.
It always advisable to go to service.sap.com/instguides.
slow and steady wins the race.
good luck.
It's advisable to have quad processor with atleast 8GB ram.
If it's a nw04s then at a shot you can select AS ABAP. JAVA, EP, PI(XI) and proceed.

Webdynpro Java and Webdynpro ABAP

hi all,
Im working in webdynpro java. Im confused about WD java and WD ABAP. which one we should select for what? And now a days people are telling that SAP is coming up all business packages in WD ABAP. Is it true? Which one is better either WD Java or ABAP?
Thanks,
J.Smitha.

Smitha,
It's tough question to answer. Which one to choose either Web Dynpro java or Web Dynpro ABAP , it depends on which technology you are comfortable. In relation to the business packages SAP already provided allmost all of them in java and in the future all the Business packages also available in ABAP. It's all how you want to develop the application. In sap portal world some applciation which we can develop with ABAP Web Dynpro and some applications with JAVA Web Webdynpro as SAP Web AS available as dual stack.
If someone already has a strong ABAP background and has WD for ABAP available they should probably use that. If they are a J2EE developer they should probably use WD for Java but it is likely they will also then need some ABAP support for the backend systems.
I think more customers may be asking for WD for Java projects simply because it has been around longer and is more widely available to customers where as some cutomers prefer to develop their application using ABAP Web Dynpro because of SAP propritary. But ultimately it's again all our interest and customer.
Thanks

How to write c or c++ or Java languages in abap

dear sir,
i want to capture the screen and attach with mail content while creating the support message in R/3 system .. i dont know how to capture the print screen button in ABAP .. but i know in C , C++ and Java . i am having that code .. now i want to how to embed that code in ABAP editor .. Whether it is possible or not ..
Please reply,
Regards,
kumar

Hi kumaresan,
though you can compile and execute JAVA script from ABAP , there is no compiler provided in ABAP for C / C++. You can have a look at the class - CL_JAVA_SCRIPT.
if you are trying to capture and send a particular screen shot - possibly you need to create a ActiveX control - which will capture the screen and create the image file for you. And at the same time it needs to pass back the binary streams for the image. SAP allows external call to Activex controls via OLE framework ( u ll getsamples for calling Excel, Custom Container etc ). may be u can try at that line.
Bottom line is if you r looking for C, C++ or Java compilers inside ABAP - i am afraid - its not possible..

JCo Outbound( calling Java Function from ABAP )

HI,
I want to call a JAVA function from ABAP.I have installed the JCo toolkit and included the sapjco.jar file in the classpath of my system.
When i execute the program(Example5.java,provided with sapjco.zip) from the command prompt,it is working fine,the server listens to the calls made from ABAP via RFC destination.
But if i copy the same program in NWDS in a JAVA project,to run it from there as JAVA application,after including the sapjco.jar file in the project JAVA build path,i get the following error,marked by a red cross ,at the head of the program,even before i run it.
<b>This compilation unit indirectly references the missing type com.sap.jdsr.writer.DsrIPassport (typically some required class file is referencing a type outside the classpath)</b>
What changes do i need to make,to run it from NWDS?
I tried to include the sapjcorfc.dll file along with the sapjco.jar in the java build path,but it doesn't help.
Please tell how to solve this issue?
Regards,
Siddhartha

hello sid,
which jco version are you using?
are you using the same jco lib when running in command
line and in nwds?
if you are, try checking the order of the your classpath.
your jco lib (which you are using in command line) should
come first in order prior to the default libraries in your project.

jo
