2004s BI Portal (BI-Java) and BI-ABAP: doublestack vs. separated stack

Hi specialists,
We plan to migrate our NW2004 System (no Portal in use) to NW7.0.
For the NW7.0 Portal Architecture we are not sure what to choose:
- BI-ABAP and BI Portal (BI-Java) on the same instance (doublestack)
- BI-ABAP and BI Portal (BI-Java) on seperate instances (separated stack architecture)
Medium term we assume, that the portal is used for Web-Reporting and integrated planning. The development of applications (Java, Visual Composer) will be the exception.
But if our reporting requirements changes and the number of own applications is increasing?
Which is the best possibility to be future-proof?
- Is it possible to separate the doublestack architecture later?
- Is it possible to "transport" Portal stuff/applications from a doublestack system to a separated stack system?
- If the number of Portal-applications is increasing, is it an opportunity to set up an additional BI-Portal which is connected to the doublestack BI system?
Thanks for your help.
Regards
Karin.

Hi
Too many questions .But its interesting.Ok lets take one by one.
You can have either of the options depending on the amount of data and your hardware.
I would suggest if you have the hardware go for seperate machines for each kind of installation.I mean have a BI system((dual Stack) + Portal or you can have portal on a seperate machine also.Then you can have another portal (single stack).And using the FPN(Federated Portal Network) concept you can actually implement ur scenrio.
Note :BI-Java cannot be installed seperately you need a portal for it.
Yes FPN can be used to transport the data from one portal to another.To the last questioin i have already answered ,its better to go for a seperate BI system.
Any other doubts feel free to ask:

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
Ajay

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 configure the connection between AS JAVA and AS ABAP

Hello,
I have installed a SAP Netweaver 7.3 AS JAVA and I would like to connect this JAVA Instance with 3 ABAP Systems (ECC 6.0) .
On help.sap.com I have found the following instructions: http://help.sap.com/saphelp_nwpi71/helpdata/en/3b/0c4b428f96ab53e10000000a1550b0/content.htm
Could you please advise, if the above configuration steps are OK?
Or could you please help me with the exact procedure?
Thank you in advance!
Noemi

Noemi,
I'm not sure how exactly you want to use ABAP and Java so it is hard to answer your question.
The link that you posted describes the steps to configure ABAP as a Security Assertion Markup Language (SAML) service provider. As a service provider, the AS ABAP enables you to off-load the authentication of users onto an identity provider. The identity provider enables you to federate identities across domains for Single Sign-On (SSO).
Check the following wiki page for a good overview of all the ways that you could connect to ABAP

One JAVA and multiple ABAP Instances

Hello All,
Till now i have done configurations for Billerdirect on one Java instance and one ABAP instance.
Now my situation in production we have multiple ABAP (1 CI + 4 Dialog) and only one production Java instance.
So in XCM configuration using method group_connect i have created XCM configuration this is working fine.
so here is our problem after doing this .
For self user Registration we have created JCO_RFC_Server in XCM this configuration is working only in one situation.
Since JCO_RFC_SERVER can be created only for one instance when ever self user registration goes to other instance it fails , which is happening frequently
Can anyone please help me understand in creating XCM configuration for multiple ABAP instances so that i can create multiple JCo_RFC servers.
Over View:
From one Java instance i want to establish multiple connection to ABAP (CI + DI) so that i can create one JCO_RFC server for each connection.
When i want to access system i will access using XCM connection name at the end.
eg some thing like this.
http://myserver:53000/bd/public/frameset_top_html.jsp?SYS=MYSYS1
http://myserver:53000/bd/public/frameset_top_html.jsp?SYS=MYSYS2
Please help in moving forward.

Open connections between AS Java and AS ABAP when using JRA

Hi, we have a problem with open connections and hope that someone here could give me hint where to find a solution.
The situation is that we open a connection from a Java application to an AS ABAP. In detail, the application first connects to a statefull session bean on the AS Java by RMI. The bean communicates with the associated AS ABAP by the Java Resource Adapter (JRA).
All interactions between all components work correctly. But even after we close the application, manually close of the connections (on side of the AS Java) , remove all created and used session beans there are still open connections between the AS ABAP and the AS Java.
The transaction smgw (Gateway Monitor) shows open connections from jlaunch to our local SAP gateway using the internal communication protocol. Obviously, the established connections are not closed, even when they are open for a week or longer.
After opening 100 connections, the AS ABAP denies additional connection attempts.
We have been able to close all open connections by restarting the AS Java or by restarting the Connector over the Visual Administrator (path: Cluster Server Services Connector Container select the right connector stop / start).
We have developed our application similar to the tutorial from [https://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/docs/library/uuid/ad09cd07-0a01-0010-93a9-933e247d3ba4]
Can someone explain to us why the connections stay open for so long? Is there no timeout mechanism? Or is there some way to close the connections from our Java application?

Hello,
maybe someone can help us with our problem.
We have developed our application similar to the tutorial from https://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/docs/library/uuid/ad09cd07-0a01-0010-93a9-933e247d3ba4 and it was running without problem with the SP12, now we change our system to SP16 and we are having the problem described in note 1083348, but as you can see, for us it was working with SP12 and now it doesn't work with SP16....
Here is part of our code....
    public List getAll() {
        String functionName = "bla";
        try {
            openConnection();
            MappedRecord response = (MappedRecord) interaction.execute(null, request);
            MappedRecord record = (MappedRecord) response.get("E_S_RETURN_CODE");
            if (((String) record.get("RETURN_CODE")).equalsIgnoreCase("E")) {
                throw new SQLException((String) record.get("RETURN_TXT"));
        catch (ResourceException exc) {
            throw new EJBException(".");
        catch (SQLException exc) {
            throw new EJBException(".");
        finally {
            closeConnection();
    protected void openConnection() {
        try {
            connection = connectionFactory.getConnection();
            interaction = connection.createInteraction();
        catch (ResourceException exc) {
            interaction = null;
            connection = null;
            throw new EJBException(getExceptionText(exc));
protected void closeConnection() {
       try {
            if (interaction != null) {
                interaction.close();
            if (connection != null) {
                connection.close();
        catch (ResourceException exc) {
            throw new EJBException(".");
With that code we are getting this error: "Connection handle is already closed and no longer associated with a managed connection" everytime we try to close the connection in the method closeConnection().
We were thinking that maybe we should not close the connections, because the were already close, and tried not to close the connection (connection.close()), but then after a few time we are getting the following error, because we are not closing the connections:
Connection to ABAP System could not be opened, because the Connection Factory returns "Cannot get connection for 120 seconds. Possible reasons: 1) Connections are cached within SystemThread(can be any server service or any code invoked within SystemThread in the SAP J2EE Engine), 2) The pool size of adapter "eis/..." is not enough according to the current load of the system or 3) The specified time to wait for connection is not enough according to the pool size and current load of the system. In case 1) the solution is to check for cached connections using the Connector Service list-conns command, in case 2) to increase the size of the pool and in case 3) to increase the time to wait for connection property. In case of application thread, there is an automatic mechanism which detects unclosed connections and unfinished transactions.". Please check the connection defined for the Connection Factory of the Java Resource Adapter with JNDI name...
Any help?

Start both Webdynpro JAVA and WebDynpro ABAP from UWL

Hi all:
We are facing a situation. We need to start both JAVA dynpro and ABAP dynpro applicaiton from uwl. The JAVA dynpro application is the ESS absense request. And we also developed other workflow which use ABAP dynpro as work item . The problem is when we regist our ECC system to UWL, the system can only provide WAS java information or WAS ABAP. So there are alway one type of our work items can't start correctlly. How can I modify the UWL configuration to meet our requirement?
Anyone knows please notify, thank you very much!
Wayne

Hi,
when you try to register backend system , you will choose system alias which was already existing in the portal which has WAS hostname and port.
that is sufficient. Based on visualzation parameters , you can launch webdynpro abap/java tasks.
check below article

Abap+java stack for Portal 7.0 and MI - User Data Source

The SAP pre-requisites for Portal and MI (Mobile Infrastructure) 7.0 is an ABAP and Java Stack. If you install an AS ABAP + Java, the UME is automatically set up to use the ABAP user management of the same AS installation. What does this mean? The user store will be created in ABAP, for both the Portal and MI.
The impact of this is portal users management is in ABAP. This configuration by design cannot be connected to LDAP Active directory for user authentication.
Please let me know , if some body had already face similar issue and come up with the solution. Thanks in advance.

Hi Surya ,
When you install portal or any NW component with ABAP stack , ABAP stack hold precidence over the JAVA Stack , refer to this link to have more idea on this .

Integrated planning in sneak preview of java and abap versions of nw 2004s

Hello all,
I installed both AS ABAP and AS JAVA of the sneak preview netweaver 2004s,but unable to run integrated planning.I searched the forum and sap notes but did not find specific required steps to configure.Anyone able to run integrated planning of the preview versions ? does it involve extensive configuration ? Could someone post the necessary steps to configure.I checked the SLD and it is running but did not have any 'technical systems' configured.I created a technical system for ABAP and JAVA manually myself.The jco destinations still shows 'No SLD connection' with a red button beside it.
Then I went to visual administrator and checked SLD data supplier service.It looks like it is lot of BASIS work to configure this.Please let me know if someone has simple steps to configure and run integrated planning just after installing sneakpreview versions of nw 2004s ABAP and JAVA.
Thanks

ABAP mapping
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.

Steps required for developing XSLT Mapping
u2022 Create a source data type and a target data type
u2022 Create Message types for the source and target data types.
u2022 Create Message Interfaces includes Inbound Message interface and Outbound Message interface.
u2022 XSLT Mapping does not require creation of Message mapping, so donu2019t create any Message mapping.
u2022 Create an .XSL file which converts source data type into target data type.
u2022 Zip that .xsl file and import it into Integration Repository under Imported Archives.
u2022 In Interface Mapping choose mapping program as XSL and specify this zip program. (Through search help you will get XSL Mapping programs that you imported under Imported Archives, select your corresponding XSL Program)
u2022 Test this mapping program by navigating to Test tab.
By having look at above steps you can easily find out that this mapping is no where different from other mapping programs, here the challenging lies in creating an XSLT file. If you spend couple of minutes in studying XPATH tutorial you would be in ideal position to create an XSL Transformation (.xsl extension).
If you still find difficulties in generating XSL Transformation, then you can make use of a tool u201CAltova MapForceu201D which will create XSL file for you.
Steps for creating XSL file using this tool:
1. Open the Alto MapForce, import the source .xml and .xsd file in it
2. Similarly import the target .xml and .xsd in MapForce.
3. These two data files should match with source and target data types in Integration Repository.
4. Complete the graphical mapping using extensive list of XSLT functions available there.
5. Save the mapping file.
6. Click the XSLT tab. You will have the entire xslt logic there.
7. Copy that content and save it as .xsl file.
8. Zip above .xsl file and import the same into IR under Imported Archives.
Hope this clears your doubts
Thanks

Check the relevant services are test are active on the Backend system through SICF trransaction.
Also make sure that default icm services are running.See note 517484.
More important the connector test in the portal system should work properly,recheck the WAS path etc are correct.
