ABAP STACK and JAVA STACK certificates

Hi Fiends,
I have requirement in which I want to use HTTP adapter to send message and apply security certificate. I got from sdn that if I wan to use http adapter with certificate than I have to install certificates in ABAP stack.
My problem is I had one scenario in which I am using BC adapter to send message with security certificate and for that I had applied certificates in java stack and its working properly.
My question is,
Is it possible to use Java Stack and ABAP STACK together..?
I mean is it possible to implement both of the above scenario in same xi system?

Hi Soni,
You cannot use the same certifcates wihch you installed in Java stack with abap stack. You need to install separealy on teh abap stack.
For HTTP communication you dont need to install certificates. You only need when you want to use HTTPS communication. So if you want to use HTTPS communication and want to use SOAP adapter then you can use ther certifcates which is already installed on java stack. But if you want to use HTTP adapter then you need to install in ABAP stack.
Please see this hlep on how to install on the java stack and the process behind it:

PI Pipeline Doubt : Pipeline Steps in ABAP stack and JAVA stack

Hello
Can anyone please assist me with which stages steps of the PI Pipeline are executed on the Java or the ABAP stack.
Receiver Determination
Interface Determination
Message Split
Message Mapping
Technical routing
Call Adapter
Also can anyone please provide links relating to the PI architecture diagram describing it from ABAP and Java Stack Perspective and not from the Components perspective i.e. Integration Repository and Directory.
Thanks.
Kiran

Hi
Tha ABAP stack consists of the Integration Server which in turn contains your Integration Engine and Business Process Engine.
The J2EE stack contains the Adapter Engine and your IR and ID run on the J2EE engine.
Most of XI pipelines happens in the ABAP stack.
All messsages picked by the Adapter Framework running on the J2EE engine are passed to the Integration Engine, which does the routing. The mapping program again gets executed on the Java stack and the rest of the pipeline servies are executed again on the ABAP stack and so on.
Message, Java & XSLT (under Imported Archives) mappings are executed at Java stack;
ABAP & XSLT (in ABAP stack) mappings are executed at ABAP stack.

to configure acceptance of the ABAP (integrated ITS / WebGUI) saplogonticket on the java stack, just log into the java stack (http://FQDN:50xxx/nwa) and select configuration THe last item in the list is Trusted System... click.
on the ensuing page, click on the add trusted system button --> by querying trusted sytem.
Enter the required data on the page:
system type: ABAP
host name: FQDN
System Nr: your instance number
client (of the productive client)
and a username and pw with superuser priveliges in the system (SAP_ALL/SAP_NEW, etc).
the click next
On the final screen, click finish.
You have now SSO setup between the ABAP and Java stacks. To configure SSO to accept java saplogontickets on ABAP see:

This should resolve your question.

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

Where to see the abap stack and java stack.

Hi..
I have installed ECC6.0 ABAP+JAVA engine.
I would like to know the stack level of my system. for this how i have to check. If so please mention the path how to check, Is there any R/3 level command or O/s level command to check these stack status.
Previously TCODE SPAM is used to see the Support Pack level of ABAP or Basis or any other OCS packages.
I would like to know the difference of the stack level and the support pack.

Deleting error messages in ABAP stack and JAVA stack

Hello,
found some useful answers here about deleting messages
which are successfully delivered!
What I miss is an answer about:
a) Error messages in RWB
In Component monitoring -> Archiving you can plan a job to delete messages in status "successful" or "Cancelled with errors".
To cancel jobs you have to do this one by one. With reaction time from page manual cancellation needs hours for 100 messages (Ok, there is a multiple selection button you can use to tag per list screen!).
Now I have lots of message here
- System error
- to be delivered
- cancelled with errors (from system, special case, see next question)
ready to be erased (yes, sure about that!)
Is this the only way here to proceed?
Other question: looks like there is a default time frame for the job which looks like it is more than two months for "successful". "Cancelled with errors" is only deleted from list when reaching this status with the available button "Cancel" but not for messages with status "Cancelled with errors" set by the system.
Any chance to change that time frame.
And what about the messages "Cancelled...." by the system?
b) ABAP stack
OK, delete job is running. But looks like there is a default time frame "delete older than 2 months" (different from a! where it is more than 2 months)
I tried to delete some error messages with function "Cancel message with errors".
Now these messages are cancelled in SXMB_MONI (displayed with different status sign "Pencil").
Starting deletion job has no effect on them. Why? Because they are cancelled today and are not considered by the time frame of the deletion job?
Any help is appreciated!
(This tool is confusing me more and more! )
Hm, looks like nobody knows about this issue?
Regards
Dirk

Hi Dirk,
I am also facing the issue for deleting the messages with errors or if i have cancelled them.
Did you find any solution for these issues. Kindly let me know if you have find out any solution.
thanks

Abap and java stack together gives error message...

I am trying to install abap stach and java stack together.
I installed abap was without problem but when I install Java i get the error below.
I tried SP09 and since it didnt work Sp07 also since I had it with me downloaded before.
Any help ??? Got stuck
I need to install together to practice webdynpro...

THis error was gone when I used the registry cleaner for removing ABAp stack But now question is How do I install BOTH????
May be the instance number is the problem....
In old version of ABap stack we can enter the instance number .But not in SP 9 .Can we change here too?

This file holds the Key of the errors since it checks for the instance number which is given in the log as details.. May be we can change it....
In ABap STack install instead of files as in SP 07 they have created an image and may be this si the reason that
we cannot customize.I have to find a way in order to install it...

i found soltuion myslef THe lates WAS for abap is preconfigured and so its not suitable for abap-java multiple installation

ABAP aND Java Stack

Whats the use of an ABAP and Java Stacks in XI? What exactly they are doing for XI?
Thanks.

Hi,
Tha ABAP stack consists of the Integration Server which in turn contains your Integration Engine and Business Process Engine.
The J2EE stack contains the Adapter Engine and your IR and ID run on the J2EE engine.
Ever wondered how and where the XI pipeline gets executed? It happens in the ABAP stack.
All messsages picked by the Adapter Framework running on the J2EE engine are passed to the Integration Engine, which does the routing. The mapping program again gets executed on the Java stack and the rest of the pipeline servies are executed again on the ABAP stack and so on.
Take a look at the XI overview doc to understand this better,

How to connect separated ABAP and Java stacks ?

Hi,
I have installed two separate ABAP and Java Stacks and trying to connect both the stacks together.
As per my understanding, only JCO RFC is the mean of communication between ABAP and Java stacks.
But still even after configuring the JCO RFC successfully, I am unable to view, configure or control
J2EE stack's status from smicm (ABAP).
Would you please suggest me, if there is any more configuration to be done on abap or Java stack side.
Thanks,
Cheers !!!
Ashish

Hi Sunny,
JCO RFC is tested and it is working fine. So no issues from JCO RFC side. Hope you would have read carefully.

Hope I am able to clear your doubt. Java is completely separated stack and not add-on.
Suggest me how can I proceed further on this connectivity.
=========================================================
Hi Olivier,
I am grateful to you for your reply. I understood your point but now except a successful JCO RFC test,
is there any mean to check and ensure that both the stacks are connected properly and ready to use.

ABAP and Java Stack: Which to choose/supported standards and components?

Hello,
I am trying to understand the role of the two stacks in NW. Maybe anyone has a few
hints where I can find answers to the following questions:
- An overview of supported Standards (Java 5 since when?)
- An overview of which component runs on which stack? Portal->Java, Integration Server->ABAP and so on.
- Guidelines when to install both stacks and when to use just one stack? When do I use which one?
- Has SAP an stategy towards an one Stack solution (possibly Java?)
Best regards and thanks for any pointers!
Stefan

An overview of supported Standards (Java 5 since when?)
Go to service.sap.com/pam
Product Availability Matrix will tell you about supported version and platforms.
An overview of which component runs on which stack? Portal->Java, Integration Server->ABAP and so on.
Usually the question goes the other direction: what stacks we need for implementation of a particular function?
More and more products require ABAP backend and Java frontend.
For example Employee Self Service has been transerred from ABAP only ITS based to ABAP backend and Java frontend.
Same with SRM.
Guidelines when to install both stacks and when to use just one stack? When do I use which one?
Same as above, driven by business requirements, not technology.
Has SAP an stategy towards an one Stack solution (possibly Java?)
No. Core business functions are still being developed on ABAP and interface, GUI etc utilize JAVA.

Slava

Individual business system for ABAP and Java Stack

Hi All,
I need to send message from a system to XI via ABAP proxy and Java proxy. The sender's ABAP and Java proxy use the same message interface to communicate with XI. Should I create one business system for the ABAP stack and one for Java stack of the sender system?
Thanks + Best Regards
Jerome

Are you sending same message type from ABAP proxy and Java Proxy to XI?
If you have ABAP proxy, why do you need Java Proxy? Actually you cannot create any Java proxies on ABAP bases systems. What kind of system sender is? Java proxies are created for pure Java based applications.
Let me know if I didnt understand your question correctly. If so, please explain in detail why you need both proxies and what is your sender application.

HTTP Post and Java Stack

Does the java stack need to be installed for ECC5 to send a message via HTTP?

ECC is can send the data through ABAP Stack , No java stack required.

Any problem if we areon ABAP SP12 and JAVA SP09 for PI 7.0

Hi All,
I was wondering being on different ABAP and Java SP's could cause any problems or compatibility issues in PI 7.0.
We are on SP12 for ABAP stack, SP09 for JAVA stack.
We are getting the following error (Red LED: Test Returned an Error) in Self-Test Status for BPE (RTW --> Component Monitoring --> Display --> Business Process Engine):
Details for 'Schedule Background Job for Packaging'
Background job for packaging is not required
Details for 'Schedule Background Job for Reorganization'
Background job for packaging is not required
In details it says background is not required and it gives Red LED in test.
Please let us know if anyone has any idea about the above two issues.
Thank You,
Indrasena Janga

Hi,
>>BPE (RTW --> Component Monitoring --> Display --> Business Process Engine):
To my knowledge different patch levels on ABAP and java stack will not cause this issue.
More over there will not be much issue when we use different patch levels on ABAP and java stack

Displaying both ABAP webdynpro and Java Webdynpro tasks in the UWL

Hi,
We have two an issue when trying to get the UWL to process two different types of workflow tasks : ABAP webdynpro and Java webdynpro.
Examples of these tasks are:
TS12300097 u2013 LeaveRequestApprover u2013 Java Webdynpro
TS17900100 - ASR_PROCESS_EXECUTE u2013 ABAP webdynpro
We have two backend systems configured
SAP_ECC_Financials u2013 This has the WAS host pointing to the java stack (xxx:50000)
SAP_ECC_Workflow u2013 This has the WAS host pointing to the ABAP stack (xxx.80xx)
In transaction SWFVISU all the tasks which use Java webdynpro have been configured to use the u2018Javau2019system (SAP_ECC_Financials) using the SYSTEM_ALIAS parameter
In the UWL configuration the system SAP_ECC_Workflow has been registered
In addition to this all u2018Javau2019 tasks have had an extra UWl config XML created to ensure that the SYSTEM_ALIAS is set to SAP_ECC_Financials
The system SAP_ECC_Workflow has been re-registered
The UWL cache has been cleared
However when we try to launch the java webdynpro tasks the system is trying to access the ABAP stack (It is still trying to access the Web AS location for the system SAP_ECC_Workflow even though the system alias was specified as SAP_ECC_Financials )
The ABAP webdynpro tasks (in this case a HCM process and form) are launched correctly
If we try the reverse (i.e register the Java system SAP_ECC_Financials and change the SYSTEM_ALIAS parameter for the ABAP webdynpro tasks to system SAP_ECC_Workflow) then the reverse happens. The java tasks can be launched and the ABAP tasks cannot.
Does anyone have a solution to this problem. Surely other people have implemented both ABAP and Java webdynpro workflows?
Any help much appreciated
Andrew

Thanks a lot for all your replies..
The workitem type registration has been done already, but still it doesn't work..
But here is the actual problem...
There is a link 'Execute Workitem' in the inbox of the approver, or the second level manager...
In the leave application, when we click on this link it is taking to the portal as the task is the Webdynpro Java application task. Whereas, when using ABAP webdynpro application task, it is taking to R/3 - which means that the user cannot access this link without R/3 access. The users are given only portal access, they don't have access to backend R/3.
The requirement is that the link has to take the user to portal directly instead of R/3 - i.e it should ask only for the portal id and password.
Since it was working fine with leave application, I changed the task to Java webdynpro task, but I think the Java Webdynpro application is not deployed in the server.
Please can anybody suggest.
Best Regards,
Sushmitha
