ABAP Java connectivity

Hi ABAPers,
I want to have a sample program for SAP Java connectivity. I know SAP has a JCo but how to go about it. We have another system which needs to communicate with SAP 4.6C. Also, I would like to know whether while reading tables from other system, can this program update our tables.
Thanking you.

Hi,
To use JCo, download it (including the Javadocs) from http://service.sap.com/connectors. The zip file contains a comprehensive tutorial to program using JCo. You can also take a look at the FAQ on JCo at http://www.sapgenie.com/faq/jco.htm for more information.
If you just want to take a look at the sample code, you can download the tutorial from http://zerone.samcheok.ac.kr/Asp_pr/Language/.%5Cuploadfile%5CJCo%20Tutorial-1.pdf
You can definitely use JCo to update tables in SAP. You will either have to call an existing BAPI, or an RFC FM to do so.
Hope this helps. Let us know if you need further assistance.
Regards

CRM (Abap + Java) connect with WAS (Abap + Java)

Hello collegues,
i have installed Netweaver 7.0 with Enterprise Portal.
Now i must connect
WAS with CRM system, but i do not what i have to connect ABAP - ABAP parts (RFC connection type TCP) or Java - Java parts (in visual admin in JCo) or ABAP - Java ( no idea how)? Which users are using for?
The second task -
i have tryed to create some user in portal but got message "error in persistence"?
In useradmin in EP i saw that standart users from R/3 Abap are there. May be i fogot to set something after installation?
Thank you very much for any idea.
Julia

Hi Julia,
for CRM you don't need to "connect" the Portal (Java) with the CRM (ABAP) system.
It is "just":
- import of the CRM Business Package
- definition of a system in the portal pointing to the CRM
- setup of SSO (if you want SSO)
The error with the persistance:
You already have connected the Java UME to the ABAP system. In the ABAP you have a user called "SAPJSF" - this user has only read permission on the users. You have to assign another role to that user: SAP_BC_JSF_COMMUNICATION instead of SAP_BC_JSF_COMMUNICATION_RO

ABAP+JAVA - Java-addon does not seem connected

Hi,
I messed around with this new system a month ago and now that I finally got back to it the JAVA part don't seem to be working or the SCS instance is not connected to the Central Instance.
The SCS instance seems to be running fine.
Some questions:
1. In t-code SM51, should you be seeing any reference to the SCS/JAVA instance?
2. The <b>Central Instance number is 08</b>. The S<b>CS number is 10</b>. So I should be able to connect to the java part by browsing to http://hostname:51000 or not? (I get a page cannot be displayed)
3. When I for example trying opening the Solution Manager Diagnostics from the SAPGui the Internet Explorer window that opens try to browse to http:/hostname:8008/xxxxxxxxx . Should it not go to port 51000?
4. Is it correct that the Default parameter rdisp/msserv_internal = 2008 and that the SCS instance one = 3910?
5. Any other advice or ideas on how I can troubleshoot this?
Many thanks!

Hi,
some answers:
1. No
2. no. On the Java SCS only Java Message Server and Java Enqeue Server are running. Try http:/host:8108/msgserver you should get an answer from the Java Message Server because its http port is 81$$
3. not neccesaryl. In an ABAP+Java System the ICM distributes HTTP request between ABAP and Java world. 80$$ is the default http port if ICM. Without any URL prefix the ICM should redirect to the Java Dispatcher. When the URL has a prefix starting with sap, e.g. http://host:8008/sap/public/info its going to the ABAP side.
4. you find default ports at http://service.sap.com/security > Security in Details > Infrastructure. There should be a pdf called TCP/IP ports used by SAP software or something similar.
5. what do you want to troubleshoot? Everything seems to be fine

Sascha

AS ABAP & AS JAVA Connection

Hi,
I had installed ABAP on different host with different SID and JAVA on a different host with different SID.
Please if someone can help me in setting up the connection between ABAP & JAVA Engine so that in SMICM, it shows J2EE Engine configuration true and Operational True.
Regards
Malay

Hello, this is not possible. If you install a java system on a different server with a different sid as the abap system, the smicm is not involved for starting/stopping the j2ee. only if you have a addin installation. in your case stop/start java and abap seperate.

Abap-java stack connectivity

Hello,
i have a BI 7 system - abap+java stack
the java stack is supposed to be configured to work against client 001 in the abap system
apperently this is not the case
usually it is configured from the http://<host>:<port>/nwa ->identity management but i can't login to the java/portal - the login screen is jumping again and again no matter which user name i put
can anyone advise where is the java client in the abap stack (usually 001) is configured?
Regards,
Moshe

Hi,
Yes for default Central Services Installation the java stack will point to 001 client.
Just check the certificate in the key store(in visual admin), this error generally occurs when the certicate gets expired. If it is the case then delete the certificate and create an new one then import the certificate in the abap stack.

Vamshi.

SSO To J2EE engine of ABAP+JAVA Addin Install

Hi all,
I have setup an SAP system as a ABAPJAVA Addin Install. The system is running NW04s SP11. I have an SAP Portal installed on the JAVA side to support some BW functions. I would like to do SSO from the users desktop directly to the portal component. Is this possible with this type of install? I have setup Kerberos / SPNego with a JAVA only install connected to a Microsoft ADS. I have also configured the system to use MYSAPSSO2 tickets from another SAP system, but that requires the users to go to the other SAP system before going to ABAPJAVA Addin system. I would like the users to go directly to the ABAP+JAVA Addin system via a URL like http://server:port/irj/... and get single signed on to the system. Is this possible?
Any help is appreciated!
Russ Scherbarth

Hello Russ,
yes it is possible to configure SSO using SPNego Loginmodule (Kerberos) for this type of system as well. You also can use the SPNego configuration wizard to get the configuration work done, but you need to perform some manual follow up work as well.
So my recommendation is check the online documentation for wizard based configuration AND manual configuration, perform the wizard based configuration (more or less the same as you did for the other system) and afterwards (depending on your JDK) you might have to perform some manual follow up activities.
Select as user resolution mode prefixbased, the attribute to be used is uniquename. In addition you need to create the service user in the portal database (when using SUN JDK), as you do not have direct connection to Active Directory.
With best regards,
René

NWBC 2.0 logon failure to ABAP/JAVA stack system

Hi,
Maybe not the correct forum, but there isn't any for the NWBC.
I am testing the Netweaver business client 2.0. It seems to work fine for portal connections, but when i try to connect to a netweaver system (abap+java) using the internal ITS url (http://host:8000/sap/bc/gui/sap/its/webgui), i get an error saying:
Could not open the logon window on server <host> (server URL http:// <host>:8000/sap/bc/gui/sap/its/webgui, logon URL http://<host>:8000/ticketissuer/TicketIssuer?NWBC_avoidCache=460486210'); check if the URL is valid and the server is running
The URL works fine on the NWBC 1.0. Is there something significantly changed in 2.0? Does the 2.0 version only accept portal URLs? I can't find any documentation on this.
regards,
Bas

hi,
There might be problem in Properties in the Connection Sections
Also see the below documentation as i dont know what parameters you might have given for configuring.

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

Change IP address on ECC6 (ABAP + JAVA stack)

Hi all,
we need to change the IP address of our server running an ECC6 with double stack (ABAP & Java). Also the DB is in the same server (it's a Demo IDES system).
The computer's name will remain the same as previously.
In the HOSTS file we have updated the new IP address.
Are there some other manual corrections needed ?
Is ther something to be adapted in the J2EE admin of config ?
Thanks in advance.
Andrea

I have looked into OSS note:

Link User Management ABAP-Java Stack

Hello everybody,
we have a WAS 6.40 ABAP+Java running. In client '000' if i create a new user, this user is also available at the java stack of the WAS. But if i create a new user in client 'XXX' (a copy of the client '001') it does not show up at the Java Stack. So there has to be some customizing settings i missed to set. Anyone can give me a hint?
thx
Markus

hi.
First you'd better not use client 000 when install java engine.
u should copy a client from 000, when intallation
java engine, use this client, when ask you to input client and ddic password.
But if you have do so, just copy the client. and maintain the configuration in Visual Administrator.
1. In the left frame choose Server - Services - Configuration Adapter
2. In the tab Display Configuration (right frame) choose Switch between view and edit mode to activate the edit mode.
3. Choose cluster_data- server - cfg - services - Propertysheet com.sap.security.core.ume.service
4. Choose Show the detail of the selected node
5. The parameter ume.r3.connection.master.client must be set to your SAP ABAP client. Adapt the value if
necessary.
wish it helps
best Regards

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 .
