SAP JCo Clarifications

Hi Experts,
I have installed SAP Business Connector 4.8 for one of our ECC 6 EHP 4 systems (without AS JAVA) and maintained all the settings for SAP server and listener in adapter settings. I have also maintained correct settings in SAPBC rfc in SM59. The SAPBC is working fine for the xml documents. The client also wants an external Java application to be able to call up the SAP system for business reasons. Now in help.sap.com page "http://help.sap.com/saphelp_nw04/helpdata/en/6f/1bd5c6a85b11d6b28500508b5d5211/content.htm" its written that "SAP JCo is automatically installed when you use SAP Business Connector or SAP Web Application Server for Java." Since I have already installed SAP BC, the JCo should have got installed automatically (I checked LD_LIBPATH, no entry for jco path there, also no classpath is set). How do I check whether this has happened or not? I am dealing with JCo as well as BC for the first time and don't have much idea about them. When the JAVA team is trying to do some work on this, they are getting the below error:
com.sap.mw.jco.JCO$Exception: (102) JCO_ERROR_COMMUNICATION: JCO.Client not connected in repository call
at com.sap.mw.jco.JCO$Repository.getVersion(JCO.java:17820)
at com.sap.mw.jco.JCO$Repository.queryFunctionInterface(JCO.java:18148)
at com.sap.mw.jco.JCO$Repository.queryFunctionInterface(JCO.java:17881)
at com.sap.mw.jco.JCO$Repository.getFunctionInterface(JCO.java:17991)
at com.sap.mw.jco.JCO$BasicRepository.getFunctionTemplate(JCO.java:17062)
Also, I am getting the below output for the mentioned command:
sapqat01.putnaminv.com:ecqadm 210> java -jar /opt/sapbc48/server/packages/SAP/code/jars/static/sapjco3.jar -stdout
The java class could not be loaded. java.lang.UnsupportedClassVersionError: (com/sap/conn/jco/rt/About) bad major version at offset=6
We are currently running jre 1.4.2, so there is a mismatch in the version in which jco was compiled. What JCO or SAP BC version should I use in this case?
Your help is appreciated.

Data transfer b/w SAP to Java using IDOC and Interface SAP Jco

Dear Experts,
The challenging requirement we are having is, we need to create the interface for data transfer between SAP system and the Java system. The data will be transferred from SAP to java and similarly once some processing done in Java again the details needs to be transferred from Java to SAP.
For this data transferred we are planning to use IDOC process and for interface "SAP Java connector (Version 3.0.5)" we are planning to use. As per our understanding, from Java side one program needs to be written to connect with SAP as "Registered program". This registered program will appear in SAP GATEWAY automatically and using tRFC, TCP/IP connection both SAP and Java system will be connected.
In this case we are having some doubts.
1. The data from SAP is going to be transfered from one Custom transaction (Z tcode). Once "Outbound IDOC" will get triggered and will carry the details. Now the doubt is, whether the data / details will get transfered to JAVA system automatically or we need to perform any other steps from SAP ABAP coding...(like converting in to flat file, XML file and etc) ??
2. We are planning to install "SAP Jco" in Java server. Is this correct...??
3. Other than SAP Jco any other softwares needs to be installed or not..??
4. Since we are going to trigger the "outbound IDOC" from custom transaction, we are planning to develope one program in SE37. Other than this any other program we need to develop or not..??
5. Any sample Java program for the SAP Jco version 3.0.5 to create the "Registered program" with SAP..? (e.g. SAP Listener program).?
If anybody has detailed steps or explanation please share it with us.
Thanks in advance
Warm Regards,
VEL

Hi All,
For the above mentioned issue, we implemented JCo software in JAVA system and created the JAVA program including SAP logon credential details like Client, User name, password and Language details.
When this JAVA program was compiled successfully then, that non SAP system will appear in SAP gateway Tcode.
Once non SAP system started appearing in SAP gateway that means, both SAP & Non SAP are connected automatically.

Error while running the SAP JCO java program running via command line

Hi,
We are facing an issue while using SAP JCO. When i try to run the sample program using RAD 8.0 ( IBM IDE tool For Java Development) its working fine.
The same sample program if i try to run using command line, Then its giving below exception message.
Exception in thread "main" java.lang.NoClassDefFoundError: Integration
NOTE: I have configured proper sapjco jar & Dll files path in class path settings in my batch file.

Hi,
class loader can't find class definition during runtime but it could find it during compilation. So the problem is with your classpath. Does your classpath point to file with class Integration? Check this [blog|http://javarevisited.blogspot.com.au/2011/06/noclassdeffounderror-exception-in.html].

Unable to create sales Order/Inquiry object using SAP JCo

Hi All,
Pls can you help me.
I am using BAPI_INQUIRY_CREATEFROMDATA2 and BAPI_Trancation_commit to create Inquiry object.From my Client JCo code there is no error.I debugged the BAPI_Trasaction_commit, there is no error, return code is 0. But th system is not creating Inquiry object. When I try the same from SAP GUI client with exactly the same input parameters it works.
Do I need to set any option/value to commit the Inquiry to the SAP database? How to maintain the same session between the different BAPI's. Is there any issue with Session maintainance? I would appreciate if you can provide me any sample SAP JCo code for creating a Sales Order/Inquiry.
Thanks
mars

Can you put the part of your code that fill the ORDER_PARTNERS table, also you could compare your coding with [Sales order creation using BAPI|http://wiki.sdn.sap.com/wiki/display/Snippets/SalesordercreationusingBAPI] in [Community Code Gallery |http://wiki.sdn.sap.com/wiki/display/Snippets/CommunityCodeGallery] (don't forget that there is a conversion exit on the partner role, so use internal codes "AG" and "WE")

RFC calls with SAP JCO and IBM resource adapter for SAP - basic tuning

Hi experts,
we are working on a java portal connected to a backend system SAP by calling RFCs.
On our first integration tests, it appears to be quite slow fetching data from SAP by calling the remote functions from the custom portal. We are using SAP JCo 3.0.6 and IBM resource adapter for SAP 7.0.0.3 to integrate SAP with our portal.
Is there any basic tuning to achieve to improve performances or any hint of where to tune in SAP ?
Any help would be greatly appreciated.
Thanks a lot,
Jamal

Hi Jamal,
I understand you have already checked performance issues in the SAP Server. We had some problems with certain RFC calls and it turned out to be a badly developed ABAP sentence.
I'd recommend you to use httpwatch or another tool to check the response times from the browser, so you can point accurately where the is.

The Oracle JRockit JVM is not supported by SAP JCo 3.0.5.

Hello all,
I am preparing our new Oracle Fusion Middleware platforms. So far we have been running BPEL 10.1.3.4.0 and we are going to build the 11g platform (WLS and SOA suite) in parallel.
I have already installed WLS Server 10.3.3 and then SOA Suite + the SOA patchset bu selecting always Jrockit_160_17_R28.0.0-679.
Now I am abaout to install the adapters and I red in the documentation
http://download.oracle.com/docs/cd/E14571_01/doc.1111/e17054/intro.htm
For supported JVM information that corresponds to each operating system, see the SAP Note #1077727 in the SAP Service Marketplace.
Note:
The Oracle JRockit JVM is not supported by SAP JCo 3.0.5.
Is anybody aware of this? If it is valid, how could I achieve not to re-installa everything from scratch and select SUN JVM?
Could I for example create a new Managed Server where I will explicity select SUN JVM to be installed for this instance?
Best Regards,
Loukas Rougkalas

Urgent: SAP JCO vs FTP

Hi Gurus,
We have two servers(one SAP and another non-SAP) installed in our network(at two different locations). Our requirement is to upload data from a flat file(located in non SAP server) into SAP. For this, we thought of two options.
1. To use SAP JCo, installing it on non SAP server and connecting to SAP system through it and uploading the data by calling some function module using JAVA Program.
2. To use FTP transfer, transferring the file to SAP Server and uploading data from there.
Here, we have to consider the facts like performance, security, scheduling etc. As per my research I found that performance wise and security wise option2 is better than option1.
Would appreciate your inputs on this.
Thanks in advance.
Best Regards,
Lee

hi lee,
option 1 is better. Advantages are :-
E-mail Requirement:
- MAPI compatible email client (Outlook Express etc.)
- Standard SMTP e-mail server
- Exchange Server
- Outlook
- Lotus Notes
Security can be added to any PDF format. The different types of security are:
- 128 bit encryption
- Password
- Printing restrictions
- Copy restrictions
- Saving restrictions
- Editing restrictions
performance and scheduling also good so better you go with SAP JCO , its my opinion.
Thanks & Regards
