Calling JCO RFC Server program from JCO RFC client

Hi,
I have an RFC registered server program which implements JCO.Server.  It seems to be working fine, when called from SAP.
For testing purposes, I was trying to write a JCO client program which would take the place of the SAP client.
This program opens a connection to the RFC server and executes a function e.g.
JCO.Client client = JCO.createClient("xx.yy.com", "sapgw35", "MYPROGID");
client.connect();
client.execute(function);
The RFC server program receives the call fine, when I test with a simple function which has no table parameters.  However when I tried a more complex function with table parameters, I get an serverExceptionOccurred from the RFC server program:
com.sap.mw.jco.JCO$Exception: (104) RFC_ERROR_SYSTEM_FAILURE: connection closed without message (CM_NO_DATA_RECEIVED)
    at com.sap.mw.jco.rfc.MiddlewareRFC$Server.nativeListen(Native Method)
    at com.sap.mw.jco.rfc.MiddlewareRFC$Server.listen(MiddlewareRFC.java:1368)
    at com.sap.mw.jco.JCO$Server.listen(JCO.java:6805)
I have tried to initialize the repositories in both server and client programs correctly, so that the function is in the cached function list and the table structures in the cached structures list before the function is invoked.  But I am not sure if there is still something I am missing, so any ideas would be welcome.
Thanks,
Richard

JCO example 5 is a very good one for server side programming.
try the example,somethings you 'd better make clear.
1) JCO.server
2) repositories--data mapping
3) parameters: export import,table...
further topic:
1) JCO pool
2) tRFC,qRFC
After you have success in Client side programming,try example 5.
Regards

  • How to modify a code of a RFC Server Program

    Hello,
    In order to connect a BI System to a new ECC System, I need to modify a RFC Server Program.
    Please can you tell how can I modify this program?
    Thanks

    I think you are trying to run both server and client
    on one machine!!!
    It is impossible, your server is blocking the port to
    send packets, so you must run client on another
    computer!!!It's not impossible to run a client and server on the same machine just for testing or as a demo. Just have the server listen on one port and the client use a different port.
    No need to use 2 seperate computers. I've done it one computer before without a problem.

  • How to start 1 JCO-unicode-Server and 1 JCO-none-unicode-Server

    It is possible to start one JCo-Server that is unicode-able and another one JCo-Server that is not unicode-able in one program?
    I want to share one service that my Java-Program is providing for 2 SAP-Systems. But one SAP-System is a Unicode-System and the other a None-unicode-System.
    I've implemented the tip of the following site for my Unicode-System, but anyhow it does not function:
    http://help.sap.com/saphelp_nw04/helpdata/de/87/b55a4201301453e10000000a155106/content.htm
    If I start the JCo-Server for my Unicode-System first, then the communication for this system will work, but for the other, none-unicode system not.
    If I start the JCo-Server for my None-unicode-System first, then only the communication for the none-unicode system will work.
    Any Ideas??
    Or another question: How can I make the Unicode-System communicate-able with a none-unicode JCo-Server?
    Thanks for reply.

    Hi,
    i've solved my problem: I changed all my JCo-Objects in my program from from version 2.1.8 to 3.0.2.
    After that I don't needed to input information wether it's a unicode-connection or not.

  • Calling A Window's Program From Webforms

    Is it possible to call a windows EXE program (such as NOTEPAD,
    WINWORD, EXCEL, etc) from forms6.0 running on the web? This
    should preferably be calling the programs residing in the CLIENT
    PC rather than the APP SERVER machine. I tried using both HOST
    and DDE commands, but both activate the programs on the server
    side, and that these programs are shown in the TASK MANAGER but
    never appeared in focus on the screen. Can someone please help?
    Thanks.

  • Problem in calling order import concurrent program from BPEL

    Hi all,
    Iam doing a sales order creation in oracle apps using Apps Adapter.
    I have successfully inserted the order into the interface tables using an Apps adapter.
    Now I need to run Order Import program from BPEL to move the data from interface tables to the base tables for which i use another Apps Adapter.
    When I invoke the OEIMP concurrent program from BPEL ,request id is returned.But the concurrent program fails showing incomplete parameters.
    But it works when I invoke it from the front end in oracle apps.
    I think the problem lies in passing the inputs to the concurrent program from the BPEL.
    Any help to solve the issue will be appreciated.
    Thanks,
    goutam

    Previously, I was passing the values to the concurrent program variables through ASSIGN component,which resulted in some namespace issues.Then I replaced it with TRANSFORM component.
    Also,First I assigned the values to the concurrent program variables as 'Vision Operations'(operating_unit), 'Online'(order_source) ,No (validate_only), No (validate_desc_flex) which are mandatory and just left non mandatory variables without assigning values.
    I changed those values as *'204','0','N','N'*. And also set non mandatory variables value as EMPTY.
    After doing all these I found the concurrent program catches all the parameter values correctly, and the records got imported from interface tables to the base tables.Thus the sales order got created successfully.
    Thanks,
    goutam

  • Client Server program using Applets for client

    Creating a client server program using Applets for the clients.
    Having problems distrubting the message from client to client
    using ObjectOutputStreams/ObjectInputSteams.
    I can connect each client to simple server and respond with by writting

    As with the original issue, your problem is likely with the Edge server. The first thing I would do is check all of your ports and DNS settings.
    Remember that Edge may use somewhat unique ports for AV if you, or the federation target, used a single IP address. If you haven't, see if you have that unique port open on the firewall. If you used a single IP address, ensure that the federation target
    has the correct port open also.

  • How to call  Screen in another program from exsisting program

    Hello Frieds,
    Can any one help me how to call  a screen  in another program (Say "test2") from exsisting program(say "test1')
    If above case is possible then how to access the fields in the target screen?
    Your responce is greatly appreciated.
    Best Regards,
    Rakesh

    Hi Rakesh,
    If you wish to use ONLY the screen of another program, call transaction  will not help you, because the called transaction will be fully executed (and not only the screen), and the acess to screen field wil be difficult.
    When you wish to access the same screen from more than one program, you can create this screen in a function module and in this way you can call the function (to display the screen) in many programs.
    Best regards,
    Leandro Mengue

  • Problem with a call to a concurrent program from a trigger body...

    I have a table and a before update trigger on it.
    The trigger calls a packaged procedure. that submits a concurrent request.
    This concurrent request calls a packaged procedure.
    This packaged procedure inserts data into another table and then commits the insert.
    When I update the table with the trigger on it, (the above narrated scenario)....
    I come up with the error...
    ORA-04092: cannot SET SAVEPOINT in a trigger
    I didnt use any savepoint in my code.
    Any help is appreciated. Its a high priority issue.
    Thnx,
    Kiran

    You problem is that the standard PL/SQL code to submit a concurrent request (which is presumably what you are running) performs the savepoint, unless you have told it you are running from a database trigger. The processing performed by the concurrent request when it runs is not relevant to the processing of the trigger.
    We have code that submits a concurrent request successfully from a trigger, but before the call to FND_Request.Submit_Request, we call FND_Request.Set_Mode(TRUE) which tells the processing in FND_Request.Submit_Request that we are running from a database trigger and not to perform it's savepoint processing.

  • HELP!....GUI crashes when i call a multi-threaded program from it

    Hi..I have encountered a problem in my end of year project, which i cant see to solve. The problem is i am starting a multi-threaded program for a JButton on a GUI. All though this starts the other program it crashes the GUI completely how do i stop this.
    this is the code i use to call the threaded program.
    public void actionPerformed(ActionEvent e)
    Object target=e.getSource();
    String line = new String();
    if( target==b1 )
         try
    cl = new client();
         cl.startup();
         catch(Exception ex){ex.printStackTrace();}
    thanks Mike

    No there is no exceptions being given. this is one of the reasons why i dont no what to do. i thought myself that the threaded was taking all the resources and not going back to the GUI. if this is the case is there anyway that i can call back the GUI and keep the threaded program running?
    thanks
    mike.

  • Access one rfc-session-LUW from other rfc-clients - Possible?

    Hello folks.
    As the topic states, I would like to know, whether it is possible for many rfc-sessions, each opened their own session ( and therefore LUW ) to share just one, with SAP board-methods.
    I know, that I could create a proxy-software, which connects in ine RFC Session to SAP, and my other rfc-enabled clients then connect to
    this proxy, so there would be only one rfc-session and LUW.
    But assuming, I want to avoid this proxy, is there any possibility to share rfc-session-luws ?
