How to create web-screen for own-created program

Hi experts!
Could you please  suggest me:
Some of our end-users have to work with WEBGUI interface. In T-code VL02N we have our userexit SAPLZSDEXIT (Screen 0110). And in WEBGUI we don't see this tab in VL02N. I think I have to generate web-interface for this screen. But how I can make it? This screen was developed by our ABAP-ers in se51 t-code.

Lets be clear here - Web Dynpro ABAP and WebGui/ITS/SAPGUI for HTML are two completely different technologies.  If you have a WebGUI screen, you can't enhance it with Web Dynpro ABAP - if that is what you are asking for.  If your question is about WebGUI or ITS Transactions, then you are asking it in the wrong forum.

  • How to create web service for a Java class in SAP NetWeaver Studio

    hi all,
    i am using SAP Netweaver Developer Studio.have created a normal java project and i want to create web service for one of the classes in this project. i used the  Web Service Creation Wizard to create a web service for this class. but it says there's no methods available for VI. all my methods in this class are public, what should i do?

    Hi,
    I guess there are other ways. But this is an easy way, if you find the right wizards.
    Besides this it is good practise to define interface methods so that session bean implement these interface methods, and thus seperate the interface from the implementation.
    In this approach you will need 3 projects:
    An enterprise application project (will contain EJB Module)
    An EJB Module project (will contain session bean)
    A Java project (contains code that implements the session bean methods)
    In my previous post I suggested to use a J2EE web mudule project. This was a mistake, it should be EJB module.
    But it should be possible to do it in another way. It is up to you.
    Good luck, Roelof

  • Need Help to create new screen for RF Sapconsole

    Hi Guru's
    I'm new on RF (but some years in ABAP) since last week.
    I need help to create new screens for RF (SAPLLMOB).
    Can someone explain me the procedure to create screen (with ABAP code after) or perhaps someone have an exemple (simple or not) ?
    I have to develop 2 new screens with really few time.
    And, another subsidiary question :
    how SAP can transfert information between the flash gun and the screen i have developped.
    Is there some code to add to enable this functionality or it is include in SAPLLMOB on standard fields ????
    It's a new strange world for me today...
    Many thanks to everyone who can explain me
    Alain

    hi,
    I am facing this problem as well. Is there any reference to create the new screen?
    Hope someone can help! Thanks!

  • Issue in creating web service for a ABAP Function Module

    Hi,
    now i'm learning how to create web service for a ABAP Function Module. I used the following steps.
    1. select the Function Module, named "zws_test".
    2. in the context menu, select "create->proxy object". so we enter into wizard.
    3. in the wizard, press the radio button "Service Provider".
    4. in the next page, press the radio button "Existing ABAP Objects(Inside Out)".
    5. In the next page, Enter the "zws_test_prvider" as Service Definition and select "Function Module" as Endpoint Type.
    6. in the next page, enter "zws_test" as Function Module and mark the "Mapping der Namen" button
    7. in the next page,select "PRF_DT_IF_SEC_LOW" as Profile and mark "Deploy Service".
    8. Save in the local package.
    9. then it will pop up a window with title "WSDL Source". i selected "URL/HTTP Destination" and press "OK".
    10.in the next page, i enter the URL as "http://hostname:portnumber/", and press "OK".
    11. then it will pop up a window with title "Display logs". A record with error message "HTTP error(return code 404, message "Not found")" appears.
    12. i press "ok" and a service provider with name "zws_test_prvider" appears in my local package.
    13. i use "zws_test_prvider"'s URL to create a service consumer "ZCO_WS_TEST_CONSUMER" and logic portal "LP1".
    14. But when i test my service consumer "ZCO_WS_TEST_CONSUMER", it will throw an exception "cx_ai_system_fault" with errortext "SOAP:14 Unexpected element -el=definitions ns=http://schemas.xmlsoap.org/wsdl/".
    15. I use t-code SM59 to test connection  and get the following info.
          Status HTTP Response     200
          Status Text                      OK
          Duration Test Call             328 ms.
    who can give me the reasons about item 11 and 14, and explain me how to create service provider and service consumer for a Function Module.
    Thanks in advance

  • Create a screen for user input in BI

    Hi Experts,
    I want to know can i creat a screen for user input in BI with module pool programing
    and i want to store the data in ztable in SAP-BI.
    Moderator message: please search for available documentation, these forums are no substitute for ABAP training.
    Edited by: Thomas Zloch on Dec 10, 2010 8:37 PM

    I'm afraid that I cannot get it. I had a look at the docs you suggested before posting, and still, no luck (...)
    JOptionPane.showMessageDialog(dialog, "Please input info");Can you please tell me what I'm doing wrong and I cannot add the JDialog to the JOptionPane?Re-read the API and tutorial. JOptionPane is meant specifically to spare you from instantiating manually a JDialog. The showXxxDialog(...) methods do create a JDialog of their own, based on the contents supplied as arguments.
    In particular, using the 2-arguments variation showMessageDialog(Component parentComponent, Object message):
    - The first argument parentComponent is not be the dialog you want to display, but the component over which you want the dialog to appear. The most typical value are this or null.
    - The second argument is the "message" to display, but as described in the API, it can be a JComponent, that is, even a JPanel with child widgets (in a word, a JPanel containing the specific form you'd display in the dialog if you were writing the dialog manually).
    Again, at the risk of insisting densely, I'm only quoting the API an tutorial, so please read them attentively.
    Edited by: jduprez on Nov 2, 2009 2:29 PM - Sorry Kevin, hadn't seen you latest reply. I completely subscribe to the thought process you recommend.
    Edited by: jduprez on Nov 2, 2009 2:32 PM
    Thinking about it further, I don't completely subscribe... Indeed it looks like a bad idea to make the OP wonder about dialog.setVisible() when JOptionPane enables him to forget about the hand-made dialog. I stand by my own advice ("JDialog" should not even appear in this code extract).

  • Creating Web service for PL/SQL Procedure with Complex Data Types

    I need to created web service for PL/SQL Procedure with Complex Data types like table of records as parameters, how do we map the pl/sql table type parameters with web service, how to go about these?

    Hello,
    When you are creating a service from a Stored Procedure, the OracleAS WS tools will create necessary Java and PL wrapper code to handle the complex types (table of record) properly and make them compatible with XML format for SOAP messages.
    So what you should do is to use JDeveloper or WSA command line, to create a service from your store procedure and you will see that most of the work will be done for you.
    You can find more information in the:
    - Developing Web Services that Expose Database Resources
    chapter of the Web Service Developer's guide.

  • XI for create web servicies for SAP R/3 4.6C

    Hi All,
    we are implementing PM (Plant Management) module of SAP R/3 4.6C and we have the necessity to create web services for some PM functionalities. Infact we need to integrate our SAP R/3 4.6C with other applications (non-SAP) through TIBCO (it's mandatory). So we think to use SAP XI. Moreover our users don't want to use SAP GUI for the accessing to the PM functionalities but they want an UI more friendly. So we think to use SAP EP.
    Which is your opinion about this architectural scenario? Is it possible to fulfil the requirement of our business users with a more simple architectural solution (for example with WEB DYNPRO)?
    Many thanks in advance for your collaboration.
    Regards,
    Bob

    Infact we need to integrate our SAP R/3 4.6C with other applications (non-SAP) through TIBCO (it's mandatory). So we think to use SAP XI.
    TIBCO is another middleware. So once you expose your R/3 functionalities as web service, you may directly use TIBCO to integrate and XI won't be required at all.
    Moreover our users don't want to use SAP GUI for the accessing to the PM functionalities but they want an UI more friendly.
    WebDynpro application would provide you an easy GUI and could act as Soap client as well to send data.

  • How to use Web Serivce for not jsr 172 phone

    Hi:
    Is anyone know, how to use web service for phones that only have standard J2ME package installed (without jsr 172 web service packagenstalled)?
    thank you

    Hi,
    I think you need to write the code for this from scratch (built on top of existing HTTP functionality). There may be open-source J2ME code you could use. I've never tried this so I'm afraid I don't know any more. But maybe that is what you were asking... i.e. does anyone have code that does this already...
