Creating A Web Service from a Function Module in ERP2004

I have searched for documentation on this without success.
I would be grateful if anyone could point me in the direction of any documentation on this subject, how to do it and what infrastructure needs to be in place for it to work.
Many Thanks
David

WAS640 makes the creation and consumption of web services very easy. Here is a help document to give you a step-by-step of how to create a web service in ABAP.

  • Error while generating Web Service from a function module.

    Hi Experts,
    I am trying to create a web service from function module by doing the steps as mentioned in the below document:
    http://www.sdn.sap.com/irj/scn/index;jsessionid=(J2EE3417800)ID1146834250DB10778842957931285337End?rid=/library/uuid/80fa3dff-ce76-2a10-3f94-f3df8f2db5a2&overridelayout=true
    When i save it as an local object instead of generating the Web Service it gives me the below error:
    "Error during activation of Web Service"
    Kindly let me know what needs to be done inorder to resolve this issue.
    I have a feeling that this error may be with respect to some authorizations, in that case how do we resolve it
    Helpful Inputs Awaited.!!!

    Hi Dhawani,
    Hi Pavan,
    Can you please elaborate...how this will help??
    Thanks

    I dont know the specific reason but internally there may some inconsistancy but i faced the same error and i tried with saving it in the package.
    Thanks

  • Web Service from RFC function module

    Hi all,
    I'm searching for a way to create web services from RFC-enabled function modules. I know there is a wizard, but it's not suitable for my problem:
    I have around 30 function modules (number raising in near future) I want to enable for web services, most of them share the same structures representing the underlying data model. When one structure is modified (i.e. a new sub-structure is added) I have to recreate all web services, which is quite uncomfortable.
    In addition, using the wizard results in one wsdl-file for each web service operation, that leads to an administration overhead using this web services from a java frontend.
    So I'm searching for a "bulk creation". I also know the wizard can be used for a function group, but I can't put all my RFC-enabled function module in one function group, that would lead to confusion in the package.
    Does anyone know how web services are created programmaticaly? If I had a function module which creates the web services I could write a function module which creates all web services I need.
    Thank you in anticipation!
    Florian

    I'm not sure I understand the 're-create' part...how are you re-creating the web service?  if you modify the interface of a function-based web service, then you use the 'modify operations' functionality (context menu - right-click) to regenerate the web service interface; this works for a function group based web service as well and hits all of the methods at once.  As for the java overhead on function group services, stating the obvious, maybe you just need to lower the number of functions in your groups.  We use .Net-developed applications with multi-function webservices and don't have any overhead issues.

  • Web Services  from ABAP function modules return values- leading zeros

    I am using several web services from SAP CRM (5.0) that were created from Function modules ( I am assuming that that they are in ABAP).
    I can call the web services fine and they work as expected, but I am seeing a lot of leading zeros in the return values of fields in tables from the Web service.
    The ABAP er’s are telling me that they cannot see the leading zero’s.
    So my question is where these are appended to the values in the whole process. When I execute the Function Module in SAP CRM from transaction SE37 I can see the leading zeros. So I think that this is something that has to be handled by the ABAP er’s and not in the client consuming the web service.
    Are the functions in SAP CRM that can remove leading zeros for fields in a table (that is an export parameter?)
    Jawahar

    Hello Jawahar
    If you run your (RFC-enabled) function modules using the SAP-GUI (i.e. in dialog) then the GUI automatically replaces leading zero when the function module returns any data. However, calling the same function module remotely you will always see these leading zeros.
    These so-called conversion exits are defined as attribute of domains in the ABAP dictionary. If the function module used for the WebService is a standard fm then you have little chances to get rid of the leading zero. Perhaps the WebService has some attribute to suppress conversion exits or activate them when retrieving the data.

  • Test web service for a function module

    Hello,
    I have created web service for a functiona module. I can see the same service in SE80 in Enterprise Services.

    Thanks Venu for your input.
    Unfortunetly we do not have Java stack on our development system. You said we can test it by SOAP UI tool. Where do I see the WSDL file for the service?
    I used WSDL from SE80 --> Service --> WSDL tab, but SOAP UI does not accept this format ?
    What are the other ways I can test this web service? I think about SAP PI, importing RFC & creating web service or creating ABAP proxies... Which is the best way to go forward in case you do not have Java stck.

  • Parse errors while creating a Web service from Java class!

    Can anybody tell me please, is it possible to create a Web Service from java class where the input from user is required ?
    I have the following program, which is successfully compiled, but when I'm trying to make a web service in JDeveloper, the following error occurs:
    "Validation failed.
    The implementation class primePackage.isPrime ofport type MyWebService contains parse errors."
    import java.io.*;
    import java.util.*;
    class isPrime
    public static void main (String args[])
    Scanner reader = new Scanner(System.in);
    int n;
    System.out.println ("Enter a number you want to know is it prime or not");
    n=reader.nextInt();
    if (isPrime(n))
    System.out.println ("True");
    else
    System.out.println ("False");

    Hi,
    Can anybody tell me please, is it possible to create
    a Web Service from java class where the input from
    user is required ?Yes, the parameters of your method will be mapped in WSDL.
    But i've some considerations about your code.
    I suggest you change the name of isPrime do Prime, its a good code convention to put the name of class starting with Upper case. and isn't good the name of class equals to name of method.
    I suggest you to change the "static boolean isPrime (int n)" to "public boolean isPrime(int n)" to publish a method as a WebService method it's must be public and not static. After this change try to generate your Web Service.
    Regards.

  • Any difference in creating a web service from a java class or session bean?

    Hi,
    The JDeveloper tutorial at http://www.oracle.com/technology/obe/obe1013jdev/10131/devdepandmanagingws/devdepandmanagingws.htm demonstrates creating a web service from a plain java class. I'm wondering:
    - Is it possible to create a web service from a stateless session bean instead of a java class? If so, what's the proper way to do this in JDeveloper? When I tried doing so in JDeveloper 10.1.3.0.4 (SU5) using the J2EE Web Service wizard, the wizard did not list the session bean in the Component To Publish dropdown (it does list any java classes available in the project). I can proceed by manually typing in the name of the session bean. After the wizard completes though, the @Stateless annotation that had been in my session bean class code is removed and replaced by a @WebService annotation. The end result is that it looks like it made no difference whether I had tried to create the web service from a session bean or plain java class as the annotations in the resulting web service code are the same (although if I had started from a session bean, the class for the web service still implements the Local/Remote EJB interface that the session bean originally implemented).
    - Assuming it's possible to create a web service from a stateless session bean, is there any advantage/disadvantage creating a web service from a java class vs a stateless session bean? I'm creating the web service from scratch so I also need to either build the java class or stateless session bean the web service would be based on from scratch too.
    Thanks for any ideas about this.

    Hi,
    EJB Session beans (EJB 3.0) are deployed as WebServices by annotating the class with @WebService and the methds with @WebMethod (both tags require you to add the JSR-181 library to your project (available in the JDeveloper list of libraries)). Unlike the J2E WebService, the EJB session bean service is turned into a WebService upon deployment. This means you obtain teh WSDL file after deployment
    - Assuming it's possible to create a web service from a stateless session bean, is there any advantage/disadvantage creating a web service from a java class vs a stateless session bean?
    The difference is that EJB Session bean based web services are integrated with the J2EE container, which means that they can leverage container services like transaction handling, data sources, security, JMS etc.

    Guys,
    You are asking about an issue that was a pain in the nick for me few months ago. The problem is that you won't find mych help here as I figured out that Apex geeks here either did not do much webservices or ended up hating it as i do :) . This is an error that can be due many different reason, let me ask you this:
    1- Does your the other system you are trying to call through webservices using HTTPS ?
    2- If yes, did you create a valid oracle wallet for that https connection ?
    3- Make sure you are using the correct URL ( am sure you do, just double check )
    4- If using a proxy, then you have to define that in the web service reference creation page
    provide more info and I hope I can help you with this,
    Sam
    Please reward good answers by marking them correct or helpful!

  • SAP Cloud Application Studio Create Custom Web Service From Custom Business Object and Consume in External System

    businessobject Custom_Integration {
      element EP_VAL1 : LANGUAGEINDEPENDENT_MEDIUM_Text;
      element EP_VAL2 : LANGUAGEINDEPENDENT_MEDIUM_Text;
      element IP_RES : LANGUAGEINDEPENDENT_MEDIUM_Text;
    I have created the Web Service using this custom business object.
    3) How i can use this web service in external system? what are the prerequisite steps in external system to consume this service in it?
    Please anyone have idea about this how to do this and how to achieve this using SDK and custom business object.
    Many Thanks
    Mithun

    Hello Mithun,
    Does this section in the documentation help you:
    SAP Cloud Applications Studio Help -> Developers Desktop -> Web Services
    The entry "Task -> Create a Web Service" describes how to create a Web Service on your own BO
    The entry "Task -> Test a Web Service" helps you how you can use it in a foreign tool / application.

  • How can I create a web Service from my Web Dynpro Application ?

    Hi,
    Kindly let me know How I could create a "Web Service" with my Web Dynpro DC project.
    Awaiting your responses.
    Regards,
    Mahesh

    Hi Mahesh,
          You can use the web services by creating the Model in web Dynpro
    And if you want to publish your own web service then you have to create a EJB module and publish as a web service.
    Thanks

  • Creating a Web Service From an existing Java Project

    Hi folks,
    I'm new to web services and SAP Netweaver so I need to know if I can use my exisiting Java codes (not EJB's though) for creating web services and the WSDL. I've already gotten the codes working and all and just need to make them into web services and deploy them (plus give my WSDL).
    I've noticed in some samples that they used EJB's for creating new web services and I've been trying to find samples/steps on just creating webservices from exisitng java codes. I've been using AXIS but I've been told that creating web services using the Netweaver Developer Studio is rather easy.
    Thanks in advance!

    Hi Amol!
    Thanks for the link
    I was trying it out, but could you see if this was correct:
    I just made one simple java project (with one class file) and using the link you sent me and did just the step for using the web service Creation Wizard. I made it say Test service and got into the Web Services Explorer but it says it couldn't open my wsdl:
    IWAB0379E Unable to open http://localhost:50000/HelloBeanService/HelloBean?wsdl.
    IWAB0135E An unexpected error has occurred.
    WSDLException
    WSDLException: faultCode=OTHER_ERROR: http://localhost:50000/HelloBeanService/HelloBean?wsdl
    Did I miss a step?
    Thanks again!

  • Can we create a Web Service from a Business Object??

    Hello All,
    Has anyone created a Web Service using a Business Object?
    When I am trying to create a Web Service in TM box, I can see that couple of options like Business Objects, Process Agents are disabled and rest like Consumer Group, Service Provider are enabled. Any idea why this is happening. Is this related to some configuration setting.
    Regards,
    Abhishek

    please elaborate in which environment or case you are creating Web Service from Business Object.As per my understanding we generally create web service through Wizard.
    Thanks

  • Assemble Web Services from database functions and procedures?

    Web Service Assembler can assemble Web services from PL/SQL packages.
    Can it be used to assemble Web services directly from functions or procedures?
    Thanks,
    Jim

    Hi,
    No, it relies on a package and takes each of the publishable functions and procedures as the web serivce methods.
    Have you also tried using JDeveloper? It uses WSA under the covers but gives you a great GUI for selecting and working with your code
