  • [Best practice] How to call a service from custom Java code

    Hi all,
    I'm wondering what the best method is to call a standard service from custom Java code?
    In a specific situation iDoc script is extended with custom functions with a custom component. There's Java code mapping to these functions that is executing these functions. The iDoc script functions are called from a workflow entry script.
    In the Java code that runs when the custom iDoc functions are called, I want to call a standard Content Server service. I don't think that the m_service variable is available, so filling the binder and using m_service.executeService() probably isn't possible.
    Also, if it were possible (that is, if I want to call a standard service from my own custom service Java code), what would then be the best method to do so?
    Regards, Stijn

    Hi Sapan,
    Let me explain a bit further.
    I'm an UCM consultant trying to solve a problem that occured at a client when they installed the CS10gR35CoreUpdateBundle.
    Content items are entered into a Workflow when they are checked in. Part of one of the entry scripts of the a workflow step is that related content to the content item in the workflow is (re)submitted for conversion.
    To achive this, a custom component provides an iDoc script extension. This iDoc function (resubmitForConversion) is implemented in Java (the class extends ScriptExtensionsAdaptor).
    In this Java method, first the related content items are fetched. Then the service RESUBMIT_FOR_CONVERSION should be called for all dID's in of the related content.
    Thus, at a certain point in the custom Java code, a native Content Server service must be called. Of course the class of this Java code does not extend the Service class, so the m_service object isn't available.
    The thing is: before installed the 10gR35CoreUpdateBundle everything worked OK. This code was used to execute the service:
            Workspace workspace = CommonUtils.getSystemWorkspace();
            String cmd = binder.getLocal("IdcService");
            if (cmd == null) throw new DataException("!csIdcServiceMissing");
            ServiceData serviceData = ServiceManager.getFullService(cmd);
            if (serviceData == null) throw new DataException(LocaleUtils.encodeMessage("!csNoServiceDefined", null, cmd));
            Service service = ServiceManager.createService(serviceData.m_classID, workspace, null, binder, serviceData);
            UserData fullUserData = CommonUtils.getFullUserData(userName, service);
            service.setUserData(fullUserData);
            binder.m_environment.put("REMOTE_USER", userName);
            ServiceException error = null;
            try {
                service.setSendFlags(true, true);
                service.initDelegatedObjects();
                service.globalSecurityCheck();
                service.preActions();
                service.doActions();
                service.postActions();
                service.updateSubjectInformation(true);
                service.updateTopicInformation(binder);
            } catch (ServiceException e) {
                error = e;
            } finally {
                service.cleanUp(true);
                if (!CommonUtils.isWorkspaceConnectionInTransaction(workspace)) {
                     workspace.releaseConnection();
            }the first problem was that the CS began to complain that a transaction was started within another transaction. So I suspect that the 10gR35 update wrapped a transaction around a workflow script entry.
    With some decompiling I figured out how a service is called from iDoc with the <$executeService()$> command. So I replaced the code above with:
                  String cmd = binder.getLocal("IdcService");
                ServiceData serviceData = ServiceManager.getFullService(cmd);
                if (serviceData == null) throw new DataException(LocaleUtils.encodeMessage("!csNoServiceDefined", null, cmd));
                Workspace workspace = CommonUtils.getSystemWorkspace();
                Service service = ServiceManager.createService(serviceData.m_classID, workspace, null, binder, serviceData);
                UserData fullUserData = CommonUtils.getFullUserData(userName, service);
                service.setUserData(fullUserData);
                binder.m_environment.put("REMOTE_USER", userName);
                service.initDelegatedObjects();
                service.executeSafeServiceInNewContext(cmd, true);This solved the transaction problem but introduces another problem: !csUnableToResubmitItem,(null)!csIllegalScriptAccess,RESUBMIT_FOR_CONVERSION
    The Service Reference Guide says that the access level for RESUBMIT_FOR_CONVERION is 33 (Read, Scriptable). However, in shared/config/resources/std_services.htm the access level is specified as 2 (write).
    Thus, my question still is:
    What is the best method to call a standard Content Server service from any Java code (so without extending the Service class, or having the m_service object available)?

  • Has anybody created Iview from "Webdynpro Java" component in CE7.1 ?

    Hi All,
           Has anyone created Iview from Webdynpro Java component in CE7.1.
    Because the wizard that appears for creation of Iview has only "Webdynpro ABAP"
    component.There is no option to create iview from "Webdynpro Java" component.
               Althought in portal content--->Template folder i can see there is also
    another template for "SAP Webdynpro iview" which i think is for the Java scenario.
    But issue is, its not coming in the wizard.Can anyone tell me how to make it appear in the wizard ? It will be of great help to me.
    Thanks and Regards
    Ashis

    Hi Ashis,
    your deployed webdynpros are published under "web dynpro applications". just copy the webdynpro from there and paste it into the portal content section.
    http://help.sap.com/saphelp_nwce10/helpdata/en/ce/e0d6f54ae641fc9566501cffaa8c6c/frameset.htm

  • How to call a webService from WebDynPro ABAP ?

    We are trying to call a webService from WebDynPro-ABAP application. It is not working, While if we are calling the WebService from a Report, it is working.
    How exactly do we call a WebService from a WebDynPro-ABAP application?
    What are the main steps involved ?

    Hi Phani,
    You will need to create a service call as follows.
    Right click on your WD component name and select Create->Service Call
    The wizard will guide you through a series of steps to make a Web Service Call. On the 3rd screen, it will give you options such as Function Module, Web Service, etc
    Before making a service call, you will need to create a proxy for the Web service in the ABAP Workbench using a WSDL document as a basis. To create or consume Web services, you will need the authorizations associated with the role SAP_BC_WEBSERVICE_ADMIN.
