ERP2004: ESS JCO session handling in Web Dynpro apps?

Hello,
we run ESS/MSS Web Dynpro scenarios, running on WAS 6.40, SP12 in
Enterprise Portal EP6 SP2 Patch 32. Our go live will be with > 1000 ESS users.
1. When will the sessions in R/3 backend system be terminated by the
Web Dynpro Application?
How is the session handling in FPM (Floor Plan Manager) implemented?
2. Are there any recommendations regarding the JCO connection settings
in Web Dynpro Content Administrator (Maximum Pool Size, Maximum Connections,
Connection Timeout, Maximum Wait Time) to reduce / optimize the load for the
backend system? I found a documentation in SDN but it is not
specific for ESS / MSS based on Web Dynpro.
Background of questions above: The customer is worry about the load on
SAP R/3 backend side: too much current users in the R/3 backend system,
possibly bad performance etc. because the JCO sessions are open a long time.
Are there any experiences with customers running productive ESS / MSS scenarios
based on Web Dynpro?
Thanks & Best regards,
Daniel

Hi,
1. For best practices on JCO settings follow the tutorial below and do it accordingly for your no of users. YOu might have to do some trial and error procedure.
https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/3103eb90-0201-0010-71af-be6f4a6f61d1
2. For standards, security settings, cache management etc, SAP will give a TODO list after a remote audit of your project.

  • Strange JCO error when running Web Dynpro App

    I am developing a new WebDynpro application to be deployed on our SAP
    Portal interfacing with a SAP R/3 backend. The application uses
    multiple JCo destinations (two for each model) all of which were
    configured according the SAP guides (userid/password for metadata and
    ticket for model data). The tests work fine for all connections.
    However, we get HTTP 500 errors when executing the application. The
    main message is : "com.sap.mw.jco.JCO$Exception: (101)
    RFC_ERROR_PROGRAM: 'password' missing".
    I have not been able to find anything to help and SAP themselves have yet to provide us an explanation.
    - I was able to run the application fine in dev and it worked with this error occasionally appeared but now it always appears.
    - Our portal is 2004s SP 10
    - All of the JCOs are configured properly as per SAP instructions
         - modeldata use SSO with user configured in R/3
         - metadata use userid/password
    - Another prototype Web Dynpro application has the same error.
    - All of the Web Dynpro models are Adaptave RFC.
    Any ideas would be greatly appreciated.

    Here is the full exception I am getting.

  • Create a entity using a session bean in web dynpro

    Hi.
    I want to create an entity bean object trough an EJB session bean in web dynpro, e.g using a form in a WD application filled in by a user.
    I understand how to display a list of entity beans through a session bean and a table, but I don't understand how to create (or edit or remove) such information.
    My session beans look like this:
    @Stateless
    public class MyObjectBean implements MyObjectLocal {
         @PersistenceContext(name = "MyObject", unitName="ProjectPU")
         public EntityManager em;
         public void create(MyObject myObject) {
              em.persist(myObject);
         public void edit(MyObject myObject) {
              em.merge(myObject);
         public void remove(MyObject myObject) {
              em.remove(em.merge(myObject));
         public MyObject find(Integer id) {
              return em.find(MyObject.class, id);
         @SuppressWarnings("unchecked")
         public List<MyObject> findAll() {
              return em.createNamedQuery("MyObject.findAll").getResultList();
    So the model class would be called Request_MyObjectLocal_create.
    I attempted to use [this|http://help.sap.com/saphelp_nwce10/helpdata/en/45/dd45e4bc295595e10000000a1553f7/frameset.htm] help file but I find the answer (step 17) quite unclear.
    Help is greatly appreciated!
    Vincent.

    I've just found the solution from Steve Muench weblog, always useful by the way!
    You can find the solution at this link http://radio.weblogs.com/0118231/stories/2004/05/07/handcodingDynamicDiscoveryOfEjbdeployedAppmodule.html
    In summary, we need to use the class com.evermind.server.rmi.RMIInitialContextFactory, which supports dynamic lookup, and implement the lookup ourselves.
    The code I've written to lookup the service is listed below:
    public static ApplicationModule getAppModuleManutencao() {
    try {
    Context ctx = getContext();
    ManutencaoFacadeHome home = (ManutencaoFacadeHome) ctx.lookup(EJB_MANUTENCAO_BEAN_NAME);
    ApplicationModule am = ApplicationModuleProxy.create(home, null);
    return am;
    } catch (NamingException nex) {     
    nex.printStackTrace();
    return null;
    private static InitialContext getContext() {   
    try {     
    Hashtable env = new Hashtable();
    env.put(Context.INITIAL_CONTEXT_FACTORY, "com.evermind.server.rmi.RMIInitialContextFactory");
    env.put(Context.SECURITY_PRINCIPAL, "admin");
    env.put(Context.SECURITY_CREDENTIALS, "welcome");
    env.put(Context.PROVIDER_URL, "opmn:ormi://dsv008:OC4J_dvt20/mct");
    env.put(Context.SECURITY_AUTHENTICATION, "simple");
    return new InitialContext(env);
    }catch (NamingException e) {     
    e.printStackTrace();
    return null;
    I hope this helps someone!!!

  • Call WAPI error in web dynpro app

    I write a very simple demo workflow, there is a approve step that call a web dynpro app.
    I pass workitemid to my web dynpro program, then It call fm SAP_WAPI_RESERVE_WORKITEM and SAP_WAPI_WORKITEM_COMPLETE to comlete workitem programmly.
    In SAPGUI workplace ,I receive a message ,then I execute workitem,web dynpro UI page is showed.When I execute approve operation(call two wapi fm above in approve event handler),SAP_WAPI_RESERVE_WORKITEM and SAP_WAPI_WORKITEM_COMPLETE's export parameter "return_code" is 1.
    But I test/execute my web dynpro program standalone in workbench,all is ok,demo workflow continue.
    I have spent a plenty of time for it,help me!
    I'm sorry for my poor english .

    Thanks for your advice. I am a new one for SAP development.
    According to your advice, I use SAP_WAPI_DECISION_COMPLETE instead of SAP_WAPI_RESERVE_WORKITEM and SAP_WAPI_WORKITEM_COMPLETE, I get the same result.
    test web dynpro application standalone, it's ok;in SAP workplace ,SAP_WAPI_DECISION_COMPLETE  method's exporting parameter "return_code" is 1.
    My code is following :
    CALL FUNCTION 'SAP_WAPI_DECISION_COMPLETE'
      EXPORTING
        WORKITEM_ID          = l_wi_id
        LANGUAGE             = SY-LANGU

  • How to change the web page title of a web dynpro app?

    Hello,
    I would like to change the HTML page title of a web dynpro application without renaming the application component itself - but how?
    Thanks for your comments!

    Hi M Walter,
    Assuming you are using Web Dynpro Java, you can change the title of the Web Page for Web Dynpro App by adding the title to the main window of your app.
    Go to Windows and open the properties. There will be a field called 'title'. Give the title you want, save, build, DC->Build and deploy.
    The title you gave to this Window will be displayed as the title of your Web page.

    Hi Siddarth,
    If you want provide the interaction between two Web Dynpro applications then you must develop those projects as Development Components as DCs provides the reusability of the components created.

  • How do I undeploy/delete Web Dynpro App

    Hi,
    I created a Web Dynpro App in NWDS for some testing. Now I want to delete this App from Server but I cannot find any button saying undeploy or delete.
    Can anyone tell me how I can delete a deployed Web Dynpro App?
    Cheers
    Christian

    Hi Christian,
    You definitely should! Keep in mind that the entries are NOT sorted alphabetically, so you have to go through the complete list!
    You also can try to remove it via VA, there via "Services" -- "Deploy" -- choose your app -- "Remove". I'm not sure if this really removes everything from the server. You may give it a try, but as said, removing it via SDM is the most original way.
    Hope it helps

  • How to close portal page by Web Dynpro App

    Hi There,
    I would like to close a portal page by clicking a button of a Web Dynpro App which is inside an iView on that page.
    Is this possible or not?
    Bertil

    Bertil,
    First, it is very bad decision to make decisions instead of user. Just redirect him to logoff page and let close window himself.
    In WebDynpro you may use <b>Exit plug</b> on interface view with parameter <b>Url</b> (notice the case) of type string.
    Then you may previously fire this plug with JavaScript url: javascript:void(window.top.close())
    In recent versions of WD this will not work. So you have to redirect user via exit plug to some static html page, that contains in header <script>window.top.close();</script>

  • Hi Friends: Do we have ESS and MSS in ABAP web dynpros

    Hi Forum,
    Do we have SAP std. web dynpros on ESS and MSS , do you list out this ABAP web dyn on this..
    Thanks in Advance,
    Srinivas M.

    Hi , Vivek has right, SAP is slowly migrating WDJ/BSP applications to WDA technology.
    In fact, referring to Employee Self-Service, since 1.5, all aplications come in WebDynpro ABAP technology (Note [1450179|https://service.sap.com/sap/support/notes/1450179])
    Referring to Manager Self-Service, the change was more gradually; for example, for Compensations (ECM) since 1.0 some reports already come in WDA, but in MSS 1.4 the Planification app arrives in WDA.
    Most applications for HR Administrator was converted to WDA since 1.2 version (EHP2).
    For a app-to-app check you can go directly to help.sap.com, then enter by business package until app, and look for Technical Data table, Runtime Technology field.
    Best regards!

  • Error handling in Web Dynpro

    Hello,
    in a web dynpro applicatio we are currently developing we have the following scenario for error handling:
    We want to redirect the user to an error page everytime an error occurs. This page should be called whenever an exception is raised in the code (regardless of whether the error happens in the back end or in the front end)
    Is there a way to achieve this with Web Dynpro?
    Regards,
    Jan Aufdemkamp

    Hi Jan,
    You can create a an outbound Plug of type Exit in the Interface View Controller and then add the controller to properties of the controller where you need to do the error handling.
    Also the exit outbound plug should have a parameter of named Url of type string.
    Then fire the plug in the exception handler.
    Hope this helps.
    Regards

  • Ess Time Sheet and Attendance Web Dynpro - ABAP or JAVA

    We are determining the resources we will be needing for the HR - ESS Time Sheet and Attendance Module.   
    What is this module written in.  ABAP Web Dynpro or Java Web Dynpro.
    Many thanks, 
    Multiple replies welcome.

    The ESSTimeSheet is now called Record Working Time & for now it is still in WebDynpro JAVA.. looking at how complex the whole application is, it will really take some beating to rewrite the same in WDA.
