Developing a web dynpro application compatible to two JCO destinations

I have created a web dynpro application and integrated into a portal, which access R/3 using a JCo destination and retieves the data using a BAPI.
But I want to integrate the same application into another portal, which would access the different R/3 system having the same function module.
Is there any way for switching between two Jco destinations as the same application could be made to work for both the systems.
please suggest me as I am stuck up with this issue.
Thanks and regards
kris

hi Radha Krishna
Thanks for your reply,
Currently I have three iviews for the complete application Can you please tell me where to do the settings:
In the application properties dothe following:
Use the following url parameter to the
application URI sap-wd-arfc-useSys=<DEFAULT_SYSTEM>:<SUFFIX_OF_MAPPED_SYSTEM>
In the default system you can change your JCo destination name.
where do I do all these settings.
Kindly let me know.
Thanks and regards
kris

    Hi Neha,
    It seems that there is problem with your SDM server. It seems that during J2EE engine configuration SDM server is not configured. Actually this configuration is done by Basis Team.
    By the way try out your Server setting:
    Go To:: Windows -> Preferences -> SAP J2EE Engine
    [Mention the required details over there]
    And Check whether you are getting Active SDM Server under J2EE Engine.

    thanks in advance

    Hi,
    Do you want to change the message server name thriugh coding then use the below code.
    Store the message server name in a customizing table.
    use the below code to replace the MS name:
    DATA    lv_temp_str TYPE char255.
      DATA    lv_split1 TYPE char255.
      DATA    lv_split2 TYPE char255.
    DATA :  lv_string TYPE string,
              lv_application TYPE string.
    DATA    lv_dns_str TYPE /mrss/t_rm_dns_str.
    CALL METHOD cl_wd_utilities=>construct_wd_url
        EXPORTING
          application_name = lv_application " webdynpro application name
        IMPORTING
          out_absolute_url = lv_string."url of the application.
    lv_dns_str = message server name form the customizing table
    lv_temp_str = lv_string.
      SPLIT lv_temp_str AT '//' INTO lv_split1 lv_split2.
      CLEAR lv_split1.
      lv_temp_str = lv_split2.
      SPLIT lv_temp_str AT '.' INTO lv_split1 lv_split2.
      lv_temp_str = lv_split1.
      REPLACE lv_temp_str IN lv_string WITH lv_dns_str.

  • Web dynpro application using workflow

    Hi all,
    I have developed a web dynpro application and attached that to the portal, so the user will login into the portal and will access the application. We have a new requirement now, when a user enters the data and hit save button on the web dynpro application, the workflow should trigger and should send the filled out (everything filled in) web dynpro application to his superior, the supervisor should be able to click on a link (which he should get through workflow) and should get the web dynpro application filled in. I am not sure how can I do this, so can you please guide me through.
    Thanks,
    Raj

    Hi Raj,
    could I suggest perhaps that you have a good search of SCN - there have been multiple posts about this sort of thing in the past.
    for example : the wiki article
    [Integrating WebDynpro ABAP applications with UWL for workflow in Portal|http://wiki.sdn.sap.com/wiki/display/WDABAP/IntegratingWebDynproABAPapplicationswithUWLforworkflowin+Portal]
    is it perhaps that you do not use the UWL at your site? Or do you want to to send an email to the manager with a link directly to the approval application? The last case is one that I've come across many times before - it just means that you'll need to generate an approval task that is ended by a wf event and send an email to the manager with a URL parameter in the launch of the WDA application so that the app can pick up the details required to display and raise the WF event to complete the approval wf task.
    There are all sorts of ways of persisting the information in the form so that the manager can see it in the approval. You can use the workflow container, you can use a db table, you could even use a shared memory area (not that I'd recommend this for this usage). But this is more a case of how to persist information in a workflow and probably a better question (search first, it's probably been answered already) for the WF forum and not the WDA forum.
    Good luck in designing and building your application. Perhaps when you are done you could write a blog about your experience and further share how to do this with others.
    Cheers,
    Chris

  • Web Dynpro Application URL Host Name Not Correct

    Hello,
    I am developing a web dynpro application in our development system but when I activate the application it gets a URL that points to our test system.  When I test the application in HTTP Service (SICF) the URL for the development system is passed to the browser.  WHere do you maintain the host that is being used to build the URL for the web dynpro application when it is activated.
    Thanks,
    Jim N.

    Hello,
    To configure the FQDN (host name full), please take a look at these:

  • Web dynpro application using java

    Hi Experts,
    I am new to netweaver . I developed one web dynpro application in  NWDI  but input fields are disabled on screen .
    please suggest reason why it is happend.
    Thanks,
    Santosh.

    Hi Santosh,
    Once you create the input fields in NWDS you need to bind input field with context attribute to enable in the display screen.
    Refer to this Re: Calendar UI element in NWDS and also refer to Tutorials & Samples for Web Dynpro Java [original link is broken]
    Hope it helps

  • Navigationservice.getInitialNodes in Web Dynpro Application

    Hi,
    I am trying to develop a Web Dynpro application which will return the NavigationNode of a logged in user.
    I created a navigationService object as shown below
    INavigationService navigationservice =
              (INavigationService) PortalRuntime.getRuntimeResources().getService(
                       INavigationService.KEY);
    I created a HashTable object with
    environment.put("User", anIUser.getUniqueName());
    environment.put("NavigationPrincipal", anIUser.getUniqueID());
    After this, when i try to get the initial nodes,
    navigationservice.getInitialNodes(environment)
    i am getting the following the error
    com.sapportals.portal.navigation.NavigationService.getInitialNodes(NavigationService.java:1726)
    com.sapportals.portal.navigation.NavigationService.getInitialNodes(NavigationService.java:358)
    com.sapportals.portal.navigation.cache.CachedNavigationService.getInitialNodes(CachedNavigationService.java:137)
    What would be the problem here?

    When putting getSAPUser inside the hashmap, it works.
    environment.put("NavigationPrincipal", clientUser.getSAPUser());

  • Navigation Error in Web Dynpro Application

    Hi All,
    I developed a web dynpro application with 2 views.
    I implemented the navigation paths(in and outbound plugs). I have a Next button in the first view and when
    I clicked the next button it opened the second view.
    It was working fine until, i created custom controller
    and defined model node and model binding by calling RFC.
    In the first view, i created a model node corresponding to the custom controller model  node and defined the context mapping between the first view and the custom controller.
    When I run the application (the first view displays data calling RFC) once I clicked the next button i got this error message.

    Hi

    I think you haven't done that.

    Hi ,
    Mobile WebDynpro
    The SAP Web Application Server allows direct online access to Web Dynpro applications using mobile devices. As part of the SAP Web Application Server, Web Dynpro provides a development and runtime environment with which you can quickly and simply create professional user interfaces for desktop PCs or for mobile devices. An appropriate infrastructure and renderer classes are provided for developing mobile Web Dynpro applications for Pocket PCs as well as for BlackBerry Wireless Handhelds and Nokia Series 80 devices.

    WebDynpro Java
    Web Dynpro is a client-independent programming model of the SAP NetWeaver technology platform for developing user interfaces for professional business applications. It is based on the model view controller paradim which ensures that the business logic is separated from the presentation logic. This architecture is visible in the Web Dynpro perspective of the SAP NetWeaver Developer Studio (NWDS).
    Web Dynpro helps you with the development of Web applications by:
    ·        Ensuring platform-independence with the meta model approach
    ·        Minimizing the implementation effort through declarative programming
    ·        Supporting a structured design process by applying the model view controller paradigm
    ·        Providing reuse and better maintainability by using components
    ·        Providing graphical support with tools in the Web Dynpro perspective
    ·        Providing the SAP NetWeaver Java Development Infrastructure (NWDI) which supports team work with different services such as source code versioning and the Central Build Service.

  • Securing Web-Dynpro application with Netegrity

    Hi,
    I'm developing a web-dynpro application that will be secured by Netegrity SiteMinder. SiteMinder is a reverse-proxy that authenticates the user and adds the user details as additional headers to the HTTP stream. According to the documentation I found in SDN with regards to JAAS and NetWeaver it looks like SAP has added callbacks so that I can retrieve HTTP headers in my custom login-module. I've implemented a simple login-module and deployed it, but now am stuck with the following issues:
    (1) I can't seem to be able to debug the module (even when I create a simple HelloWorld.jsp and require the use of this module in the visual administrator, the debugger seems to ignore the break-points).
    (2) I can't find any possibility to configure the engine so that this specific module is required for authenticating my deployed web-dynpro application.
    My questions are as follows:
    (1) Is it possible to use standard JAAS authentication with web-dynpro applications?
    (2) How do I debug JAAS login modules?
    Regards, Chris.

    <b><b>Hi Adrian
    During the Life cycle of your application Your connection will be Released when it is inactive for particular Time (The inactive time limit will be specified in the JCo Pool Settings that would be in milli seconds)

  • Error - Creating a Web Dynpro Application Accessing ABAP Functions

    Dear All,
    we are trying to implement a web dynpro application with accessing ABAP functions.
    Previous tasks:
    -     insert the ABAP system into the SLD from the NWDI System (Transaction RZ70; the ABAP system is correctly insert into the SLD => technical systems)
    -     equipped the JCO connections with the web dynpro content manager (ping and test = OK)
    It’s the standard tutorial out of the SDN called “Creating a Web Dynpro Application Accessing ABAP Functions”.

    -     I’m able to start the application out of the Web Dynpro content manager with “run” => only the user interface is displayed without any functionality
    -     The “normal” start over the NWDS fails => error text
    “com.sap.tc.webdynpro.services.sal.core.DispatcherException: The requested deployable object 'local/J08_Flugdat_Daventdcflight~xxx.com' and application 'FlightListApp' are not deployed on the server. Please check the used URL for typos.”
    There two different URLs in use.
    Start via NWDS:
    http://frasapp562:50000/webdynpro/dispatcher/J08_Flugdat_Daventdcflight~xxx.com/FlightListApp
    Start via web dynpro content manager:
    http://frasapp562:50000/webdynpro/dispatcher/xxx.com/aventdc~flight/FlightListApp
    For test purposes, we started the BAPI (BAPI_Flight_Getlist) on the ABAP system directly. It works.
    Any ideas about the system behaviours (different URLs and missing functionality)?
    Thanks a lot in advanced!
    Best regards
    Christoph

    The Error has been solved – The implementation of a method was missing....
    Thx

    Hello!
    I'm a rookie in the field of SAP Netweaver and I'm justing getting started with some tutorials. My problems with "Creating an Extended Web Dynpro Application" are to massive to be posted on this forum in this stage. What I want to have some help with is to find the source code for that tutorial so I can get som guidence from there.
    Following text is cut out of this page:
    http://help.sap.com/saphelp_nw70/helpdata/EN/5d/f42fef2eec724597a03b6bcc670c2c/frameset.htm
    Creating an Extended Web Dynpro Application
    You can download the Web Dynpro project for the current tutorial from the Software Developer Network SDN (http://sdn.sap.com -> Web Application Server -> Web Dynpro -> Sample Applications and Tutorials) in two versions: one skeleton version you can use for exercises and one final version (solution) for an immediate build, deployment and run on the Java engine of the SAP Web Application Server.
    How hard I try I can't find the specific source code on sdn.sap.com
    Does anyone have a clue where it is?
    Thanks!

    Hi!
    I did what you said but I seem to miss the IDE folder. This is what it looks in my Explorer
    C: > Program Files > SAP > IDE > CE > eclipse > (no folder called "examples")
    I also did a search in this eclipse folder for "examples" but I did'nt find the example I'm looking for
    I am running a newer version of NWDS:
    SAP NetWeaver Developer Studio
    SAP NetWeaver 7.1 Composition Environment SP03 PAT0000
    Maybe that's why things don't look the same?
