How is a WebDynpro application configured to run

Hi,  how are the web dynprosapplications accessed in the real time.  DO the users use the URL for the WD application or they are embedded in the Portal.
Sorry! if my question doesnt make sense, I just strated learning WDAs.
Thanks!

Hi,

    Hi,
    Please try out this way-
    Have a look at this table -
    WDY_CONF_APPLU - (Customizing Data for Web Dynpro Applications).
    after you are done with the configuration--
    Ge the config id for the given application from this table. And depending on the user get an entry from this table and display accordingly.
    Please refer to these links -
    different default layouts for different CONFIG_IDs
    Get WDCONFIGURATIONID

    The value <b>ctx.lookup("<jdbc_pool>");</b> depends on your system id.
    if your system id is SID the the string has to be <b>jdbc/SAPSIDDB</b>
    you can check it via visual admin >> server >> services >> jdbc con.

  • How to call webdynpro applications from outside

  • How to keep an application level object running with SunIDM?

    We are working on intergrate a gmail project with SunIDM. We need an application level object running with SunIDM so it will maintain a token generated from Gmail side. In anther servlet project, I had this object saved in the attribute of the ServletContext, then other session level servlet could share this attribute anytime. Is there a way to store attribute in Servlet Context and have it shared by different user session in SunIDM? I have been reading documents and searched this forum, haven't find any topics related how to maintain an application level object live. Hopefully that I can get some hint here.
    Thank you so much.

    Paul, Thank you so much for the further explaination. I don't think it will work since the token generated from gmail will expire every 24 hours.
    We are using the gdata library published from by gmail people, and I create a new UserService object and have it run in the application level. The UserService object will generate a token and renew it every 24 hours behind the scene. Here is how I implement it in my Servlet project:
    //to have a UserService object running at the application level:
    public class GmailUserService extends HttpServlet {
    public void init(ServletConfig config) throws ServletException{
    super.init();
    userService = new UserService(myApplication);
    config.getServletContext().setAttribute("gmailUserService", userService);
    //to access this UserService object from other servlet in each user session:
    UserService userService = (UserService)servletContext.getAttribute("gmailUserService");
    Gmail will trigger an error if we create a new UserService object for each user. They recommend to have all the user to share one UserService object. I am looking for similar approach in SunIDM.
    Thank you again, Paul, for trying to help.

    Hi Bala,
             I think there is no possibility as for your query. You will be allowed to create a webservice which is a piece of code that can be applicable to required application. Gothrough the following link to know clear details about webservice.

  • How to immigrate Webdynpro application into EP ?

    Hi all.
    Is there any example to describe how to immigrate one webdynpro application into Enterprise Portal ?
    I need to develop some application in Enterprise Portal. I think I have 2 ways to achieve it.
    1. develop the application in webDynpro, then migrate it into EP.
    2. develop it directly in EP.
    I prefer 1st way, because in this way my maintenance job will becomes easy.

  • How to use WebDynpro Applications in Guided Procedure?

    Hello,
    i want to use a WebDynpro    application as a part of a guided procedure. Therefor i developed a simple WebDynpro    application as described in the NetWeaver    Developer Studio Help. The Application consists of only two views. The first view is to enter data, the second displays them. So far so good....
    In the next step i wanted to integrate this application as a CallableObject for execution in my guided procedures process. The wizard asks in step 2 for the "Development component" and WebDynpro    Application. But where do it get this information? Indifferently what path i enter, it only returns an error the the object is not available on the server.
    EDIT: The path to the webdynpro application is something like this: http://host:port/webdynpro/dispatcher/local/WebDynproUITest/UITest
    kind regards,
    Matthias

    Hello Dipankar,
    thx for the blog! This really helped a lot!
    The problem is, that you cant test the WebDynpro as a stand-alone application. What would be the best way to develop a WebDynpro Application for GP?
    Is there a way to start with a 'normal' WebDynpro Application and convert this when finished in a "guided procedure ready WebDynpro for CE Application"?
    I think i will contact you next week with more questions, for now on its weekend
    regards,
    Matthias

  • How to call WebDynpro application from an external application

    Hi All,
    I have an external application, from which an existing webdynpro application should be accessed.
    Is there any way i can access WebDynpro application through an URL, so that i can access the same from the external application.
    I have to pass a parameter also in the url from extrenal application for which that data should be displayed.
    Thanks
    Supriya

    You can call a web dynpro application from an external app by using the web dynpro application url.
    Go to WD application in studio and look at the properties tab, you will find the url.
    It should be something like this:
    http://<host>:<port>/webdynpro/dispatcher/<namespace>/<dc name>/<application name>
    MLS
