Also, I missed another point.
In the folder c:\dbdata I have a number of CSV files on the user frontend. I would like the BSP application to get the list of files in the folder and process them one after the other. How can I get the list of files on the folder in the user PC and how to process them one after the other.
I want the form to display only the default folder and once I press on upload it must process all files and display the status of processing on the same page.
Please kindly share ideas how I can implement this app.
Thanks
Karen

  • How to set the default settment rule for the same kind project.

    hi experts:
       the project of the same kind of the project profile have the same settment rule to one account (G/L).
    how to set the default settment rule for the project of  this kind of the project profile.
    regards

    Hi,
      You need to define the settlement profile and allocation structure.
    next you need to define the  Strategy for settlement rule.
    navigation-PS> costs> automatic and periodic allocations> settlement> Settlement rule for WBS
    --> Define strategy for settlement rule.
    Select the strategy and click on settings. in that new entries, check the Acc Assg element, enter Settlement profile and mention accass category as reposnsible cost center.
    Save this transaction.
    Now create a project assgin responsible costcenter for the WBS element in the project buider and save the transaction.
    Now run CJB2 transaction for the project, settlement rule will generated automatically.
    even you can configure the same for profitability segment.

  • How do I set the default file path for the Place command?

    I keep my graphics files for each document in a particular folder. Every time I open an existing InDesign document and place a new image I have to browse back to that location - even though all of the previous images in that document came from the same folder. InDesign does not remember the file path that was used previously in the document. This is very annoying.
    IS THERE A WAY TO SET THE DEFAULT FILE PATH, OR LOCATION, FOR IMAGE FILES?
    I have looked through the preferences, searched the forums and internet, but I have not found any reference to setting default paths. Is there a setting like the one in MS Word called "File Locations" on the Options toolbox?
    Thank you.

    Since you're working in ID on Windows, you can take advantage of a neat trick in Windows. Copy the file path out of the File Explorer address bar and paste it directly into the Place filename field. That will jump you directly to the desired volume. For example, let's say I want to place a graphic located at X:\PS Jobs\May PS\709672bp\Working Source Files\Links. I copy that entire path from the File Explorer address bar, go to InDesign, select File|Place, and press Control + V to paste that path into the filename field. I press the Open button and Shazam! I'm there instantly, without a bunch of navigation.
    You can do the same thing in the File|Save As and File|Export fields. Let's say you want export a PDF file from InDesign to the volume X:\PS Jobs\May PS\709672bp\Working PDF Files. First copy the desired file path from the File Explorer window. In InDesign, select File|Export, click anywhere in the filename field, and press the Home key to move the insertion point to the front of the filename. Press Control + V to paste that path in front of the filename, then add the backslash character (\). The filename will now look like this: X:\PS Jobs\May PS\709672bp\Working PDF Files\Filename.pdf. Press the Save button to bring up the Export Adobe PDF window. Select your desired PDF preset, press the Export button, and the PDF file will magically appear in the desired volume.
    This sounds really complicated, but it's not. In practice, it only takes a few seconds. I probably save an hour's worth of needless navigation every day with this technique.

  • How to set the default maximum size for java's heap?

    Hi!
    Im trying to set the default max size for the java heap - but not from the command line.
    I would like to set it higher as default on my computer.. how can I do that?
    thanks!

    >
    ...You may increase the memory heap only when you're launching a new JVM.>Much like IWantToBeBig does.
    OTOH, it this is an app. with a GUI, it is easier to launch it using webstart, and request extra memory in the JNLP descriptor (the webstart launch file).

    In Tiger server there was a place to input the URL of the default web page for all browsers when users logged into network home folders. This was really helpful and saved a bunch of bandwidth and class time. Is there any way to do this in Leopard server? If so, please point me in the right direction.

  • Urgent!How to set the default selected date for an OAMessageDateFieldBean

    Hi,
    There is messagetextinput on the page.the dataType is Date.
    if I do not input anything on this messagetextinput ,when I click on the date icon,the default selected date is today.
    But I want to set the default selected date base on another messagechoice.
    Is that possible?
    binghao.

    Sumit/Binghao,
    When u set deafult date in the OAMessageDateFieldBean, the OAInlineDatePickerBean (which are referring as datepicker popup windows), takes the default value from OAMessageDateFieldBean.
    If you explore OAMessageDateFieldBean in framework, u will find its nothing but a onClick js event is called on the imageicon attached with messagetextinput bean(in case the type is Date) and OAInlineDatePickerBean is opened in a modal js window.
    So, here is code for setting default value both in both in OAMessageDateFieldBean and OAInlineDatePickerBean :
    OAMessageDateFieldBean dateField = (OAMessageDateFieldBean)webBean.findIndexedChildRecursive(<item id>);
    dateField.setValue(pageContext,new Date(100, 06, 04)/* 4th July 2000*/);
    One more important thing, here Date class is java.sql.Date.I hope i am clear.

  • Interactive Form Element 7.1:  How can I set the default file name?

    I am using Interactive Form Element with 7.1 to display a pdf.  When one clicks the save button in Adobe's toolbar, the dialog defaults the file name to "F.pdf".  Is there a way to default this to a different value?

    Making customisation from the default profile is generally considered poor practice and quite often doesn't work out as planned. (If you're interested in some more information on this, [http://mockbox.net/windows-7/227-customise-windows-7-default-profile.html see here] see here)

  • Setting the default Output Name for the Export Media dialog

    In File | Export | Media the Export Settings always show the wrong Output Name, from a project I did several days ago. If I change it for this export, the wrong path just comes back again for the next export.  I don't know how I accidently  got it set for the earlier project.  I don't see any way to set it. Could someone tell me where this is set?  I'm running PrPro CS4.

  • How to get the trace file name for current running application?

    Hi, I want to know if it is possible to get the file name directly for current running application instance which is launched by javaws.
    There is a property "deployment.user.logdir" tells the log directory, it would be great if a file name property
    is available. something like "instance.trace.file".
    Our application wants it because we would like our client send use the application log by clicking a "send error"
    button, the codes finds the trace file and compress it and send it by using a smtp server.
    In 1.5, we can do it by using a shell program.

    I found other asked it before, but I tried to set both properties, but neither works. my sun JRE version :java version "1.6.0_04"
    <property
    name="deployment.javaws.traceFileName"
    value="abcfefsfdsf"/>
    <property
    name="deployment.javapi.trace.filename"
    value="235235235"/>
    But it always write to one trace file with name lik javaws63645.trace

  • How do I set the default print margins for ALL printers in mozilla.cfg

    How do I set the default print margins for ALL printers in mozilla.cfg, even ones that are not yet installed / connected to the computer?
    I'm trying to install firefox with MDT and apply certain print options, but the printers themselves are connected at a later stage so the print.printer_myprinterhere cannot be used.

    Best answer I could find: [https://mike.kaply.com/2012/03/16/customizing-firefox-autoconfig-files/#comment-132668]
    If you can figure out how to add the printer name, this can be used to lock the margins.

  • How do I set the default welcome page for PUBLIC user

    gurus,
    i'm using -
    Oracle 9i Database
    Oracle 9ias Portal Release 2
    QUESTION => how do I set the default welcome page for the PUBLIC user.
    i did the following to achieve this -
    1. logged into portal
    2. clicked on builder
    3. clicked on administer tab
    4. selected PUBLIC user in the Portal User Profile portlet
    5. went to the preferences tab
    6. in the default home page selected a custom page group
    7. logged out of portal
    8. open a new browsere session
    9. type the portal URL and i get the login page ....??
    i'm unable to understand this behavior ... shouldn't i be getting the page group that i set for the PUBLIC user in step 6 above ....
    the second QUESTION is => when the user logs out he/she should see the PUBLIC page set in step 6 above ... but, instead the user sees a page that is as follows -
    Partner Application Name Logout Status [Logout Status]
    Oracle Portal (portal) logout status
    The SSO Server (orasso) checkmark
    buzz.resva.trw.com:7778 checkmark
    infrastructure.happy.resva.trw.com checkmark
    portal1.buzz.resva.trw.com checkmark
    portal2.sylvester.resva.trw.com checkmark
    sylvester.resva.trw.com:7778 checkmark
    so, how can i set the default page for the PUBLIC user and also a page when he user logs out.
    ideas anyone ....?
    thanx a bunch.
    hero

    Hi,
    The sequence of operation you are doing to set the home page for public users is correct. You are getting the login screen as the "custom page group" selected as "home page" has not been granted to public.
    Also, while logging-out, it is normal behaviour to get the screen where it shows the list of partner applications from where user has been logged-out. When you click on "Return" button, you will get to the "home page" set above.
    Hope it clarifies the things.
    Regards,
    Ved
