WebDynpro: Problem with opening the generated xls file

Hi,
     I am new to the WebDynpro for Java world.
I am trying to learn by referring to the sample tutorials on SDN.
I tried executing the sample project for the exporting to excel.
After I down load the generated xls file to my computer and try opening it I get an error message from excel : "Microsoft Excel Viewer cannot open files of this type".
I get the same error message if I try opening the file directly instead of first downloading it.
     Please help me out with possible reasons for this.
Thnx in anticipation,
Pravesh Puria.

Hi,
Is the content type : application/vnd.ms-excel.
I guess the problem is with identification of the content type.
Regards,
Sujana

  • Problem with opening a dmg downloaded file.

    I have a problem with opening a dmg file type. Example. I down loaded an update for Onyx. The download is placed on my destop. OnyX.dmg. When I click the file, disk utility opens up. I click OnyX.dmg and it attaches the image. I then have the OnyX disk image on my desktop. I click on OnyX.pkg and get the message "There is no default application specified to open the document "OnyX.pkg"
    I remember when I 1st installed the program months ago. I just dragged the icon to the applications folder and was done.

    There is something rather odd with your defaults for opening things. Double clicking a .dmg file should cause it to mount automatically using DiskImageMounter, and double clicking a .pkg file ought to cause Installer to run. DiskImageMounter is here:
    /System/Library/CoreServices/DiskImageMounter
    and the Installer is here:
    /System/Library/CoreServices/Installer
    You can use GetInfo to assign those programs to those file types. You might consider fixing your LaunchServices database. See the discussion thread here:
    http://discussions.apple.com/thread.jspa?messageID=5744911
    Using OnyX is probably the easiest solution.

    whever i refresh the entire application in the tomact then its been recognizedMaybe you're creating and downloading it asynchronously so that the creation of the file isn't finished yet while you're about to download it.

  • Problem with opening the .fmx file through hyperlink

    I am trying to open a .fmx file through hyperlink. After clicking on the hyperlink a dilogue box opens up and asks for "open from the remote server", "save on the local disk" and cancel. If I click on open the .fmx file opens up and applications starts working.
    Problem is "I do not want this dialogue box to be opened after clicking on the hyperlink". I tried to change the mime type and changed the setting of Internet explorer. But it does not work.
    Any suggestion will be appreciated.
    thanx in advance

When I open pdf file in adobe acrobat everything works great, but when I open second file, I receive this problem that Adobe acrobat stopped working and I receive this error : nvd3dum.dll.

    Hello Dave
    the Problem affects all Uniplot 3d Files. I start with an Excel or .txt file with 3 columns and uniplot creates an engine diagram similar to this one: http://www.uniplot.de/documents/de/_images/Uni_BSP7-2.png
    Uniplot can Export this as a .u3d but it can not be opened with Adobe. Then I tried to open the .txt.file with MeshLab. I can see the correct Points (which Uniplot uses to create the engine diagram) but of course they are not connected. If i Export those Points in MeshLab as a .u3d file, Adobe can not work with it.
    I do not know how to deal with this Problem. Do you have any suggestions?
    Thanks in advance for your help

  • Problems with opening jpg or tiff files in my own file groups

    I have installed Aperture 3.1 from the apps store, but it does not open any of my jpg or tiff files. They are not stored in iPhoto or any other Apple feature, but in my own file system based on types and purpose. They are all scanned analog images made long ago; I do not use a digital camera

    Hello George,
    george e.todd wrote:
    First there is no error message - but BTW I did not have Aperture beforhand; this is only the 3.1 downloaded from the App store. Could that be the reason?
    It is a pity, that there is no error message, so we just have to guess.
    The App-Store version should work just like the boxed version.
    I'll check the info panel of any of my images, but as I've never set up anything like sharing or permissions, etc.,
    You do not have to set up permissions to have problems with permissions. With each file in MacOS there are stored acces rights, and some times these are wrong, if the files are created by certain apps. Then you need to correct those.
    But as Preview can open your pictures, then there seems to be no permission problem.
    To me it seems likely that the images use a codec, that Aperture does not understand.
    I would like to make sure that you can import  any pictures at all into Aperture.
    Could you try to take a picture with "Photo Booth" and try to import it to Aperture?Photo Booth pictures should be imported without problems.
    If you can import from Photo Booth, then your image codecs probably are the problem, and you need to find out what is special with your pictures, maybe you can post one as link for us to inspect.
    if you cannot import any pictures, then probably something is wrong with your Aperture installation. In the latter case you might wish to perform the basic trouble shooting procedure

  • Problem with Opening the Database

    Dear All,
    I am learning myself Backup And Recovery.
    I messed up with Redo Log files and now the database is not opening.
    What actually I did is
    1) I got 2 redo log groups with I member file in each group.
    Group 1 (redo1) & Group 2(redo 2)
    2) Then I shutdown the database "Shutdown Normal"
    3) Then I removed the one redo log files. (redo 1) "rm redo1"
    4) Now I tried to open the database. It didnot opened as redo 1 is not available
    5) Now I Added one group 3 when the database is in mount mode (alter database add logfile group 3 ...)
    6) Now when I tried to drop the redo log file, I am getting the below error
    ORA-01623 log 1 is current log for instance orcl (thread 1) - cannot drop.
    7) So Now I am not able to open the database
    Can Anyone please help me out.
    Appreciate any help
    Thanks & Regards
    Madhu K

    Madhu,
    Can you try recreating the controlfile ? All it does is resets the redologs (reinitializes them). There wont be any dataloss. You can open the database using "alter database open resetlogs" after you recreate the controlfile.
    Have you looked into the backup and recovery case scenarios. They covered loss of redologs also.
    Since you are learning by yourself, i hope you are following Official Oracle guides. They are your bible when you practice things for the first time.

  • Problems with opening Canon T4i CR2 files in elements 10

    I have a cannon rebel T41 and Adobe elements ver 10, ive been taking photos in RAW format but cannot open them in the elements software, the files are saved as a CR2 file can anybody help please.

    The T4i was first supported by ACR 7.1.  The last ACR version supported by PSE10 is ACR 6.7.
    This means you need to update your PSE to 11 or 12 to work with T4i CR2 files.  Or maybe buy Lightroom, which is about the same price as Elements but contains all the raw adjustments not just the few in the Element’s-hosted ACR plug-in.

  • Problem with opening a indd file in CC 2014.

    When I'm trying to open a 5.5 .indd-file in CC 2014 on my Windows computer, I get this error message: 'Either the file does not exist or you do not have permission to open it or the file is used by another program'. However my collague has no problem with opening the document on his Mac computer. I guess it has something to do with a kind of setting in my CC 2014. Can anyone help me?

    Nothing to do with ID. It really means what it says - your file permissions are hosed and it being an ID file this could include things like fonts or placed images referenced within it.

    I have a problem with opening downloaded files from the internet; zip types. Can you tell me an app to open these types of formats of files?

    It should unzip if you double-cick.
    What are you seeing happen when you do that?
    Select a .zip file in the Finder and Get Info (cmd-i). What is set for it to Open With. It should be Archive Utility.

  • Pdf causes problem with opening files: help, please!

    The operating system on my computer is Windows xp and I use Adobe version 11.0.6.
    I am having a problem that arises when I get a warning message (particularly when opening pdf or xls files): "AcroRd32.exe - Application Error: The exception unknown software exception (Oxc0000409) occurred in the application at location 0x00411e0b". I am then unable to open most files - pdf, xls, Word etc. - until I switch the machine off and then on. I have discussed this problem with Microsoft, who eventually said that it seems to be caused by something related to Acrobat software.
    I should be grateful for advice or help from any participant in this forum.
    Many thanks in advance.

    To test the automount hypothesis, you could create
    a new user with a home directory someplace completely different and NFS-free, like /opt
    useradd -m -d /opt/testuser -s /bin/bash testuser
    passwd testuser
    Then login to CDE as the user.
    It does sound like there's something broken with $HOME/.dt
    cheers
