URGENT!!! how to check whether file exist or not on client side?

hello,
i am building appilication using JSP and javabeans.
Problem is my application is like on server files are there for say colors and their corresponding car image in that color.so when i move my mouse over that particular color ,its corresponding car image is displayed.
now say someone has deleted that corresponding car image file but image of color is there...........
so i have to handle such excpetion.
like if corresponding car image for that color is not there then that color image should also not be displayed.
i dont want to do this checking on server side.
pls help me!!!!!!

You don't have access to the client files. It is a security violation in a normal internet environment. Imagine what people could do to your computer if they could see everything on it.

  • How to Check Images File Exist? in different server

    Hi,
    I have 10 different coldfusion server.
    for example 9 server is for the web application site - for
    example
    http://myserverone/studentweb
    the other one is for images website, just for displaying
    student picture - for example
    http://myserverimage/studentpicture.
    the purpose of this website is to display student picture
    that i store as gif files.
    from my studentweb website i will call the images from
    studentpicture website as source for my image placeholder.
    for example this is my code i'm calling form
    http://myserverone/studentweb
    website:
    <img src="
    http://myserverimage/studentpicture/#studentnumber#.gif"
    alt="" name="studentpicture" width="160" height="200">
    my problem is, if there is no specific student picture in my
    studentpicture website, then the placeholder will display an X (
    mean the images not found )
    how do i prevent the X to display?
    how do i using coldfusion or any kind of way to check if the
    images exist on that website ( different server ), so if the images
    is not found, i can display a default images? i can do this if i'm
    calling the website in the same server, but not using a different
    server.
    this is like using other website images for your own personal
    website and sometimes the owner delete the images from their
    website, and i want to display my own images if that images been
    removed from the source website.
    anyone have done this before?
    thanks for suggestion and guide...

    1. Use CFHTTP with method="HEAD".
    2. See, if the HTTP status code is 200.
    The head-method is of course more efficient, as it doesn't
    need to "get" the message body. However, a status code of 200 is
    possible even when the requested image file is no longer on the
    server.

  • How to check Whether the File is in Progress or used by some other resource

    Hi All,
    I am retrieving a file from the FTP server using Apache commons FTP.
    I need to check whether the file is fully retrieved or in progress.
    for now i can able to use the file which is partially retrieved. it is not throwing any file sharing exception or i am unable to find whether it is in progress.
    How to check whether the file is in progress ? or The file is accessed by some other resource ?
    Pls Help me.
    Thanks,
    J.Kathir

    Hi Vamsi,
    Explicitly such kind of requirement has not been catered and i dont think you would face a problem because any application that is writing to a file will open the file in the read only mode to any other simultaneous applications so i think your concerns although valid are already taken care off .
    In the remote case you still face a problem then as a work around. Tell the FTP administrator to set the property to maximum connections that can be made to ftp as one. I wonder if you have heard of the concept of FTP handle , basically the above workaround is based on that concept itself. This way only one application will be able to write.
    The file adapter will wait for its turn and then write the files.

  • How to check whether the system has eclipse environment: urgent

    Hi gurus
    can you please tell me how to check whether my crm system has eclipse envirionment.
    Thanks

    There is no way to check whether a system is used productively or not, I believe what you mean is checking a client is productive or not in an ABAP-stack based system. Remember although a SAP ABAP system is identified by a SID but from a business perspective the system is recognized by a client, as it is a unique business identity.
    Thus, to check whether the client is productive or not in txn SCC4 check the role of the client, it will show you the correct status. The data of SCC4 is stored in table T000, you can also opt to check that.

    Hi
    You can use Win_Api_Utility.Copy_File cmd. IF the file does not exist r the file was not copied to the destination properly, it will raise no_data_found error. See Forms help - Find option for syntax & more details.
    I've used it & works well.

  • How to check whether the Application Server directory exits or not

    Hi,
    I have a selection screen in which I give the Application server file name(UNIX file) as input. Here, I would like to check whether the Server directory exists or not.
    Let us say, the path I gave in the selection screen is /usr/sap/tmp/testfile.txt . Here, the file name is testfile.txt and the server directory is /usr/sap/tmp . I would like to check whether this directory /usr/sap/tmp exists in the server or not. I am not bothered about the file name as I am going to write data into the file. I am mainly concerned about whether the directory exists in the server or not. and one more thing... this is the Application Server path not the Local path.
    Can anyone help me on the same how to check whether the server directory exists or not.
    Thanks in advance.
    Best Regards,
    Pradeep.

    Also you can use the FM EPS_GET_DIRECTORY_LISTING for this purpose.
      Store the directory name
        l_dpath = p_file+0(l_no).
      Validate the directory of the application server
        CALL FUNCTION 'EPS_GET_DIRECTORY_LISTING'
          EXPORTING
            dir_name               = l_dpath
          TABLES
            dir_list               = l_i_dlist
          EXCEPTIONS
            invalid_eps_subdir     = 1
            sapgparam_failed       = 2
            build_directory_failed = 3
            no_authorization       = 4
            read_directory_failed  = 5
            too_many_read_errors   = 6
            empty_directory_list   = 7
            OTHERS                 = 8.
      If any problem occurs with the directory then display proper
      error message
        IF sy-subrc <> 0.
        Display error message
          MESSAGE e018 WITH 'Problem with directory entered'(008).
        ENDIF. " sy-subrc <> 0
