Webutil Creating file on Client issue

we are planning to us webutil. But when writing file to client is ok for us to write 50 lines but as we write more lines to file on client run success fully but file remains empty nothing written to file. and next call to use of webutil functionality forms hangs. and we have to kill browser to get back browser.
Is there any parameter in webutil configuration that control size of file to written on client.
Creating file and then transferring works great

I was having the same problem as the original poster: Using WebUtil.client_text_io to write a file to the client that had more than a handful of lines. The file would appear on the disk, but the file size stayed at 0. It did not appear to throw an error, but the next time a WebUtil call was made, the entire client hung and became non-responsive.
I tried your suggestion below, where the file is written on the server and transferred to the client using the WebUtil file transfer ability. It worked great, and it is fast. Thanks!

  • Is there any way to create files on client

    Hi,
    In a servlet class, I use java.net to get the client IP address, and I shared one folder on the client computer. But I got a java.io.IOException: Access is denied error when I was trying to create a file in the shared folder.
    I changed the java.policy to let the class have permission to write files. Any one can give me some suggestions?

    No server-side solution can help u! u should just use Applets.
    ( or any fat-client like a Java Application )

  • Opening CS2 created files in CS4 issue

    we commonly work with foor plans which multiple laters of data.  We are noticing that nearly all of the files created in cs2 are displaying automatically moving layers when opened in CS4.  A layer of symbols or objects simply "shifts" to an alternate location and there is no easy way to fix it.  We are unable to identify a fix tho these files other than locating an old verison of cs2 to open them with.
    any ideas guys!  much appreciated!

    Further to my earlier reply I suddenly remembered that I had created the JPF
    files in Photoshop 3 Extended which fortunately I still have loaded on my
    computer. I was able to open the JPF files into that and save the them as
    JPEG files which I can now open in CS4.  Problem solved !! Thanks again for
    your help. Learning how to use and manipulate Photoshop is a continuous
    process and the interaction between Forum users is invaluable.

  • Open bat file on client machine using webutil

    Hi all.
    I'm on devsuite 10g.
    I want to run a bat file on client machine using client_host function of webutil.
    I have tried first to execute the bat file with mouse double-click in order to check if it is ok, and it works.
    Now I want to execute this file from my form using webutil.
    Here is my code:
    --> with this code I select a file from client machine
    Declare
         LC$Fichier Varchar2(1000):=null ;
         PC$Filtre Varchar2(2000) := '|All files|*.*|' ;
    Begin
         LC$Fichier := WEBUTIL_FILE.FILE_OPEN_DIALOG
         null,
         PC$Filtre,
         'Seleziona un file da caricare'
    If LC$Fichier is not null Then
    :output.apri_file := LC$Fichier ;
    End if ;
    End ;
    --> with this code I execute the file that I have opened

    BEGIN
         Cmd := 'cmd /c start "" "' || :output.apri_file || '"' ;

    When I execute my form I have this error:
    Exception in thread "main" java.lang.NoClassDefFoundError: ....folder of file opened.
    Can anyone help me to solve this problem??
    Thanks in advance,

    Hi Tony.
    I have tried to run my bat file with double-click and everything is OK.
    When you say the DOS window opens for few second, is your batch file being executed?? did you see the results??
    The answer in NO for both of your questions.
    If I try to drag and drop the file I have error.
    How can I attach an image to this post, so that you can see the error??
    Thanks,
    FabrizioThis seems like a directory or OS level permission issue on the batch file, What is the error you got when you tried drag and drop the batch file in an DOS window???
    I think you need to upload the image to a site and use the markup for the image, include the full URL of the uploaded file between ! (exclamation marks) something like ! http://../post.gif ! without the spaces.

  • Applet-Servlet - Creating a new file on client's mashine

    Hi all!
    I need to write a program, that will get a data from client through Applet text fields and save it to a new(or rewrite existing) file on client mashine. To save it, I want to use Servlet, because Applet can't do this because of security restrictions. So I think of sending data from Applet to Servlet, which will save it in a new file (will download this file back to the client's mashine).
    I found the following code in forums to download a file from server to client:
    import java.io.*;
    import javax.servlet.*;
    import javax.servlet.http.*;
    public class OutputFileOnBrowser extends HttpServlet {
    public void service(HttpServletRequest req,HttpServletResponse res)
    throws ServletException, IOException
    res.setContentType("application/x-filler");
    res.setHeader("Content-Disposition", "attachment; filename=out.fif;");
    ServletOutputStream stream = res.getOutputStream();
    BufferedInputStream fif = new BufferedInputStream(new FileInputStream("in.fif"));
    int data;
    while((data = fif.read()) != -1)
    stream.write(data);
    fif.close();
    stream.close();
    but I don't understand, does it automatically downloads the file out.fif to client's disc and in what path? I tried it, and it did nothing. Anyway, this code doesn't fit exactly my purpose, because I have first to create the file.
    Could anybody help me please?
    Thank you in advanse!
    P.S. I've already wrote the Applet code, what I need now is o n l y the help with a Servlet part!
    Best regards.

    Thanks, but I want not client but servlet save the file automatically in a given path on client's mashine. Is there any way to do that?
    Thanks.

  • FND function to create .csv data file on client machine?

    Hello All,
    I am trying to create a concurrent request which when run by the user's creates a .csv file with data. I created a procedure in the database which run's when they run the conc.request.
    However is there any FND function or anyother function available that creates the data file on the client machine (either in their 'C:\') or in a share drive etc?
    Currently through the procedure, I am able to write the .csv data file to a unix directory to which users do not have access.
    Thanks,
    Chiru

    Chiru,
    Several options for you to consider are :
    1. If you want to have the csv on client machine: Make the program to create the csv in server with a constant name, eg : test.csv and create a dos command in client's machine that is could FTP to server, rename the existing csv file in client's machine and get test.csv from server.
    2. If you want to do in share drive : As long as the share drive exists in PC that can be used for FTP, you can create unix host script that can FTP the file to the windows server. For instance, create a generic unix host script that accepts parameter such as filename, and server destination, destination folder, unix login ,password, etc. This program will run in a request set after your concurrent program. If you search google I'm sure you will find samples of unix script that does this kind of thing.
    3. As per what Kevin said ,another options is to send the csv file using email to the recipients.

  • Webutil, syslib files one time download to client

    The below are the contents from webutil.cfg file. My question is do these syslib files need to be downloaded to the client, even if we are just using client_get_file_name, client_text_io routines of webutil?
    As per the notes on the webuitl.cfg file, only certain integration operations require this one time download , it doesnt say that all integration operations require the one time download.
    Thanks in advance.
    # 2. Installation Options
    # WebUtil needs to download some files to the client in order to perform
    # certain integration operations such as OLE or Registry Access
    # These files are downloaded the first time that you access one of the

    # You have to define the location of these files on the server
    # Details
    # syslib.location: The vitual path to the directory holding the
    # the webutil library files on the server side
    # this must either be an absolute URL or a url
    # URL that is relative to the documentbase
    # syslib.<os>.<package>.<n>: The name(s) of the libraries required for particular
    # webutil beans

  • Creating file in the client machine

    Hello All,
    In my jsp page, am writing data from database to an excel file and I want this excel file to be created in the client machine. I checked in the forums but could not find an apt reply.
    ie, when i click on submit button, i get the data from the database and put it in an excel file.
    any help would be appreciated.
    am realy struggling with this.
    any link to previous posts regarding this would be very helpful.
    thankx a ton,
    arun.

    you can't write a file from the server to the client. Such functionality would make it really easy to install virusses and such, don't you think? You can write the excel file on the server and then allow the user to download that file. This would mean writing the file to a webdir and then offering it as a link on a webpage.
    Check out the apache website for jakarta POI, which allows writing (and reading) of excel files.

  • Issue with creating Web Service Client using Oracle JDeveloper

    Hi All,
    I am trying to create a Web Service Client using Oracle JDeveloper. I set the Project compiler property to JRE 1.4
    When I run the web service client, it throws me bunch of errors saying:
    'Error(32,2): annotations are not supported in -source 1.4'
    I am wondering why JDeveloper is using annotations even after I set the compiler property to 1.4
    I am following this link to create the webservice client:
    http://www.oracle.com/technetwork/developer-tools/forms/webservices-forms-11g-094111.html
    Any help in this regard would be greatly appreciated.
    Thanks,
    Scott.

    Dear Shay,
    Thanks for your prompt response.
    You are right. JDeveloper 11g uses JDK 6 style annotations for the clients it creates. But you can change the JRE Version used at compile time by following these steps:
    1. In the Applications Navigator, right-click the Project Nanem node and select Project Properties... from the context menu.
    2. Select the Compiler node and check the Source Files and Generated Class Files dropdown lists. You may change these versions depending on the version of the JRE you are using with Forms to ensure that the compiled
    classes from JDeveloper can be read by the JRE used by Form.
    So I selected JDK version 1.4 there.
    Sorry that I did not mention that we are using Oracle Forms 10g. That is the reason I selected JDK 1.4
    Thank you.
    Scott.
