  • How to read a .csv file(excel format) using Java.

    Hi Everybody,
    I need to read a .csv file(excel) and store all the columns and rows in 2d arrays. Then I can do the rest of the coding myself. I would like it if somebody could post their code to read .csv files over here. The .csv file can have different number of columns and different number of rows every time it is ran. The .csv file is in excel format, so I don't know if that affects the code or not. I would also appreciate it if the classes imported are posted too. I would also like to know if there is a way I can recognize how many rows and columns the .csv file has. I need this urgently so I would be very grateful to anybody who has the solution. Thanks.
    Sincerely Taufiq.

    I used this
    BufferedReader in = new BufferedReader (new FileReader ("test.csv"));
    // and                
    StringTokenizer parser = new StringTokenizer (str, ", ");
                    while (parser.hasMoreTokens () == true)
                    { //crap }works like a charm!

  • How to write file at server end?

    Hi,
    I use a af:inputFile component to receive uploaded files. And want to write files to the directory of server. However, when execute java.io.File.createNewFile(), it throw exception. How to resolve it?
    import org.apache.myfaces.trinidad.model.UploadedFile;
    import javax.faces.event.ValueChangeEvent;
    import java.io.InputStream;
    import java.io.File;
    public class UploadFileHandler {
        public void doUpload(ValueChangeEvent event) throws IOException {
            File file = new File("C:\temp.txt");
            *file.createNewFile();* //Error happen here.
    }

    Hi Cheney,
    It is good practice to use System.getProperty("file.separator") instead of hardcoding "/" or "\" .
    Though your issue is resolved by using "//", you might want to consider changing to the above.

  • How to write file to server side?

    hello,
    Could anyone pls help me...
    I just want to see an example how can I write to a file that is placed at the server(save place as the applet).
    p.s. I have been successfully read a file from there...
    Suppose I have signed the applet (self-signed), anymore security problem I need to pay attention to?
    Thanks a lot!!

    hi mandy, from the applet u can send the file to be written into the server to a servlet running in server and the servlet can in turn write the file into the servlet. by applet - servlet communication, u can easily read and write files to the server.

  • Cannot Convert PDF to Excel Format (.xlsx)...

    For over a week, I've been unable to convert a PDF to .xlsx Excel format; after considerable wheel spinning, I get "An error occurred while signing in." Working with support, I uninstalled/reinstalled Adobe Reader; the support tech reset all the preferences, all to no avail. I'm on a Mac under OS 10.9.5.
    My case number with them is 186473209; it's been advanced to a higher support level.
    Today, I had a friend attempt the conversion on his Mac, which is running Yosemite. He logged on with my info and was able to effect the conversion.
    Could that be the solution, or might there be something else going on with my Mac that's causing the problem?

    Thanks,  Sara. I have attempted to effect conversion using other browsers,
    including with Firefox, clearing all caches etc. The reason I tested with
    Maxthon is that I didn't mind clearing it as well. Here's what I just sent
    to Rahul:
    I thought I told you that I have attempted the conversion using four different
    browsers, all with the same failed result. These were Chrome, my default
    browser, Firefox, Safari, and Maxthon. Per an Adobe techie's recommendation, I
    cleared ALL cache and history as a test in both Firefox and Maxthon.
    As I also told you, although I eventually get logged in, it takes inordinately
    long to do so. When I select to begin the converting process, I get stuck at
    this window with the "Continue" button grayed out; can only "Cancel."
    Maybe I neglected to tell you that my friend is running Yosemite while I'm
    still on Mavericks. A technician at Adobe told me that they think that may be
    the issue.

  • How to write files to the filesystem with portal/plsql

    Hi,
    is there a way to write files to the filesystem via Portal?
    Or can i call an external programm (perl, php) to do so, while portal writes further information to database?
    thank you for the help

    Hi Ralf,
    my primary task is to publish download-links to files stored ... somewhere as a linklist. I tried to store and download files to/from the database but i cant get it to run. Upload works, download doesn't.
    (i'm not talking about a single form-query-download-link! I need a report-like linklist)If you want to do this you'll have to write some code but sure it's possible - i did it myself.
    The links in the link list in your report should call a stored function retrieving the files from Wwdoc_document or whatever is the document table defined in your DAD. Simply select BLOB_CONTENT into a BLOB variable from the table, provided you know what file to read :-) The function would then read the BLOBs and send them to the client's browser via DBMS_LOB - it's poor design but it works just as smooth as it could and it's really performing. This would simply display the file into your browser or prompt for file save location, depending on what browser you are using and its client settings.
    I guess this is not so clear, if you want some more details feel free to e-mail me at [email protected]
    Another way would be to use wpg_docload to both download and upload files to/from the DB.
    Now i try to figure out if it is possible to store the files to the filesystem and write only additional info like description or path into db.Again, yes, it is. I can't recall exactly how I did it ^_^ but the trick is to create a virtual directory in the DB - pointing at a physical directory on the file system you want to write to, and you have to have full read-write permission on the directory itself, and its path must be included in the utl_file_dir database parameter. Then you use both COM Automation or UTL_FILE to write files.
    would it be possible to let a portal-form write info to the db and then pass the file to a php-script?

    1) Well I find it rather convenient to deploy a web app as just one file rather than a bunch of files. For deployment it's much better. However I prefer using expanded files when developping (to use auto reload in Tomcat for example)
    2) It is a bad idea to upload files inside your webapp's context (ie: in it's deployment directory) because one day an uninformed system administrator might come and redeploy the web app and therefore delete all your uploaded files (believe me, I've already experienced this!)
    What i do usually is upload it in a completely different directory, something like /uploaded_files. Your uploaded files are therefore completely independant from your webapp
    However it is a bit trickyer to get those files back. Let's take the example of image uploads. You have 2 ways of proceeding:
    - the easiest : configure your web server (apache etc...) to redirect a certain url to your external directory. For example the /upload url will point to a /uploaded_files directory. This is easier to do and the fastest way to serve images but not always the best solution: you are dependant on the web server's configuration and you can't control the visibility on your files (no security constraints, anyone can see your uploaded files if they know the url).
    - you can also write a servlet which will load the file as an array of bytes and send it back in the response.
    You can call it this way :
    <img src="/serlvets/showmyimage?path=uploaded.gif">
    in this way you can control your uploaded files better: you may want to define security constraints on the visibity or not of uploaded files depending on the user which has logged on the site.

  • Urget::How to download in excel format  in Background

    hi,
            i was using GUI_DOWNLOAD  in a program to download into excel format. but now the user wants to run this in background mode .But gui_download doesn't support the background .can u suggest me any other way to download in background mode into excel format.
    it's urgent .please help.
    Thanks in advance .

    Hi Rasmi,
    In background you can only download it to application server and not on your PC.
    If its ok then you can use OPEN DATASET....CLOSE DATASET to do that.
    Once its downloaded to Application server you can download that into your PC.
    Hope This helps you.

  • Help with saving time stamps to "write to measurement file" excel format.

    I am having problems saving the timestamps from my data to the write to measurement express vi for excel.  My incoming data is converted from dynamic data to a 1d array for processing, which I understand you lose the time stamp data. I added a new array for time stamps but this array then cannot be converted back to the dynamic data that is requested to go into the write to measurement file express vi.  I would prefer to leave the data in an array to be saved rather than converting it to a waveform so is there any way to add the time stamps from my 1d array back into the write to measurement file? 

    I set it up to build a waveform now but I am still having issues with it saving the correct timestamp.  The time just incriments for every second (as it did before converting the dynamic data to the waveform). I attached a screenshot.

  • How to write to Excel values from following measurements to neighbour cells?

    Hi,
    I build app for some measurements, "end" of this app:
    As you see I have few arrays (with 12 rows). I want to eksport 2 arrays to Excel. In upper case results looks like this:
    And everything is OK, this I want, but... When I run app next time I want to save this next results in columns C and D in the same file. Next app run - columns E and F, etc. How can I do this?
    Regarsds

    Express VIs (such as Write to Measurement Files) are basically "shortcuts" designed to provide a quick fix, but rarely allow much flexibility, such as allowing you to determine where to put your data on subsequent writes.
    What you are trying to do can be done with the Report Generation Toolkit, which includes components that directly link to Excel (I'm not sure if Write to Measurement File actually uses Excel or simply writes data in an Excel-compatible format).
    However, there's a minor complication.  The task you have stated is to write columns, with subsequent columns going to the right of existing columns.  There's a function in the Excel-specific sub-Palette to find the last row, which you can use to write rows, with subsequent rows going below the last row.  It's not too difficult to use the functions in the Report Generation Toolkit to basically do what you want, but it isn't exactly straight-forward.  It would be a lot easier if you could write your data in rows ...

  • How to write file in Applet

    I have a code:
    URL url = new URL("http://hostname/file.txt");
    URLConnection con = url.openConnection();

    String s = "Test";
    byte[] b = s.getBytes();
    out.write(b);
    out.close();
    But it does not create or save into file.
    Please tell me how to solve it.
    Thanks.

  • How  applet write file in local system by URL instead of FileOutputStream()

    hi,
    how can applet write a file in local system through URL instead of FileOupStream()
    plz.....plz.....plz......
    URL url = new URL(" file://c:/temp.txt");
    in this url how applet can write
    plz....

    URL uses http to cummunicate, this means you can send and receive data using the http
    protocol.
    The OS doesn't do anything with this, you need a http server to interpret these messages
    and take appropriate action (with server side script or CGI).
    So if the client has a http server installed and has server side script thad does
    something with your http request (that's what a url does) than it is possible.
    Since both having a http server , server side script and or CGI have nothing to do with
    signed applets I will not answer your question here.
    But the mail reason I won't answer it is because it makes no sence to use a URL to write
    to the local file system.

  • How creat flle and and how to write file network

    eg:\\bissstorage\Backups\sudhir
     i want to write inside ths folder...how to get path
    i tried this one 
    iFile = OpenFile ("\\bissstorage\\Backups\\sudhir\\TransducersDetails\\TransducersDetails.txt" , VAL_READ_WRITE, VAL_APPEND, VAL_ASCII); 
    but its not working im using cvi 5.5
    thank you
    Sudhir

    In a network pathname, some backslashes are doubled due to UNC naming rules: you must reflect this in your string, considering that each backslash character must be doubled to be used as is and not as an escape marking; that is, this string should work:
    iFile = OpenFile ("\\\\bissstorage\\Backups\\sudhir\\TransducersDetails\\TransducersDetails.txt" , VAL_READ_WRITE, VAL_APPEND, VAL_ASCII); 
    The same applies in case you want to build up the path with MakePathname: in this case you should do the following:
    char    file[512];
    MakePathname ("\\\\bissstorage", "Backups", file);
    MakePathname (file, "sudhir", file);
    MakePathname (file, "TransducersDetails", file);
    MakePathname (file, "TransducersDetails.txt" , file); 
    iFile = OpenFile (file , VAL_READ_WRITE, VAL_APPEND, VAL_ASCII);
