Upload unicode file and display content in a textarea

Hi all,
I am trying to do the following;
1. upload a unicode file (file with some non-english characters)
2. after uploading, read the uploaded file and show the content in a textarea in a jsp page.
I use struts in my project. I use class org.apache.struts.upload.FormFile for uploading the file. The upload works fine. I do the upload with help of FormFile's getInputStream method. When i read and display the content in the textarea, the content is displayed junk. But i tried to open the uploaded file, its fine. I mean it is just as my source file. Please help me out for reading the uploaded unicode and displayed in a textarea.
Below is the code that i use to upload the file;
File tempFile = null;
FileOutputStream fos = null;
InputStream is = null;
try {
     tempFile = "c:/ThaiText.txt";
     fos = new FileOutputStream(tempFile);
     is = theFile.getInputStream();
     // Transfer bytes from in to out
     byte[] buf = new byte[1024];
     int len;
     while ((len = is.read(buf)) > 0) {
          fos.write(buf, 0, len);
     logger.info("fileName$$=" + tempFile.getName());
} catch (Exception e) {
     throw e;
} finally {
}Below is the code that i use for reading the uploaded file's content and store it to a string. I set this string to a form bean's string property.
public static String readContentNonUTF8(String path) {
     FileInputStream fis = null;
     String value = "";
     try {
          fis = new FileInputStream(path);
          byte[] buf = new byte[1024];
          int len;
          while ((len = fis.read(buf)) > 0) {
               String tmp = new String(buf, 0, len);
               value = value.concat(new String(tmp.getBytes()));
     } catch (Exception e) {
     } finally {
          try {
          } catch (Exception e) {
     return value;

Thanks for your reply. You meant that both method also can used to upload file and submit data? How about if i want to use the first method to upload file and submit data? How can i upload the file by using first method?

  • Upload excel file and display content in sapui5 table

       how to upload  excel files and display its contents in the view of sapui5  table ,then  'create ' these data into the abap database using odataservice.
         Do you have any solutions ? I appreciate for your help.

    Two possible way come to mind.
    1. ADF DI (desktop integration): sorry, don't know enough about it to give a how to :-(
    2. POI (http://poi.apache.org/) : open source project to read and write excel file with java. Using POI you can open the .xsl file, read it's contents and display it as af:table. For this you need to read the xsl into a data structure (this can be a temporary db table or a list of POJOs) and build a data control out of it. This you can drop on a page as table.

  • Reading from a text file and displaying the contents with in a frame

    Hi All,
    I am trying to read some data from a text file and display it on a AWT Frame. The contents of the text file are as follows:
    I am writing a method to read the contents from a text file and store them into a string by using FileInputStream and InputStreamReader.
    Now I am dividing the string(which has the contents of the text file) into tokens using the StringTokenizer class. The method is as show below
    void ReadTextFile()
                        FileInputStream fis=new FileInputStream(new File("nieman.txt"));
                         InputStreamReader isr=new InputStreamReader(fis);
                         char[] buf=new char[1024];
                         fstr=new String(buf);
                         String Tokenizer st=new StringTokenizer(fstr,",");
         } //close of while loop
                    } //close of methodHere goes my problem: I am unable to display the values of pcode1,pname1,price1,sname1 when I am trying to access them from outside the ReadTextFile method as they are storing "null" values . I want to create a persistent string variable so that I can access the contents of the string variable from anywhere with in the java file. Please provide your comments for this problem as early as possible.
    Thanks in advance.

    If pcode1,pname1,price1,sname1 are global variables, which I assume they are, then simply put the word static in front of them. That way, any class in your file can access those values by simply using this notation:

  • I need to read data from a text file and display it in a datagrid.how can this be done..please help

    hey ppl
    i have a datagrid in my form.i need to read input(fields..sort of a database) from a text file and display its contents in the datagrid.
    how can this  be done.. and also after every few seconds reading event should be re executed.. and that the contents of the datagrid will keep changing as per the changes in the file...
    please help as this is urgent and important.. if possible please provide me with an example code as i am completely new to flex... 

    It's not possible to read from a file without using classes from the core API*. You'll have to get clarification from your instructor as to which classes are and are not allowed.
    *Unless you write a bunch of JNI code to replicate what the java.io classes are doing.

  • I have a VI and an attched .txt data file. Now I want to read the data from the .txt file and display it as an array in the front panel. But the result is not right. Any help?

    I have a VI and an attched .txt data file. Now I want to read the data from the .txt file and display it as an array in the front panel. But the result is not right. Any help?
    try2.txt ‏2 KB
    read_array.vi ‏21 KB

    The problem is in the delimiters in your text file. By default, Read From Spreadsheet File.vi expects a tab delimited file. You can specify a delimiter (like a space), but Read From Spreadsheet File.vi has a problem with repeated delimiters: if you specify a single space as a delimiter and Read From Spreadsheet File.vi finds two spaces back-to-back, it stops reading that line. Your file (as I got it from your earlier post) is delimited by 4 spaces.
    Here are some of your choices to fix your problem.
    1. Change the source file to a tab delimited file. Your VI will then run as is.
    2. Change the source file to be delimited by a single space (rather than 4), then wire a string constant containing one space to the delimiter input of Read From Spreadsheet File.vi.
    3. Wire a string constant containing 4 spaces to the delimiter input of Read From Spreadsheet File.vi. Then your text file will run as is.
    Depending on where your text file comes from (see more comments below), I'd vote for choice 1: a tab delimited text file. It's the most common text output of spreadsheet programs.
    Comments for choices 1 and 2: Where does the text file come from? Is it automatically generated or manually generated? Will it be generated multiple times or just once? If it's manually generated or generated just once, you can use any text editor to change 4 spaces to a tab or to a single space. Note: if you want to change it to a tab delimited file, you can't enter a tab directly into a box in the search & replace dialog of many programs like notepad, but you can do a cut and paste. Before you start your search and replace (just in the text window of the editor), press tab. A tab character will be entered. Press Shift-LeftArrow (not Backspace) to highlight the tab character. Press Ctrl-X to cut the tab character. Start your search and replace (Ctrl-H in notepad in Windows 2000). Click into the Find What box. Enter four spaces. Click into the Replace With box. Press Ctrl-V to paste the tab character. And another thing: older versions of notepad don't have search and replace. Use any editor or word processor that does.

    Else say how to create a new XML file through the code and how some content like Example "Hello World".

    You can create a text file as a file attachment (data object) using the doc.createDataObject and doc.setDataObjectContents:
    You can then export the file with the doc.exportDataObject method:
    This won't work with Reader if it hasn't been given the file attachment usage right with LiveCycle Reader Extensions.

  • Upload wsp file and configure webpart in Sharepoint 2013

    Hi All,
    I have a WSP file which has custom webpart built from VS 2013.
    Now I need to upload WSP file and add that webpart in the site I have created.
    I have gone to Site settings--> Web Designer Galleries --> Solutions and uploaded Solution.
    Then activated.
    But when I go to Site settings--> Web Designer Galleries--> Webparts and go to 'New' , I am not able to see that webpart!!!
    Regards, Shreyas R S

    I assume it is not a Sandbox solution and it a full trust solution. Try below:
    Remove that webpart
    On sharepoint server type
    path of file e.g. c:\132.wsp
    Then from central admin > systems > farm solutions > select the wsp and select deploy
    Once deployed it has reference in web.config which did not happened in your previous case.
    then you can follow same process of activating the solution and adding it to page

  • Upload csv file and insert into a table for user

    i want to create a Page on which, the User of my Application can upload a semicolon delimited file and the data of the file should automatically be stored in a table.
    I can upload the file and the file is then stored in the htmldb_application_files table.
    But I do not no how to parse the file....
    Can anyone help me or is there anyone who have done that before?
    Thank you,

    Here is what I did in a similar situation.
    Let the user download a csv file to use as an excel turnaround document.
    I check digit the primary key. They are not supposed to touch that column.
    They do their excel thing adding data in columns next to the ones they are updating. They now have the original and new data on the same row in the excel document. They save it on a share drive as a csv. A perl script wakes up and parses the csv. Verify's the check digit, checks that the old values still exist in the table... etc, and then does the update if all is well at the row level. The csv is replaced showing the success or failure of the update on each row.
    Probably lots of other ways to accomplish this but I have gotten years of use out of the script. The original csv can come out of almost any application. Mine come from apex, discoverer and some excel queries.
