How to print a text file using Java

How can I print a text file using Java without converting the output to an image format. Is there anyway I can send the characters in the text file as it is for a print job? I did get a listing doing this ... but that converted the text to an image format before printing....
THanks,.

Hi I had to write a print api from scratch, and I did not convert the output to image. Go and read up on the following code. I know there is a Tutorial on Sun about the differant sections of the snippet.
private void printReport()
     Frame tempFrame = new Frame(getName());
     PrintJob printerJob = Toolkit.getDefaultToolkit().getPrintJob(tempFrame, "Liesltext", null);
     Graphics g = printerJob.getGraphics();
                //I wrote the method below for calculations
     printBasics(g);
     g.dispose();
     printerJob.end();
}This alone wont print it you have to do all the calculations in the printBasics method. And as I said I wrote this from scratch and all I did was research first the tutorial and the white papers

How to convert a HTML files into a text file using Java

Hi guys...!
I was wondering if there is a way to convert a HTML file into a text file using java programing language. Likewise I would also like to know if there is a way to convert any type of file (excel, power point, and word) into text using java.
By the way, I really appreciated the help that you guys gave me on my previous topic on how to extract tests from a pdf file.
Thank you....

HTML files are already text files. What do you mean you want to convert them?
I think if you search the web, you can find things for converting those MS Office files to text (or extracting text from them, as I assume you mean).

How to read a text file using Java

Guys,
Good day!
Please help me how to read a text file using Java and create/convert that text file into XML.
Thanks and God Bless.

     public void fileRead(){
             File aFile =new File("myFile.txt");
         BufferedReader input = null;
         try {
           input = new BufferedReader( new FileReader(aFile) );
           String line = null;
           while (( line = input.readLine()) != null){
         catch (FileNotFoundException ex) {
           ex.printStackTrace();
         catch (IOException ex){
           ex.printStackTrace();
     }This code is to read a text file. But there is no such thing that will convert your text file to xml file. You have to have a defined XML format. Then you can read your data from text files and insert them inside your xml text. Or you may like to read xml tags from text files and insert your own data. The file format of .txt and .xml is far too different.

Read Text file using Java Script

Hi,
I am trying to read a text file using Java Script within the webroot of MII as .HTML file. I have provided the path as below but where I am not able to open the file. Any clue to provide the relative path or any changes required on the below path ?
var FileOpener = new ActiveXObject("Scripting.FileSystemObject");
var FilePointer = FileOpener.OpenTextFile("E:\\usr\\sap\\MID\\J00\\j2ee\\cluster\\apps\\sap.com\\xapps~xmii~ear\\servlet_jsp\\XMII\\root\\CM\\OCTAL\\TestTV\\Test.txt", 1, true);
FileContents = FilePointer.ReadAll(); // we can use FilePointer.ReadAll() to read all the lines
The Error Log shows as :
Path not found

Hi Mohamed,
I tried above code after importing JQuery Library through script Tag. It worked for me . Pls check.
Note : You can place Jquery1.xx.xx.js file in the same folder where you saved this IRPT/HTML file.
<HTML>
<HEAD>
<TITLE>Your Title Here</TITLE>
<SCRIPT type="text/javascript" src="jquery-1.9.1.js"></SCRIPT>
<script language="javascript">

$.get( "http://ldcimfb.wdf.sap.corp:50100/XMII/CM/Regression_15.0/CrossTab.txt", function( data ) {
$(".result").html(data);
alert(data);
// The file content is available in this variable "data"
</script>

Changing HTML to text file using java

Hi,
I am doing a project in which i have to read news articles from websites. I have tried XML but for that i need to know which tag has the article in it. Since i have to read from various websites so each site used different tags for different informations.
Is there anyway that i can change an HTML file into a text file using java. Maybe some command that removes all the HTML tags and gives just the information. Is there anything else that anyone would like to recommend?
Thanx
yafis

Maybe something like this:
import java.io.*;
import java.net.*;
import javax.swing.text.*;
import javax.swing.text.html.*;
class GetHTMLText
     public static void main(String[] args)
          throws Exception
          EditorKit kit = new HTMLEditorKit();
          Document doc = kit.createDefaultDocument();
          // The Document class does not yet handle charset's properly.
          doc.putProperty("IgnoreCharsetDirective", Boolean.TRUE);
          // Create a reader on the HTML content.
          Reader rd = getReader(args[0]);
          // Parse the HTML.
          kit.read(rd, doc, 0);
          // The HTML text is now stored in the document
          System.out.println( doc.getText(0, doc.getLength()) );
     // Returns a reader on the HTML data. If 'uri' begins
     // with "http:", it's treated as a URL; otherwise,
     // it's assumed to be a local filename.
     static Reader getReader(String uri)
          throws IOException
          // Retrieve from Internet.
          if (uri.startsWith("http:"))
               URLConnection conn = new URL(uri).openConnection();
               return new InputStreamReader(conn.getInputStream());
          // Retrieve from file.
          else
               return new FileReader(uri);

Since the word "TEXT" is formed of 4 letters, you would read the text file 4 bytes by four bytes. Wrong on two counts. First, the file may not be encoded 1 byte per character. It could be utf-16 in which case it would be two byte per character. Second, even if it were 1 byte per character, the string "Text" may not start on a 4 byte boundary.
Consider a FileInputStream object "fis" that points to your text file. use fis.read(byte[] array, int offset, int len) to read every four bytes. Convert the "TEXT" String into a byte array "TEXT".getBytes(), and yous the Arrays class to compare the equality of the read bytes with your "TEXT".getBytes()Wrong since it relies on my second point and will fail when fis.read(byte[] array, int offset, int len) does not read 4 bytes (as is no guaranteed to). Check the Javadoc. Also, the file may not be encoded with the default character encoding.
The problem is easily solved by reading a line at a time using a BufferedReader wrapping an InputStreamReader wrapping a FileInputStream and specifying the correct character encoding.

Trying to write data to a text file using java.io.File

I am trying to create a text file and write data to it by using java.io.File and . I am using JDeveloper 10.1.3.2.0. When I try run the program I get a java.lang.NullPointerException error. Here is the snippet of code that I believe is calling the class that's causing the problem:
String fpath = "/test.html";
FileOutputStream out = new FileOutputStream(fpath);
PrintStream pout = new PrintStream(out);
Do I need to add additional locations for source files or am I doing something wrong? Any suggestions would be appreciated.
Thank you.

This class contained some other functions i've deleted, but i think it still works.
That enables to create a log (.txt file) that you can fill line by line.
Each line start by the current system date. This class was used in swing application, but could work in a web app.

Can't read a text file using java

Hi All
I am trying to read a log file.
ProgramA keeps updating the log file, while my program ProgramB reads it.
For some readson my ProgramB is not able to read the last two lines in the log file. If I run the program in debug mode it is reading all the lines.
This is having me frustrated.
Please let me know if there is a way to read entire contents.
Here is how I am reading the files ( 2ways)
     private static String readFileAsString(String filePath)
    throws java.io.IOException{
        StringBuffer fileData = new StringBuffer(1000);
        FileReader fr = new FileReader(filePath);
        BufferedReader reader = new BufferedReader(fr);
        char[] buf = new char[1024];
        int numRead=0;
        while((numRead=reader.read(buf)) != -1){
            String readData = String.valueOf(buf, 0, numRead);
            fileData.append(readData);
            buf = new char[1024];
        reader.close();
        fr.close();
        return fileData.toString();
       * Fetch the entire contents of a text file, and return it in a String.
       * This style of implementation does not throw Exceptions to the caller.
       * @param aFile is a file which already exists and can be read.
       static public String readFileAsString(String filePath) {
         //...checks on aFile are elided
         StringBuffer contents = new StringBuffer();
         //declared here only to make visible to finally clause
         BufferedReader input = null;
         try {
           //use buffering, reading one line at a time
           //FileReader always assumes default encoding is OK!
           input = new BufferedReader( new FileReader(filePath) );
           String line = null; //not declared within while loop
           * readLine is a bit quirky :
           * it returns the content of a line MINUS the newline.
           * it returns null only for the END of the stream.
           * it returns an empty String if two newlines appear in a row.
           while (( line = input.readLine()) != null){
             contents.append(line);
             contents.append(System.getProperty("line.separator"));
         catch (FileNotFoundException ex) {
           ex.printStackTrace();
         catch (IOException ex){
           ex.printStackTrace();
         finally {
           try {
             if (input!= null) {
               //flush and close both "input" and its underlying FileReader
               input.close();
           catch (IOException ex) {
             ex.printStackTrace();
         return contents.toString();
       }

If you're using JDK 5 or later, you could use the Scanner class for input information. See below:
try {
               Scanner reader = new Scanner(new File("C:\\boot.ini"));
               StringBuilder sb = new StringBuilder();
               while (reader.hasNextLine()) {
                    sb.append(reader.nextLine());
                    sb.append(System.getProperty("line.separator"));
               System.out.println(sb.toString());
          } catch (FileNotFoundException e) {
               e.printStackTrace();
          }

Read text file using Java(streamTokenizer)

Hi, all,
I am lost when trying to read data from a text file to a Java prgram. The text file looks like the following:
106,62,2322,8159,1
106,62,3658,8333,1
106,62,4215,8334,2
Each number is seperated by "," and each line representing one row of data. I was thinking about using streamTokenizer to read the data into a multi-dimentional array. Since I am new to Java and just read something about the streamTokenizer from book, I would like to get some help from someone who is more experienced with that.
Thanks for your help!
Kevin

Hi Kevin,
try this:
import java.io.BufferedReader;
import java.io.FileReader;
import java.io.IOException;
import java.util.ArrayList;
import java.util.List;
import java.util.StringTokenizer;
public class Answer {
        public static void main(String[] args) {
        List data = new ArrayList();
        try {
            BufferedReader in = new BufferedReader(new FileReader("...your text file ..."));
            String line;
            // reading the file line by line
            while ((line = in.readLine()) != null) {
                // splitting the line into token
                StringTokenizer st = new StringTokenizer(line, ",");
                List row = new ArrayList();
                while (st.hasMoreTokens()) {
                    row.add(new Integer(st.nextToken()));
                data.add(row); // adding the row of data
            in.close();
        } catch (IOException e) {
            e.printStackTrace();
        // test result
        System.out.println(data);
}I don't like to use arrays, because when I start reading the file, I don't know yet, how many rows of data it is containing. Therefore a java.util.List is much more convenient (you don't have to initialize). Your result is now a java.util.List containing elements of java.util.List containig elements of Integer.

Inserting line in a Text file using java

Hi,
I am working on a project in which the some data is required to be stored in a text file. I have lines of data in the file and I read 1 line at a time. So now I need to insert some lines of text in between. How to do this ??
Now i'm using a temporary file and then after creating the data I replace the original file with the new one. But want to know is there any better way to do that same..?!?!

Ok.. If I maintain a data in XML format, is it
possible to insert a node. I'm using Xerces and DOM
api for handling xml data.
As a file, XML is just a text file so you insert as you would any file.
Once parsed to a DOM model then sure you can insert nodes. Just look at the Javadoc for XML Document, Element, Node etc.
