How to display my text file in swing

hi all,
i have a screen where user enters a batch no. and number.
when user presses a button i should get a list displayed on my sreen.
how to do this...and how to call function that generates the list in my actionlistener..please help me....

You need to post some code in code tags. What you are asking is very easy to do yet it sounds as though you are flustered. Step back and learn each and every thing you need to do (plan) before you attempt anything in Java, trying to find out what API you need in the middle of a project is a sign of looming disaster.
Your button needs and actionlistener and an actionPerformed method; if you have only a foggy idea what this is you need to look them up. Also, your list can be displayed in a JTextPane, JEditorPane, JTextArea, JList (?), or JTable. I suggest all these since I did not see specific requiorments posted. When dealing with any of these pay atention to the model (contains the data FOR the view object). JTextArea is the lightest of these and probably the least confusing, be sure to put it in a JScrollPane if you want to, uh, scroll the list.

How to display a text file in a html page?

I have written a servlet that executes a batch file whose output is saved to a txt file. I am attempting to display content of the text file as a html page from the servlet but am struggling I have attempted to read the file and output it as shown below but it is not displaying the correct data
Appreciate some help
Thanks in advance
Amjad
Runtime r = Runtime.getRuntime();
Process p = r.exec("C:\\Condor\\test\\QueStatus.bat");
PrintWriter out;
String title = "Que Status";
response.setContentType("text/html");
out = response.getWriter();
FileReader fr = new FileReader ("C:\\Condor\\test\\output.txt");
for (int chr = fr.read(); chr != -1; chr = fr.read()){
out.print(chr);
}

Couple of things. First you should search the forums for how to properly exec a dos batch file. There are some problems you may run into especially with io. I suspect you may not actually be running that batch file at all.
I would test outputing a text file separately from execing the batch file.
Here is some code so you don't have to output 1 char at a time. Setting the content length and closing the output stream might help.
File downloadFile = new File("c:\\blah\\blah\\blah");
response.setContentLength((int)downloadFile.length());
response.setContentType("text/html");
ServletOutputStream out = response.getOutputStream();
FileInputStream fis = new FileInputStream(downloadFile);
byte[] buffer = new byte[1024];
int bytesRead;
while ((bytesRead = fis.read(buffer)) != -1) {
out.write(buffer, 0, bytesRead);
fis.close();
out.close();

I have reviewed some files and it is not helpful

How to attach a text file as an attachment to email message?

Hello Everybody,
I have a .csv file, in which details about emp-id, emp-name, e-expenses for Reimbursement and email address are stored.
My application reads this .csv file, and sends a mail to each employee with his id, salary details in text format. (by changing content type to "text/plain") The code is working fine. But,
My problem is:
The message is sent as message body to the end user.
The end user / the person who receives this mail will not be a technical person. So,
1) If he trys to take a print out of this e-mail, He get only half of it.(as no. of colums will be more than paper size).
2) I am finding alignment problem. IF employee name is too big, other columns will shift to right and data will not be exactly under column header. (it is going in zig zag way)
So, I thought sending text file with all the details as an attachment might do well.
But, I don't know how to attach a text file to email-message body.
code
try
 { String s1="";
 File f1 = new File(the path);
 FileInputStream fstream = new FileInputStream(f1); //new
 BufferedReader br = new BufferedReader(new InputStreamReader(fstream));
 int count=0;

 count++;
 //out.println("within while loop "+count);

How to convert a text file content to String in JSP?

Hi,
I need to read the content of a text file and convert it into String and display it on to a JSP file.
But the codings below don't work. Please advise me on how can i display the text file content.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
File adCheck = new File("list.txt");
fis = new FileInputStream(adCheck);
int Length = adCheck.length();
byte arr[] = new byte[Length];
int dataRead = 0;
int totalData = 0;
while(totalData <Length)
 dataRead = fis.read(arr,totalData,Length);
 totalData += dataRead;
String Content = new String(arr);//byte array converted to String
arr = null;

 InputStreamReader in=new InputStreamReader(fis);
 StringWriter out=new StringWriter();
 char[] buffer=new char[8192];
 int sizeRead;
 while ( ( sizeRead=in.read(buffer, 0, 8192) ) != -1 )
 out.write(buffer, 0, sizeRead);
 String content=out.toString();

How to display a .txt file?

i would like to ask if JAVA can open and display a text file by issuing a command from my application
is it possible to do it without using a JEditorPane?
something else too, how can i set the background for my application to be a .jpg image?
i searched and realised there is no such method as
setBackground(String url)

Try this... Note you need to add adequate exception trapping and detect special cases like the file being larger than the allocatable size of a character array (in which case you can't convert the file to a string and will need to 'display' the file in sections)...
import java.io.*;
public class LoadFile {
public static String fileToString(File file) throws IOException {
 char[] fileContents = new char[(int) file.length()];
 FileReader fr = new FileReader(file);
 if(fr.read(fileContents) != fileContents.length) {
 System.err.println("There was a problem reading the file contents");
 return null;
 else return new String(fileContents);
public static void main(String[] args) throws IOException {
 if(args.length != 1) System.err.println("Usage:\n\tjava LoadFile <filename>");
 else {
 File f = new File(args[0]);
 try {
 String s = fileToString(f);
 System.out.println(s);
 } catch(IOException e) {
 System.err.println("Whoops");
}Hope that helps...

How to upload a text file from a shared folder and provide an o/p

how to upload a text file from a shared folder and provide an o/p containing the details in each order in the text file

Hi,
Use GUI_UPLOAD to upload a text file from a shared folder.
Use GUI_DOWNLOAD to download data in a file on the presentation server or use OPEN DATASET, TRANSFER and CLOSE DATASET statements to download data to the application server.
Now, I hope the code for data fetching, if required, is already present in the report.
Reward points if the answer is helpful.

How to convert a text file in lower case to upper case?

I've a beginner in java world and I just come through the tutorial in http://java.sun.com/docs/books/tutorial/essential/io/filestreams.html showing how to copy a text file:
import java.io.*;
public class Copy {
public static void main(String[] args) throws IOException {
File inputFile = new File("farrago.txt");
File outputFile = new File("outagain.txt");
FileReader in = new FileReader(inputFile);
FileWriter out = new FileWriter(outputFile);
int c;
while ((c = in.read()) != -1)
out.write(c);
in.close();
out.close();
And I would like to ask how to covert all lower case letters in input file to upper case letter in output file at the same time of copying.
I guess it'll be using Character.toUpperCase(c), but I don't know how to do it actually.
Any help would be much appreciated.

Hope this helps
import java.io.*;
public class Copy {
public static void main(String[] args) throws IOException {
File inputFile = new File("farrago.txt");
File outputFile = new File("outagain.txt");
FileReader in = new FileReader(inputFile);

BufferedReader buff = new BufferedReader(in);
String c;
while ((c = buff.readLine()) != null)
out.write(c.toUpperCase());

out.close();

How to send a text file to a printer?

Hi, I'm in dark on how to send a text file to a printer through Java Stored Procedure.
Here are what I tried so far (OS: win 2000, Oracle: 817 or 9i2):
1, Enable DOS command in Java Stored Proc. and try to send PRINT command there:
public static String Run(String Command){
try{
Runtime.getRuntime().exec(Command);
System.out.println("Command: " + Command);
return("0");
catch (Exception e){
System.out.println("Error running command: " + Command +
"\n" + e.getMessage());
return(e.getMessage());
public static void main(String args[]){
if (args.length == 1)
Run("print /D:\\\\enterprise\\john " + args[0]);
else System.out.println("Usage: java OSCommand filename");
PL/SQL wrapper:
CREATE OR REPLACE FUNCTION OSCommand_Run(p1 IN VARCHAR2) RETURN VARCHAR2 AUTHID CURRENT_USER AS LANGUAGE JAVA NAME 'OSCommand.Run(java.lang.String) return java.lang.String';
SQL command:
//print /D:\\machine\printer test.txt
I loaded the Java Stored Procedure into SYSDBS account, it failed silently, even though piece of code works fine in external JVM.
2, Use filePrinter:
public static String print(String printString) {
try{
String printerUNC = "\\\\machine\\printer";
FileWriter fw = new FileWriter(printerUNC);
PrintWriter pw = new PrintWriter(fw);
pw.println(printString);
fw.close();
return "OK";
}catch(Exception e){
e.printStackTrace();
return "Exception: " + e.getMessage();
public static void main(String[] args) {
try{
String printerUNC = "\\\\machine\\printer";
String printString = "Hello World";
FileWriter fw = new FileWriter(printerUNC);
PrintWriter pw = new PrintWriter(fw);
pw.println(printString);
fw.close();
}catch(Exception e){e.printStackTrace();}
I loaded it into SYSDBS too, and tried with this:
SQL> select MY_PRINT.PRINT('HELLO from Oracle') from dual;
MY_PRINT.PRINT('HELLOFROMORACLE')
Exception: No such file or directory
SQL> show user
USER is "SYS"
It works in external JVM too.
What's wrong with this?
Thanks for any help in advance,
Charles

Avi:
Thanks for your response!
I put the java code in SYS, 'cause I assume that account has max privilege. If the test is successful, I will move that to some user schema and then to deal with those privilege settings... But I'm unlucky.
I checked Ask Tom, this is what I got from http://asktom.oracle.com/pls/ask/f?p=4950:8:1619723::NO::F4950_P8_DISPLAYID,F4950_P8_CRITERIA:38012348052,%7Bprinter%7D:
... Print file from PL/SQL ...
If you are using Oracle8i, release 8.1 -- much can be done with Java. java
would be able to print directly from the server.
Looks like using Java to print out file is better than PL/SQL. But there's no more hint there! And, no new question can be asked there today either...
I'm wondering whether we can create a socket to a printer and send the characters there directly... Anyone has experience on this?
Thanks for all the help in advance,
Charles

How to create a text file or XML file and add content through code into it...

Hi Everyone,
How to create a text file and add content through the code to the text file eform javascript ......orelse can we create a text file in life cycle designer...
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:
http://livedocs.adobe.com/acrobat_sdk/9.1/Acrobat9_1_HTMLHelp/JS_API_AcroJS.88.450.html
http://livedocs.adobe.com/acrobat_sdk/9.1/Acrobat9_1_HTMLHelp/JS_API_AcroJS.88.528.html
You can then export the file with the doc.exportDataObject method:
http://livedocs.adobe.com/acrobat_sdk/9.1/Acrobat9_1_HTMLHelp/JS_API_AcroJS.88.463.html
This won't work with Reader if it hasn't been given the file attachment usage right with LiveCycle Reader Extensions.

How to read a text file using Java

         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.
