Compare any 2 files through java

hi
i m newbie in java. can anyone tel me as to how we should compare contents any 2 files(xml,text) any file any JAVA.
i have to compare contents and generate a report about mismatch in those 2 files .
plz help me ASAP

Hi,
What u can do is use 2 FileReader's (one for each file). Loop thru' each character in each file and compare them (compare 1st char of 1st file with 1st char of 2nd file...2nd char of 1st file with 2nd char of 2nd file and so on). If they are not equal store the position in an array (pos will be same on both the files). Now display the result highlighting the position u stored in the array. (u have to also check for diff in file size).
Check out http://java.sun.com/docs/books/tutorial/essential/io/filestreams.html for starters.

Error while running executable file through java in WinNT

I would like to run an executable file with Java.
- If I try with notepad or paint, i.e. Windows Applications,
  I have no problem.
- I also can run Non-Windows-Own Applications, except one.
  I get an error message, if I want to run this program through Java.
I have tried following commands to run an executable file.
Runtime.getRuntime().exec("cmd.exe /c "+command);
Runtime.getRuntime().exec("cmd.exe /c start "+command);
Runtime.getRuntime().exec("cmd.exe /c start /wait "+command);
Runtime.getRuntime().exec("cmd.exe /k start "+command);
command : the path to the executable file
I can run the application directly, if I click the icon on desktop,
but not through Java.
here is the error message I get
screenshot : http://www.aykut.de/error_message.jpg
Text : "Security Check failure"
        The Logon System has been tampered with.
        The Administrator will need to re-install.
my Idea :
The application is "old".
I think it was written for Win 3.1.
Therefore I don't know if there is any other
possibilty to run a "DOS Exe File" through Java.

I have just figured out how it works,
if somebody else here in forum have this problem,
here is the solution :
String path = "F:\...\...\Application.exe";
String envDir = path.substring(0, path.lastIndexOf("\\"));
String[] command = {"cmd.exe", "/c", "start", "/wait", "/D"+envDir, path};
Process process = Runtime.getRuntime().exec(command);
"start /Dpath" => path: environment directory F:\...\...\
"start /wait" => wait until Application.exe terminates
if you use Win95 or Win98 use command.com instead of cmd.exe

How to get the source code of an HTML page in Text file Through java?

How to get the source code of an HTML page in Text file Through java?
I am coding an application.one module of that application is given below:
The first part of the application is to connect our application to the existing HTML form.
This module would make a connection with the HTML page. The HTML page contains the coding for the Form with various elements. The form may be a simple form with one or two fields or a complex one like the form for registering for a new Bank Account or new email account.
The module will first connect through the HTML page and will fetch the HTML code into a Text File so that the code can be further processed.
Could any body provide coding hint for that

You're welcome. How about awarding them duke stars?

Why not just use the unix "diff" command?
You can always install cygwin and use diff from there.

How to compile dunamically genrated java files through java program?

Hi, I have a requirement where i generate java files from WSDL dynamically using wsdl2java jaxbri. I need to compile these files dynamically on the fly and jar it. Everything should happen through java program. Bcos everything is dynamic here, no information is known (like dir, file names ...) until the runtime. Everything is user fed.
the directories may contain other directories with java files. its recursive
i tried com.sun.tools.javac.Main.. but either its not scaling to my needs or i donno how to wok with this.
is there any option to compile the java files as they are created thru JAXBRI (wsdl2java)?
any help is appreciated..
-s

my requirement is :
i create java files from wsdl2java (axis).. i need to compile all the java files.. directories with in the directories (recursive)...
as bcos the the java files have inter-dependencies they have to be compiled as a bunch something like (java *.java). I donno how to do this in javac.Main tool
Once all these files are compiled i need to create a jar out of them
Any help is appreciated!

Invoking batch file through java pgm

hi
i want to invoke run.bat file from java pgm, i have written following code
String[] cmd = new String[4];
          cmd[0] = "cmd.exe";
          cmd[1] = "/C";
          cmd[2] = "start";
          cmd[3] = "run.bat";
          Process p=Runtime.getRuntime().exec(cmd);
          p.waitFor();
It's working without error but it is not giving any output.
plz guide
Also give me syntax to run commands of cmd through java pgm.
Thanks

Hi,
What type of output you expected. If you want to cmd output from process then use following code
String[] cmd = new String[4];
cmd[0] = "cmd.exe";
cmd[1] = "/C";
cmd[2] = "start";
cmd[3] = "run.bat";
Process p=Runtime.getRuntime().exec(cmd);
BufferedReader in = new BufferedReader(new InputStreamReader(p.getInputStream()));
String inputLine;
while ((inputLine = in.readLine()) != null)
     pingResult += inputLine;
in.close();
p.waitFor();Edited by: sagar_birari on Mar 26, 2008 4:47 AM

Writing into a jar file through Java program

Is there a way to get a file from a jar (for ex. a properties file) make changes to it on the fly and write the same file back to the jar through a Java program?

I cannnot give u exact code as i am bit busy..but i am giving close to exact
below is code for reading contents of jar file
import java.io.*;
import java.util.jar.*;
public class JarRead {
public static void main (String args[])
throws IOException {
if (args.length != 2) {
System.out.println(
"Please provide a JAR filename and file to read");
System.exit(-1);
JarFile jarFile = new JarFile(args[0]);
JarEntry entry = jarFile.getJarEntry(args[1]);
InputStream input = jarFile.getInputStream(entry);
process(input);
jarFile.close();
private static void process(InputStream input)
throws IOException {
InputStreamReader isr =
new InputStreamReader(input);
BufferedReader reader = new BufferedReader(isr);
String line;
while ((line = reader.readLine()) != null) {
System.out.println(line);
reader.close();
now here say u have test.jar which contains test.txt (file)
then
java JarRead test.jar test.txt
will print content of text.txt
now in ur case u write content of each file in some other file modify it there and then create a jar file from those files using jaroutput stream .....
this may not be all clear ..but what to do..bit busy...u are welcomed to make changes in above stratergy....n queries if any after using above stratergy and/or your great brain...

Accessing XML files through java

Can any one explain me the easiest way of accessing XML files from Java.

Hi,
If you want to only access the XML file, use the SAX parser It will be very easy to handle and identify the element and value.
else if u want to change the XML value also, then better go with DOM, Which has very good flexiblity.
use according to the need, let me know if any help is required......
With Cheers
