You can do it in Java too. Use the URL class to make the connection to the URL, pass the data.
Take the response in a String (StringBuffer) and then parse it.

You can do that in Java too, and read the links given by Garbage, if you want to do it in PHP means, you can.

Check this code out:
Code: 
import java.io.*;
 
public class FileOps {
public static void main(String args[])
{
    File file = new File(args[0]);
    try
    {
        BufferedReader in = new BufferedReader(new FileReader(file));
        String s;
        s = in.readLine();
        while(s!=null)
        {
            System.out.println("Read " + s);
            s = in.readLine();
        }
        in.close();
    }
    catch(FileNotFoundException e1)
    {
        System.err.println("File Not Found" + file);
    }
    catch(IOException e2)
    {
        e2.printStackTrace();
    }
}
}
Now I'm getting this error "Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 0
at FileOps.main(FileOps.java:13)
Java Result: 1
"
What's the solution? :confused:

create a new func and call it from main,then it will solve.

the o/p im getting is 21, 41, 61, when i click...i think there is a logical error in the code. because when i am changing the value of the for loop

for(i=0;i<=20000;i=i+10000)

i am getting odd values...do check it out for that...

If you are a beginner in javascript...
do check out this book its really nice:John Wiley & Sons - JavaScript in 10 Steps or Less

hope this helps....

Thats because the setTimeout() returns the ID, which can be used for clearTimeout() function, and not the value which you want to setup.
Please check the code which I provided in above post.

Javascript doesnt comes under Java. So please stop posting Scripting queries from now on. If you wish, just start a new thread for that and post your questions there.

You probably did set PATH=<something something>

Instead do set PATH=%PATH%;<something something>

No, Not working
After setting it as path, when I try to use cmd commands like
ping xxx.xxx.xxx.xxx
it says
'ping' is not recognized as internal command
Click to expand...

There's a small correction. It actually is:

Code: 
set PATH = %PATH%;"C:\Program Files\Java\jdk1.6.0_20\bin"

And as far as your ping not working: it maybe because you haven't done this in a new cmd window. Close your current window, do the set PATH thing again in a new window and then try the ping command.

And if still does not work, then tell me the outputs of the following command in a new cmd window, before and after setting the PATH:

Code: 
echo %PATH%

Oh Yes!!!!!!!!!
Finally I figured It Out, Thanks for helping.

Instead of %PATH% I wrote %systemroot%\system32;C:\Program Files\Java\jdk1.6.0_20\bin

and now all is working fine.
