Hi,
I am running Ubuntu in my machine and I tried this code:
import java.io.InputStream;
import java.io.IOException;
import java.applet.Applet;
import java.awt.*;
public class execute extends Applet{
String output="";
public void init(){
try {
// Execute command
String command = "ls";
Process child = Runtime.getRuntime().exec(command);
// Get the input stream and read from it
InputStream in = child.getInputStream();
int c= in.read();
while ((c = in.read()) != -1) {
output =output+((char)c);
}
in.close();
}
catch (IOException e) {
}
System.out.println(output);
}
public void paint(Graphics g){
g.drawString(output,60,100);
}
}And then wrote this html file and saved it in the same directory:
<html>
<head><title>Applet</title>
<body>
<applet code="execute.class",height="200" width="200">
</body>
</html>What I'm trying to do here is to run the ls shell command in an applet and display the results.
The code compiles with no errors. But when I open the html file in the browser, I just get a gray square.
Is this because of security issues that I don't get anything? Or is it because of an error in the code? Or is it the browser that is the problem?
Please help,
Thanks in advance.
