applet not running

Hi there,

I am having problem with my java applet code. I have the following file.

import java.applet.*;
import java.awt.*;

class getValue
int count=0;
int[] y = new int[1560];

public void getx() throws IOException
FileInputStream LogFile = new FileInputStrea ("Record.log");
DataInputStream in = new DataInputStream(LogFile);
while (in.available() !=0)
y[count] = Integer.parseInt(in.readLine());

public class FirstLine extends Applet
public void paint(Graphics g)
getValue x;
x = new getValue();
catch (IOException e)
g.drawString("File not found", 100, 100);
g.drawString("Mobitel", 100, 100);
for (int i=0; i < 383; i++)
g.drawLine(i, 300-x.y[i], i, 300-x.y[i+1]);

And below is my html code of the file named FirstLine.html

<applet code=FirstLine.class width=400 height=300>

The problem is that I can sucessfully run the applet in appletviewer, but failed to run in web browser. I am using Internet Explorer.

Can anyone help me to correct my code?

How about opening the java console and seeing what the error is? I will bet it is a security exception. Unsigned applets can't open files on the client computer.

Try using the below html lines and check out that class file and html files are in the same directory.

<applet code="FirstLine.class" width=400 height=300></applet>
I agree. Here's the link:
