Applet and IIS

Hi there!

I have an applet calss that works fine with my html page. Now, I want this thing to work with IIS. I coppied the files to my web site home directory on my windows xp pro machine, which IIS 5.1 is installed. It works fine. Then I the files coppied to another machine, windows 2000 server with IIS 5.0 installed. It doesn't work. I go to Internet Explorer and type "http://localhost/myfile.html", then i got the message saying that "Connection refused: connect". I don't know why it doesn't work. Can anyone give me some idea or advise?

Thanks,
Roda

Is applet or the browser is giving you the error message? If it is the applet, what does the applet do?

Yes, the applet is giving me an error message saying that "Connection refused: connect". My applet class is to read data from files and build graph.

Below is my applet code.

import java.io.*;
import java.net.*;
import java.awt.*;
import java.applet.Applet;

public class CallsGraph extends Applet{

public void paint(Graphics g){
setBackground(Color.white);
String ncalls = "";
int minute = 0;
String hour = "";
int count = 100;
int inthour;
int j = 0;
int y1 = 0;
int y2 = 0;
int y = 0;
try{
URL documentBase = getDocumentBase();
String path = documentBase.getPath();
path = path.substring(0, path.lastIndexOf("/"));

URL logfileURL1 = new URL(documentBase.getProtocol(), documentBase.getHost(), path + "/Total.log");
URLConnection connection1 = logfileURL1.openConnection();
InputStreamReader isr1 = new InputStreamReader(connection1.getInputStream());
BufferedReader br1 = new BufferedReader(isr1);
String lineRead1 = "";
g.setColor(Color.green);
while ((lineRead1 = br1.readLine()) != null){
ncalls = lineRead1.substring(7, 10);
y = Integer.parseInt(ncalls);
g.drawLine(count, 320-y, count, 320);
count++;
}
count = 100;

URL logfileURL2 = new URL(documentBase.getProtocol(), documentBase.getHost(), path + "/Record.log");
URLConnection connection2 = logfileURL2.openConnection();
InputStreamReader isr2 = new InputStreamReader(connection2.getInputStream());
BufferedReader br2 = new BufferedReader(isr2);
String lineRead2 = "";
while ((lineRead2 = br2.readLine()) != null){
ncalls = lineRead2.substring(7, 10);
minute = Integer.parseInt(lineRead2.substring(3, 5));
if (minute == 0)
{
hour = lineRead2.substring(0, 2);
inthour = Integer.parseInt(hour);
if (inthour%2 == 0)
{
hour = Integer.toString(inthour);
g.setColor(Color.black);
g.drawString(hour, count-3, 340);
for (int i = 20; i <= 320; i+=5)
{
g.drawString(".", count, i);
}
}
}
y = Integer.parseInt(ncalls);
if (count==100)
{
y1 = y;
}
else if (y2 > y1)
{
if ((y > y1) && (y > y2) )
{
y1 = y2;
}
else if ((y > y1) && (y < y2))
{
y1 = y;
}
}
else if (y1 > y2)
{
if ((y > y2) && (y < y1))
{
y1 = y;
}
else if ((y < y1) && (y < y2))
{
y1 = y2;
}
}
g.setColor(Color.red);
g.drawLine(count, 320-y, count, 320-y1);
y2 = y1;
y1 = y;
count++;
}
g.setColor(Color.black);
for (int i=20; i<320; i+=20){
ncalls = Integer.toString(i);
g.drawString(ncalls,70, 322-i);
g.drawString(". . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .", 100, 320-i);
}
g.drawLine(100, 20, 100, 320);
g.drawLine(100, 320, 485, 320);
g.drawString(">", 485, 325);
g.setColor(Color.green);
g.drawString("All Operators",585, 100);
g.setColor(Color.red);
g.drawString("Mobitel (012)", 585, 130);
}catch(MalformedURLException murle){
g.drawString(murle.getMessage(), 100, 100);
getAppletContext().showStatus(murle.getMessage());
}catch(IOException ioe){
g.drawString(ioe.getMessage(), 100, 100);
getAppletContext().showStatus(ioe.getMessage());

}
}
}

Thanks anyway.

The only thing I can think of is that this URL:

does not match the original. Is IIS running on port 80 (standard HTTP port)?

No, my IIS is running on port 8080. I failed to make it run on port 80. The error message is "Address is already in use". If the problem is with the port, how can I make it run on port 8080? Or, how can I make my IIS run on port 80?

Thanks,

Roda

If your port is at 8080, then your url should be like this "http://localhost:8080/myfile.html". Without the port explicitly specified in URL, it defaults to 80.

Yes, I typed this url, "http://localhost:8080/myfile.html", in the address box. The page was loaded, but the applet doesn't work. It shows the message saying that "Connection refused: connect".

Thanks anyway.

Now, I have found that my code is working with standard http port, 80. But I have another service running on that port. That's why I use port 8080 instead. So, how can I make it work with port 8080? Does this relate to the following line of code?

If it does, can you correct the code for me? I don't know how to correct it. I am new to java.

Thanks in advance.

If you look at the documentation for java.net.URL, you will see that it has a number of constructors. You are using the 3-String constructor (String protocol, String host, String file). There is another one that takes 3 strings and a port number. You could also create a URL using a single String object and just concatenate all the parts together (i.e. protocol+host+port+path+file.

Yes, your advice is really helpfull. I looked at the documentation and changed my code

From:

To:

It is now working fine with port 8080. So, my problem is fixed.

I appreciate all of your help very much, Joe Ess and meimei li.

Thanks alot.
