ConnectException when using Tomcat 4.1

Question

Hi,
I'm trying to run my web application with Tomcat 4.1 (until now I worked with Tomcat 3.2, and didn't have problems).
In my application I have an applet that reads from a file (the file is located on the web server.)
When I try to do it (using Url.openStream()) I get:
java.net.ConnectException: Connection refused.
I guess I have to configure some kind of permissions in the tomcat configuration files or something like that, but I didn't find anything.
(In my Java policy tool I made sure to give java.security.AllPermission, but I'm not sure that it's connected).
Can you please help me?...
Thanks,
Efrat

The code the I use is:
// With a URL now available, try to esatablish a read
// mechanism and read in the file as a series of String lines
try
InputStream is = sourceUrl.openStream();
InputStreamReader isr = new InputStreamReader (is);
BufferedReader d = new BufferedReader (isr);
return (readLines(d));
catch (java.io.FileNotFoundException iof)
Debug.err ("FileNotFoundException: " + iof);
JOptionPane.showMessageDialog(applet, "Problems with web server were discovered. Device image will not be shown.\nPlease check server and device status and correct, then try to login again.");
return null;
catch (IOException e)
Debug.err ("exception in fetchLines: " + e);
e.printStackTrace();
return null;
The exception that I get is:
exception in fetchLines: java.net.ConnectException: Connection refused: connect
java.net.ConnectException: Connection refused: connect

Thanks a lot,
