    Subject: Does netscape browser allow Java applet to read URL?

Helper,
I have to two questions:
1) My applet trys to read url file. With appletviewer it works fine but not
with
netscape browser. Is there any way I can work around not opening a socket?
2) It that any way to the URL is valid in Java? I have following code to check
the URL is valid, but it is not working right.

Thanks a lot,

public boolean URLexist(String urlstr)
{
boolean flag = false;
if (urlstr != null)
{
try {
URL url = new URL(urlstr);
DataInputStream stream = null;
stream = new DataInputStream(url.openStream());
flag = true;

//try {
//url.openConnection().getContent();
//flag = true;
//}
}
catch (IOException e)
{
Alert.runAlertInternally(Alert.warningImage(),urlstr,
"is not exist","OK",null,null);
flag = false;
}
}
return flag;
}
