Hi All,
I have developed an applet-servlet application in Jbuilder9. When I run my applet from JBuilder it runs fine.
So, this is what i did...
I copied my package class file to
D:\JBuilder9\thirdparty\jakarta-tomcat-4.1.24-LE-jdk14\webapps\examples\WEB-INF\classes

and my LoginScreen.html file in
D:\JBuilder9\thirdparty\jakarta-tomcat-4.1.24-LE-jdk14\webapps\ROOT
LoginScreen.html
----------------
<html>
<head>
<title>
</title>
</head>
<body>
<applet
codebase = "."
archive = "ScanStation.jar"
code = "scanstation.LoginScreen.class"
name = "ScanStation"
width = "350"
height = "200"
hspace = "0"
vspace = "0"
align = "middle"
>
</applet>
</body>
</html>
When i run this from Internet Explorer as....
http://10.120.123.15:8080/LoginScreen.html
it displays the Login screen that i created....But when i hit my button to submit it's not displaying anything....
In my Java Console....I am getting the following error.

I don't suppose you are trying to open a socket connection or database connection to a server other than your webserver? Applets can only open connections to the server they were downloaded from. If that's not the problem you may have to show the relevant code.
