Three years ago, I got a fancy for OS/2. This year, I purchased Warp Connect. Everything seemed OK. I downloaded Java Development Kit (JDK) 1.0.2 for OS/2, Netscape 2.02 for OS/2, and some lecture notes on Java. You can imagine my frustration when I realized that I couldn't run a network applet connecting to a host, even if the host had granted access, because Netscape wouldn'
t let me do so for security reasons. I believe security should be the host's problem, as in Unix, not the browser's problem. Are Java applets for thumbling ducks and Push Me buttons only?

Actually, the current security model does l
et applets communicate with the host on which they originated. Theoretically, you can use a socket connection for this purpose, but some firewalls block those connections. I got around this problem in one of my applets by URL-encoding the data and sending it back on the HTTP connection. A Perl script running on the host receives the data. Programming books on Java and HTML explain this in more detail and usually include some sample code. --Tom Halfhill, senior editor
