Servlets let you communicate with with the Server to upload, store & retrieve files, process cookies, respond to web page forms, and otherwise free you from some of the constraints placed on stand alone applets.

cooperates with version 1.1 of the Java Development Kit (JDK) ... Thanks, Jef!"

The two clients, and the Web Server Administration Applet as they appear on my Windows95 machine.
It's neat that I could develop ( modify ) these on my Windows machine, but lacking a server on the internet severely constrains chatting...
| $ cd C:\Java\Servlets\Server\bin
| $ .\httpd -javahome C:\Java\sdkBorland\java -verbose
then to start the Admin applet I click on the MiSE icon and go to a bookmarked URL which is :
http://localhost:9090/index.html
and that's it ! The Server and Admin are both up and running.
My directory structure:
C:\Java ( all my Java )
C:\Java\sdkBorland ( JBuilder JDK 1.1 Compiler / SDK ( $99 ) )
C:\Java\Servlets ( my Servlets )
C:\Java\Sevelets\Server ( Sun's Java Web Server directory ( Free 30 day trial version ) )
C:\Java\Servlets\Server\bin\httpd.exe ( the Server program )
C:\Java\Servlets\Server\index.html ( Admin applet, aka http://localhost:9090/index.html )

Servlet facilitated features I'd like to have are "Save / Retrieve / Send" functions for my "Build a Snowman" applet which is a feature I've had ( commercial and noncommercial ) requests to add.
