Internet Programming 2 - Course: Server-side with Java Servlets
The goal of the Internet Programming 2 - course was to learn HTTP server-side programming. I chose to use Java servlets with Apache Tomcat as a servlet container/engine.
Here you can view my solutions of the course assignments.
About this Course
Since cheap Web hosting for servlets are more rare
than for example cheap PHP hosting(which I have for this site),
I host the servlets from home with this free domain:
webpelican.servebbs.com.
I didn't use any domain registration company for this
domain name - I simply used a free domain that some companies offer.
If you already have a server set up at home I recommend you to to install your own servlet engine - such as Tomcat Apache - to get a basic understanding of how servlets work.
You could then start expermenting within your local network, and perhaps use a domain service that offers a free domain to make the servlets on your local network accessible to users on the Internet without having them remember your ip-address. This can usually be done for both dynamic and static ip-addresses.
Eventually, when going online for real with your Web applications / Servlets, you could start thinking about domain registration companies and dedicated servlet hosting.
Feel free to use and/or alter any code in any way you like.
