Writing Servlets
Next Steps
Now that we have a few simple servlets under our belt, the next step is to build on this foundation.
Servlets are great for doing simple tasks and filtering information.
However, in the real world, true Web applications are rarely limited to a set of standalone programs on a Web Server.
Rather, the Web applications themselves interface with other sources of data.
In this context, data can mean anything.
It can consist of anything from text files to a complex system of multiple custom network servers distributed all over the world.
Although this article provided an overview of servlets in a nutshell, it is by no means a comprehensive "This is everything you can do with servlets" tutorial.
Marty Hall's Introduction To Servlets and JSP Tutorial Series provides an indepth look at Servlets.
Throughout the Java Networking series we will refer to Marty's tutorial for more detailed explainations of various Servlet techniques, allowing us to focus on the use of Networking and Distributed programming technologies with Servlets.

Next time, we will focus on the data source API that most people tend to use with Servlets: Java DataBase Connectivity (JDBC).
This introduction to JDBC will lead us into writing servlets that can communicate with back-end relational databases such as Oracle, Sybase, or Microsoft SQL Server.
