In this chapter we will focus on networking apps; however, the same code techniques can also be applied to applets. The important issue with applets is security. When creating a networked applet, it is only possible to connect to the computer that the applet was executed from (i.e., the web server). However, this is no problem as long as your game server is running on the same machine as the web server. Note that it is possible to get around this by creating a signed applet, but this process requires an official certificate and is generally a lot of hassle unless you are a big-shot company with money to spend. Signed applets are really beyond the scope of this tutorial.
