Maybe you've already done this, but before jumping to a "solution," you might want to back up a little and define your requirements: What exactly are you trying to do?
As a first step, I suggest searching your host's help or FAQ pages for tutorials that might guide you. In doing this, search based on your requirements (for example, "create mailing lists") instead of what you think might be a solution (for example, "servlets"). Depending on your host, there might be something already in place that will make it easier for you than developing servlets.
