1) Do yoiu mean how to "run" your servlet code with sample parameter? This call manual testing with a sample run of you code. You need a web server(eg Tomcat), create a webapp with your servlet then deploy it there in order to run it.
2) httpunit and junit are framework to write test case code that can be automated and repeatable. Plz read their doc.
3) Your sample code me a very wrong way to retrieve and convert servlet parameters.
Get a java toturial and servlet tutorial book and read it over the weekend. You need to get at least the basic.
