Hi, I am a beginner in Java Programming, can you give more explanation on the TRY IT exercise. I have done Step 1 - created the html following the booksearch.html example. I don't understand Step 2. I downloaded the code in Lesson 27, but the code on StockServer.Java, is it a servlet? If not, can you please show me how to create a new servlet called StockSErverServlet that will take one parameter, the stock symbol, and instantiate a class called StockQuoteGenerator as stated in Step 2 in the book.

Thank you.
