We will create a new Dynamic Web Application which displays lotto numbers, and deploy it to Tomcat.

1. Create a new Dynamic Web Project called LotteryApp.
2. Select the option to generate the web.xml deployment descriptor.
3. Configure the project to use Maven.
4. Add the servlet-api dependency.

   <dependencies>
      <dependency>
          <groupId>javax.servlet</groupId>
          <artifactId>javax.servlet-api</artifactId>
          <version>3.1.0</version>
      </dependency>
   </dependencies>
   

5. Create a new servlet com.example.lotto.servlets.LotteryServlet.
6. Be sure to extend HttpServlet.

7. Override doGet().

8. Create a new HTML page, src/main/webapp/index.html. This will be the homepage of your web app.

9. Add a link to numbers reading Get Lotto Numbers.

10. Configure web.xml:

11. index.html is the welcome file.

12. Map LotteryServlet to the URL /numbers.

13. Run your web app on Eclipse's Tomcat Server. Issues are likely mapping or file locations. Make sure index.html is in the src/main/webapp folder.

14. Your LotteryServlet class will get PowerBall numbers from another class.

15. Use DynamicWebApps/com.example.lottery.powerball.PowerBallDrawing, which returns a PowerBallDrawingResult object, or copy your PowerBall code.

16. In your servlet, use the PowerBall classes to generate PowerBall numbers, and add the numbers to the response as HTML.
