Head First Servlets and JSP, 2nd Edition

Key steps for servlet version two

We have two main things to do: recompile the servlet and deploy the model class.

Compiling the servlet

We’ll use the same compiler command that we used when we built the first version of the servlet.

Deploying and testing the web app

Now, in addition to the servlet, we also have to deploy the model. The key steps are:

1 - Move a copy of the servlet .class file to: ../Beer-v1/WEB-INF/classes/com/example/web/ This replaces the version one servlet class file!

2 - Move a copy of the model’s .class file to: ../Beer-v1/WEB-INF/classes/com/example/model/

3 - Shutdown and restart tomcat

4 - Test the app via form.html, the final browser output should be something like:
