Note: to run this project on Windows or Linux/Mac with the embedded DB H2 (easiest way):
0. If running on pe07, edit src/main/resources/application.properties and
  set the port to one of your assigned ports, preferably xxxx2 to follow
  our conventions (for example, 51302). See CS636Ports.html for your ports.
  If running at home, just use the one already set up, 9002.

1. Load the pizza database if needed (this uses same db as in pizza1 and pizza2's
just has the one extra table, so will work too). Delete the H2 DB file in your
home directory, as we are upgrading H2 to version 200 here. Then reload it.
Just cd to the database directory here and use the db tools there, same as in pizza1.
   
2. Use "mvn clean package" when cd'd to this directory to build the jar

3. On Linux or Mac, use "chmod +x *.sh" to make all shell scripts in this directory
 executable, and similarly for the database directory. 

4. Run the program to start the webapp: using convenience script
    runJarByProfile h2 web  (Windows, add .sh for Linux/Mac)   
or using mvn directly (see contents of runMvnByProfile). Either way, let it hang.

5. Browse to localhost:9002/welcome.html to see pizza shop site. Replace 9002 here
with your own port ending in 2 if running on pe07.

6. Run all the JUnit tests with mvn test. They are also run during mvn package.

7. The old line-oriented programs can be run outside of tomcat:
    runJarByProfile h2 SystemTest  (Windows)   (or TakeOrder or ShopAdmin)
or  runJarByProfile.sh h2 SystemTest  (Linux or Mac)

To use a real DB: you need to define environment variables 
 For Oracle database, set up env variables ORACLE_USER, ORACLE_PW, ORACLE_SITE
  For MySQL use, set up env vars MYSQL_USER, MYSQL_PW, MYSQL_SITE, and for
  home runs, set up the tunnels. All this is the same as for pizza1.

Then these are accessed from the profiles to set up the JDBC config.
So you can run simply  runJarByProfile oracle web   for example, and
let it hang.

There are newer versions of the Oracle and MySql drivers in use here:
the ones in lib-for-ant are copies of the ones selected by Spring Boot using its
version control. We shouldn't see the SSL bug problem in mysql now.
