Downloaded (git cloned) latest version of spark-basic-structure. First, did not compile with errors for multiple constructors and accessor methods not present in Book.java and User.java. Implementing those methods in the obvious way allows the project to compile.
However, on running the application, I see the following web application error.
I reproduced the exact same error both on a Win 10 machine, and MacOS 10.13 machine. Java RE 1.8. Project built by importing into Eclipse.
This is my first attempt to use spark java for anything. So, machines may not be properly configured (?).
Should this code be buildable and runnable at this point? Any idea why it doesn't? Most interested in the runtime error.
