This is actually pretty easy to understand.
When you do something like
StandardEngine engine = ...;
System.out.println("My engine is " + engine);
Java automatically calls engine.toString() for you. Most (but not quite
all, obviously) of the core Catalina components override toString() to
print out something reasonable. If you get
StandardEngine[null]
that just means you have not called engine.getName() yet -- afterwards, it
will print whatever name you've assigned it inside the square brackets.
