Chris,
No, I haven’t seen those replies, but I have changed from JavaFX to Jakarta, as
StackOverflow suggested that, too.
What I’m experiencing now, is the old version of my HelloWorld class running,
when I’ve updated it slightly, have recompiled it, and have placed the new
class file in the webapps directory.
Do you, or does anybody else have sny servlet book suggestions?
Amazon only had this and one other that was even older.

Just FYI, a book written in 2010 will be using the Java EE or old
servlet, etc. package names while Tomcat 10 will want you to use the new
ones. Without going into too much detail, you basically want to change
every instance of:
javax.[stuff]
To:
jakarta.[stuff]

That's appropriate, depending on the error(s) you are seeing. A book
about Java servlets and containers is already going to be pretty long;
adding the details of HTTP would roughly double the size of the book.

Did you see any of the replies sent back to this list on this topic from
Jan 10th and Jan 11th? I think there are already some ideas in there,
and some questions, too.
