Good evening everyone,
I am just starting out with Java servlets in Tomcat 10.1.4.
I’m learning them using a book written in 2010, of which I don’t remember the
authors’ names.
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]
The book does a good job of explaining code samples, but doesn’t
describe any solutions to HTTP errors.
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.
I have a HelloWorld servlet, located in my
tomcat_home/webapps/servlet_files/classes/hello_app directory, with
the corresponding web.xml file located just outside of that folder.
The same directory structure is the same for servlet #2. The URL
pattern for HelloWorld is /HelloWorld, and the second servlet’s
web.xml URL pattern is /HelloWorld_Two. In both instances, I receive
HTTPError 404 messages when attempting to run either of them. >
Can anybody help me?
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.
