simple HelloWorld example -> 404
I'm a novice and I'm working through the Tomcat documentation.
(I'm using Tomcat 5.) I've gotten to step 3,
http://localhost:8080/tomcat-docs/appdev/deployment.html
I'd previously compiled the "HelloWorld" example from the O'Reilly book on
Java Servlet Programming by Hunter. I then wanted to run it from the
browser, so I set up something like the servlets-examples that also has a
HelloWorldExample, so I did the following:
1. created a "foo" directory under $CATALINA_HOME/webapps
2. created a WEB-INF directory under "foo"
3. created a "classes" directory under WEB-INF
4. copied the HelloWorld.java and HelloWorld.class files to
the "classes" directory and made them world readable.
5. chmod all directories 755
6. created a web.xml file from tomcat-docs/appdev/web.xml.txt
7. created an index.html file under "foo" that has a hyperref to
"servlet/HelloWorld"
8. restarted Tomcat
I checked the log files and I've eliminated the parsing errors for the
web.xml file. I'm able to visit the index.html file, but when I click on
the
link to "servlet/HelloWorld" I get a 404.
Note that the web.xml.txt file says that I should be able to execute my
servlet just by accessing localhost:8080/foo/servlet/HelloWorld, yet I'm
not able to do so. I think that means that the problem isn't in my web.xml
file (even though that's the most complicated and error-prone step).
I also tried putting the HelloWorld.* files in
webapps/ROOT/WEB-INF/classes,
as directed in the Hunter book, but that didn't work either (404).
Anyone have any ideas on how to get this very simple example working?
Thanks,
Scott

Where is your web.xml located? And if it is located inside foo/WEB-INF/
then have you tried accessing the servlet when you remove the web.xml?

Examples with /servlet/ in the URL usually depend upon the Invoker Servlet
being enabled. It is now disabled by default, and although it's more
frustrating in the beginning, it's better to leave it that way and learn to
configure your Servlets.

Put <servlet> and <servlet-mapping> tags into web.xml, and then access the
Servlet using the URL that you configured, NOT the one with /servlet/ in it.
Check the DTD for the required order of tags in web.xml.
