Hi Jacob and thanks for your response. I tried your suggestion regarding servlet mapping and it helped - I can now execute servlets in the default package but I get the same message when try to access a servlet that is not in the default package....oh yes Tomcat is shutdown while I deploy my servlets..
As to a your point about buying some books etc.,...I will be the first to agree with you that I don't know everything about Tomcat, but I want to point out that I have spent a lot of time reading about servlets and Tomcat from a vareity of sources. Some books I have read include Jason Hunter's Java Servlets (unfortunately, the first edition), James Goodwill's Apache Jakarta-Tomcat from Apress (very recent), David Harms, JSP, Servlets, and MySQL, and Marty Hall's Servlets and JavaServer Pages. So please be assured this is not a case of just firing off a question to the list without doing some research first. I agree with you that this is pretty basic stuff - and the books I mentioned seem to outline it pretty well, but all the examples deploy to webapps/ROOT which is not what I am trying to do. Even so, this is pretty straight forward stuff which is why it surprises and frustrates me when something so simple becomes a road block. So I posted my question in hopes that someone would point out what I was doing wrong. Lastly, do you know the in which version the default invoker was changed, because I don't recall having to change conf/web.xml before.
