Java Forum / General / September 2006servlet 101 question
I am attempting to write an HelloWorld servlet with tomcat and of course I can't get it to work. I am trying to run the first servlet from the CoreServlets book. according to the book I can create a directory, place the servlet class file, in the directory and invoke it in a browser. I compiled the servlet and I placed it in a directory under the webapps directory. Well of course this didn't work. so where should I place the class file???. btw, I was able to place a plain html file in the directory and get it to run. I am running tomcat 5.5 with winxp. thanks for the help john Okay, so I figured it out. I needed to create a web-inf directory and use a web.xml file. Strange this isn't mentioned for the first example in the book. thanks > I am attempting to write an HelloWorld servlet with tomcat and of > course I can't get it to work.

Older versions of Tomcat (3.3 or so) did not require a WEB-INF/web.xml; current ones (I think at least from 4.0 onwards) do. WEB-INF/web.xml is a requirement of the servlet specification, so the current behaviour is correct (even though it requires a bit more work). I guess the Core Servlets book is written for Tomcat 3.3 (if so, it also lacks information on some of the changes in later servlet specification versions).  SignatureWolf a.k.a.

O'Reilly's Head First Servlets and JSP has correct information for deployment and other niceties. I found it very accurate, and it has a lot of info too. If the OP wants to pick up a more up-to-date book, I'd recommend HFSJ. thanks to both for the info. I'm off to bookpool :) cheers > > I guess the Core Servlets book is written for Tomcat 3.3 (if so, it also > > lacks information on some of the changes in later servlet specification [quoted text clipped - 4 lines] > accurate, and it has a lot of info too.

To get the basics on Tomcat, there is the "First Webapp" chapter (http://tomcat.apache.org/tomcat-5.5-doc/appdev/index.html) in the documentation. This'll guide through creating and deploying a simple webapp, while also describing the basics of a typical development environment. Then, looking from the other side, the Java EE tutorials from Sun contain good information on the different technologies, such as servlets, JSP and so on; http://java.sun.com/javaee/reference/tutorials/ especially http://java.sun.com/j2ee/1.4/docs/tutorial/doc/Overview7.html#wp79959 http://java.sun.com/j2ee/1.4/docs/tutorial/doc/Overview7.html#wp79962 SignatureWolf a.k.a.
