Re: A couple of questions
The Servlet Spec doesn't require a /servlet/ mapping, but that's what everyone is used to, so I think the Tomcat developers put it in as a default. In the server.xml file there is a RequestInterceptor that handles requests to /servlet/: (server.xml) I believe this is how requests to /examples/servlet/HelloWorldExample are getting mapped to /WEB-INF/classes/HelloWorldExample.class. For a deeper explanation, you need to look at the code in org.apache.tomcat.request.InvokerInterceptor. --jeff - Original Message - From: "Lu, Spencer" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Friday, April 13, 2001 11:37 AM Subject: RE: A couple of questions > OK, I have just read the Servlet Specification 2.2, and it does not answer > my first question, which was: > > When I go to the Servlet Examples page > (http://localhost:8080/examples/servlets/index.html), there is a link that > executes the Hello World servlet.

RE: A couple of questions
OK, I have just read the Servlet Specification 2.2, and it does not answer my first question, which was: When I go to the Servlet Examples page (http://localhost:8080/examples/servlets/index.html), there is a link that executes the Hello World servlet. This link is http://localhost:8080/examples/servlet/HelloWorldExample. How does Tomcat know that when it sees "/examples/servlet/" in the URL, it is supposed to look in the examples/WEB-INF/classes directory for the HelloWorldExample.class file? I haven't been able to find anything in the server.xml or web.xml files that shows how this is configured. I see no servlet mappings in any of the configuration files that maps a servlet to "/examples/servlet/HelloWorldExample". Please tell me how this is set up.

RE: A couple of questions
first things first, you will have 90% of your questions answered by reading the servlet specification from Sun. this answers question 1 for you > 2) Would it be possible for me to place my application in a completely > separate directory tree and not in a war file?
