Tapestry and Tomcat

[Nasir Munir]

Tools I am using are:
Tapestry 4.x
Tomcat 5.5.x
Eclipse java europa
Situation:
I can see tomcat up and running
Problem:
Now when I am trying to use Tapestry to run Hello World application, I am running into problems. It is perhaps not recognizing the file, as it is showing me page not found error.
Error message:
Document base (the path which I am providing in the context file) does not exist or is not a readable directory.
What I have done so far:
I can see Home.html and Home.page and web.xml in the C:\workspace\Hello World\context\WEB-INF. Also the HelloWorld.xml (context file) is there C:\Tomcat\conf\Catalina\localhost. I am following the example from the book and have checked the contents many a time and cannot find any mis-match with that. I have double checked the path in the context file as well and it is telling tomcat to look in the workspace directory for the html page. I can post the file contents if that can make it more clear, but rest assured it is the same as from book.
Can I get some help here?, thanks

Well, the first question is: to which URL you are trying to navigate when you are getting the 404 error. If you are following Kent Tong's book, it should be something like http://localhost:8080/HelloWorld/app.

If you are doing this (to not forget /app in the end!) then please list the contents of your web.xml.

Cheers,

sorry for not explaining my question properly.
Yes I am using the book by Tong.
I have been using this URL to navigate to the page:
http://localhost:8080/HelloWorld/app

The contents of web.xml are:

<?xml version="1.0"?>
<web-app xmlns="http://java.sun.com/xml/ns/j2ee"
xmlns:xsi="http://www.w3.org/TR/xmlschema-1/"
xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd" version="2.4">
<display-name>HelloWorld</display-name>
<servlet>
<servlet-name>HelloWorld</servlet-name>
<servlet-class>org.apache.tapestry.ApplicationServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>HelloWorld</servlet-name>
<url-pattern>/app</url-pattern>
</servlet-mapping>
</web-app>

Hmm... Everything seems to be all right. It can be just a simple typo somewhere.

are you the one who wrote step by step jakarta - tapestry ? It gives me immense pleasure to know that you are answering my questions.
I am trying to set up tapestry framework at home, and I will try to re-do the whole setup, I hope it should work this time.
At any rate, please update the tapestry installation from version 3.x to 4.x. I liked your article and was very helpful. If you could update that to latest version, that would be great.
Thanks a lot for all your help. Tapestry seems a little complicated, not that I am giving up on it. I hope with more time spent on that, I will be in a better position to understand that well.
Thanks again.
