can't find my mistake trying HFSJ ServletContextListener demo

[Patrick Beck]

hi ranchers,

I'm trying ServletContextListener demo code starting on page 168 of HFSJ.
When running the URL http://localhost:8080/listenerTest/ListenTest.do in the webbrowser, the following error occured:

HTTP Status 404 - /listenerTest/ListenTest.do

type Status report

message /listenerTest/ListenTest.do

description The requested resource (/listenerTest/ListenTest.do) is not available.
Apache Tomcat/5.5.20

I checked several times web.xml and classes directory and couldn't find my mistake.

Here's my web.xml:

<web-app xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd" version="2.4">

<servlet>
<servlet-name>ListenerTester</servlet-name>
<servlet-class>com.example.ListenerTester</servlet-class>
</servlet>

<servlet-mapping>
<servlet-name>ListenerTester</servlet-name>
<url-pattern>/ListenTest.do</url-pattern>
</servlet-mapping>

<context-param>
<param-name>breed</param-name>
<param-value>Great dane</param-value>
</context-param>

<listener>
<listener-class>com.example.MyServletContextListener</listener-class>
</listener>

My directory structure in tomcat webapps:

ds@toshiba:~/prog/apache-tomcat-5.5.20/webapps/listenerTest$ l

Check Tomcat's log files.
Also check that ListenerTester class is public.

I forgot the ending </web-app> in web.xml *doh*
Thanks for help, I didnt realize that.

Always indent your code, even when you don't use an IDE.
