http status 404 error

[V Gala]

Hi
I am using tomcat 5.0.28 and jdk1.5.0_15
Using http://localhost:8080 -> tomcat home page is open
but when I type http://localhost:8080/ch1/serv1 at browser it is giving http error 404

type Status report

message /ch1/serv1

description The requested resource (/ch1/serv1) is not available

I think my folder structure is proper
and content of web-XML is shown below
<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>Chapter1 servlet</servlet-name>
<servlet-class>Ch1Servlet</servlet-class>
</servlet>


<servlet-mapping>
<servlet-name>Chapter1 servlet</servlet-name>
<url-pattern>/serv1</url-pattern>
</servlet-mapping>

</web-app>

I tried uncommenting the line in conf/web-xml (servlet-mapping)
Then also it is not working.
please help
Thanks in advance

Hi,

are you sure your application gets deployed correctly (check Tomcat log directory)? If yes, which context is used? Is it really "/ch1".

Depending on your IDE there could be a context.xml file anywhere in your project. Check if it looks something like this:

<?xml version="1.0" encoding="UTF-8"?>
<Context path="/ch1"/>

Your servlet mapping in web.xml looks correct for me. Therefore I'd rather think it's a problem of the web context!

I think my folder structure is proper

Could you show it ?

[swapna rao]

try by placing your class file in some package and modify the web.xml accordingly.

[V Gala]

I tried by putting my classes in package it is not working
Even I am not able to run servlets-examples but able to run jsp-examples
