404 Not Found

[mary]

When I try to run the servlet the server return to me and exception
I created servlet "HelloWorld" and saved it under webapps>ROOT>utils>WEB-INF>classes.
I created the web.xml file to map it, and I saved it under webapps>ROOT>utils>WEB-INF.

when I click http://localhost:8080/utils/hello to run servlet, appears:
404 Not Found /utils/hello was not found on this server.

what's the problem?

Hi,
It could be your web.xml file. U have to do the right mapping between the page and the .class file.
Try to show us your web.xml please.
Bye.

I created the web.xml file to map it, the web.xml look likes below and saved it under webapps>ROOT>utils>WEB-INF.

Code:

<web-app xmlns="http://sor.com/ns/resin">
<servlet servlet-name="hello"
servlet-class="Hello"/>

<servlet-mapping url-pattern="/hello"
servlet-name="hello"/>
</web-app>

take the utils directory from root and place it under webapps directory. so, now new path is tomcat>webapps>utlis>WEB-INF>
make new dir classes under WEB-INF and place the class Hello in classes.

make web.xml as follows and place it under WEB-INF:
<?xml version="1.0" encoding="ISO-8859-1"?>
<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 http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"
version="2.4">
<servlet>
<servlet-name>hello</servlet-name>
<servlet-class>Hello</servlet-class>
</servlet>

<servlet-mapping>
<servlet-name>hello</servlet-name>
<url-pattern>/hello</url-pattern>
</servlet-mapping>

</web-app>

This will work

and type the following url in browsers address bar:
http://localhost:8080/utils/hello
to run servlet

better way u can use this structure
In webapps create MyApps in that create WEB-INF in this u can copy that web.xml file.
In WEB-INF create classes folder.

since it is a servlet... i think the url should be http://localhost:8080/utils/servlet/hello
if you are using tomcat
