Error 404 on Tomcat 5.x w/ simple helloworld

Question

since my first Tomcat installation (about 2 weeks ago) i can't execute a servlet.
I've red in many topics ... my question is:
Under webapps i've create:
examples
|--WEB-INF
|--classes
and put my hello.class in it.
Also create web.xml in WEB-INF folder as:
<webapp>
<display-name>hello</display-name>
<description>hello</description>
<servlet>
<servlet-name>hello</servlet-name>
<servlet-class>hello</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>hello</servlet-name>
<url-pattern>/examples</url-pattern>
</servlet-mapping>
</webapp>
I have red somewhere to modify server.xml & insert the context path
When i opened server.xml i looked a lot of section <service ... listener ... engine ...
where have i put the context path tag?
and how is the code?
Is that enough to run my servlet?
P.S.: Tomcat 5.x doesn't configure any webapps/examples folder by default!
Thks in first

Very good - this is correct. I'd recommend that you rename that directory under webapps to something else, anything other than examples. Call it MyFirstServlet.
and put my hello.class in it.You should put your hello.class in a package of some kind. Tomcat doesn't play nicely with servlets and beans that aren't in packages. You'll have to add "package" to your source and recompile, of course.
Also create web.xml in WEB-INF folder as:No, this is incorrect. Your web.xml does go in WEB-INF, but it should look like this:
<webapp>
    <display-name>hello</display-name>
    <description>hello</description>
    <servlet>
        <servlet-name>hello</servlet-name>
        <servlet-class>yourPackage.hello</servlet-class>
    </servlet>
    <servlet-mapping>
        <servlet-name>hello</servlet-name>
        <url-pattern>/hello</url-pattern>
    </servlet-mapping>
</webapp>

You don't need to modify server.xml at all.
Now your browser URL will look like this:
http://localhost:8080/MyFirstServlet/helloSee if this works.
I'd also recommend that you follow the Sun Java coding conventions and start class names with a capital letter.
