You have nothing telling tomcat to map a URL to your registered
servlet. You would do that like this:
<servlet>
<servlet-name>hello</servlet-name>
<servlet-class>foo.bar.baz.HelloWorld</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>hello</servlet-name>
<url-pattern>/hello</url-pattern>
</servlet-mapping>
note that the "<servlet-name>" does not have anything to do with mapping a
URL. It is strictly for referring to a specified servlet in the web.xml file.
Also, make sure you put ALL <servlet> tags BEFORE <servlet-mapping> tags.
Do this and your example will work like a charm.
Keep in mind that if you want this to run through Apache on port 80, you
will have to provide this mapping again in the mod_jk.conf connector config
file by adding:
JkMount /practice/hello ajp13
after adding that, you would need to restart Apache to reload the
mod_jk.conf file.
