Execution of servlet

Question

i put my servlet class file in webapps/my_folder/web-inf/classes .
i entered
<servlet>
<servlet-name>
HelloWorld
</servlet-name>
<servlet-class>
HelloWorld
</servlet-class>
</servlet>
in the web.xml file at webapps/my_folder/web-inf/web.xml.
i added the Context tag in d server.xml file of tomcat/conf folder as
<Context path="" docBase="ruta" debug="0"
reloadable="true" crossContext="true">
</Context>
so that i get a url 2 execute my html/jsp pages as
http://localhost:9090/html/first.jsp & so on. & it works properly. i.e. my html & jsp r executed fine but when i try 2 execute d servlet it gives me an error like
Requested Resource is /servlet/HelloWorld is not available.
if i keep my servlet class file in either examples/web-inf/classes or root/web-inf/classes then it works but i want 2 keep my class file in my_folder/web-inf/classes only.

Answer 1

I tried almost everything 2 run a servlet class file from my own created folder as mentioned in my querry.
I wrote <servlet-mapping> tag including <url-mapping>, too in d web.xml file.
I have <context> tag in d server.xml file in d conf folder.
I removed d comment 4 d mapping of servlet invoker from d web.xml file from d conf folder.
I searched on various sites but still can't execute it.
So kindly help 4 my querry mentioned above.
