what server you have? tomcat or weblogic, or Jserv?

   then don't create your own directory,

   you place your servlet programs in .../web-inf/classes/HelloWorld.java
then you compile

  then you run http://localhost:8080/examples/servlet/HelloWorld
file name is case sensitive. be aware in that.
if you want to create your own directory, you have to create package.
but i have no idea about that
