Answer 1

This is what I do:
In web.xml:
<servlet>
<servlet-name>servletname</servlet-name>
<servlet-class>servletclassname</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>servletname</servlet-name>
<url-pattern>/servletname</url-pattern>
</servlet-mapping>
Then I use a url without "servlet":
http://localhost:8080/name_folder_in_webapps/servletname
