java - How to properly map a servlet -

i have mapped servlet this

<?xml version="1.0" encoding="utf-8"?>  <web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/xmlschema-instance" xsi:schemalocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">      <servlet>          <servlet-name>s1</servlet-name>          <servlet-class>firstservlet</servlet-class>      </servlet>      <servlet>          <servlet-name>s2</servlet-name>          <servlet-class>secondservlet</servlet-class>      </servlet>      <servlet-mapping>          <servlet-name>s1</servlet-name>          <url-pattern>/servlet1/*</url-pattern>      </servlet-mapping>      <servlet-mapping>          <servlet-name>s2</servlet-name>          <url-pattern>/servlet2/*</url-pattern>      </servlet-mapping>      <session-config>          <session-timeout>              30          </session-timeout>      </session-config>      <welcome-file-list>          <welcome-file>index.jsp</welcome-file>      </welcome-file-list>  </web-app>

thing whenever write in url

case1 : localhost:2040/sampleerror/servlet2/name

case2 : localhost:2040/sampleerror/servlet2/name/surname

it goes same servlet know haven't done url mapping please suggest me modification in case 2 should show 404 error resources not available

actually application name "sampleerror" "name" , "surname" in url dynamic 1 mean can give there insead of "name" can give name or

change web.xml mapping this:

 <servlet-mapping>         <servlet-name>s2</servlet-name>         <url-pattern>/servlet2/name</url-pattern>     </servlet-mapping> 

the pattern /servlet2/* means url containing servlet2 string in uri mapped secondservlet. thats reason both /name , /name/surname being handled secondservlet
