Configuration for url-pattern in web.xml in Spring web application -

in spring app, have follow web.xml file:

<?xml version="1.0" encoding="utf-8"?> <web-app xmlns:xsi="http://www.w3.org/2001/xmlschema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemalocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" id="webapp_id" version="3.0">   <display-name>horariolivre2</display-name>    <welcome-file-list>     <welcome-file>acesso/login.html</welcome-file>   </welcome-file-list>    <servlet>     <servlet-name>horariolivre2</servlet-name>     <servlet-class>org.springframework.web.servlet.dispatcherservlet</servlet-class>     <load-on-startup>1</load-on-startup>   </servlet>    <servlet-mapping>     <servlet-name>horariolivre2</servlet-name>     <url-pattern>*.html</url-pattern>   </servlet-mapping> </web-app> 

my problem is: despite way page being found correctly, if change url-pattern '/', can't reach page (neither login page - first 1 project). try several combinations welcome-file, acesso/login, acesso/login/, /acesso/login, /acesso/login/ etc).

my spring-servlet.xml file is:

<?xml version="1.0" encoding="utf-8"?> <beans xmlns="http://www.springframework.org/schema/beans"         xmlns:xsi="http://www.w3.org/2001/xmlschema-instance"         xmlns:p="http://www.springframework.org/schema/p"         xmlns:context="http://www.springframework.org/schema/context"         xmlns:mvc="http://www.springframework.org/schema/mvc"         xmlns:tx="http://www.springframework.org/schema/tx"         xsi:schemalocation="         http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd         http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd         http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd         http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-2.0.xsd">          <context:component-scan base-package="com.horariolivre"/>             <bean id="viewresolver" class="org.springframework.web.servlet.view.urlbasedviewresolver">                 <property name="viewclass" value="org.springframework.web.servlet.view.jstlview" />                 <property name="prefix" value="/web-inf/jsp/" />                 <property name="suffix" value=".jsp" />             </bean>          <context:annotation-config>             <bean class="com.horariolivre.resources.hibernateconfig">             </bean>         </context:annotation-config>          <tx:annotation-driven transaction-manager="transactionmanager"/> </beans> 

and 1 of controller is:

@controller @requestmapping(value="acesso") public class primarycontroller {      @autowired     private sessaohome sessao;      @autowired     private usuariohome usuario;      @requestmapping(value="login")     public modelandview login() {         modelandview mav = new modelandview();         mav.setviewname("acesso/login");         return mav;     }     (...) } 

someone know right path should use url-pattern '/'?

you can give url-pattern * or /*
