applicationcontext-security.xml

<?xml version="1.0" encoding="utf-8"?> <beans:beans xmlns="http://www.springframework.org/schema/security" xmlns:xsi="http://www.w3.org/2001/xmlschema-instance" xmlns:beans="http://www.springframework.org/schema/beans" xsi:schemalocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/security http://www.springframework.org/schema/security/spring-security-3.0.xsd"> <http auto-config="true">     <intercept-url pattern="/register.html" access="is_authenticated_anonymously" />     <intercept-url pattern="/*" access="role_user, role_admin" />            <logout logout-url="/logout"/> </http>  <beans:bean id="myuserdetailsservice" class="labas.spring.service.userdetailsimp"/>  <authentication-manager>     <authentication-provider user-service-ref='myuserdetailsservice'/> </authentication-manager> 

some why when run

java.lang.illegalstateexception: no webapplicationcontext found: no contextloaderlistener registered?

what wrong?

you haven't declared root webapp context - you've added contextconfiglocation, not listener uses it:

<listener>     <listener-class>org.springframework.web.context.contextloaderlistener</listener-class> </listener>
