Spring @Scheduled task runs twice

I am creating an `@Scheduled` task to run every 5 seconds. As has been a problem in other questions, my task is running twice! I have looked at other questions, and read the applicable documentation here, but I have not been able to figure out the problem. I know that two seperate instances of my `@Scheduled` class are getting instantiated when I start my tomcat server. I have also figured out when they are instantiated in reference to my log file. One associated with this log line : INFO: Initializing Spring root WebApplicationContext and another with this log line: INFO: Initializing Spring FrameworkServlet 'servlet' Here is the spring config file. ``` <beans xmlns="http://www.springframework.org/schema/beans" xmlns:context="http://www.springframework.org/schema/context" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:security="http://www.springframework.org/schema/security" xmlns:task="http://www.springframework.org/schema/task" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.1.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd http://www.springframework.org/schema/security http://www.springframework.org/schema/security/spring-security-3.2.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd http://www.springframework.org/schema/task http://www.springframework.org/schema/task/spring-task.xsd"> <context:component-scan base-package="web.controllers"/> <context:component-scan base-package="services"/> <context:component-scan base-package="dao"/> <context:component-scan base-package="scheduled"/> <context:property-placeholder location="/WEB-INF/application.properties"/> <mvc:annotation-driven/> <mvc:default-servlet-handler/> <task:annotation-driven /> ``` And my simple java class: ``` package scheduled; import org.springframework.scheduling.annotation.Scheduled; import org.springframework.stereotype.Service; @Service public class Notifier { @Scheduled(fixedDelay = 5000) public void notifyUsersOfBidItems() { try { System.out.println(this); } catch (Exception e) { e.printStackTrace(); } } } ``` Also, I am using Spring 4.
