Spring 3.1 & Tomcat 7.0.23 & task scheduler multiple invocations

[janskyview@gmail.com]

Hi every one,

my spring.xml looks like

<task:scheduler id="feedServiceScheduler"  pool-size="10"/>
<task:scheduled-tasks scheduler="feedServiceScheduler">        
    <task:scheduled ref="feedService" method="testMethod" cron="0 50 11 * * *" />
</task:scheduled-tasks>

I expect method "testMethod" to be invoked on object "feedService" at 11:50 every day of the year
For some reason testMethod is invoked twice and I just can't find a solution to the problem.

"feedService" bean is nothing fancy, just a simple POJO and test method prints out a message.

Any help about what I might be doing wrong would be great.

Thanks //janskyview

My guess you are loading the configuration twice.. You are either importing the xml containing this declaration or explicitly defining the xml for both the ContextLoaderListener and DispatcherServlet.

Please use code tags... As I stated you are loading the files twice... Both the CLL and DS are loading the spring.xml... Simply don't do that. The DS should only have to load the web related stuff, the CLL the application and infrastructure beans.

Hi,

CCL is commented out actually, right now for the sake of clarity I stripped out the web.xml file of everything else and now looks
like:

<?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">

 	
	
	<!-- Spring Servlet &  Mapping -->
	<servlet>
		<servlet-name>springServlet</servlet-name>
		<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
		<init-param>
			<param-name>contextConfigLocation</param-name>
			<param-value>/WEB-INF/settings/spring.xml</param-value>
		</init-param>
		<load-on-startup>1</load-on-startup>
	</servlet>		
	<servlet-mapping>
		<servlet-name>springServlet</servlet-name>
		<url-pattern>/spring/*</url-pattern>
	</servlet-mapping>

	<!-- Log4J Configuration Listener  & Configuration File -->
	<listener>
		<listener-class>org.springframework.web.util.Log4jConfigListener</listener-class>
	</listener>
	<context-param>
		<param-name>log4jConfigLocation</param-name>
		<param-value>/WEB-INF/classes/log4j.properties</param-value>
	</context-param>


</web-app>

but same result...any direction you would to go search where the problem is?

You must be loading it a second time somewhere... You don't construct an applpicationcontext yourself somewhere?
