No applications were found for the registrar in the Spring Framework: WARN: WARN section (org.springframework.web.context.ContextLoader)

I have been trying all day to solve the logging problem that I encountered log4j in webapp. No matter what I do, I cannot get rid of the following:

log4j:WARN No appenders could be found for logger (org.springframework.web.context.ContextLoader). log4j:WARN Please initialize the log4j system properly. log4j:WARN See http://logging.apache.org/log4j/1.2/faq.html#noconfig for more info.

To be clear, I read all the articles here in the Stack Overflow section, addressing this issue. I read the log4j manual. I went through a dozen different textbooks. I tried the property approach and the XML approach (log4j.properties and log4j.xml, respectively). In addition, I confirmed that the log4j.xml file is being read. In addition to the fact that the server tells me this at startup, I can influence the feedback level through an XML file. So yes, the log4j.xml file is in CLASSPATH.

I know that I am missing something simple and fundamental. The following are the relevant files:

LOG4J.XML (/ WEB-INF):

 <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE log4j:configuration PUBLIC "-//APACHE//DTD LOG4J 1.2//EN" "log4j.dtd"> <log4j:configuration xmlns:log4j="http://jakarta.apache.org/log4j/"> <!-- Appenders --> <appender name="console" class="org.apache.log4j.ConsoleAppender"> <param name="Target" value="System.out" /> <layout class="org.apache.log4j.PatternLayout"> <param name="ConversionPattern" value="%-5p: %c - %m%n" /> </layout> </appender> <!-- Application Loggers --> <logger name="com.tiersoftinc.testlog"> <level value="info" /> </logger> <!-- 3rdparty Loggers --> <logger name="org.springframework.core"> <level value="info" /> </logger> <logger name="org.springframework.beans"> <level value="info" /> </logger> <logger name="org.springframework.context"> <level value="info" /> </logger> <logger name="org.springframework.web"> <level value="info" /> </logger> <!-- Root Logger --> <root> <priority value="warn" /> <appender-ref ref="console" /> </root> </log4j:configuration>

and WEB.XML (/ WEB-INF):

 <?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"> <!-- The definition of the Root Spring Container shared by all Servlets and Filters, and the applicationContext.xml file --> <context-param> <param-name>contextConfigLocation</param-name> <param-value> /WEB-INF/spring/root-context.xml /WEB-INF/spring/app-context.xml </param-value> </context-param> <!-- Logging listener --> <listener> <listener-class>org.springframework.web.util.Log4jConfigListener</listener-class> </listener> <context-param> <param-name>log4jConfigLocation</param-name> <param-value>/WEB-INF/log4j.xml</param-value> </context-param> <!-- Creates the Spring Container shared by all Servlets and Filters --> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <!-- Processes application requests --> <servlet> <servlet-name>appServlet</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <param-name>contextConfigLocation</param-name> <param-value>/WEB-INF/spring/appServlet/servlet-context.xml</param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>appServlet</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping> </web-app>

and APP-CONTEXT.XML (/ WEB-INF / spring):

 <?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:context="http://www.springframework.org/schema/context" xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:p="http://www.springframework.org/schema/p" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.1.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.1.xsd"> <!-- Activates various annotations to be detected in bean classes --> <context:annotation-config /> <!-- Scans the classpath for annotated components that will be auto-registered as Spring beans.

and APP-CONTEXT-MONGO.XML (/ WEB-INF / spring):

 <?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:c="http://www.springframework.org/schema/c" xmlns:tx="http://www.springframework.org/schema/tx" xmlns:context="http://www.springframework.org/schema/context" xmlns:mongo="http://www.springframework.org/schema/data/mongo" xmlns:util="http://www.springframework.org/schema/util" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.1.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.1.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.1.xsd http://www.springframework.org/schema/data/mongo http://www.springframework.org/schema/data/mongo/spring-mongo-1.0.xsd http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-3.1.xsd"> <!-- Activate Spring Data MongoDB repository support --> <mongo:repositories base-package="com.tiersoftinc.gridlab3.repository" /> <bean id="propertyPlaceholderConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer"> <property name="locations"> <list> <value>/WEB-INF/spring/database.properties</value> </list> </property> </bean> <!-- MongoDB host --> <mongo:mongo host="${mongo.host.name}" port="${mongo.host.port}"/> <!-- Template for performing MongoDB operations --> <bean id="mongoTemplate" class="org.springframework.data.mongodb.core.MongoTemplate" c:mongo-ref="mongo" c:databaseName="${mongo.db.name}"/> <!-- Service for initializing MongoDB with sample data using MongoTemplate --> <bean id="initGridLab3Service" class="com.tiersoftinc.gridlab3.services.InitGridLab3Service" init-method="init"/> </beans>

and finally ROOT-CONTEXT.XML (/ WEB-INF / spring):

 <?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:context="http://www.springframework.org/schema/context" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.1.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.1.xsd"> <!-- Root Context: defines shared resources visible to all other web components --> <context:annotation-config /> </beans>

What am I missing?

Thanks.

Have you tried this?

  <logger name="org.springframework.web"> <level value="info" /> <appender-ref ref="console" /> </logger>

Put these lines at the beginning of web.xml

 <listener> <listener-class>org.springframework.web.util.Log4jConfigListener</listener-class> </listener> <context-param> <param-name>log4jConfigLocation</param-name> <param-value>classpath:/main/resources/log4j.xml</param-value> </context-param>
