[Star Prog]

Hallo all,

I'm running Eclipse Indigo 3.7, apache Tomcat 7, SpringMVC 2.5.6, JDK1.7. I'm trying to do the tutorial that is here. I'm having the following error msg:

These are the librairies I had included in the project:

-jakarta-commons/commons-logging.jar
-mysql-connector-java-5.1.18
-j2ee/jstl.jar
-log4j/log4j-1.2.14.jar
-jakarta-taglibs/standard.jar
-dist/spring.jar
-dist/modules/spring-webmvc.jar
-spring-web.jar

There are 4 xml files in the project:

-applicationContext.xml
-web.xml
-springapp-servlet.xml
-log4j.xml

Their source code are:
