Please read UseCodeTags and BeForthrightWhenCrossPostingToOtherSites you have also posted this question here:

http://forum.springsource.org/showthread.php?129270-Hello-World


I would say you need to find a better tutorial for learning Spring MVC this one has some issues. I suggest you download STS

http://www.springsource.org/sts

STS is eclipse with all the Spring stuff bundled. Once you download it go to File -> new Spring Template Project -> Spring MVC Project


This will generate a nice little hello world MVC app for you to get an idea of how it should be done.
