Spring MVC - view problem

I'm new to Spring MVC, and there's something I don't get:

I'm using a simple InternalResourceViewResolver. prefix is "/WEB-INF/jsp/" and suffix is ".jsp"
My Controller returns a ModelAndView whose View name is "home", so the Dispatcher should look for the file "/WEB-INF/jsp/home.jsp"

If the file does not exist, an error occurs. Ok.
But if the file exists, nothing is printed out. The file "home.jsp" only contains a greeting message, but I have a blank page.

It worked with suffix set to ".html"
Would this be a container related problem ? I'm using Tomcat 5.5.

Any clues ?
Thanks.

Ok, I've found the problem.
I had jsp-api.jar and servlet-api.jar in my lib directory, probably conflicting with Tomcat's own jars. Removing those intruders solved the problem.
