Hi all,

i'm a newbie in spring and i was following the Developing a Spring Framework MVC application step-by-step tutorial to learn how spring works.

When i get to part2, i am getting an error when try to open the webapp in the browser.
I've got the following exception in :

I'm using jdk6u7 with spring 2.5.5 and tomcat 6.0.18.
I would appreciate if someone could help me.


Thank you

When I get a NoClassDefFound error like this it generally means I'm either missing one of the Jar files I need, or I've put my Jar files in the wrong place and Tomcat isn't finding them. The particular class that Tomcat isn't finding in your case is in the spring-core.jar file, so make sure you have that one and it's in the right location, registered with your container, etc.

Hi,

i know that it can't find the jar, but i think that the jar files are in the right place.
I've put spring.jar, in springapp/war/web-inf/lib, as it is suggested in the tutorial.
I've also put spring-core.jar just to make sure, and still doesn't work.
I think that spring-core.jar isn't needed because it's included in spring.jar, right?

I have no idea why this don't work.

Thank you

Another thing,

I've deployed the application in glassfish and it works ok.
So, tomcat is having a problem in finding the jar file.

Can anyone help me?
I will use glassfish for now, but i would like to figure out why it doesn't work with tomcat.

thank you
