I am working on a Spring with Hibernate project that also uses Maven. I am trying to make a page that has a form to capture search information as well as displaying the result. I have created the dispatcher-servlet, web.xml, controller, model, and view but when I try to run the project on the server I get the following 500 error:
Servlet.init() for servlet dispatcher threw exception (stacktrace and files below).
I am a little confused because I am following a tutorial and I believe I have all of my dependencies correct. I have taken a look at the stack trace and from what I have read, there seems to be a versioning problem. I have tried changing my versions in the pom.xml file but haven't had any luck. I also checked the WEB-INF/lib folder and I have hibernate-core as well as the other required jars, so I think the pom.xml is configured correctly.
From what I understand about Spring, the dispatcher-servlet should be injecting the sessionFactory bean, but it doesn't seem to be working correctly. I think if I can get past the sessionFactory problem, I would be able to move on.
pom.xml (I am not quite sure if my depencies are correct.)

I am fairly new to Spring, Hibernate and Maven. So I apologize if this seems trivial.
This is only part of the stack trace. I'm not very good at determining what the problem is from looking at the stack trace so if there is some pointers that you can give me like what part of it to look at first or if there are any areas that I will be able to ignore, that would be very helpful as well.

You're missing some spring dependencies. Try with these (add the correct version tag to the dependencies):
