Maven dependencies not being added to WEB-INF/lib

Looks like your "Deployment Assembly" is missing the Maven Dependencies being added to the packaging structure of your project. The way this should look is:

The way to add that in is:
- click on Add
- select Java Build Path Entries
- select Maven Dependencies
- Finish

That should add your Maven Dependencies into WEB-INF/lib. In case your project structure is not standard, you can also edit that path by double-clicking inside your Deploy Path column - in this case, on WEB-INF/lib.

Hope that helps.
