Could not find file commons-beanutils.jar to copy

I'm doing project using JSF, Hibernate, and Spring. Because I'm a newbie, I try to follow tutorial and download it. here is the link http://ift.tt/1HJRjR8 Now, I have the problem to run it. I get an error

D:\netbeans_project\LinkedLinks_Part2_SpringJSF\LinkedLinks\nbproject\build-impl.xml:1037: Warning: Could not find file D:\netbeans_project\LinkedLinks_Part2_SpringJSF\LinkedLinks\lib\jsf12\commons-beanutils.jar to copy.

Whereas, I put the jar in lib folder and in jsf12 (I make it manually). How to solve this problem so I can run it? Thank you. Your answer is very appreciated.
