I think it would be helpful if I give you my .war file. Then you can see
that the web-inf paths have different casings. You can download it from:

Our IT departments says that when the .war file is deployed, everything is
stored in WEB-INF upper-case (so there is no web-inf lower case).
I hope you know a solution to fix the search error. If you need more
information, please let me know.
