Java EE samples are in three categories - Web Services, Java EE and Maven. It is somehow confusing that new Java EE 7 are all Maven ones, some of them demonstrates web services and all are in Java EE category. Please, consider moving them to proper categories or make a different category set.
Agree, I would say we should try to follow the official GF folder structure, delete Web Service and Maven folders and move all samples to the Java EE folder with several sub-folders (CDI, Web Socket, Servlet, Concurrency etc.) Targeting to NB 7.4
