What am I doing wrong? name and index set to boom.

Answer 1

Found the problem! context.xml should be in a folder labeled as resource ! And not just in a regular folder.

Answer 2

Check that the PNV constructor takes the three parameters in the given order, i.e. it looks like:

public PNV(FamilyPNV familypnv, NamePNV namepnv, PatronymicPNV patronymicpnv)

Answer 3

Learn to read the error trace. Here is everything:

Could not resolve matching constructor (hint: specify index/type/name arguments for simple parameters to avoid type ambiguities)
