I'm trying to do an HTTP GET taking a parameter from the URL and then search into 2 file and send back the informations to the user. I've Tried the Java code into a Main Test without any server or request, and it works without any problem and also the taking of parameters from the URL works. There are other classes made because the file is a Json Array of Objects.
Error Message
HTTP Status 500 – Internal Server Error
Type Exception Report
Message org.glassfish.jersey.server.ContainerException: java.io.FileNotFoundException: \AutoCompilersz\src\net\codejava\ws\italy_cap.json (Impossibile trovare il percorso specificato)

I solved it like this:
try (InputStream is = getClass().getResourceAsStream("/resource/italy_cap.json")) {
InputStreamReader isr = new InputStreamReader(is);
JsonReader reader=new JsonReader(isr);
Gson g = new Gson();
p=g.fromJson(reader, Foglio1.class);
