Question

I need your help and advice. This is my first project in jersey. I don't know much about this topic. I'm still learning. I created my school project. But I have some problems on the web service side. Firstly I should explain my project. I have got 3 tables in my database. Movie,User,Ratings
Here my Movie table columns. I will ask you some points about Description column of the Movie table. I will use these methods to these columns.
Movie= Description (get,put,post and delete) I have to use all methods in this page.
             movieTitle (get)
             pictureURL (get,put)
             generalRating (get,post)

I built my Description page. But I'm not sure if its working or not .(My database is not ready to check them). Here is my page. I wrote this page, looking at the example pages. Can u help me to find the problems and errors. I just want to do simple methods get(just reading data), post(update existing data), put(create new data), delete(delete specific data) these things.What should I do now, is my code okay or do you have alternative advice? :( I need your help guys ty

I just want to do simple methods get(just reading data), post(update existing data), put(create new data), delete(delete specific data) these things

POST should be used to create resources and PUT should be used to update resources.

Your class already has webservice path /Movie/Description, so there is no need to repeat word Description in the methods.

Also, I would recommend keep path names in lower case e.g. /movie/description
