Hi currently this Java retrieves elements from a .json file. These elements create a photo gallery developed with JQuery. Requiments: Tomcat 9 and Java 8, PostgreSQL 10 1) EXTRACT FROM POSTGRESQL ***************************************** I want Java to query PostgreSQL and get the elements to create the gallery directly from PostgreSQL. The PostgreSQL table must be called "Contents" and must have 3 fields, the first "ID" (Serial) the second "MediaResult" (field type Json) and status (int) default is 0 Every single image must correspond to a line with relative ID. The Java file that gets the .json file is as follows (see part of the code), Therefore, each section of similar Json code will be a different image and must therefore be saved in a line of the dedicated PostgreSQL (table) and with its unique ID for each image. PS. To be clear this is the code Json related to an image in the gallery: { "title" : "Azuki bean", "description" : "Swiss chard pumpkin bunya nuts maize plantain aubergine napa cabbage soko coriander sweet pepper water spinach winter purslane shallot tigernut lentil [login to view URL] chard pumpkin bunya nuts maize plantain aubergine napa cabbage.", "thumbnail" : ["images/small/[login to view URL]", "images/small/[login to view URL]", "images/small/[login to view URL]", "images/small/[login to view URL]", "images/small/[login to view URL]"], "large" : ["[login to view URL]", "images/large/[login to view URL]", "images/large/[login to view URL]", "images/large/[login to view URL]", "images/large/[login to view URL]"], "img_title" : ["jquery elastic grid 1 ", "jquery elastic grid 2", "jquery elastic grid 3", "jquery elastic grid 4", "jquery elastic grid 5"], "button_list" : [ { "title":"Demo", "url" : "[login to view URL]", "new_window" : true }, { "title":"Download", "url":"[login to view URL]", "new_window" : false} ], "tags" : ["Self Portrait"] } Summing up Java will have to get the results from PostgreSQL and no longer from the .json file 2) IMPORT FROM CSV ***************************************** I have a CSV with the following fields: DESCRIPTION | TITLE | THUMB | CATEGORY | URL I would like a Servlet requesting through the form to select the .CSV file and save the various fields in Json, with the format of part 1 (attached .json file). Then the fields will match as follows: DESCRIPTION = description TITLE = title THUMB = thumbnail (value is one or multiple, as in example) CATEGORY = tags (value is one or multiple, as in example) URL = is this part: { "title":"Demo", "url" : "[login to view URL]", "new_window" : true } 3) APPROVATION ***************************************** The third and last part consists in moderating the contents loaded by the CSV file. It must be a servlet that in sequence will show a preview of the image, the title and the url + 2 button 1. APPROVED = value 1 2. DECLINED = value 2 Now there is a small change to be made to Part 1 (EXTRACT FROM POSTGRESQL) They will only be extracted, and then the visible images with the value 1 (Approved) Each time you access the approval servlet, it will start displaying images with a value of 0, making sure that all images are moderated gradually. PS. Once an image is approved or declined, the servlet will show the next image Not moderate.

1) reading from PostgreSQL instead of JSON - looks clear. Looks like everything is considered. Estimate - less than 1 day. 2) import from CSV. Looks like everything is considered and clear. To be started on first day. Expected completion - morning of 2nd day. Planning to make first deployment then (by default all approved). 3) the approval. Looks like everything is considered and clear. Except the UI part. Makes sense to display pages of images and radio box vis statuses 0|1|2 New | Approved | Declined also makes sense to add optional text field to explain decline reason - 2nd day - deployed 3rd day morning. 4) feedback - possible changes - 3rd day
