In this lab, your initial focus will be on understanding various file formats, such as XML$,$ JSON, and CSV$.$ This involves understanding their structures and how they represent data.

Following this, you will proceed to create endpoints for a specific resource within your web service. These endpoints will be designed to serve the resource using three different file format representations, allowing clients to interact with the data in XML$,$ JSON, or CSV$.$

The entire process, from handling file formats to exposing the resource through endpoints, will be facilitated by the GlassFish server, which serves as the hosting environment for your web service.

Prerequisites

Ensure your GlassFish setup is functional, as this lab is a continuation from Lab $2.$

Lab Work

Part $1-$ File Creation

Given the dataset below represented in a tabular format, your task is to transform it into other file formats.

name id gpa

Ryan Gosling $1000000004\mathrm{.}3$

Keanu Reeves $1000000012\mathrm{.}9$

Richard Dean Anderson $1000000022\mathrm{.}7$

Brad Pitt $1000000033\mathrm{.}9$

Ed Norton $1000000042\mathrm{.}2$

Helena Bonham Carter $1000000052\mathrm{.}0$

Convert the data above into the following formats:

JSON

XML

CSV

Name each file students $($e$.$g$.,$ students.json$)$ and place them within src$/$main$/$resources$/.$

For the purpose of autograding, follow these formatting guidelines for each file type:

For all $3$ formats:

Fields for each record should be lowercase $($e$.$g$.,$ name and not NAME$)$

Fields should be ordered as: name, id$,$ gpa

Records should be sorted by the value of id from least to greatest

For JSON:

All the records should be stored in an array named students

Each record should be a JSON object with following fields and value types:

name is a string

id and gpa are numbers

For XML:

The parent element should be called students

Each record should be called student

Each field in a record $($i$.$e$.,$ name, id and gpa$)$ should have its own tag $($e$.$g$.,)$

Include an XML header at the beginning of the file with following attributes:

version: $1\mathrm{.}0$

encoding: utf$-8$

For CSV:

Header should be copied from the table above

Delimiter should be a comma
