Introduction

The aims of the assignment are:
• To implement web services for making available resources regarding a collection of recipes.
The recipes are those that you have worked with in assignment 1.
Using Java Reflection and Servlet API
• To apply the relevant validation strategies to the grocery, using the Validation Framework
we built in Lab 07.

The following are provided in the recipeWS directory (of the zip file)
• The jar files for JSON conversion and MySQL driver (in directory lib)
• The Java files for validation (in directory validate) some of them need to be
completed.
• CreateRecipeDatabase.sql
You can adapt this file to your own need. However, the table name must be recipe, and the
structure of this table must be exactly the same as that shown in the SQL script.
• The class Recipe.java
• The class RecipeDSC.java
• The class Helper with methods for JSON conversions
