The main aim of this tutorial is to develop REST services for CRUD operation in MongoDB, this REST service is used in web application which contains Admin Login, Employee Registration, Home page where admin can view list of employees and also admin can update/delete details. This application has to be deployed in Amazon AWS. Mongo DB, Amazon AWS, Eclipse, JSP, HTML, Java, CSS, Tomcat
This application is mainly to perform CRUD operations in Mongo DB with REST Service. Application contains Login page where the Admin has to login with valid details. After login list of employees are fetched from Mongo DB and displayed on Home Screen. Admin can also add new employees by giving employee details. Apart from this admin can update the employee details and can delete the existing employee. This application is deployed in Amazon AWS with below WAR file .
Once the application is deployed successfully in AWS a link is generated. Through which any one can access to the application.
Amazon AWS Link: http://asesampleproject.cpmgzupmmd.us-west-2.elasticbeanstalk.com/
Once the link is access the user can see login page, where the admin has to login with valid email id and password as shown below. If the user has not entered any details then validation will thrown to user. Also validation will be thrown if user has not entered valid email id (Email Id doesn't contain '@'/'.')

Login page with valid details
Once the admin is logged in successfully, the admin can view employee details which are fetched from MongoDB. So initially the connection is made to MongoDB by specifying the respective Collection Name. (**Mongo URL:** mongodb://root:password@ds057386.mlab.com:57386/aseproject). If there are no details then null values are displayed in Home screen.
