One Stop Mail Service Bhattacharya, Tonmoy, Bhattacharya, Tonmoy, Hariharan, Rama Krishnan, MS in Engineering Science, University at Buffalo

Objectives  Implement an client service which unifies service provided by different services.  Allow the user to provide the list of accounts that needs to be managed.  Provide an interface for the user to access his accounts and view the mails in each account.  Provide basic authentication for user login.  Maintain a relational database service to maintain information pertaining to different users.

Project Explanation  Mash-up SOA application that unifies the user’s mail accounts from several online mail providers  Makes management it easy for users of multiple accounts.  Project undertaken to cater to online providers’ clients with multiple accounts across different services.  Project will ensure user operate on their accounts in a more organized, efficient and speedy manner – from a single application.  Project does so by storing the users log-in information to various accounts using which the One Stop Mail Service logs into those accounts.

Enterprise Design

Architectural Design

Technology Used  Java EE 5  Glassfish 9.1  Eclipse IDE

Design Choices  Used Java Web Services to create the service and client. Java annotations were used to map java methods to WSDL and conversely call service functions from them.  Java EE 5 technology was used throughout to enable the development of the project.  Web services deployed in Glassfish Application server.  Eclipse IDE was used for development of the project.  JSP was used in creation of the client web pages.

Implementation Details (Yahoo!)  Register the application with Yahoo - Provide URL of the application & get an application id.  Browser based user authentication (BBA) - One Stop Mail application redirects user to Yahoo login page for getting user’s login details. On authorizing, Yahoo! returns a token to the application using which the user’s mails can be retrieved.  Need for an external static ID. - Application registration and BBA made an external static IP necessary. Yahoo mail was not implemented as part of the One Stop Mail service because of this reason. - Application registration and BBA made an external static IP necessary. Yahoo mail was not implemented as part of the One Stop Mail service because of this reason.

Implementation Details (Gmail)  Google provides only Atom feeds for Gmail.  Made use of Google Data APIs to retrieve the Gmail atom feeds.  A new web service for accessing Gmail was created using this API.  One Stop Mail Service takes the user inputs for two mail accounts and invokes this Web Service twice to retrieve the mails of both ids.  Gmail allows only feed reading and so other operations like deleting, composing, moving a mail, etc is not possible.

DEMO

Why This is an SOA  Client invokes one stop mail service which invokes Gmail Web Services thus making the application an SOA.  The resolution of static external IP issue for and inclusion of yahoo mail checking facility will make One Stop Mail a full-fledged process enabled SOA.

Results  User’s Multiple Accounts Accessible from One Stop Mail  User Account Login Dynamically acquired.  Application is designed to enable easy future improvements.
