Objectives
Implement an e-mail client service which
unifies service provided by different email
services.
 Allow the user to provide the list of email
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 email management it easy for users of multiple email
accounts.

Project undertaken to cater to online e-mail providers’ clients with
multiple e-mail 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
email accounts using which the One Stop Mail Service logs into
those email 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.
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.
