Explanation of Todays Hands-On Presentation

• What is trial by fire?

Its how the real world works!

• Youre given a project to work on.
• Once you complete the project
• Youre smarter

  telling you
• Youve built character as well as experience
• After completing the project, well present what
  we learned

Overview of Framework Well Build
CAMPAIGN FULFILLMENT
A Tool For Getting the Right Information To The
Right People

• Back-End Engine for processing data and sending
  information to people
• XML-based
• Database Connectivity (MS Access in this version,
  CSV in future)
• Email-delivery capability (Postal mail and fax in
  Version 2.0)
• Web Interface to Campaign Fulfillment Engine

7
Process User Interface

• User submits Job Request as an XML Document

8
Process Delegation to Business Logic

• Servlet creates a Job Manager to handle the job

9
Process Controller initiates Job Processing

• Job Manager creates a relationship to a XML
  Document Manager and passes the document

XML Doc Manager
XML Doc
10
Process Creation of Components from XML

• During operation, the XML Document Manager will
  create appropriate component objects from the XML
  Definition

11
Process Data Retrieval

• Job Manager utilizes the XML Doc Manager and the
  DS Manager to build a list of records

Record List
1 Record Field List
12
Process Setup the Message Handler

• The XML Doc Manager creates a Message Manager,
• which holds the message to send and can replace
  parameters in the message if needed.

13
Process Setup the Delivery Mechanism

• The XML Document Manager creates a Delivery
  Manager, which can send the message to your
  intended audience.

14
Process Campaign Fulfillment

• For each record to be sent, the Job Manager tells
  the Message Manager to format the message and
  tells the Delivery Manager to send it.

15
Your Mission, Should You Choose To Accept It

• Servlet Group creates web interface using Tomcat
• XML Group creates objects from XML
• DB Group retrieves data from Access DB
• Message Group manages and builds the message
• Delivery Group sends email through JavaMail

But its not as hard as you might think!
