Contents  Project Overview  Zimbra UI changes  JBoss Rules  Integrating UI with Rules Waleed Srikanth Rohit Manoj

team # 5 CSCI-6838 Fall 2007 UHCL  Participants ◦ Have different time schedules ◦ Live in different time zones  Meeting Organizer (convener) ◦ Need to keep track of participants replies ◦ Decide the best time for a meeting  Business ◦ Some participants attendance are mandatory ◦ Minimum percentage of attendees have to be met Problem

team # 5 CSCI-6838 Fall 2007 UHCL This project applies rule-based technologies to improve the face-to-face and virtual meetings scheduling process with participants who can be geographically distributed with busy schedules

 Add more rules to the existing set of rules that are time and business driven  Provide intelligent feed back to Meeting organizer in the case a meeting can’t be scheduled  Provide real time manipulating capabilities to the meeting organizer for changing the meeting constraints:  Minimum attendance percentage  Attendance of all mandatory participants team # 5 CSCI-6838 Fall 2007 UHCL

 The project team will design and build the RoboComm system for a web-based platform using the following open source development tools:  ZIMBRA ◦ Supports , calendar and search facilities. ◦ UI using AJAXToolKit  100% Javascript UI  Based on Model View Controller (MVC)  JRules 4.0 for rule-based inferencing team # 5 CSCI-6838 Fall 2007 UHCL Implementation Constraints

 Pops-out a new dialog box for creating a calendar  Unchecks previous calendars and only selects the new calendar  A new appointment is directly created without showing a dialog box having meeting name as subject  A meeting can not be created by selecting two calendars at a time. This condition is notified by giving an error message team # 5 CSCI-6838 Fall 2007 UHCL

 Create a new “Reply Option” menu button and place it on the tool bar  Create a new view (ZmCalReplyViewMenu.js) for the “Reply Option”  Redirect to the reply form “Meeting.jsp” which contains meeting requests team # 5 CSCI-6838 Fall 2007 UHCL

 Fixed a problem while dragging an appointment (changing the time)  A new option on right click on an appointment to suggest new timings.  The view of “New Meeting Proposal” is a duplicate of “Week View” team # 5 CSCI-6838 Fall 2007 UHCL Other UI changes

 Firebug: ◦ Javascript debugging on the Client Side  JPDA (Java Platform Debugger Architecture) ◦ Remote (Server Side) Java debugging ◦ Debugs JSP/servlets with breakpoints team # 5 CSCI-6838 Fall 2007 UHCL

 Learnt about Zimbra, JBoss and how they work.  Learnt the MVC architecture for software design Challenges  Difficulty in modifying an implementation by others.  No code documentation for Zimbra team # 5 CSCI-6838 Fall 2007 UHCL

 Describe the operations, definitions and constraints that apply to achieve some desired goal  This is a software system that helps manage and fire the rules team # 5 CSCI-6838 Fall 2007 UHCL Rules and Rules Engine

team # 5 CSCI-6838 Fall 2007 UHCL Rules Engine Architecture

(these are bootstrap rules)  1) Weekday and weekend for a particular meeting based rule  2) Office hours for meeting time based rule team # 5 CSCI-6838 Fall 2007 UHCL

(when invitees send back reply)  3) Possibility of a meeting time by calculating threshold based rule  4) Mandatory and optional members for all meeting based rule team # 5 CSCI-6838 Fall 2007 UHCL

 Team work  Time management  Knowledge of JBoss rules and its importance  Working on Zimbra, Javascript team # 5 CSCI-6838 Fall 2007 UHCL

 Rules were developed independently from the web interface  Also, dynamically firing the rules after changing the facts will result in dynamic output team # 5 CSCI-6838 Fall 2007 UHCL Integration of JBoss Rules with Web Interface

team # 5 CSCI-6838 Fall 2007 UHCL Meeting Tool Form

team # 5 CSCI-6838 Fall 2007 UHCL

Data Used for Meeting Tool Analysis  All data about a particular meeting is captured to analyze the possibility of a meeting in accordance to meeting constraints  For example: Reply(Invitee, reply)

 Meeting Deadlines  Working as part of a Team  JBoss Rules  JSP and Servlets team # 5 CSCI-6838 Fall 2007 UHCL

 Installing Zimbra  Create Environment to Work on the JBoss Rules 4.0  Conflict using JDK 5 and JDK 6 with Tomcat 5.5 team # 5 CSCI-6838 Fall 2007 UHCL

Project Outcomes  Simplifying the meeting scheduling process  Flexibility for the participants to choose their best time or even suggest new time team # 5 CSCI-6838 Fall 2007 UHCL
