Work on this contract included the technologies of JBOSS, Java, J2EE, EJB, Tomcat, and Oracle. Project’s focus
was to upgrade from JBOSS 2.4 to 3.2.1 and to implement upgrade enhancements which included new
development.
Selected Projects: EConsult application
This is a production application that Idexx call centers use to provide services to Vet clinics
around the world. Calls from vets can included ECG for animal diagnostics and faxed
information to complete consults that are sent to Idexx consultants where they can view the

Tools, languages, and products used on this contract included JBOSS 3.2.1, Java, JDBC, EJB,
JBuilder 7, Optimiziet 5.5, Toad, and Oracle.
This contract had two phases, upgrade and enhancements.
The existing site was using JBOSS 2.4.1 and needed to be upgraded to JBOSS 3.2.1. Work
included in this phase was to configure JBOSS configuration files and to update build and run
scripts to work in the updated environment. Application changes were needed to run in 3.2.1
due to allowances that 2.4.1 allowed in contrast to the J2EE specs for EJB needed
modifications before the application would deploy and run in the upgraded version.
Enhancements included bug fixes, new development, and performance tuning.
New development was designed and coded to work outside of the current
applications framework. This framework was written in Java by a 3rd party
contractor and had memory, processing issues and forced non J2EE code
module design.
Java J2EE Contractor (March 2002 to February 2003)
Bridge-Line Technologies, Woburn, MA
This five month contract included two applications. A content management system and e-commerce application
was the focus. Technologies used were The system for this application is Iplanet Web server 6, SP1, Apache,
JBOSS, Tomcat4.0, MYSQL, Oracle 8i, SQLJ, JMS, and Java 1.3.
Selected Projects: E-Commerce website
Main task for this project entailed designing and coding. This website was to currently handle
smaller loads but be able to scale to thousands of hits a day. This application follows a
modified design of the older J2EE PetStore framework. Major Architecture pieces of this
application include a caching framework for catalog items, Cache updating for all registers
code(Observer pattern based), JMS clients that currently uses an IBM MQSERIES
implementation. Both EJB of Entity and Session were used to Spec 2.0. JBOSS-3.0
application server was used with bundled Tomcat 4.0.
Designed order path support for both front and back end use. Worked on integrating
promotions and calculations into both cart and Order use. Designed the rough draft database
schema used across the site. Front end design allows for 1 to n sites based on URL. Based on
the URL, the front end will dynamically change look/feel and display the product catalog.
Most of this site in its current use is maintained by an admin piece used for maintaining all data
used across the site from affiliates, promotions, shipping rules, and catalog management. This
piece of the site utilizes the same framework and a large percentage of existing objects. New
EJB objects were created for most of the order and catalog paths due to the need existing for
the e-commerce piece using other methods of design.
Content Management System
Developed and supporting a web based content management system (CMS) for internal use.
This application utilizes simple form based logon storing user roles in a session-based object.
This system is used for updating all content in their production application, which receives
published files from the CMS server. There are 2 pieces to this CMS. One is for uploading
files and the other is for editing live in the CMS site. ActivEdit technology was used for the
formatting and HTML source view for dynamic use. This produce used the DHTML
component shipped in IE 5.0. Users have the ability to surf the directory tree to find the
specific file to modify. Once a file is updated, it is moved to an approval stage. From approval
to Legal stage then to a publishing stage. Each time a user (edit, approval, legal, publish) takes
ownership, the file is locked in that process for that user until a process is completed, cancelled,
or rejected. A lock management thread maintains this consistency with the database. Files are
published using FTP to production servers.
Java J2EE Contractor (December 2001 to March 2002)
Request Engines, Brighton, MA
Current work is Updating older Web based application to J2EE standards for web-based framework. For n’tier
environments using Java technologies and Oracle 8i EIS layer. This work entails removing a tightly coupled
application from its existing framework to separate business logic from presentation logic. Additional daily tasks
were to code new functionality, bug fixes and provide QA support. The system for this application is Apache,
Tomcat4.0, Oracle 8i, SQLJ, and Java 1.3 The system for this application is Apache, Tomcat4.0, Oracle 8i, SQLJ,
and Java 1.3.
Selected Projects: Create new functionality/maintain existing
Main task for this project entailed designing and coded new functionality for the web based
property management software. Most current work centered on completing new areas to the

building. This system allowed tenants to individually enter any visitor that would visit and
allowed them some functionality beyond simple name entry.

guards desk area for allowing sign-in functionality, name lookup, and Badge printing.
Designed web based application to create dynamically formatted badges that could be printed
at the client site with just the addition of a thermal badge/label printer. No client side
development was needed.

existing framework/application to one that separated the business logic from the presentation
logic into a J2EE designed system to allow for scalability and product growth.
Java J2EE Contractor (September 2001 to November 2001)

Java to according to J2EE standards and used to run in either web or n’tier environments using Java technologies.
.
Selected Projects: Miscellaneous Projects
Completed creating a stripped down J2EE framework of the SUN, Pet Store implementation.
That implementation consisted of developing modifications to the design to remove coupling
of the application specific code from its original design. These changes allow for the
Framework to be void of application specific code that uses it. Along with these changes are
build scripts and a base implementation of code to show an implementation of the framework
from front to back end.
Created an Implementation of the Log4J from Jakarta project. This logger was created to
store class specific instances of the logger and used utility classes to read through the call
stack to derive the class it was thrown in and held as a singleton for use by other calls in that
class. This was created using a modified Flyweight pattern.
