My Computing Environment




Dell PC running Windows XP Pro SP2
All Java written using latest version of Eclipse
IM used to communicate with coworkers from
both offices, along with e-mail, conference calls,
etc
Linux and Windows servers
Computing Environment (cont'd)

Subversion


Scarab


Used as a server to control all source code. Developers
can check out and commit changes to the source code
and Subversion keeps track of version.
Issue tracking system where developers can submit
bugs and be assigned to fix bugs. Also used to request
changes in software, etc.
Maven

Powerful tool used to build projects and keep code
organized.
How To Work on a Project

First, check the project out of Subversion




Step into that project in your command line


Create a directory for the project on your machine
Open a command line to that directory
Run “svn co https://URL/proj-location proj-name”
Run “mvn eclipse:eclipse” to have Maven build the
project specifically for Eclipse.
Work on project in Eclipse
Working on a Project (cont'd)

Commit your saved changes back to the
Subversion server

Using TortoiseSVN


Can commit to the server straight from Windows Explorer
Using Eclipse

Can commit to the server straight from Eclipse using the
Subclipse plug-in

User Administration Project


One of my first and largest tasks was to upgrade
the User Administration project (UAdmin).
UAdmin



Modular
Easily integrated
Uses


Authentication
Storing user data
UAdmin (cont'd)

UAdmin was only able to deal with user name,
password and email address for users


This information had to be stored in a database
One of my tasks was to make UAdmin contain
more user information, including addresses, phone
numbers, instant message information, and even
themes

For this, a new database had to be designed
UAdmin
To accommodate the new data we decided to design
a new Data Access Object (DAO)
A DAO is the layer that sits in between the client
and the database and acts as the line of
communication
UAdmin Database
UAdmin Data Model
Next, we had to create the Plain Old Java Objects
(POJOs) that would match the database
UAdmin Persistence Method

The persist(user) method needs to control all of the
action on the object by deciding what action to
perform




Add
Change
Delete
When the client application attempts to
add/change/delete an object, only the persist
method needs to be called
How does the persist method
know?
if client object does not exist in database
create(object)
else if client object is exactly equal to database object
return object
else if client base object is equivalent to database object
recursively persist child objects
else if client object has been deleted
delete from database
UAdmin Tasks

Also, I created a new authentication procedure

Java Authentication and Authorization Service (JAAS).


Users can now login using their database user name and
password or using their MobilVox network user name and
password
Using JAAS allows us to create login
configurations


Database login
Network login
UAdmin Tasks

Finally, theme support was added

Ability for client application to allow users to select
themes




Colors
Fonts
Sizes
Etc
Summary

The internship experience in invaluable





Real world experience
Very nice paychecks
Great learning experience
Learn things you simply can't learn in the
classroom
Recommended for all computer science majors
Internship Relation to IUP

Courses that were extremely useful




Courses I wish I could've taken first


COSC 341 (Database)
COSC 210/310 (Concepts using JAVA)
COSC 110 (Basics of programming using C++)
COSC 319
Material I feel should be added to curriculum


More information on development environments like
Eclipse and tools like SubVersion
Information on building projects with tools like Maven
