Accomplishments

Obtained Access to Server hardware Selected subversion system Selected J2EE Webserver – Geronimo Modeled Object Oriented Structure of

Application Wrote short SQL scripts for application

deployment Obtained Access to MySQL on server

Server

Got with Guy, obtained access to server (permission from Guy, login, password)

Logged into server successfully Server is entirely Linux based (no GUI) Server currently has some PHP code already in

its HTML directory (meaning someone is using it)

Do not have permission to visit site (eecsgrades.vuse.vanderbilt.edu)

Server Todo

What can we / can we not do on our server (Will have to ask guy how far we can go in terms of installing software)

Can we install our subversion system on the server as well?

FTP? Risks: Linux command line (its not fun but

Jared knows it), dedicated hosting?

Webserver

Geronimo Java's fully J2EE 5 compatible web server

solution Easy to use Comes with console web application to

manage mySQL configuration, application EARs, ports

May not be the best, can be cumbersome as it is very out of box

May have speed issues, we shall see

Strongest Advantage of Geronimo

Can compile your code using Eclipse or Netbeans into EAR (Enterprise Archive file)

This is an easily deployed bundle containing your entire web APPLICATION

Can go online to Geronimo console and simply redeploy your EAR on each build

Can connect databases to Geronimo (to use out-of-box J2EE database configuration)

Object Oriented Model

We discussed this last time but... Model – View – Controller

Controller – web.xml and Controller.java will forward requests based on POST data and URL and call model classes

Model classes will inherit from base class – perform action and forward data to view

View will be JSP with tags in it to take data from model object passed to page

MVC Diagram

Controller

Web.xml

FwJSPServe.java

Model Class MySQL Database

Correspond ing v iew .JSP

MySQL Scripts

Paul, the mastermind behind our data dictionary, has constructed short SQL scripts for our mySQL database

Currently create the required tables R&D to be performed to determine where

relationships may be necessary, indexing, primary/secondary keys, etc

Potential Risks

Deployment of Geronimo to Server (medium) Getting permission from Guy to do a lot of what

we are hoping to do (medium) Successful implementation of SVN on server

(low) Linux command line only? (low) Deployment of EAR to actual VUSE web server

(medium but a long time from now)

Next Steps

Install Geronimo on server and test Deploy a Hello World EAR on geronimo server

Hello World to request data from database/write to database

SVN on server Meet with David Lynn to discuss if an EAR is a

good means of proving him our final code Code, code, code Prepare for PDR (discussion on what a good

group will have...)
