2nd Semester Meeting 2 Matt Bernstein, Paul Capelli, Jared Segal January 22, 2008

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

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...)
