What my coding style looks like.
The application expects a MySQL Database Server running on the local machine, with user=root, password=vertrigo, database schema=university.
Otherwise, please set up the datasource in \src\main\webapp\WEB-INF\uni-persistence.xml and the Maven dependency in pom.xml.
The application was tested on Apache Tomcat 6.0.39 and VertigoServ 2.30.
