Online cooperation learning environment : a thesis presented in partial fulfillment of the requirements for the degree of Master of Science in Computer Science at Massey University, Albany, New Zealand
This project aims to create an online cooperation learning environment for students who study the same paper. Firstly, the whole class will be divided into several tutorial peer groups. One tutorial group includes five to seven students. The students can discuss with each other in the same study group, which is assigned by the lecturer. This is achieved via an online cooperation learning environment application (OCLE), which consists of a web based J2EE application and a peer to peer (P2P) java application, cooperative learning tool (CLT). It can reduce web server traffic significantly during online tutorial discussion time

Towards an aspect weaving BPEL engine
This position paper proposes the use of dynamic aspects and
the visitor design pattern to obtain a highly configurable and
extensible BPEL engine. Using these two techniques, the
core of this infrastructural software can be customised to
meet new requirements and add features such as debugging,
execution monitoring, or changing to another Web Service
selection policy. Additionally, it can easily be extended to
cope with customer-specific BPEL extensions. We propose
the use of dynamic aspects not only on the engine itself
but also on the workflow in order to tackle the problems of
Web Service hot deployment and hot fixes to long running
processes. In this way, composing aWeb Service "on-the-fly"
means weaving its choreography interface into the workflow
File Transfer Web Application
Aim is to develop a web application using java web framework.
Description: Develop a web application in 3 tier architecture involving user interface, controller and database. The user interface will be a web page hosted on a server. The web page consists of both static and dynamic content. All the data required for the application is stored in database tables. Controller accesses the data from the database and provides it to the user through user interface (web page). Web page: The webpage serves as user interface to the application. Web page is developed using Jsp, HTML, Java Script and Ajax. Controller: The controller serves as the communicating interface between web page and database. Controller serves the data to the user based on the user request. Controller is developed using Java 7, Java Servlets, and JDBC. Database: Database is used to store all the required data for the application. Database tables are designed according to requirement and developed using SQL. Server: Server is used to host the application. The developed web application is deployed onto server. Apache Tomcat is the application server for the application.
Environment: Java 7, HTML, Java Script, JDBC, Ajax, Apache Tomcat, Derby Database, SQL
