2 Hands-on Project A single running project to de developed along all the course sessions to help on consolidating the concepts presented on the lecture part and also to get hands-on familiarity with tools and technologies. Assignment The project above will be also the base of a group (2-3 participants) assignment to be started during course sessions and concluded after the course. Infrastructure Accounts: computer, CVS repositories, Wiki Software: Java, Eclipse, Tomcat, Axis 3 Project Video Library An application for a video library to support customers on the rental of copies of movies, about which it is provided actors and director information and also price category and genre. Directors: Chris Miller Raman Hui Actors: Mike Myers... Shrek (voice) Eddie Murphy... Donkey (voice) Cameron Diaz... Princess Fiona (voice) Antonio Banderas... Puss in Boots (voice) Julie Andrews... Queen Lillian (voice)... Genre: Animation / Adventure / Comedy / Family / Fantasy Price: not available 4 2

3 Project Video Library : requirements Every movie whose copies can be rented has to be entered into the database. The main actors as well as the director(s) must be set for the movie. It s also a requirement to assign a movie to a genre and a price category. Customers may rent copies of movies. Every rental can be uniquely identified by the combination of the customer s ID, the copy s ID and the date it was picked up. The fee is the result of a simple computation depending on the movie s price category and the number of days the copy was rented. 5 Project Video Library : information 6 3

4 Assignment Video Library Goal The main goal is to evolve an existing standalone application for a video library into a client-server application based on web services. Video Library (standalone) Video Library (server) web services Video Library (client) 7 Assignment Video Library Basic Tasks 1. Understand the given application code. 2. Familiarize yourself with a Web services framework, such as Apache Axis 1, or Apache Axis Build simple services for the tasks in the Main class of the application and test them using a Web Services client. 4. Design (macroflow) business processes for the application using BPEL (e.g. use the Eclipse BPEL designer: 5. Refactor your services and the application so that it works with the business processes that you ve designed, orchestrating them using simple Java code as a workflow engine. 6. Refactor again your services and the application so that it works using an existing BPEL engine, such as ActiveBPEL (works on top of Axis 1.4), Apache ODE (works on top of Axis 2) or JBOSS JBPM, as a workflow engine. 7. For recurring technical tasks you can optionally refactor the Java code in your services and build new services in order to expose technical microflow services which can be used by the macroflow services used by the BPEL engine. 8 4

5 Assignment Video Library Advanced Tasks (optionally choose one) 1. Integrate at least one external service in your application. Example: integrate the Yahoo search service or the Amazon web service to offer additional information for the movies. 2. Write a Web Services client on a different platform. For instance, write a.net client for your application. 3. Generalize your application code using the MDSD tool OpenArchitectureWare: That is, build EMF models for the models in your SOA and automate building the schematic recurring code. 9 Assignment Video Library Deliverables & Deadline Please send submit your solution to ademar.aguiar@fe.up.pt and zdun@infosys.tuwien.ac.at till 9th July. In the solution include: an ANT task with which your complete solution can be build ANT tasks for running all individual parts of your application a step-by-step installation instructions and how to run your solution (which configuration, application servers, frameworks) and a brief documentation for your solution. 10 5
