Developing EJB applications with Eclipse and using Subversion for version tracking

Martin Heinemann - CRP Henri Tudor

Dr. Georges Schütz - CRP Henri Tudor

During the first day the tutorial will give a glance at the concept and development of “Enterprise Java Bean” (EJB) applications by using the “Eclipse” development environment. The second day is reserved for some “Eclipse extensions” and will focus on the “Subversion” version tracking system. Today, the demand of distributed multi-tier applications is growing constantly. Application's life-cycle is decreasing, therefore there is a need of flexible concepts that allows to adapt the products to the market requirements. Enterprise Java Beans (EJB) offers a concept to create small reusable software components that are used to create large business applications. It comes a long with transaction-, naming-, and security services that are a must-have for such applications. Developing such applications requires an environment suitable to handle the complexity and support the team oriented work. The first tutorial day will give a small introduction to the underlying EJB concepts and programming techniques. Some of the topics are Session Beans and Entities. What does “deployment” mean and what does the word “container” stands for. This theoretical part is followed by an introduction to the Integrated Development Environment “Eclipse” with the main focus on how to use it to develop Java applications accompanied by a small sample application that makes use of the EJB 3.0 concepts and the JBoss application server.

The second Day will focus on version management, a topic not only helpful and commonly used in FOSS development. This tutorial will introduce “subversion” a more and more used alternative of CVS for version management proposing the missing CVS features and even more. Version management is not only a topic in software development also other fields like documentation, web content or other work done in coauthoring can benefit from this. Even for a single person version management can be of grate interest. The tutorial will shortly introduce the field of version management. First subversion will be introduced as a local and server based environment. This part, focus mainly on administrative tasks like setting up the system and the repositories, managing user accounts and alike. In the second part the subversion client and the daily work with repositories will be focused. Key-words are check out, commit, compare, tagging, branching, merging … As client we will use an eclipse extension in order to have the version management integrated in the development environment. As an example we will use the simple EJB application. Two teams will practice some common situations during team development and experience the power of version management. Finally if there is still time left the topic of decentralized version control system based on subversion using SVK will be aborted.

Prerequisites

The attendees should have more than basic knowledge in using an operating system. Linux knowledge is not required as eclipse, EJB and subversion also runs on other OS then Linux but it will be very helpful as the tutorial will be based on Linux as OS. The attendees should also have basic knowledge of databases and the Java programming language.

About the speakers

Georges Schutz works since 2004 at the Centre de Recherche Public Henri Tudor, where he was before as a PhD Student in computer science. He is using the GNU-Tools and the Linux system since 1991. The main field of interested apart from free and open-source software is the domain of data analysis, especially focusing time series, based on advanced methods like neural networks, and other data mining approaches.

Martin Heinemann works since 2006 at the Centre de Recherche Henri Tudor. After finishing his diploma thesis about Enterprise Java Beans topics he started working on several EJB Java projects at the Centre. Since 2001 he is using GNU/Linux especially Debian and later on the Ubuntu distribution for his daily work.

Secure Linux Mail Server

Christian Mock - VIBE!AT

This tutorial consists in configuring a mail server based on Postfix. In the first, more theoretical part, the architecture and the different configuration files of the Postfix system will be explained. During the practical part, the attendees will setup a mail server that handles different domains. Then, the server will be extended  in a way to be able to scan for viruses.
In the second part of the tutorial, we will go into details how to protect your mail server and mails from spam.

Prerequisites

Participants should know how to use the Linux command line interface and a text editor, and have good knowledge of the TCP/IP protocol.

BOINC: An approach to grid computing.

Marc Seil - CRP Henri Tudor

The processing demand is growing in every domain. In order to satisfy this need different solutions are imaginable. One of the most interesting approaches, is to share empty available resources and group them to a distributed computing environment. In this workshop the “Berkeley Open Infrastructure for Network Computing” is focused, as an approach to distributed grid computing. The BOINC infrastructure allows to merge the idle CPU cycles of a heterogeneous computer environment (Office PC, Server, Workstations, ..) in a grid. Often this solution it is referred as internet computing. In this tutorial the attendee will get basic BOINC infrastructure knowledge. The backbone tools like: apache, mysql, php will be installed and configured. Based on this set up the BOINC services will be attached. The course will follow up with a BOINC project and first work unit creation. After the server side installation is finished, the attendees will be able to populate their grids with processing nodes. The workshop will be finalised through a real running BOINC grid. The workshop is a more detailed walk through of the Linux Magazine article “Building distributed applications with BOINC” (Issue 71) on a UBUNTU Linux system.

Prerequisites

The attendees should have more then basic knowledge in using an operating system. Basic mysql, sql knowledge could be use full. The commands make, ./configure, gcc and the console should not cause panic.
