New CEJUG Open Source Project


As I have mentioned yesterday, I’m working on a new project, managed by the CEJUG community, which aims to develop a web application for managing Java User Groups. We put it into production in the first day of the decade, January 1st, 2011, and we made the source code freely available on our project.

The first goal we want to achieve is the definition of what is actually being a CEJUG member. Nowadays, we simply consider all those registered in our technical mailing as members. This simplicity is good for management purposes, but we lose lots of information because of that. We don’t know, for instance, for what reasons a member is leaving the group. Did we do something wrong? What can we do to get better and get members back into the boat? We also noticed that even non-technical people, as entrepreneurs, recruiters, and those who decided to unsubscribe because of too many messages, would like to keep in touch with the group, not necessarily going into technical discussions, but proposing other ways to help. Adopting a separate application to manage subscriptions would help us to collect more feedback and be more inclusive.

Developing our own solution can make data work in our favour and allow our sustained growth. Consequently, we are generating an additional source of knowledge for the community. This application is open source and everyone can run and see how CEJUG works. Beginners will have a solid source to start their studies on the development of Java web applications, experts can help with bug fixing, refactoring, and developing new features according to our issue tracking. Adopted design patterns may be subject of valuable and warming discussions in our community.

Of course the application was developed in Java ;-) We have the duty to write the software architecture document in the coming days, but we can already say in advance what we are using to develop and deploy the application. The presentation layer was developed in JSF 2.0, using the Primefaces component library; the business layer was implemented in EJB 3.1; the persistence layer was implemented in JPA 2.0; data is persisted in MySQL; and everything is running on Glassfish 3.0.1 Application Server. The current version was developed using Netbeans 6.9 due to its productivity when developing JEE applications. We rely on the container to manage security, database transactions, connection pools, and email sessions.

The next step is to document the application, add customisable features and internationalise it in order to spread its adoption by several other JUGs out there. We are looking for contributors and supporters to make this a successful open source project. We hope one day, we could promote interoperability between JUGs through this application, sharing mutual knowledge, events, effort on the growth of the Java platform and the Java community.

    I have translated in French your I will look further into it.
    Thanks for opensourcing the code.

  2. Hi Emmanuel,

    This is so kind of you! Thanks so much for you contribution. Can you send it to me or do you want to add it yourself? To do that, please join our project at and let me know your username. I will allow you to commit in the project. I also need your full name, JUG name and company to put you in the contributors sessions. Do you mind?

    This is awesome. I like the opportunity to be able to contribute to an opensource project that also helps me stay up to date with the Java EE technologies. I’ve been in Spring land for the last few years and would love to come up to speed with the Java EE 6 platform. This project seems like a good opportunity for it.

    My only gripe is this in on Subversion and not Git.

  4. Hi Sudhakar,

    Good you mentioned Git. We are actually moving to Git in the coming days. I will publish a post here explaining how to contribute to the project as soon as the Git repository becomes available.

    We are very happy for keeping you up-to-date. Thanks for your interest! Let’s keep in touch.

    I highly, highly, highly recommend git. It is the essence of OSS. Did I mention I recommend it? Git absolutely revived our project. Hopefully it will help sustain the progress of yours. Go for it!
