Get started with Groovy and Grails in 90 Minutes

  • December 14, 2010 · 6:30 PM
  • BlackRock

Most of you have heard of
Groovy (a JVM-based OOP language) and
Grails (a web framework sitting on top of
Spring and
Hibernate), but have you actually seen it in action? For our December 14th event, we are extremely fortunate to have Jeff Brown (committer on GG team) come and show us how to
Build Twitter With Grails In 90 Minutes. "This live coding session will demonstrate how the basics of Twitter can be built using Grails in less than 90 minutes. The fast paced and code-driven presentation will build a Twitter-like application from scratch using Grails and its rapid application development capability. By bringing together Spring, JMS and Java persistence techniques, Jeff will provide advanced tips and techniques for constructing Grails applications that can be deployed on to the Java EE platform. This session goes well beyond building simple CRUD applications with Grails." Time-permitting, Jeff will also give us a short overview of GORM, a super-powerful ORM tool that makes ORM simple by leveraging the flexibility and expressiveness of a dynamic language like Groovy, as well as introduce us to the idea of metaprogramming with Groovy. By the end of the evening you should feel excited and empowered enough to try to use Groovy and Grails for your own projects. You don't want to miss this one. Note that this event will be hosted at Black-Rock, which generously offered to provide sandwiches, salad, desert, and sodas. As before we'll be giving away prizes from our many sponsors. About Jeff Brown: For over 10 years Jeff has been involved in designing and building object oriented systems. Jeff currently teaches a number of Java and object oriented training courses in addition to doing consulting and mentoring work for industries including Aerospace, Financial and Medical. Areas of expertise include Java, agile web development with Groovy and Grails, distributed computing, object database systems, object oriented analysis and design and agile development. Jeff became a Grails committer in 2006 and continues to be an active contributor. Blog at

    Folks, I watched the recording of this session in UGatGoogle YouTube channel - extremely impressive. Is this demo code out there share somewhere?

    The event was great. It was a short, but it was so informative and I felt I had everything I needed to get started.

    Really cool! The technology is pretty slick, the presentation was right to the point, and Jeff was absolutely amazing. Great turnout (given the weather) and fantastic food/venue. Big thanks goes out to Spring Source and BlackRock!

    Very helpful intro to Groovy and Grails. I am new to both, and this MeetUp was really worth my time. Thanks for putting it together!

    Excellent fast-paced code presentation. Excellent venue at Blackrock, 400 Howard. Code was easy to read on the large bright screen hanging from the ceiling. Groovy saves a lot of time in developing a new application. Groovy automatically sets up a set of folders containing elements of your new app. With a few exceptions, Java code can be simply pasted into your new Groovy app.

    Jeff has advised the following:

    Any JDK 1.5 or greater.

    I will be using Grails 1.3.5. Anything in the 1.3.x chain should be fine.

    If I end up doing anything directly in Groovy (as opposed to Groovy work within the context of a Grails, which bundles its own Groovy) I will use Groovy 1.7.5. Anything in the 1.7.x chain would probably be fine.

    I was wondering if Jeff could let us know which software versions to load before the live coding session, if we want to follow along? I'm new to Spring and haven't used Groovy/Grails before. It may help save time before the session starts. Thanks!
