Greach 2014, The Groovy Spanish Conf 28/March, Madrid, Spain http://greach.es Follow us on twitter http://twitter.com/greach_es James Page will tell the story of how he and Sabrina Mach built Webnographer on the back of a Grails Application. The application is a UX Testing suite that has been used by the likes of British Telecom, Electrolux, Vodafone, and numerous over companies. Webnographer had early success and without the performance of Groovy and Grails would not be where they are today. The application went very quickly to a situation where the application was being used by several million users a month on minimal hardware. James' presentation will go into how the simplicity of Groovy and Grails has allowed them to expand without needing outside investment. He will give details of their development work flows, and also how they deploy. A key advantage of Groovy is that it is based on Java and that it is easy to learn. James will detail how he on boarded developers to the Groovy Environment. The talk will help anybody, who needs a case study to justify using Groovy and Grails. James Page Webnographer James Page is the co-founder of Webnographer, the remote usability company. James started off as a programmer, but soon realised that, to see what he has created was becoming a reality, he would have to be entrepreneur as well. James has been involved in a number of start ups, including Eidos (who went on to launch Tomb Raider), and Deckchair.com with Bob Geldof. He is passionate about making software less frustrating and easier to use.

Greach 2014, The Groovy Spanish Conf 28/March, Madrid, Spain http://greach.es Follow us on twitter http://twitter.com/greach_es Slides in: http://greach.es/speakers/alonso-torres-understanding-gorm/ UNDERSTANDING GORM GORM is one of the keys for the success of Grails, but for a Grails beginner some concepts may be a bit confusing. Even for a long time developer there can be some missconceptions due to the abstractions layers of the framework. In this talk I'll try to cover some of the basics of GORM, Hibernate and how to interact with transactions and sessions. I'll show some of the problems that I had starting with the Grails framework and how I think they are best solved. Some other topics that I'll go over are the interaction with GPars, transactionality inside tests and the differences between "session" and "transaction".
