Last month, we launched mobile views for Secret Escapes, our little application written in Grails.

For this project, we chose to implement a set of mobile views on top of our existing Grails application using jQuery Mobile. In less than a month, we were able to implement and put live a set of views that simplified the user experience for our mobile users.

In this post, I will discuss some of the tools, challenges and design decisions that arose from making our existing Grails application more iPhone friendly. Continue reading

Migrating a Spring Application to Grails: Where do I put all my stuff?

As some of you might now, I started a new job with DMC Digital / Dealchecker. One of my first tasks was to migrate a pretty large Spring application ( ~650 beans, 120 domain objects ) into Grails.

One of the more daunting tasks is figuring out where to put all the Spring-related stuff into the Grails application structure. Here is a picture I made to help myself remember where all the bits and pieces fit. ( Think of it as chapter 1 of my upcoming and completely fictitious Head First Spring – Grails Migration book ).

BTW, DMC Digital is still looking for talented Grails developers

I’ve been playing with Grails and the Google App Engine for about a month. Overall, I’ve been very happy about the experience. There seem to be a few questions and misconceptions about the app engine and Grails, both on forums, blogs and the Grails mailing list. I thought I would put together a quick summary for those looking for more information about deploying on this platform. Continue reading
