Spicefactory – Part 2: Add Pimento to your Grails dish!
Posted by Maarten Winkels terribly early in the morning: December 11th, 2008
This second part on Spicefactory will delve into the details of writing a Grails plug-in for this framework. Be prepared to read a lot of code!
Spicefactory – Part 1: Spice IT up, with Parsley, Cinnamon and Pimento
Posted by Maarten Winkels in the late evening: December 8th, 2008
In my article on InfoQ I've looked into how Grails and Flex can be combined to create a rapid application development platform. I think this is one of the most promising combinations for RIA development at the moment. The Flex space is very happening and there are many initiatives going on. A few days ago I encountered this one on the web: http://www.spicefactory.org/. Apart from the funny name, I think it is a very interesting initiative, because it brings some new concepts to the Flex remoting mix.
Article: “Writing JEE applications with Grails and Flex” on InfoQ
Posted by Maarten Winkels at around evening time: November 3rd, 2008
Today InfoQ has posted my article Writing JEE applications with Grails and Flex.
The article describes how the combination of Flex and Grails leads to a highly productive platform for writing JEE applications. It discusses the problems one faces when integrating Flex as client technology and Grails as server technology and details solutions for each of these problems.
The article can be used as a tutorial for writing simple client-server applications with Grails and Flex.
Grails Remoting with Hessian, Burlap and HttpInvoker
Posted by Erik Pragt at around evening time: September 25th, 2008
A short while ago, a collegue and I decided to write an application with Grails and Eclipse RCP. We choose Grails for the ease of development, and Eclipse RCP (in favor of Flex and Plain Old HTML) because we wanted to give our users a solid and native look and feel, for which Eclipse RCP works really well.
Since the Eclipse RCP front-end would actually be a remote front-end, we needed some kind of kind of communication between the client and the server. One of our first idea's was to use XML-RPC, which is pretty well supported in Grails, but it would force us to to do some mapping between our domain and the XML. Since we wanted to use the same domain classes is Eclipse as in Grails (by exporting the Grails domain to external domain jars), we opted for a different approach: Burlap/Hessian.
Querying associations in Grails with HQL, Criteria and HibernateCriteriaBuilder
Posted by Erik Pragt mid-morning: June 4th, 2008
A thing I was playing with today was many-to-many relationships in Grails to create a Tag Cloud. To create a Tag Cloud, I must have a set of key/value pairs, each with a label and a value of the label, which could look like this:
['Java': 5, 'Grails': 16, 'Groovy': 12]
But to query this, I need to query a many to many relationship and produce the above result. This blog will describe how to do this with HQL, Criteria and the HibernateCriteriaBuilder.

Grails Syntax Highlighter Plugin Released
Posted by Erik Pragt at around evening time: May 20th, 2008
Grails syntax highlighter plugin
Yesterday, I released my first plugin for Grails. The goal of the plugin is to do Syntax Highlighting for Code Snippets in HTML pages, for which no plugin existed yet. The plugin supports a whole range of languages, and even includes Groovy Highlighting support. The Grails Synax Highlighter builds on the great work of Alex Gorbatchev, who wrote and maintains the Javascript Syntax Highlighter.

Helpful error messages in Grails
Posted by Erik Pragt around lunchtime: May 4th, 2008
Currenttly, I'm in the process of building a Grails application. While I've built several prototypes/quick hacks, this is actually the first 'real' application I'm building. "So", I thought, "if this is a real application, I'm in need of some real tests!". When you're in the normal flow of developing a Grails application, everything goes so fast, you almost forget about writing the tests. So I decided to do it a bit differently, and do it just like in Java: do it TDD!

Tutorial: Master-Detail screen in Flex, backed up by Grails application
Posted by Maarten Winkels in the early afternoon: February 20th, 2008
In this blog I will show how to create a simple Master-Detail screen in Flex, how to back it up by an application is Grails and how to publish changes via JMS to all Flash clients. Important topics will be binding and remote java-object invocation in Flex and configuring JMS.
A Master-Detail view is a view with a master list, showing a collection of items and a detailed view, most often consisting of a form, in which the a single item can be edited. Clicking an item in the master list will display the details in the detail view.
The combination of a framework for building RIA's (Flex) and a Java based dynamic framework for building services (Grails) seems very promising. I think the high productivity that can easily be achieved by this combination will make it a very attractive choice for your next big project.
