Ehcache and Grails

Grails 1.2RC1 and higher use Ehcache as the default Hibernate second level cache. However earlier versions of Grails ship with the Ehcache library and are very simple to enable.

The following steps show how to configure Grails to use Ehcache. For 1.2RC1 and higher some of these steps are already done for you.

Grails in the enterprise: Using Grails with JMX, Spring, and log4j

In this installment of Mastering Grails, series author Scott Davis puts to rest any qualms about Grails' readiness for the enterprise. You'll see how to use Grails with enterprise-caliber libraries including the Java(tm) Management Extensions (JMX), Spring, and log4j.

Grails + Spatial Data using PostgreSQL, PostGIS

PostGIS
PostGIS adds support for geographic objects to the PostgreSQL object-relational database. In effect, PostGIS "spatially enables" the PostgreSQL server, allowing it to be used as a backend spatial database for geographic information systems (GIS), much like ESRI's SDE or Oracle's Spatial extension. PostGIS follows the OpenGIS "Simple Features Specification for SQL" and has been certified as compliant with the "Types and Functions" profile.

Hibernate Spatial
Hibernate Spatial is a generic extension to Hibernate for handling geographic data. Hibernate Spatial is open source and licensed, like Hibernate, under the LGPL license.
 
Hibernate Spatial allows you to deal with geographic data in a standardized way. It abstracts away from the specific way your database supports geographic data, and provides a standardized, cross-database interface to geographic data storage and query functions.
 
Hibernate Spatial supports most of the functions of the OGC Simple Feature Specification. Supported databases are: Oracle 10g/11g, Postgresql/Postgis, and MySQL.

 JTS Topology Suite
 
The JTS Topology Suite is an API of 2D spatial predicates and functions. It has the following design goals:
 
  * JTS conforms to the Simple Features Specification for SQL published by the Open GIS Consortium
  * JTS provides a complete, consistent, robust implementation of fundamental 2D spatial algorithms
  * JTS is fast enough for production use
  * JTS is written in 100% pure JavaTM
  * JTS is open source (under the LGPL license)

Nimble: prepared Grails application base

Nimble is an "Application Base for Grails", a base set of components that all web applications require to function.

Nimble provides

• Flexible authentication sources including locally hosted accounts, Facebook and OpenID. In the near future we plan to have support for LDAP, SAML 2.x and more
• Fine grained access control from the web tier through to backend service logic. Permissions can be applied to users, roles and groups. Users can be members of an unlimited number of groups. Both users and groups are able to be assigned roles. Enabling permissions to cascade through this structure is where Nimble gains its real access control flexibility. All of this is dynamic and modifiable at run time.
• User profiles and social features such as status updates. We've only scratched the surface of what is possible here and hope to really expand this in the future.
• A gorgeous set of interactive UI's to manage all of the above.

Grails and Continuous Integration: An Essential Combo

Grails is a fantastic framework. As well as being ultra-productive and fun to work with, it encourages good testing practices, and provides a swathe of tools to make writing unit, integration, and web tests a real pleasure. As we will see, Grails also lends itself quite well to build automation. However, Grails is not Maven. Grails has a fairly loose concept of the software development lifecycle, and is happy to let you bundle up and deploy your application as a WAR file without running all the unit and integration tests first. A Continuous Integration (CI) server can help you keep the flexibility of the Grails development process, and still ensure that your code is fully tested for each and every code change. In this article, we will take a look at how you can introduce Continuous Integration into your Grails project. More specifically, we will walk through how you can automate your Grails testing and code quality metrics with Hudson, a popular open source CI tool.
