Grails Integration Strategies

It's amazing how quickly one can build web applications with Grails in a greenfield environment, but most of us do not have that luxury. We have existing infrastructure and applications that we have to maintain and extend. We have legacy databases (or legacy database administrators) to deal with. Does this mean we cannot benefit from the magic of Grails? No way! The ease of use and productivity of Grails is matched by its power and flexibility. In this session we will discuss some of the ways that Grails can be integrated with the enterprise; EJB/JSF applications, Spring/Hibernate, legacy databases, and even non-Java applications.

Some of the strategies we will cover include:

  • Integrating with existing Spring MVC applications
  • JSF Integration with IceFaces
  • Communicating enterprise-wide with Web Services
  • Calling EJB session beans from a Grail application
  • Using Grails' ORM mapping to access legacy databases
  • Accessing JNDI resources from Grails
  • Using AJAX to call Grails' services from any web page
