One of the best features of the Grails platform is that its modular architecture makes developing plugins very easy. As a result, hundreds of plugins have already been developed and made available in the standard repository, with the number growing almos

Groovy and the Spring framework are old friends. Spring includes dynamic beans that can be modified while a system is still running, and of course the Grails framework is built on top of Spring MVC. Here we'll illustrate all the ways that Groovy works w
