mappings closure does not exists for class UrlMappings

I've just started working on a new grails application, and early in the piece I hit this error: 2008-03-05 18:39:20.715::WARN: Failed startup of context org.mortbay.jetty.webapp.WebAppContext@1fcb845{/jtchat,/home/prule/workspace/jtchat/web-app} org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.codehaus.groovy.grails.plugins.web.taglib.ApplicationTagLib': Initialization of bean failed; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'grailsUrlMappingsHolder': Cannot resolve reference to bean 'urlMappingsTargetSource' while setting bean property 'targetSource'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'urlMappingsTargetSource': Cannot resolve reference to bean 'grailsUrlMappingsHolderBean' while setting constructor argument; nested exception is org.springframework.beans....

Integration testing Griffon services

I wanted to create an integration test for some Griffon services - where I wanted to set up some data first, then check that the service produced the appropriate results. Therefore, I wanted the database working normally, but I needed access to a configured Griffon application and the required services. My issue was how to get hold of the services? They don't automatically get injected as I first expected. But luckily, StackOverflow and Andres to the rescue:
