Grails: how to properly use/install the rest plugin - rest

Question

I create a new grails app and do grails install-plugin rest. App builds. Now I add exactly the example from the plugin page: http://grails.org/plugin/rest into the bootstrap and have:
import l2http.*
class BootStrap {
def init = { servletContext ->
withHttp(uri: "http://www.google.com") {
def html = get(path : '/search', query : [q:'Groovy'])
assert html.HEAD.size() == 1
assert html.BODY.size() == 1
}
}
def destroy = {
}
}
This crashes with the following error:
| Loading Grails 2.0.0
| Configuring classpath.
| Environment set to development.....
| Packaging Grails application.....
| Compiling 1 source files.....
| Running Grails application

Answer 1

The withHttp or any method added by the rest-plugin is injected to the Controllers and Services not to the BootStrap class. Please try it within Services or Controllers.
Cheers.
