Where is the servletContext available in Grails?

Where is the servletContext available in a Grails application? I tried to acces it in the Config.groovy but it didn't work. Access it in a view is also not possible.

I want to set the temp directory as the directory to store uploaded files in my development and test environment with storage = (File)servletContext["javax.servlet.context.tempdir"].

Following Burt's advice I tried the following in conf/Config.groovy:

environments {
    production {
        grails.serverURL = "http://demo.com"
    }
    development {
        grails.serverURL = "http://localhost:8080/${appName}"
        storageDir = org.codehaus.groovy.grails.web.context.ServletContextHolder
            .getServletContext()["javax.servlet.context.tempdir"]
    }
    test {
        grails.serverURL = "http://localhost:8080/${appName}"
    }

}

... but get this error:

ir' on null object

You can use org.codehaus.groovy.grails.web.context.ServletContextHolder.getServletContext() if you're in code that doesn't already have access to it.

You can access it from any controler. You may be able to access it from bootstrap.groovy but I doubt it. For an example of accessing it from a controler see http://www.grails.org/doc/latest/ref/Controllers/servletContext.html
