Question

i have a grails application and i’m following the tutorial here:
http://www.grails.org/Services

i have some code like

import org.springframework.beans.factory.InitializingBean

class SubmitRequestService implements InitializingBean{
    def GrailsApplication1
    def setting

    void afterPropertiesSet(){
        this.setting = GrailsApplication1.config.setting
    }

    def void sendHistoricalContract(HistoricalContract hc_instance){
        //... blah blah whatever code      
    }
}

class SubmitRequestController {    
    def submitRequestService
    static allowedMethods = [save: "POST", update: "POST", delete: "POST"]

    def index = {
        // .... blah blah whatever code
        submitRequestService.sendHistoricalContract(historicalContractInstance)
    }    
}

No whatever i do, i can’t seem to get the service to be injected into the controller. Whenever I get to the line where i call the service i get the error:

ERROR errors.GrailsExceptionResolver – Cannot invoke method sendHistoricalContract() on null object

What am i doing wrong?

Thanks in advance

Burt’s answer is helpful (+1 to Burt) but in case others are following the tutorial here:
http://www.grails.org/Services
and experiencing the same issue i had, i want to make it explicit:

Services go in their own files under
the Services directory, you do not
combine them with controllers, even
though it looks that way in the code
examples

See Burt’s comment above on additional resources to Services and the Spring Framework.
