Injecting sessionFactory into grails service when calling from a groovy script

I have a grails service: ``` MyService { def sessionFactory void someMethod() { //... sessionFactory.currentSession.createSQLQuery(sql); //... } } ``` I want to invoke this service from a groovy script (located in src/groovy). Im invoking via the grails command - grails test run-script src\groovy\CallMyService.groovy. The sessionFactory is null when called this way (it works fine when run as an integration test). But I would like to invoke it via a script. How can I inject the sessionFactory into the service? I tried modifying the RunScript.groovy, for eg like this: ``` def sessionFactory = appCtx.getBean("sessionFactory") def session = SessionFactoryUtils.getSession(sessionFactory, true) TransactionSynchronizationManager.bindResource(sessionFactory, new SessionHolder(session)) ``` but that didnt help. Any help appreciated.
