Hello, I'm very new to app-engine but I'm used to JPA and I can't find a way to use Open EntityManager in View with app-engine and JPA.
My code is structured like this: DomainDAO -> This is where I access the datastore through JPA DomainService -> Some business logic before saving DomainController -> To show the domain on the page This is a sample method of one of my DAOs: public Guardian findByGoogleUserId(String userId) { if (userId) { def result = jpaTemplate.findByNamedParams("select g from Guardian g where g.googleUserId = :userId", [userId: userId]) if (result) { return result[0] } } return null } I'm using Spring therefore I tried to configure the OpenEntityManagerInViewInterceptor, if this works as it's supposed to I shouldn't get JDODetachedFieldAccessException anymore, but I still get it. Is it possible to implement this pattern with app-engine and JPA? -- You received this message because you are subscribed to the Google Groups "Google App Engine for Java" group.
