Right.. That did it. Thanks.
Next bug.
Just to set the stage, an Athlete can have several workouts. I am able to
create an athlete and it's stored in the DB. After which, I attempt to create a
Workout. A workout however is created when a user uploads a CSV file of their
workout.
I am able to parse this, load it into the Workout Entity bean. However, I
want to be able to associate this with the athlete that was previously select..
Here is the code:
| @Stateless
| @Scope(SESSION)
| @Name("uploadWorkout")
| public class UploadWorkoutBean implements UploadWorkout
| {
|
| @Logger
| private Log log;
|
| @In Athlete athlete;
|
| @In(value = "uploadedWorkout", create = true)
| private UploadedWorkout uploadedWorkout;
|
| @In
| FacesMessages facesMessages;
|
| @PersistenceContext
| private EntityManager em;
|
| public void uploadWorkout()
| {
| // implement your business logic here
| log.info("uploadWorkout.uploadWorkout() action called");
| log.info("Content Type is: " +
uploadedWorkout.getContentType());
| log.info("FileName is: " + uploadedWorkout.getFileName());
|
| WorkoutReader workoutReader = new WorkoutReader();
|
| ArrayList<Workout> workouts =
workoutReader.readFile(uploadedWorkout.getUploadedFile());
| Workout workout = null;
| // Stuff it into the DB
|
| for(int i=0; i< 1 ;i++)
| {
| workout = workouts.get(i);
| log.info(athlete.getLastName());
| em.persist(workout);
| }
|
| facesMessages.add("uploadWorkout");
| }
|
The error that is thrown is:
