I successfully got the seam registration example running. I took that example, changed a
few classes so I could begin getting familiar with seam, but I can not get past this one
exception:

I mirrored the registration example almost exactly, here are the relevant files:

| public class Car implements Serializable

|
| private String vin;
| private String make;
| private String model;
| private Integer year;
|
| public Car(String vin, String make, String model, Integer year) {
| this.vin = vin;
| this.make = make;
| this.model = model;
| this.year = year;
| }
|
| public Car() {}
|
| @Id @NotNull
| public String getVin() {
| return vin;
| }
|
| public void setVin(String vin) {
| this.vin = vin;
| }
|
| public void setName(String vin) {
| this.vin = vin;
| }
|
| @NotNull
| public String getMake() {
| return make;
| }
|
| public void setMake(String make) {
| this.make = make;
| }
|
| @NotNull
| public String getModel() {
| return model;
| }
|
| public void setModel(String model) {
| this.model = model;
| }
|
| @NotNull
| public Integer getYear() {
| return year;
| }
|
| public void setYear(Integer year) {
| this.year = year;
| }
|
|
| public String toString()

| em.persist(car);
| log.info("Sold car with vin #{car.vin}");
| return "/sold.jsp";
| }
| else {
| FacesMessages.instance().add("Car vin: #{car.vin} has already been
sold");
| return null;
| }
| }

Hibernate claims to be generating all of the schema, and there are no additional errors to
report. Any help would be greatly appreciated.
Thanks.
