[JBoss Seam] - IllegalArgumentException: Could not set field value by refle - jboss-user

Tuesday, 28 November 2006

Trying to get a simple example to run with an entity bean, test.Test2, being injected into
a session bean, test.TestSessionBean upon form submit. I know this must be something
simple but can't seem to figure it out.. Using 1.1.0 CR1. Code/stack trace as follows.
Thanks!

@Stateless
  | @Name("testSessionBean")
  | public class TestSessionBean implements TestSession {
  | 
  |   @In
  |   private Test2 test2;

@Entity
  | @Name("test2")
  | @Scope(SESSION)
  | @Table(name="test2")
  | public class Test2 implements Serializable{
  | 
  |   @Id @GeneratedValue(strategy=GenerationType.AUTO)
  |   private long id;
  |   private String key;
  |   private String value;
