Hola,

indent]@WebService
public class Greeting {
 
@PrimaryKey
@Persistent (valueStrategy = IdGeneratorStrategy.IDENTITY)
private Key key;
 
@Persistent
private User author;
.....
@WebMethod
public Key getKey() {
    return key;
}
@WebMethod
public User getAuthor(){
    return author; [/indent]


Y esta es la ejecución del comando wsgen en el cmd y el error que me sale:
