Have a look at databinder or warp-persist for a better implementation.
Should you go with your own implementation, do not forget to clear the
ThreadLocal at the end of the request to prevent:
a) leaking
b) re-using an EntityManager from a previous request (most if not all
application servers use a thread pool)

Hi guys, is this an option to store the JPA entity manager for a
wicket webapp:
public class DBUtil {
private static EntityManagerFactory entityManagerFactory =
Persistence
.createEntityManagerFactory("db");
private static ThreadLocal<EntityManager> emHolder = new
ThreadLocal<EntityManager>() {
protected EntityManager initialValue() {
return entityManagerFactory.createEntityManager();
};
};
public static User getUser(String userName) {
return emHolder.get().find(User.class, userName);
}

If not, thanks for possible better solutions, Juraj
