私は ejb + JPA (Hibernate) アプリケーションに取り組んでいます。データベースにデータを挿入すると、挿入されません。しかし、sessionbean からエラーはスローされません。
以下はコードです。
@PersistenceContext private EntityManager em;
@Override
public void insterCustomerDetails(Customer customer) {
// TODO Auto-generated method stub
try{
System.out.println("properties:::"+em.getProperties());
System.out.println("Model :::"+em.getMetamodel());
System.out.println("Name ::::" + customer.getName() + "::customer id ::"+customer.getCustomer_id()+"::email::"+customer.getEmail_id()+"::address::"+customer.getAddress()+
":::ph number::"+customer.getPhNumber());
em.persist(customer);
}catch(Exception e){
e.printStackTrace();
}
}
