Description ievans 2006-03-23 18:05:47 UTC
When you rename Java Persistence entity names or entity fields/properties in
NetBeans 5.5, the refactoring engine doesn't rename annotation metadata
elements, resulting in deployment and runtime errors.

For example, if I have a BankCustomer entity class with a persistent field
@Table(name = "BANK_CUSTOMER")
@NamedQueries( {
            name = "BankCustomer.FindByCustomerId", 
            query = "SELECT a FROM BankCustomer a WHERE a.customerId =
public class BankCustomer {
    @GeneratedValue(strategy=GenerationType.TABLE, generator="customerIdGen")
    @Column(name = "CUSTOMER_ID", nullable = false)
    private String custoemrId;

And I want to rename the entity class to Customer, and customerId to id, the
refactoring engine doesn't refactor the metadata:
@Table(name = "BANK_CUSTOMER")
@NamedQueries( {
            name = "BankCustomer.FindByCustomerId", 
            query = "SELECT a FROM BankCustomer a WHERE a.customerId =
public class Customer {
    @GeneratedValue(strategy=GenerationType.TABLE, generator="customerIdGen")
    @Column(name = "CUSTOMER_ID", nullable = false)
    private String id;

There are three errors here:
1. The NamedQuery name doesn't match the entity class name and the renamed field.
2. The query is incorrect as it's schemaname is still BankCustomer, but should
have been renamed to Customer.
3. The fields and named parameters in the query are also incorrect ("customerId"
rather than "id").

The mappedBy element in relationship annotations are also not updated during
refactoring, which results in deployment errors.

The refactoring engine should update annotation metadata.

In my opinion this can be seen rather as a bug in J2EE refactoring. Besides,
reassigning to appropriate component.
Comment 2 Jiri Kovalsky 2006-03-23 18:24:56 UTC
Changing subcomponent as well.

Comment 4 Petr Blaha 2006-03-24 08:53:37 UTC
I'm changing priority to P2 since this feature is very important for persitence
Comment 5 Erno Mononen 2006-04-14 07:58:18 UTC
Partially fixed, mappedBy references should be now updated.

Comment 7 Erno Mononen 2006-05-31 09:59:55 UTC
Changing this to enhancement as agreed with Petr Blaha. Issue with mappedBy 
references is now resolved, and support for ejb-ql refactoring is something that 
has not been present in previous releases.

Closed duplicate issue was from netcat - adding prefix here.

Comment 11 Rochelle Raccah 2006-06-20 21:10:11 UTC
2 duplicates filed in the past day - perhaps this should be a defect, not an

Also, be sure to see Jesse's comments on Issue 78634.
Comment 12 Petr Jiricka 2006-06-21 08:39:15 UTC
Since the original problem reported here is partially fixed, would it be useful
to file a new issue with just the remaining part?

Regarding a possible solution, would it be possible to display a warning to the
user prompting her to manually update the NamedQueries?
Comment 13 Sergey Petrov 2012-02-09 19:15:25 UTC
nq refactoring isn't supported yet, but nqs are verified now and warning is shown if necessary, may work in this case (from 7.2)
Comment 14 Sergey Petrov 2012-05-12 07:51:30 UTC
mappedBy is implemented in 205539
as named queries parsing/completion etc is added in 7.2 it may be possible to add named queries refactoring later also.
