[Hibernate-JIRA] Created: (HHH-2355) CGLIBLazyInitializer can not access a public member if parent class is not public
by Daniel Beland (JIRA)
CGLIBLazyInitializer can not access a public member if parent class is not public
---------------------------------------------------------------------------------
Key: HHH-2355
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2355
Project: Hibernate3
Type: Bug
Versions: 3.2.1
Reporter: Daniel Beland
In hibernate 3.2.1, CGLIBLazyInitializer cannot acces a public method if it has been inherited from a parent class that is not public.
Let's say we have a class A, modifier = default (package) with a public method getName() (and setName(String name)).
Then I create a public class B that extends A.
in my code I can retrieve B from the database:
B b = session.load(B.class, new Integer(1), LockMode.NONE);
I receive b with all the values set correctly (So at this point, Hibernate was able to use the method setName() correctly).
In my code if I then try to use b.getName(), I receive and error:
java.lang.IllegalAccessException-->Class org.hibernate.proxy.pojo.cglib.CGLIBLazyInitializer can not access a member of class A with modifiers "public"
But I am not trying to access A.getName(), but B.getName() (which is a public method in a public class).
This was working perfectly with Hibernate 2.1.7c and 3.1.3.
The full information about my problem can be found here: http://forum.hibernate.org/viewtopic.php?t=969453

Reporter: Fred
I can't get the N first records from a select request using the setMaxResults method.
HB generates a request that can not be understood by DB2 (select * from ( select rownumber() over() as rownumber etc.... see first stacktrace below)
Moreover, using setFetchSize does not work (see second stack trace below the first one).
Is there a way to tell HB to append " fetch first 10 rows only" to the query (as a workaround) ? Because my DB2 can understand that one :
select *
from MYTABLE
where numseq = '2'
fetch first 10 rows only
thanks !

[Hibernate-JIRA] Created: (ANN-598) Add ON clause to @ForeignKey
by Christian Bauer (JIRA)
Add ON clause to @ForeignKey
----------------------------
Key: ANN-598
URL: http://opensource.atlassian.com/projects/hibernate/browse/ANN-598
Project: Hibernate Annotations
Issue Type: New Feature
Components: binder
Reporter: Christian Bauer
More important than it sounds:
@org.hibernate.annotations.ForeignKey(name = "FK_FEED_DIRECTORY_ID")
I need ON CASCADE DELETE on many of my foreign keys, so I have to do this right now via:
<hibernate-mapping>
<database-object>
<create>
alter table FEED drop constraint FK_FEED_DIRECTORY_ID;
alter table FEED add constraint FK_FEED_DIRECTORY_ID foreign key (DIRECTORY_ID) references NODE on delete cascade;
</create>
<drop></drop>
</database-object>
</hibernate-mapping>
This is a bit annoying, especially since @JoinColumn(columnDefinition) is also not an option - I don't want to hardcode my HSQL datatypes.
So we should accept a parameter on @ForeignKey (I know that the Hibernate binder doesn't have that notion at all, we need it in native Hibernate as well) that accepts "[ON {DELETE | UPDATE} {CASCADE | SET DEFAULT | SET NULL}];" and does the right thing during schema export.

[Hibernate-JIRA] Created: (ANN-554) NPE with @Id on @OneToOne

NPE with @Id on @OneToOne
-------------------------
Key: ANN-554
URL: http://opensource.atlassian.com/projects/hibernate/browse/ANN-554
Project: Hibernate Annotations
Type: Bug
Versions: 3.2.1
Environment: Hibernate 3.2.2 GA, Hibernate Annotations 3.2.1, J2SE 1.6.0-b105 on Debian GNU/Linux sid, PostgreSQL 7.4
Reporter: Loïc Minier
Priority: Minor
Hi,
(Note: I originally reported this on the forum, but the lack of response suggests this might be a bug in Hibernate Annotations or Hibernate; the forum topic is at: http://forum.hibernate.org/viewtopic.php?t=970823)
I hope it's not a misuse of Hibernate, but I'm trying to use @Id on @OneToOne, and this causes the following NPE when running hbm2ddl:
java.lang.NullPointerException

at org.apache.tools.ant.launch.Launcher.run(Launcher.java:246)
at org.apache.tools.ant.launch.Launcher.main(Launcher.java:67)
What I'm trying to do at the application level is:
Foo class and table
long foo_id, primary key
FooData fooData, nulllable=true
FooData class and table
foo_id references Foo(foo_id), nullable=false
This is expressed in Java as:
@Entity
@Table(name = "foo")
public class Foo {
@Id @GeneratedValue
@Column(name = "foo_id")
Long id;
@OneToOne(mappedBy = "foo", cascade = CascadeType.ALL)
FooData fooData;
...
@Entity
@Table(name = "foo_data")
public class FooData {
@Id
@OneToOne
@JoinColumn(name = "foo_id", nullable = false)
Foo foo;
This causes a NPE here.
If I use a real Id on FooData, e.g.:
@Id
@Column(name = "foo_data_id")
Long id;
it works, and I end up with:
- foo_id in table foo as a primary key
- foo_data_id in table foo_data as a primary key
- foo_id in table foo_data not null
- foo_id in table foo_data references foo_id in table foo
I don't want a foo_data_id, I don't need it, hence the lack of it which leads to the NPE.
Bye,

[Hibernate-JIRA] Created: (HBX-779) jdbc reengineer sql-type problem with oracle 9i

jdbc reengineer sql-type problem with oracle 9i
-----------------------------------------------
Key: HBX-779
URL: http://opensource.atlassian.com/projects/hibernate/browse/HBX-779
Project: Hibernate Tools
Type: Bug
Components: reverse-engineer
Versions: 3.2beta8
Environment: windowsxp sp2, jdk 1.4.2, eclipse 3.1.2
Reporter: jacky hua
I used the ant task hibernate-tools provided like the below to generate hbms xml
<target name="default" description="generate hbm">
<delete dir="./generate"/>
<mkdir dir="./generate"/>
<hibernatetool destdir="./generate">
<jdbcconfiguration
configurationfile="./metadata/hibernate.cfg.xml"
revengfile="./metadata/hibernate.reveng.xml"
packagename="net.ema.examples.sa"
detectmanytomany="true"
detectoptimisticlock="true">
</jdbcconfiguration>
<hbm2hbmxml destdir="./generate" />
</hibernatetool>
</target>
the ./metadata/hibernate.cfg.xml like the below:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-reverse-engineering
SYSTEM "http://hibernate.sourceforge.net/hibernate-reverse-engineering-3.0.dtd" >
<hibernate-reverse-engineering>
<schema-selection match-catalog="TITAN" match-schema="TITAN" />
<type-mapping>
<!-- jdbc-type is name fom java.sql.Types -->
<!-- length, scale and precision can be used to specify the mapping precisly -->
<sql-type jdbc-type="NUMERIC" precision="1"
hibernate-type="boolean" />
<!-- the type-mappings are ordered. This mapping will be consulted last,
thus overriden by the previous one if precision=1 for the column -->
<sql-type jdbc-type="NUMERIC" precision="19" hibernate-type="long" />

</type-mapping>
<!-- BIN$ is recycle bin tables in Oracle -->
<table-filter match-name="BIN$.*" exclude="true" />
</hibernate-reverse-engineering>
But the <sql-type jdbc-type="NUMERIC" precision="19" hibernate-type="long" /> didn't work, also generate big_decimal type not long type, otherwise the others two sql-type rules worked. the not affected column:USER_ID was pk of my table. the generated hbm file is like the below:
<class name="net.ema.examples.sa.UserModel" table="T_SA_USER" schema="TITAN">
<id name="userId" type="big_decimal">
<column name="USER_ID" scale="0" />
<generator class="assigned" />
</id>

</property>
<property name="isOrgAdmin" type="java.lang.Boolean">
<column name="IS_ORG_ADMIN" precision="1" scale="0" />
</property>
<property name="remark" type="string">
