The following comment has been added to this issue:
Author: Dominik Roblek
Created: Mon, 20 Oct 2003 3:56 AM
Body:
Thanks for help. The problem really appeared because of CGLIB tried to instantiate an instance of the instrumented class and this instantiation was not possible at the Hibernate configuration time because of poor design of my class. I fixed it and now it works fine.

Here is an overview of the issue:
---------------------------------------------------------------------
Key: HB-401
Summary: reflection optimizer bug
Type: Bug
Status: Closed
Priority: Major
Resolution: WON'T FIX
Project: Hibernate2
Components:
core
Versions:
2.1 beta 4
Assignee: Gavin King
Reporter: Dominik Roblek
Created: Wed, 15 Oct 2003 5:32 AM
Updated: Sat, 18 Oct 2003 6:29 AM
Description:
I have some persistent classes, which cannot be instrumented with CGLIB reflection optimizer. In Hibernate versions prior to 2.1beta4 I've got the following correct log messages and everything worked fine:
---
14:26:48,230 INFO [:] SessionFactoryImpl:109 - building session factory
14:26:57,507 INFO [:] ReflectHelper:328 - reflection optimizer disabled for: si.marand.maf.server.jastreb.party.module.entity.PersonEntity, NullPointerException: null
14:26:59,175 INFO [:] ReflectHelper:328 - reflection optimizer disabled for: si.marand.maf.server.jastreb.party.module.entity.BankEntity, NullPointerException: null
14:27:06,349 INFO [:] SessionFactoryObjectFactory:86 - Factory name: maf-server-hibernate-sessionFactory
---
But in version 2.1beta4 is instead of this in the same phase of startup process thrown an exception, which stops application. The excerption from log it here:
---
12:18:51,464 ERROR [:] LazyInitializer:62 - CGLIB Enhancement failed

...
---
Besides of this bug it seems, that hibernate.cglib.use_reflection_optimizer setting is ignored in beta4 and "true" is allways used as it's value.

Body:
Ok that was a middlegen issue.
Previously the generated xml was -
<id
generator-class="assigned"
name="channelId"
type="int"
column="channel_id"
not-null="true"
length="3"
>
Changed the template in hibernate plugin for middlegen to generate it with " />"
Now next error - The ant task and the xml file are otherwise same.

I have the following problems: I try to do a SchemaUpdate over a MySQL DB over database where the update should add some fields to some table, but the SchemaUpdate try to re-create the table, with <<SQLException>> results... I did a debug to see what happens and the problem is at net.sf.hibernate.tool.hbm2ddl.DatabaseMetadata at line 47 , where the tool finds if the table exists or not, to create or update the table, : public TableMetadata getTableMetadata(String name) throws HibernateException { ... String[] types = {"TABLE"}; ResultSet rs = null; try { try { THIS>>rs = meta.getTables(null, "%", name.toUpperCase(), types); while ( rs.next() ) { if ( name.equalsIgnoreCase( rs.getString("TABLE_NAME") ) ) { table = new TableMetadata(rs, meta); tables.put( name.toUpperCase(), table ); break; } The line 47 is rs=meta.getTables(null, "%", name.toUpperCase(),Types); The problem is that hibernate creates the tables (with SchemaExport) with lower case, and MySQL is case sensitive for table names on Unix (see http://www.mysql.com/doc/en/Name_case_sensitivity.html). But the .getTables call finds the upper case table name. Then, never is found, and it try to create the table when it exists. The fix is remove the .toUpperCase() : rs = meta.getTables(null, "%", name, types); or SchemaExport should create the tables with upper case. Hibernate is great. Thanks for all. --------------------------------------------------------------------- JIRA INFORMATION: This message is automatically generated by JIRA.

Description:
I have a relatively complex hierarchy of objects:
A is common superclass
B, C, D are subclasses
D incapsulates collections of B and C
here is my hbm.xml file:
<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC
"-//Hibernate/Hibernate Mapping DTD//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-2.0.dtd">
<hibernate-mapping>
<class name="A">
<id name="id">

<param name="column">next_value</param>
<param name="max_lo">100</param>
</generator>
</id>
<discriminator column="class_name"/>
<property name="f1"/>
<subclass name="B">
<property name="f2"/>
</subclass>
<subclass name="C">
<property name="f3"/>
</subclass>
<subclass name="D">
<set name="lnkB" cascade="all">
<key column="d_id"/>
<one-to-many class="B"/>
</set>
<set name="lnkC" cascade="all">
<key column="d_id"/>
<one-to-many class="C"/>
</set>
<property name="f4"/>
</subclass>
</class>
</hibernate-mapping>
here are the classes:
public abstract class A {
private Long id;
private String f1;
public Long getId() { return id; }
public void setId(Long id) { this.id = id; }
public String getF1() { return f1; }
public void setF1(String f1) { this.f1 = f1; }
}
public class B extends A {
private String f2;
public String getF2() { return f2; }
public void setF2(String f2) { this.f2 = f2; }
}
public class C extends A {
private String f3;
public String getF3() { return f3; }
public void setF3(String f3) { this.f3 = f3; }
}
public class D extends A {
private String f4;
private Collection lnkB;
private Collection lnkC;
public String getF4() { return f4; }
public void setF4(String f4) { this.f4 = f4; }
public Collection getLnkB() { return lnkB; }
public void setLnkB(String lnkB) { this.lnkB = lnkB; }
public String getLnkC() { return lnkC; }
public void setLnkC(String lnkC) { this.lnkC = lnkC; }
}
I persisted data to the database using the following code:
public class TestMain {
static Session session;
static SessionFactory sessionFactory;
public static Collection createB() throws HibernateException, SQLException {
Collection results = new HashSet();
B b = new B();
b.setF2("foo");
results.add(b);
b = new B();
b.setF2("bar");
results.add(b);
return results;
}
public static Collection createC() throws HibernateException, SQLException {
Collection results = new HashSet();
C c = new C();
c.setF3("foo");
results.add(c);
c = new C();
c.setF3("bar");
results.add(c);
return results;
}
public static D createD(Collection b, Collection c) throws HibernateException, SQLException {
D d = new D();
d.setF1("foo");
d.setLnkB(b);
d.setLnkC(c);
session.save (d);
System.out.println ("Persisting D");
return d;
}
public static void main(String[] args) {
D d;
try {
sessionFactory = new Configuration().configure().buildSessionFactory();
if (sessionFactory == null) { System.out.println ("null session factory returned"); return; }
System.out.println ("Got Session Factory");
session = sessionFactory.openSession();
Collection b = createB();
Collection c = createC();
d = createD(b, c);
session.flush();
session.connection().commit();
System.out.println ("Committing");
session.close();
} catch (MappingException e){
System.out.println (e);
} catch (HibernateException e) {
System.out.println(e);
}
catch (Throwable e) {
System.out.println (e);
e.printStackTrace();
}
}
}
then I started my application again but instead of persistence I did retrieval (I looked up id of D instance in the database):
D d = (D) session.load(D.class, new Long(1615));
But it failed with the message:
Object with id: 1618 was not of the specified subclass: C (loaded object was of wrong class)
Indeed, the object with id 1618 had "B" in the discriminator field and database record corresponded to B instance.

Summary: SchemaExport unable to find getter for tO or cC properties.
Type: Bug
Status: Closed
Priority: Minor
Resolution: REJECTED
Project: Hibernate2
Components:
toolset
Versions:
2.0.3
Assignee:
Reporter: Brian Duguid
Created: Thu, 16 Oct 2003 9:03 AM
Updated: Sat, 18 Oct 2003 6:22 AM
Environment: Coding and using tool in JBuilder 9 Enterprise
Description:
The SchemaExport tool works fantastic with the exception of compiling for properties that have the second letter in uppercase even though the first leter is lowercase.
For example, I have an object that is used to store e-mail communications. The "to," "cc," and "bcc" addresses properties are written as tO, cC, and bCC so the getter and setters are "pretty" (getTO(), getCC(), getBCC()).
I am able to fix the error by having the first two letters of the property as lowercase and the third letter as uppercase is acceptable. i.e. property bcC with getBcC() works fine.
The error that is thrown read as:
ERROR [main] (Configuration.java:233) - Could not compile the mapping document

Ah yeah, I think CGLIB tries to instantiate an instance of the class when it creates a "proxy factory". Well, you can ask the CGLIB guys about this. But I won't change Hibernate - it is now using CGLIB as recommended by the CGLIB guys.

Description:
I have some persistent classes, which cannot be instrumented with CGLIB reflection optimizer. In Hibernate versions prior to 2.1beta4 I've got the following correct log messages and everything worked fine:

But in version 2.1beta4 is instead of this in the same phase of startup process thrown an exception, which stops application. The excerption from log it here:

Besides of this bug it seems, that hibernate.cglib.use_reflection_optimizer setting is ignored in beta4 and "true" is allways used as it's value.

This is an interesting observation. I'm half inclined to accept your patch. OTOH, it seems to be a problem specifically with the JCS cache architecture. (For example, it would not affect the new HashtableCache.) Note that we are de-emphasizing JCS!
Anyway, I'll give it some thought when I do the distributed cache stuff with Bela, but for now this kind of stuff -can- actually be handled in the pluggable cache layer by passing properties, etc.

Description:
I want to map the same class in two different sessionFactories using two different databases.
As the cache region is defined only by the class name, the cache is not able to differentiate instances of the same class with the same id in different databases.
I have made a patch for Hibernate 2.0.3 which just add a new parameter 'cache-region-prefix' in the session factory configuration and it works perfectly.
As the caching system is completely being refactored, it would be really cool if this simple fix was included in the refactoring.
Thanks.

All, I'm trying to do an inner join within Hibernate, but I'm having some difficulties and am hoping there's some knowledgeable people on the list. I have two objects: a Session object and an Account object, which can be joined in a query with session.field = account.field4; however, I don't have any mappings defined in the Hibernate .hbm.xml files to this effect. Table Structure, session.field1 = account.field4: Session Account ------- ------- id id field1 <-| field3 field2 |-> field4 Even though I don't have the mappings defined between objects in the Hibernate configuration files (for reasons I won't go into), I want to do an inner join and return objects of type Session only if account.field3 equals a particular value. In SQL, I could do this using something like: SELECT * FROM session LEFT JOIN account ON Session.field1 = account.field4 WHERE account.field3 = 'value' However, I can't seem to get Hibernate to perform this kind of functionality. This is what I'm using as a Hibernate Query right now: String query = "FROM session IN CLASS org.express.test.Session " + "WHERE field1 = '" + field1 + "' "; Can someone point me in the right direction?

I have a relatively complex hierarchy of objects:

D incapsulates collections of B and C
here is my hbm.xml file:

</set>
<property name="f4"/>

here are the classes:
public abstract class A {
private Long id;
private String f1;
public Long getId() { return id; }
public void setId(Long id) { this.id = id; }
public String getF1() { return f1; }
public void setF1(String f1) { this.f1 = f1; }
}
public class B extends A {
private String f2;
public String getF2() { return f2; }
public void setF2(String f2) { this.f2 = f2; }
}
public class C extends A {
private String f3;
public String getF3() { return f3; }
public void setF3(String f3) { this.f3 = f3; }
}
public class D extends A {
private String f4;
private Collection lnkB;
private Collection lnkC;
public String getF4() { return f4; }
public void setF4(String f4) { this.f4 = f4; }
public Collection getLnkB() { return lnkB; }
public void setLnkB(String lnkB) { this.lnkB = lnkB; }
public String getLnkC() { return lnkC; }
public void setLnkC(String lnkC) { this.lnkC = lnkC; }
}
I persisted data to the database using the following code:
public class TestMain {
static Session session;
static SessionFactory sessionFactory;
public static Collection createB() throws HibernateException, SQLException {
Collection results = new HashSet();
B b = new B();
b.setF2("foo");
results.add(b);
b = new B();
b.setF2("bar");
results.add(b);
return results;
}
public static Collection createC() throws HibernateException, SQLException {
Collection results = new HashSet();
C c = new C();
c.setF3("foo");
results.add(c);
c = new C();
c.setF3("bar");
results.add(c);
return results;
}
public static D createD(Collection b, Collection c) throws HibernateException, SQLException {
D d = new D();
d.setF1("foo");
d.setLnkB(b);
d.setLnkC(c);
session.save (d);
System.out.println ("Persisting D");
return d;
}
public static void main(String[] args) {
D d;
try {
sessionFactory = new Configuration().configure().buildSessionFactory();
if (sessionFactory == null) { System.out.println ("null session factory returned"); return; }
System.out.println ("Got Session Factory");
session = sessionFactory.openSession();
Collection b = createB();
Collection c = createC();
d = createD(b, c);
session.flush();
session.connection().commit();
System.out.println ("Committing");
session.close();
} catch (MappingException e){
System.out.println (e);
} catch (HibernateException e) {
System.out.println(e);
}
catch (Throwable e) {
System.out.println (e);
e.printStackTrace();
}
}
}
then I started my application again but instead of persistence I did retrieval (I looked up id of D instance in the database):
D d = (D) session.load(D.class, new Long(1615));
But it failed with the message:
Object with id: 1618 was not of the specified subclass: C (loaded object was of wrong class)
Indeed, the object with id 1618 had "B" in the discriminator field and database record corresponded to B instance.

Author: Andrey Volozin

Body:
I did some research and probably (IMHO) the reason is that it doesn't use discriminator value in SQL "where" clause when loading collection. So it loads the data from all the collections instead of one particular.

public String getLnkC() { return lnkC; }
public void setLnkC(String lnkC) { this.lnkC = lnkC; }
}
I persisted data to the database using the following code:
public class TestMain {
static Session session;
static SessionFactory sessionFactory;
public static Collection createB() throws HibernateException, SQLException {
Collection results = new HashSet();
B b = new B();
b.setF2("foo");
results.add(b);
b = new B();
b.setF2("bar");
results.add(b);
return results;
}
public static Collection createC() throws HibernateException, SQLException {
Collection results = new HashSet();
C c = new C();
c.setF3("foo");
results.add(c);
c = new C();
c.setF3("bar");
results.add(c);
return results;
}
public static D createD(Collection b, Collection c) throws HibernateException, SQLException {
D d = new D();
d.setF1("foo");
d.setLnkB(b);
d.setLnkC(c);
session.save (d);
System.out.println ("Persisting D");
return d;
}
public static void main(String[] args) {
D d;
try {
sessionFactory = new Configuration().configure().buildSessionFactory();
if (sessionFactory == null) { System.out.println ("null session factory returned"); return; }
System.out.println ("Got Session Factory");
session = sessionFactory.openSession();
Collection b = createB();
Collection c = createC();
d = createD(b, c);
session.flush();
session.connection().commit();
System.out.println ("Committing");
session.close();
} catch (MappingException e){
System.out.println (e);
} catch (HibernateException e) {
System.out.println(e);
}
catch (Throwable e) {
System.out.println (e);
e.printStackTrace();
}
}
}
then I started my application again but instead of persistence I did retrieval (I looked up id of D instance in the database):
D d = (D) session.load(D.class, new Long(1615));
But it failed with the message:
Object with id: 1618 was not of the specified subclass: C (loaded object was of wrong class)
Indeed, the object with id 1618 had "B" in the discriminator field and database record corresponded to B instance.

Key: HB-406
Summary: graph loading breaks on complex hierarchies
Type: Bug
Status: Unassigned
Priority: Major
Project: Hibernate2
Components:
core
Versions:
2.0.3
Assignee:
Reporter: Andrey Volozin
Created: Thu, 16 Oct 2003 9:57 AM

Environment: Pentium IV 2.40 GHz, Windows XP, JDK 1.3
Description:
I have a relatively complex hierarchy of objects:
A is common superclass
B, C, D are subclasses
D incapsulates collections of B and C
here is my hbm.xml file:
<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC
"-//Hibernate/Hibernate Mapping DTD//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-2.0.dtd">
<hibernate-mapping>
<class name="A">
<id name="id">
<generator class="hilo">
<param name="table">hi_value</param>
<param name="column">next_value</param>
<param name="max_lo">100</param>
</generator>
</id>
<discriminator column="class_name"/>
<property name="f1"/>
<subclass name="B">
<property name="f2"/>
</subclass>
<subclass name="C">
<property name="f3"/>
</subclass>
<subclass name="D">
<set name="lnkB" cascade="all">
<key column="d_id"/>
<one-to-many class="B"/>
</set>
<set name="lnkC" cascade="all">
<key column="d_id"/>
<one-to-many class="C"/>
</set>
<property name="f4"/>
</subclass>
</class>
</hibernate-mapping>
here are the classes:
public abstract class A {
private Long id;
private String f1;
public Long getId() { return id; }
public void setId(Long id) { this.id = id; }
public String getF1() { return f1; }
public void setF1(String f1) { this.f1 = f1; }
}
public class B extends A {
private String f2;
public String getF2() { return f2; }
public void setF2(String f2) { this.f2 = f2; }
}
public class C extends A {
private String f3;
public String getF3() { return f3; }
public void setF3(String f3) { this.f3 = f3; }
}
public class D extends A {
private String f4;
private Collection lnkB;
private Collection lnkC;
public String getF4() { return f4; }
public void setF4(String f4) { this.f4 = f4; }
public Collection getLnkB() { return lnkB; }
public void setLnkB(String lnkB) { this.lnkB = lnkB; }
public String getLnkC() { return lnkC; }
public void setLnkC(String lnkC) { this.lnkC = lnkC; }
}
I persisted data to the database using the following code:
public class TestMain {
static Session session;
static SessionFactory sessionFactory;
public static Collection createB() throws HibernateException, SQLException {
Collection results = new HashSet();
B b = new B();
b.setF2("foo");
results.add(b);
b = new B();
b.setF2("bar");
results.add(b);
return results;
}
public static Collection createC() throws HibernateException, SQLException {
Collection results = new HashSet();
C c = new C();
c.setF3("foo");
results.add(c);
c = new C();
c.setF3("bar");
results.add(c);
return results;
}
public static D createD(Collection b, Collection c) throws HibernateException, SQLException {
D d = new D();
d.setF1("foo");
d.setLnkB(b);
d.setLnkC(c);
session.save (d);
System.out.println ("Persisting D");
return d;
}
public static void main(String[] args) {
D d;
try {
sessionFactory = new Configuration().configure().buildSessionFactory();
if (sessionFactory == null) { System.out.println ("null session factory returned"); return; }
System.out.println ("Got Session Factory");
session = sessionFactory.openSession();
Collection b = createB();
Collection c = createC();
d = createD(b, c);
session.flush();
session.connection().commit();
System.out.println ("Committing");
session.close();
} catch (MappingException e){
System.out.println (e);
} catch (HibernateException e) {
System.out.println(e);
}
catch (Throwable e) {
System.out.println (e);
e.printStackTrace();
}
}
}
then I started my application again but instead of persistence I did retrieval (I looked up id of D instance in the database):
D d = (D) session.load(D.class, new Long(1615));
But it failed with the message:
Object with id: 1618 was not of the specified subclass: C (loaded object was of wrong class)
Indeed, the object with id 1618 had "B" in the discriminator field and database record corresponded to B instance.

Body:
I came across the same problem using SAPDB 7.4. I think it should either return null or a character. But what happens now is that I get a java.lang.StringIndexOutOfBoundsException. It is now not possible to use character type's if a value in the database can be null.

As the cache region is defined only by the class name, the cache is not able to differentiate instances of the same class with the same id in different databases. I have made a patch for Hibernate 2.0.3 which just add a new parameter 'cache-region-prefix' in the session factory configuration and it works perfectly. As the caching system is completely being refactored, it would be really cool if this simple fix was included in the refactoring. Thanks.

This is expected behavior!
set inherit="false" on stuff you don't want to "bubble down" to other elements.

Here is an overview of the issue:
---------------------------------------------------------------------
Key: HB-403
Summary: hbm2java- Composite-element inherits "extends" meta attribute from class.
Type: Bug
Status: Closed
Priority: Critical
Resolution: REJECTED
Project: Hibernate2
Components:
toolset
Fix Fors:
2.1
Versions:
2.0.3
Assignee: Max Rydahl Andersen
Reporter: Jason Stiefel
Created: Wed, 15 Oct 2003 12:28 PM
Updated: Wed, 15 Oct 2003 2:13 PM
Environment: JDK 1.4
Description:
When using hbm2java a composite-element inherits the parent class "extends" meta attribute. For example, the class generated for the composite-element below will extend "LifecycleSupport" for some reason. :-)
<hibernate-mapping>
<class name="com.pwc.us.factiva.entity.Newsfeed" table="EXTRA_NEWSFEED">
<meta attribute="extends">com.pwc.us.factiva.entity.LifecycleSupport</meta>
....
<list name="selectedMetadata" table="EXTRA_NEWSFEED_METADATA" cascade="none" lazy="true">
<key column="NEWSFEED_ID"/>
<index column="INDEX"/>
<composite-element class="com.pwc.us.factiva.entity.MetadataSelection">
<parent name="newsfeed"/>
<property name="condition" type="com.pwc.us.factiva.entity.ConditionType" column="CONDITION_TYPE"/>
<many-to-one name="metadata" column="METADATA_ID" class="com.pwc.us.factiva.entity.Metadata"/>
</composite-element>
</list>
</class>
</hibernate-mapping>
