[Hibernate-JIRA] Created: (ANN-594) Filters for MappedSuperClass
by Shawn Clowater (JIRA)
Filters for MappedSuperClass
----------------------------
Key: ANN-594
URL: http://opensource.atlassian.com/projects/hibernate/browse/ANN-594
Project: Hibernate Annotations
Issue Type: New Feature
Components: binder
Affects Versions: 3.3.0.ga
Reporter: Shawn Clowater
Priority: Minor
Based on discussion from
http://forum.hibernate.org/viewtopic.php?t=963539&start=0
Essentially, it would be nice to be able to define filters on a MappedSuperClass and have them 'trickle down' to the subclasses. (at the class level - not sure if property level filters are carried down right now).
I see the MappedSuperClass as a means to define generic behaviour (common columns, etc) and I think it makes sense for the filters to play nicely as well.
In addition, I don' t know if it is already a separate JIRA request, filters off of an Interface would be fantastic as well as our application is using filters heavily and are always looking at ways to reduce the amount of filter annotations that we have to spread around.
Right now, we're either forced to copy filter annotations all over the place OR we've actually been a bit sneaky and have tapped into custom persisters to dynamically apply common filters. However, there is a separate issue based on the order that entity persisters are built.

[Hibernate-JIRA] Created: (HHH-2412) Hibernate 3 cannot be compiled under JDK 6

Hibernate 3 cannot be compiled under JDK 6
------------------------------------------
Key: HHH-2412
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2412
Project: Hibernate3
Type: Task
Components: core
Versions: 3.2.1, 3.2.2
Environment: windows xp, JDK 6
Reporter: Ahmet A. Akin
Hibernate code cannot be compiled under JDK 6. Problems and possible solutions:
1- org.hibernate.jdbc.ResultSetWrapper implements ResultSet. But in Java 6, there are big changes in Resultset interface, and maybe 20+ more methods needs to be implemented in the ResultSetWrapper class. i would suggest eliminating this wrapper class once and for all, because it is only used in one method (in ColumnNameCache, getIndexForColumnName method) and i dont think there is a justification for using that wrapper class.
2- org.hibernate.lob.SerializableBlob needs to implement new Blob interface methods:
public void free() throws SQLException;
public InputStream getBinaryStream(long pos, long length) throws SQLException
But, if this class is publicly accesible or used by API's back compatibility issues needs to be checked.
3- Same as number 2, org.hibernate.lob.BlobImpl class needs to implement new Blob methods.
4- org.hibernate.lob.SerializableClob class needs to implent new Clob methods.
5- org.hibernate.lob.ClobImpl , same as 4.
In fact, Java 6 has a lot of JDBC improvements, maybe a java6 special extra package can be created., but that is a whole different issue.

Reporter: John Newman
If I use a @MappedSuperclass (which is a very useful annotation btw) I have to manually copy any queries I want with taht class up to all subclasses. The binder should check any mapped superclasses and pull those named queries up. i.e.
/**
* Base User class that different projects user classes derive from.
* Hibernate annotations doesn't pick up that query, so you have to copy it up to your subclass
*/
@MappedSuperclass
@NamedQueries({
@NamedQuery(name="User.findByLoginName",
query="FROM User WHERE loginName = ?") // this is useless down here, i just put it here for reference
})
public class BaseUser<PK extends Serializable> extends IdEntity<PK> {
private static final long serialVersionUID = -4443522925041212381L;
protected String loginName;
@Column(unique=true)
public String getLoginName() {
return this.loginName;
}
public void setLoginName(String loginName) {
this.loginName = loginName;
}
}
/**
* Custom user class for a certain application
*/
@Entity
@Table(name="tbl_user")
@GenericGenerator(name=IdGen.NAME, strategy=IdGen.AUTO)
@NamedQueries({
@NamedQuery(name="User.findByLoginName",
query="FROM User WHERE loginName = ?") // had to copy this up from the base class
})
public class User extends BaseUser<Short> {
private static final long serialVersionUID = -6199544722824321999L;
private String firstName;
...
}
so in short it would be nice if the scanner would check for that and bind any named queries up to the subclass

Joins break when using composite primary key classes
JBoss 4.0.5.GA w/ Hibernate 3.2.2 and Annoations 3.2.2 (from SVN). Also reproduced w/ JBoss 4.0.5.GA w/ stock annotations, hibernate, and entity manager, unmodified. The attached test-case was run against MSSQL 2000 but is trivial to point at another database. The issue was also reproduced on a OpenEdge Progress 10.1A database.
In a case where there are composite keys on one (or each) side of a relationship, Hibernate cannot join the entities together if all of the primary key fields are not used in the relationship.
A (very) simple example, two entities Carz and Lotz (pardon the names, it's simply cars and car lots):
@Entity
@Table(name="car")
public class Carz implements Serializable
{
@Id
private Integer id;
@Column(name="make", nullable=false)
private String make;
@Column(name="model", nullable=false)
private String model;
@Column(name="manufactured", nullable=false)
@Temporal(TemporalType.TIMESTAMP)
private Date manufactured;
@ManyToOne(fetch=FetchType.LAZY)
@JoinColumns //Hibernate docs state that @JoinColumns must be used since Lotz has composite PK, a single @JoinColumn does not deploy anyhow
({
@JoinColumn(name="loc_code", referencedColumnName="loc_code", insertable=false, updatable=false)
})
private Lotz lot;
...........................
}
@Entity
@Table(name="lot")
public class Lotz implements Serializable
{
@EmbeddedId
protected LotzPK lotPK;
@Column(name="name", nullable=false)
private String name;
@Column(name="location", nullable=false)
private String location;
@OneToMany(mappedBy="lot", fetch=FetchType.LAZY, cascade=CascadeType.ALL)
private List<Carz> cars;
...........................
}
@Embeddable
public class LotzPK implements Serializable
{
@Column(name="id", nullable=false)
private Integer id;
@Column(name="loc_code", nullable=false)
private String locCode;
...........................
}
In this case I need a one-to-many relationship on Carz.id = Lotz.locCode. However, there doesn't appear to be a way to do this.
When this is deployed, this exception occurs:
org.hibernate.AnnotationException: Column name id of hqb.model.Lotz not found in JoinColumns.referencedColumnName

...........................
I can deploy the app if I map both fields in the Lotz PK class like so:
@Entity
@Table(name="car")
public class Carz implements Serializable
{
@Id
private Integer id;
...........................
@ManyToOne(fetch=FetchType.LAZY)
@JoinColumns
({
@JoinColumn(name="loc_code", referencedColumnName="loc_code", insertable=false, updatable=false),
@JoinColumn(name="", referencedColumnName="id", insertable=false, updatable=false) //INCORRECTLY DEFINED RELATIONSHIP!
})
private Lotz lot;
...........................
}
But obviously this is no good, it generates bad SQL at runtime:
/* select
c
from
Carz c
left join
fetch c.lot */ select
carz0_.id as id198_0_,
lotz1_.id as id199_1_,
lotz1_.loc_code as loc2_199_1_,
carz0_.make as make198_0_,
carz0_.model as model198_0_,
carz0_.manufactured as manufact4_198_0_,
carz0_.lot_id as lot5_198_0_,
carz0_.loc_code as loc6_198_0_, --no such column...
lotz1_.name as name199_1_,
lotz1_.location as location199_1_
from
car carz0_
left outer join
lot lotz1_
on carz0_.lot_id=lotz1_.id --oops! Hibernate defaulted a relationship here...
and carz0_.loc_code=lotz1_.loc_code
In reality, this is the SQL I'm trying to achieve, by repairing the above query manually:
select
carz0_.id as id198_0_,
lotz1_.id as id199_1_,
lotz1_.loc_code as loc2_199_1_,
carz0_.make as make198_0_,
carz0_.model as model198_0_,
carz0_.manufactured as manufact4_198_0_,
carz0_.loc_code as loc6_198_0_,
lotz1_.name as name199_1_,
lotz1_.location as location199_1_
from
car carz0_
left outer join
lot lotz1_
on carz0_.loc_code=lotz1_.loc_code
This is consistent w/ the EJB 3.0 spec (and Glassfish+Toplink) but that's only because the spec doesn't define exacltly how to handle this. However, that being said, this seems important enough for Hibernate to be able to manage?

[Hibernate-JIRA] Created: (HHH-2401) CLOB truncation on DB2 when using 2 or 3 byte chars (UTF8)
by Simon Jongsma (JIRA)
CLOB truncation on DB2 when using 2 or 3 byte chars (UTF8)
----------------------------------------------------------
Key: HHH-2401
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2401
Project: Hibernate3
Type: Bug
Components: core
Versions: 3.2.0.ga
Environment: Hibernate 3.2.0 GA + JBoss 4.0.4.GA on Windows XP + DB2 UDB for ISeries V5R3 + IBM JT Open driver 4.9
Reporter: Simon Jongsma
Priority: Minor
Attachments: ClobTruncated.zip
A CLOB column is used in DB2 mapped to a String in Java with the Hibernate "Text" mapping.
The column in DB2 has a CCSID 1208 which means "UTF8" (= Unicode).
The CLOB truncation occurs when characters are used that are UTF8 coded in more than one byte.
In that the string is truncated when persisted in the database.
For example the string
"Granpré Molière†; 0123456789". This string has three diacritical marks in it.
The é and è are coded in two bytes in UTF8 and the † in three bytes.
This string will be stored as "Granpré Molière†; 012345".
So "6789" is not stored.
It appears as though Hibernate does not take into account that a character can be more than 1 byte in UTF8.
The number of missing char's at the end is exactly: string.getBytes("UTF-8").length minus string.length()
It is not a problem of DB2 or the JT Open driver:
Storing and retrieving (from a Java program) the same String directly via Jdbc into the DB2 table and retrieving it, works 100% fine.
So this clearly points to a problem somewhere in Hibernate.
