Oracle LONG datatype fetching fails on superclass Criteria query
----------------------------------------------------------------
Key: HHH-3395
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3395
Project: Hibernate3
Issue Type: Bug
Environment: Oracle 10
Windows XP
Hibernate 3
Weblogic 9.2
Reporter: Ville Anttonen
I have dao-layer method like this.
public PersistentQuery getPersistentQuery(String userId, long queryId){
....
Criteria criteria = m_session.createCriteria(PersistentQuery.class);
criteria.add(Expression.eq("userId",userId));
criteria.add(Expression.eq("id",new Long(queryId)));
return (PersistentQuery) criteria.uniqueResult();
.....
}
Previous code throws "Stream already closed" exception.
PersistentQuery is abstract class
and it's subclasses contains UserType - field
that wraps Oracle's long varchar field.
I can fix this by creating criteria by subclass
like " Criteria criteria = m_session.createCriteria(PersistentOrganizationQuery.class); ".
We're migrating from ingres -> oracle and in ingres previous implementation worked fine.

[Hibernate-JIRA] Created: (HHH-3406) IndexOutOfBoundsException when a flush occurs during validation inside a flush

IndexOutOfBoundsException when a flush occurs during validation inside a flush
------------------------------------------------------------------------------
Key: HHH-3406

Say we have entity A:
@Entity
public class A {
[...]
@AssertTrue
public boolean validateSomeCondition(){
//call service S
B=S.loadEntityB()
[.... do some stuff with B...]
}
}
In my hibernate session I modifiy several entities among them A1, A2, A3 (instances of A), then I flush the session that firsts validates A1. Inside A1.validateSomeCondition() I have to call a service that loads some data inside its own transaction, thus when it returns a commit is triggered that is intercepted an hibernate flushes its session, and not only entities bound to this transaction but the WHOLE session (including A2, A3 !!!). Then validation of A1 finishes successfully and A1 is saved to db, but right after that this exception occurs

I do not really know if flushing A2,A3 entites inside the 2nd flush is an issue or not (I do not mind actually...), so I suggest this quick fix:
inside ActionQueue method
private void executeActions(List list)
throws HibernateException
{
int size = list.size();
for(int i = 0; i < size; i++)
execute((Executable)list.get(i));
list.clear();
session.getBatcher().executeBatch();
}
replace the "static" int size = list.size(); for(int i = 0; i < size; i++) by an iterator...
thx

[Hibernate-JIRA] Created: (HHH-2679) One to Many Unidirectional Association using Join Tables and <list> causes duplicate key constraint violation when an entry is deleted from the list.
by Priyajeet Hora (JIRA)
One to Many Unidirectional Association using Join Tables and <list> causes duplicate key constraint violation when an entry is deleted from the list.
-----------------------------------------------------------------------------------------------------------------------------------------------------
Key: HHH-2679
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2679
Project: Hibernate3
Issue Type: Bug
Components: core
Affects Versions: 3.2.2
Environment: Java 1.5, Hibernate 3.2, MySQL 5. Might also effect NHibernate similarly.
Reporter: Priyajeet Hora
Priority: Critical
Consider this unidirectional one-to-many relation done using join tables.
Person --> Address (*).
The hibernate mapping is pretty much the same as
http://www.hibernate.org/hib_docs/v3/reference/en/html/associations.html#...
Though I am using <list> rather than a <set>
Following is the DDL (presented roughly) created by the hbm2ddl tool.
Table PersonAddress
Person_id varcahr not null
Address_id varchar not null unique
Person_list_index integer not null
primary key (Person_id, Person_list_index)
I create a person1 - person_id=1.
I create add1, add2, add3 - address_id=2,3,4 respectively.
then I add all 3 addresses to the list in person1.
persist it to database.
all good.
At this point in the database --
person_id---person_list_index---address_id
1--0--2
1--1--3
1--2--4
I get person1 back.
I remove add1.
save person1 back.
CONSTRIANT VIOLATION HERE DUE TO DUPLICATE KEY.
looking at what hibernate does ...
So after 1st save and before remove this is whats in the database -
person_id---person_list_index---address_id
1--0--2
1--1--3
1--2--4
basically shows the one to many there.
I want to remove the record no. 1--0--2. That is the 1st one.
So with the 1st row gone, hibernate needs to shift other records up so that the new list index is assingned.
expected output----
1--0--3
1--1--4
This is how hibernate proceeds
Step1: save info and delete on 1--2--4, to get rid of that last record.
Step2: update 1--0--2 to 1--0--3
BANG...CONSTRAINT VIOLATION DUE TO DUPLICATE KEY.
Why? because "3" in that address_id column is already there and that column is "unique" according to DDL.
Step3: update 1--0--3 to info saved from step1, that is to 1--1--4.
But cant persist this since step 2 fails.
Basically the algorithm of copy the value up when a delete is performed is not doing the copy correctly.
Way to get around this is to remove the "unique" constrint, but then that makes the relation a many to many.
-----------------------------------------------------------------------------

No information about Person, since this is a unidirectional association.
Target doesnt know about the source.

The generated SQL (show_sql=true):
Hibernate: insert into Parent (id, name) values (null, ?)
Hibernate: call identity()
Hibernate: insert into Child (id, name, parent_fk) values (null, ?, ?)
Hibernate: call identity()
Hibernate: select parent0_.id as id0_0_, parent0_.name as name0_0_ from Parent parent0_ where parent0_.id=?
Hibernate: select children0_.parent_fk as parent3_1_, children0_.id as id1_, children0_.id as id1_0_, children0_.name as name1_0_, children0_.parent_fk as parent3_1_0_ from Child children0_ where children0_.parent_fk=?
Why is this exception thrown under these circumstances? Am I using the API in an undocumented/disallowed way? If yes, where exactly?
The Hibernate API doc says, that Session.get() returns null if an object can't be found. No exception should be thrown.
However, Session.get() at the end of sample code does return null as expected, if either
a) Session.get() is used instead of load() some lines above (see commented line)
b) the transaction and the session is isn't closed or reopened, respectively
c) Session.flush() is called before the final call to Session.get()
I'd like to understand why Hibernate behaves like this, which I presume is erroneous. I'm a beginner in Hibernate, but I couldn't get any help in the forum.

[Hibernate-JIRA] Created: (HHH-3159) Oracle 11g - desupport of oracle.jdbc.driver
by D. S. (JIRA)
Oracle 11g - desupport of oracle.jdbc.driver
--------------------------------------------
Key: HHH-3159
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3159
Project: Hibernate3
Issue Type: Bug
Components: core
Affects Versions: 3.2.5
Environment: Hibernate 3.2.5GA, Oracle 11.1.0.6.0.
Reporter: D. S.
With Oracle 11g, the deprecated package oracle.jdbc.driver no longer exists and this causes issues with all OracleDialect classes making it impossible to use Hibernate.
This issue affects all of the following classes:
Oracle9iDialect.java
Oracle9Dialect.java
Oracle10gDialect.java
The line error in question is:
Class types = ReflectHelper.classForName("oracle.jdbc.driver.OracleTypes");
This simply needs to be changed to:
Class types = ReflectHelper.classForName("oracle.jdbc.OracleTypes");
>From the Oracle 11g readme.txt
"In Oracle JDBC release 9.0.1 customer use of the classes
in that package was deprecated. A new package, oracle.jdbc, was
introduced and customers were advised to begin using the
interfaces and classes defined in oracle.jdbc. In every release
since 9.0.1 we have encouraged customers to switch to oracle.jdbc
and stated that oracle.jdbc.driver would be desupported. The time
has come. Customer code that references oracle.jdbc.driver will
not compile and will not execute in this and future releases of
the Oracle JDBC drivers. Please use oracle.jdbc instead."
Thanks.

Query results are mapped to object array incorrectly when there is column ambiguity and aliases are not used
------------------------------------------------------------------------------------------------------------
Key: HHH-2575
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2575
Project: Hibernate3
Issue Type: Bug
Components: query-sql
Affects Versions: 3.2.2
Environment: Hibernate 3.2.2 + MySQL 5.0.22 + MySQL Connector/J 5.0.5. Reproduced with HSQLDB 1.8.0.7.
Reporter: Mike Hoeffner
Priority: Minor
Attachments: ResultsNotEffectedByAliasesTest.java
I had a SQL (not HQL) query that basically looked like this:
select a.name, a.seq, b.name, b.seq from foo a, foo b;
and I noticed that the results obtained through list() -> (Object[]) get(i) -> row[0], row[1], row[2], row[3]
did not correspond to what I saw when manually running the query without Hibernate involved. row[2] always had the same values as row[0] and row[3] always had the same values as row[1].
When I tried adding aliases so that it became:
select a.name as a_name, a.seq as a_seq, b.name as b_name, b.seq as b_seq from foo a, foo b;
then the results matched what I expected. So having aliases in the SQL modified the results that were returned even though I was looking up the value from each column by its index / position instead of by its name / alias.
Attached is a test case that will reproduce this.

Second-level cache is used after Session.setCacheMode(CacheMode.IGNORE)
-----------------------------------------------------------------------
Key: HHH-2661
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2661
Project: Hibernate3
Issue Type: Bug
Components: caching (L2)
Affects Versions: 3.2.4.sp1
Environment: Windows Vista
MySQL 5.0
Reporter: Anders Wallgren
I'm doing some bulk importing and want to disable the L2 cache, so I call Session.setCacheMode(CacheMode.IGNORE) before doing any work.
However, the entities I'm creating still end up in the cache. It seems that org.hibernate.action.CollectionAction isn't doing the correct check to determine when to cache -- it only check for the existence of a configured cache, but doesn't check whether caching is enabled in the session.
For example, from CollectionAction.beforeExecutions:
public final void beforeExecutions() throws CacheException {
// we need to obtain the lock before any actions are
// executed, since this may be an inverse="true"
// bidirectional association and it is one of the
// earlier entity actions which actually updates
// the database (this action is resposible for
// second-level cache invalidation only)
if ( persister.hasCache() ) {
final CacheKey ck = new CacheKey(
key,
persister.getKeyType(),
persister.getRole(),
session.getEntityMode(),
session.getFactory()
);
lock = persister.getCache().lock(ck, null);
}
}
Shouldn't "if ( persister.hasCache() )" be persistence.hasCache && getSession.getCacheMode.isPutEnabled(), or something along those lines?
