Updated DAO code generation as discussed over the email
-------------------------------------------------------
Key: HBX-733
URL: http://opensource.atlassian.com/projects/hibernate/browse/HBX-733
Project: Hibernate Tools
Type: Patch
Components: hbm2java, ant
Versions: 3.1alpha5
Environment: I have tested the patch on the latest version of Hibernate Tools I got from SVN 2 weeks ago.
Reporter: Alex Kalinovsky
Attachments: dao_generation.patch
This should be a complete implementation of DAO generation according to the design we have discussed over the email. I've tested this on our project so the DAOs should be good to go, but of course a more diverse testing would be needed before releasing it to public. I'm open for recommendations and suggestions, so I see this as the first draft. Below is a list of files and comments. Contact me at kalinovsky(a)yahoo.com.
src/java/org/hibernate/tool/hbm2x
DAONewExporter.java This class is coded mainly to accept additional parameters such as dao package name and provide flexible
file naming that is used by Ant task. It would not be needed if I integrate my changes into GenericExporter.
src/templates/dao
crudDao.ftl template for regeneratable CRUD interface
crudDaoImpl.ftl template for regeneratable CRUD DAO implementation
dao.ftl template for customizable DAO interface that extends CRUD interface
daoImpl.ftl template for customizable DAO implementation that extends CRUD implementation

dao.ftl base interface for all DAOs

[Hibernate-JIRA] Created: (HHH-2016) Oracle9Dialect registers last_day() function as "lastday"
by Carl Lindberg (JIRA)
Oracle9Dialect registers last_day() function as "lastday"
---------------------------------------------------------
Key: HHH-2016
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2016
Project: Hibernate3
Type: Bug
Components: core
Versions: 3.0 alpha, 3.0 beta 1, 3.0 beta 2, 3.0 beta 3, 3.0 beta 4, 3.0 rc 1, 3.0 final, 3.0.1, 3.0.2, 3.0.3, 3.0.4, 3.0.5, 3.1 beta 1, 3.1 beta 2, 3.1 rc 1, 3.1 rc2, 3.1 rc3, 3.1, 3.1.1, 3.1.2, 3.2.0.alpha1, 3.2.0.alpha2, 3.1.3, 3.2.0 cr1, 3.2.0.cr2, 3.2.0.cr3
Environment: Hibernate 2.x, 3.x with an Oracle database
Reporter: Carl Lindberg
Priority: Minor
Attachments: Oracle9DialectPatch.diff, Oracle9DialectPatchOption2.diff
Oracle9Dialect.java registers a "lastday" function, however the actual Oracle function is last_day() (with the underscore). This results in a SQL error if the function is used in HQL (and obviously, HQL will not accept use of "last_day").
The patch is basically:
- registerFunction( "lastday", new StandardSQLFunction("lastday", Hibernate.DATE) );
+ registerFunction( "last_day", new StandardSQLFunction("last_day", Hibernate.DATE) );
or, if support for the incorrect "lastday" usage should still be supported:
- registerFunction( "lastday", new StandardSQLFunction("lastday", Hibernate.DATE) );
+ registerFunction( "last_day", new StandardSQLFunction("last_day", Hibernate.DATE) );
+ registerFunction( "lastday", new StandardSQLFunction("last_day", Hibernate.DATE) );
Both patch options are attached.

[Hibernate-JIRA] Created: (ANN-438) Merging annotations and XML sometimes causes an XML parser error
by James Telfer (JIRA)
Merging annotations and XML sometimes causes an XML parser error
----------------------------------------------------------------
Key: ANN-438
URL: http://opensource.atlassian.com/projects/hibernate/browse/ANN-438
Project: Hibernate Annotations
Type: Bug
Versions: 3.2.0.cr1
Environment: Hibernate 3.2 CR2, SQL Server 2005
Reporter: James Telfer
I created a class and annotated it with EJB 3 annotations, then created an XML descriptor to store my named queries. The XML I used is excerpted below. I then added the mapping file to my cfg.xml as a <mapping resource=""/%gt; element. When Hibernate was configured, it threw the parser exception included below also.
The same error occurred when configuring my application within Tomcat (via Spring). To narrow down the problemI created a very simple class to configure Hibernate and ran that in Eclipse. This worked. The line used to configure Hibernate was: <code>new AnnotationConfiguration().configure(new File("hibernate.cfg.xml")).buildSessionFactory();</code>.
Eclipse is running on Windows using the JDK 1.5.07 Server VM with parallel GC and the Eclipse runner used the JDK server VM with standard GC. Tomcat was using the JRE 1.5.07 client VM. I changed the VM used by Tomcat and it succeeded. Hibernate Tools still fails to read the configuration file.
If any further information is required, I'd be happy to provide it. There is a forum thread (http://forum.hibernate.org/viewtopic.php?p=2310540&sid=f14052739a96c418c3...) that describes a similar problem, but the user's fix is not feasible in this scenario.

[Hibernate-JIRA] Created: (HHH-2000) CLONE -merge() with one-to-one throws ClassCastException
by Marco Rothe (JIRA)
CLONE -merge() with one-to-one throws ClassCastException
--------------------------------------------------------
Key: HHH-2000
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2000
Project: Hibernate3
Type: Bug
Components: core
Versions: 3.1 beta 2
Reporter: Marco Rothe
Hibernate tries to bind a persistent object to a long variable in a SQL statement during a call to merge() on an object with a one-to-one relation.
I originally posted about this problem here: http://forum.hibernate.org/viewtopic.php?t=948272&highlight=
I have created and attached a junit test to reproduce the problem. When running against 3.0 or 3.1beta2 the ClassCastException is thrown all the way out, as shown in the forum post. The latest code from cvs catches the exception and logs it. org.hibernate.type.NullableType.java rev 1.10 is where the exception is caught. It seems like it should be logged and then re-thrown, but it's not. The debug log from the start of the merge() call to where it logs that it failed to bind the value is:
[junit] 11:12:32,461 DEBUG SessionImpl:271 - opened session at timestamp: 11283595524
[junit] 11:12:32,461 DEBUG JDBCTransaction:54 - begin
