[Hibernate-JIRA] Created: (HV-248) Validator should be aware of nested beans
by Ken Egervari (JIRA)
Validator should be aware of nested beans
-----------------------------------------
Key: HV-248
URL: http://opensource.atlassian.com/projects/hibernate/browse/HV-248
Project: Hibernate Validator
Issue Type: New Feature
Affects Versions: 4.0.0.CR1
Reporter: Ken Egervari
Priority: Critical
When using the Bean validation listener with Hiberante, I think the property path should be aware of nested beans.
For example, let's say we have a Customer which contains a User object. Both of these objects have validation constraints on them, however, Customer is the top-level one.
Now, if we are to save this Customer bean to hibernate with cascades, and there is an error on the User object on the field 'emailAddress', the constraint's property path is merely 'emailAddress'.
I think this really limits what people can do with the exceptions that you are giving away, as it is very possible that the customer object also has an email address.
I realize you are giving people access to the class and target object, but what if the objects that are contained are the same type?
The right solution to this problem is the give the correct property path. In this case, the property path should really be "user.emailAddress". It should be self-aware that the user was cascaded by the customer object.
I would consider this to be critical, but as it is, it is not easy to get translate the exceptions to the Spring MVC's error handling, which requires the full path (and that makes PERFECT sense in this application).
As it stands, all forms must only edit 1 bean at a time - no components or many-to-one relationships will work.
Thanks for listening

[Hibernate-JIRA] Created: (HBX-1145) Warning message "The transaction remains active, [..]" at the end of the hbm2java ant task
by Julien Kronegg (JIRA)
Warning message "The transaction remains active, [..]" at the end of the hbm2java ant task
------------------------------------------------------------------------------------------
Key: HBX-1145
URL: http://opensource.atlassian.com/projects/hibernate/browse/HBX-1145
Project: Hibernate Tools
Issue Type: Bug
Components: ant, hbm2java
Affects Versions: 3.2.2
Environment: Hibernate Tools 3.2.2.GA, DB2, Seam 2.1.2.GA/seam-gen, http://anonsvn.jboss.org/repos/hibernate/branches/Branch_3_2/HibernateExt..., http://anonsvn.jboss.org/repos/hibernate/core/trunk/core/src/main/java/or...
Reporter: Julien Kronegg
Priority: Minor
When doing a hbm2java ant task to generate entities from the database, an exception occurs when closing the connection pool if transactions are used.
INFO: cleaning up connection pool: jdbc:db2://192.168.17.12:8801/TES1
org.hibernate.connection.DriverManagerConnectionProvider close
WARNING: problem closing pooled connection
Throwable occured: com.ibm.db2.jcc.b.SqlException: ... java.sql.Connextion.close() requested while a transaction is in progress on the connection.
The transaction remains active, and the connection cannot be closed. ERRORCODE=-4471, SQLSTATE=null
... // obfuscated calls from com.ibm.db2.jcc.b.*
at org.ibm.db2.jcc.b.jb.close(jb.java:1089)
at org.hibernate.connection.DriverManagerConnectionProvider.close(DriverManagerConnectionProvider:175)
at org.hibernate.cfg.JDBCBinder.readFromDatabase(JDBCBinder:95)
...
at org.hibernate.tool.ant.Hbm2JavaExporterTask.configureExporter(Hbm2JavaExporterTask:43)
This is only a warning and the hbm2java ant task do the Java file generation correctly. However, this warning make think about a problem when generating the entities from the database.
The solution may be to commit/rollback the transaction (if any) before closing the connection pool. This could be done in JDBCBinder.readFromDatabase() or in the DriverManagerConnectionProvider.close() methods.
Workaround:
-----------------
Set the following property in the hibernate properties file used for the ant task:
hibernate.connection.autocommit=true
