[Hibernate-JIRA] Commented: (ANN-390) Property pointed to by "mappedBy" not found if defined in superclass of class referenced by "targetType"

by Adrian Sampaleanu (JIRA)

[ http://opensource.atlassian.com/projects/hibernate/browse/ANN-390?page=co... ] Adrian Sampaleanu commented on ANN-390: --------------------------------------- Our situation is 3, and I see your point - the bi-directional mapping we had was not correct from that point of view so Hibernate's message was accurate, although it might be worded a bit more clearly to indicate that it wasn't found in the targetEntity (in our case that was DeploymentTaskImpl).

[Hibernate-JIRA] Created: (HHH-2029) default value for hibernate.connection.release_mode is not correct

by Pavel Rubin (JIRA)

default value for hibernate.connection.release_mode is not correct ------------------------------------------------------------------ Key: HHH-2029 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2029 Project: Hibernate3 Type: Bug Components: documentation Versions: 3.2.0.cr3 Reporter: Pavel Rubin Priority: Minor The docs (http://www.hibernate.org/hib_docs/v3/reference/en/html/session-configurat...) says that default value for hibernate.connection.release_mode is "on_close". But in the source code (3.2.0.cr3) we can see, the default is "auto", which is either "after_transaction" or "after_statement" depending on the TransactionFactory. See: org.hibernate.cfg.SettingsFactory line 168, org.hibernate.transaction.JDBCTransactionFactory line 19, org.hibernate.transaction.JTATransactionFactory line 61. See also issue #HHH-1038 Either the docs or defaults should be changed. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://opensource.atlassian.com/projects/hibernate/secure/Administrators.... - For more information on JIRA, see: http://www.atlassian.com/software/jira
