sembler operates correctly in case of no "ignoredMethods" specified Package org.springframework.orm * iBATIS support works correctly with "useTransactionAwareDataSource" and JTA transaction resume with since a vendor dialect may support it * Hibernate3 LocalSessionFactoryBean automatically sets JTATransactionFactory if given a "jtaTransactionManager" * Hibernate3 LocalSessionFactoryBean only sets connection not given a "jtaTransactionManager" * Hibernate3 LocalSessionFactoryBean exposes configured DataSource for schema update (required on Hibernate 3.2.1+) * Hibernate3 LocalSessionFactoryBean registers filter

accordingly Package org.springframework.orm * SqlMapClientTemplate always works with SqlMapSession and provided Connection to enable proper batching in all cases * Hibernate LocalSessionFactoryBean exposes its its DataSource on "SessionFactory.close()", for potential schema export * Hibernate LocalSessionFactoryBean offers protected "executeSchemaStatement" method for overriding the failure handling * added LocalSessionFactoryBean for Hibernate3, allowing to load multiple config files * added "replicate" convenience methods to HibernateTemplate for both Hibernate2 and Hibernate3 * added BlobStringType with

NativeJdbcExtractorAdapter to retry with DatabaseMetaData Connection if extraction failed (for Hibernate 3.1) * turned JdbcTemplate's "query(PreparedStatementCreator,PreparedStatementSetter,ResultSetExtractor MockFilterConfig, using a MockServletContext instead of a ServletContext argument Package org.springframework.orm * refined JDO PersistenceManagerFactoryUtils to explicitly suspend pre-bound PM in the course of transaction "updateDatabaseSchema" to declare the correct exception (DataAccessException) * fixed BlobStringType for Hibernate2/3 to correctly handle SQL NULL Package org.springframework.remoting * RmiClientInterceptorUtils

implementations to return null for non-existing resource Package org.springframework.orm * SessionFactoryUtils converts Hibernate3's StaleStateException into Spring's OptimisticLockingFailureException too * * added "findByExample" methods to HibernateOperations/Template for Hibernate3, for querying by example entity object Package org.springframework.remoting * reworked JndiRmiClientInterceptor/ProxyFactoryBean even if info logging is turned off Package org.springframework.orm * upgraded to the most recently published version of the Hibernate 3.0.5 jar (there seem to be multiple versions around) * added "findByCriteria"

requiredType)" method to JndiLocatorSupport, used by JndiObjectFactoryBean Package org.springframework.orm * all "executeFind" operations throw InvalidDataAccessApiUsageException if the result isn't actually "isOpen" assertions to Hibernate Session synchronization, seamlessly removing dangling Sessions (fail-safe) * refined HibernateTransactionManager and SessionFactoryUtils to adapt to Hibernate 3.1's changed Session HibernateTemplate, for parameterizing a Hibernate3 Filter * added "bulkUpdate" convenience operations to HibernateOperations/HibernateTemplate, for Hibernate3 bulk update/delete * fixed HibernateTemplate

even if info logging is turned off Package org.springframework.orm * upgraded to the most recently published version of the Hibernate 3.0.5 jar (there seem to be multiple versions around) * added "findByCriteria" "findByCriteria" methods to HibernateOperations/Template for Hibernate3, for executing DetachedCriteria objects * added "fetchSize" and "maxResults" bean properties to HibernateTemplate, applied to Query editor (e.g. for form objects) Package org.springframework.orm * extended doc coverage regarding plain DAO implementations: based on plain Hibernate3/JDO/TopLink/OJB/iBATIS API * added "allowCreate" flag

trigger persistence problem that was introduced in 1.6.0) * upgraded to Hibernate 3.3.0 (while retaining compatibility with Hibernate 3.1/3.2) * upgraded to iBATIS SQL Maps 2.3.2 (while retaining compatibility MIME type for "css" extension from MimeMessageHelper's default mappings Package org.springframework.orm * improved HibernateTransactionManager's InvalidIsolationLevelException exception message (-> Spr CurrentSessionContext * documented use of Hibernate StatelessSession with Spring's DataSourceTransactionManager/HibernateTransactionManager * added support for Derby and H2 through Hibernate/OpenJpa/TopLink/EclipseL

"deactivate()"+"activate()", with the standard JNDI provider exposed inbetween Package org.springframework.orm * HibernateTemplate detects Spring-managed transactional Session even with SessionFactory proxy and distinct root entities (avoiding duplicate entries in result list) * HibernateTemplate translates Hibernate's DataException into a Spring DataIntegrityViolationException (for consistency) * fixed Hibern "packagesToScan" property to Hibernate AnnotationSessionFactoryBean, for autodetection of @Entity classes * HibernateJpaDialect checks "EntityManager.getDelegate()" as well to find Hibernate Session (for Seam compatibility)
