Starting with Spring 3.0, many features provided by the Spring JavaConfig project became part of the core Spring Framework. Thus, you can define beans external to your application classes by using Java rather objects (DAOs), presentation objects such as Struts Action instances, infrastructure objects such as Hibernate SessionFactories, JMS Queues, and so forth. Typically, one does not configure fine-grained domain

s "refresh()" method, for hot refreshing in concurrent environments Package org.springframework.core * fixed JdkVersion to properly detect JDK 1.6/1.7 (Java 6/7) as higher than 1.5 (Java 5) * fixed 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

get wrapped in outer exceptions with appropriate context information Package org.springframework.core * refined Jdk13ControlFlow to be compatible with GNU ClassPath (whose stacktrace has a whitespace enable proper batching in all cases * Hibernate LocalSessionFactoryBean exposes its DataSource on "SessionFactory.close()", for potential schema export * Hibernate LocalSessionFactoryBean offers protected LocalSessionFactoryBean for Hibernate3, allowing to load multiple config files * added "replicate" convenience methods to HibernateTemplate for both Hibernate2 and Hibernate3 * added BlobStringType with

eagerly, for message defined in parent and msg arg defined in child Package org.springframework.core * refined NestedXxxException to properly handle null message in root cause, through using the cause's NativeJdbcExtractorAdapter to retry with DatabaseMetaData Connection if extraction failed (for Hibernate 3.1) * turned JdbcTemplate's "query(PreparedStatementCreator,PreparedStatementSetter,ResultSetExtractor "updateDatabaseSchema" to declare the correct exception (DataAccessException) * fixed BlobStringType for Hibernate2/3 to correctly handle SQL NULL Package org.springframework.remoting * RmiClientInterceptorUtils

AbstractMessageSource, allowing for custom processing of default msgs Package org.springframework.core * unified path normalization in ClassPathResource, FileSystemResource, UrlResource and ServletContextResource resource description but not pointing to a readable resource * added EncodedResource class to package "core.io.support", combining a Resource with an encoding to use for reading * added StaticLabeledEnum, "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

CGLIB-overridden bean properties as eligible for dependency checking too Package org.springframework.core * refactored AbstractPathResolvingPropertyEditor into SystemPropertyUtils.resolvePlaceholders(text) SessionFactoryUtils converts Hibernate3's StaleStateException into Spring's OptimisticLockingFailureException too * added "findByExample" methods to HibernateOperations/Template for Hibernate3, for querying by example loader, if any, as bean class loader to the XmlBeanDefinitionReader Package org.springframework.core * added "setClassLoader" method to DefaultResourceLoader, also exposed on AbstractApplicationContext

loader, if any, as bean class loader to the XmlBeanDefinitionReader Package org.springframework.core * added "setClassLoader" method to DefaultResourceLoader, also exposed on AbstractApplicationContext recently published version of the Hibernate 3.0.5 jar (there seem to be multiple versions around) * added "findByCriteria" methods to HibernateOperations/Template for Hibernate3, for executing DetachedCriteria DefaultMessageSourceResolvable constructor that accepts a single code String Package org.springframework.core * added ByteArrayResource adapter, useful for example to create mail attachments from local content
