org.hibernate.HibernateException: No Session found for current thread

getCurrentSession() only makes sense inside a scope of transaction. You need to declare an appropriate transaction manager, demarcate boundaries of transaction and perform data access inside it. For example, as follows: <bean id = “transactionManager” class = “org.springframework.orm.hibernate4.HibernateTransactionManager”> <property name = “sessionFactory” ref = “sessionFactory” /> </bean> . PlatformTransactionManager ptm = context.getBean(PlatformTransactionManager.class); TransactionTemplate tx = … Read more

“Found: bit, expected: boolean” after Hibernate 4 upgrade

I worked this out by adding columnDefinition = “BIT” to the @Column line. @Basic @Column(name = “B”, columnDefinition = “BIT”, length = 1) public boolean isB() { return b; } Its defined as a ‘BIT(1)’ in the DB as well. Also worked with TINYINT. This is the easiest solution I’ve found since the change is … Read more

Hibernate : No CurrentSessionContext configured

As per the best of my knowledge, your configuration is not proper for current session. Instead of <property name=”hibernate.current_session_context_class”>org.hibernate.context.ThreadLocal‌​SessionContext</property> use <property name=”hibernate.current_session_context_class”>thread</property> For more information on this, please visit this link: http://docs.jboss.org/hibernate/orm/3.3/reference/en/html/architecture.html#architecture-current-session Specially, read the last lines of last paragraph. For those who’re using Hibernate 4.1, <property name=”hibernate.current_session_context_class”>org.hibernate.context.internal.ThreadLocalSessionContext</property> Reference: https://docs.jboss.org/hibernate/orm/4.1/javadocs/org/hibernate/context/internal/ThreadLocalSessionContext.html

Getting error Could not locate appropriate constructor on class

This exception happens because JPA doesn’t change column types returned from the database for native queries. Because of this, you have type mismatch. I’m not sure about which column causes this problem in your case (this depends on DBMS you use), but I would suspect you have BigInteger in the result set instead of Integer … Read more

NoSuchMethodError in javax.persistence.Table.indexes()[Ljavax/persistence/Index

I’ve ran into the same problem. The question here is that play-java-jpa artifact (javaJpa key in the build.sbt file) depends on a different version of the spec (version 2.0 -> “org.hibernate.javax.persistence” % “hibernate-jpa-2.0-api” % “1.0.1.Final”). When you added hibernate-entitymanager 4.3 this brought the newer spec (2.1) and a different factory provider for the entitymanager. Basically … Read more

How do you configure logging in Hibernate 4 to use SLF4J

Look to https://github.com/jboss-logging/jboss-logging/blob/master/src/main/java/org/jboss/logging/LoggerProviders.java: static final String LOGGING_PROVIDER_KEY = “org.jboss.logging.provider”; private static LoggerProvider findProvider() { // Since the impl classes refer to the back-end frameworks directly, if this classloader can’t find the target // log classes, then it doesn’t really matter if they’re possibly available from the TCCL because we won’t be // able to find … Read more
