Error:No Hibernate Session bound to thread, and configuration does not allow creation of non-transactional one here

To solve this problem. You have to do two things:

1. mark the DAO as transactional or function which is doing database call like:

  @Transactional
   public class EmployeeDaoImpl  extends DaoImpl implements EmployeeDao{
 /////
}
           OR
@Transactional
    public long addEmployee(Employee employee) {
        System.out.println("Employee:"+employee );
        long id = employeeDao.addEmployee(employee);
        System.out.println("Id1: " );
        return id;
    }


2. Enable the annotation driven transcation management in applicationContext.xml (where your beans are defined):


<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p"
    xmlns:tx="http://www.springframework.org/schema/tx"
    xmlns:context="http://www.springframework.org/schema/context"
    xsi:schemaLocation="http://www.springframework.org/schema/beans
    http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
    http://www.springframework.org/schema/aop
    http://www.springframework.org/schema/aop/spring-aop.xsd
    http://www.springframework.org/schema/tx
    http://www.springframework.org/schema/tx/spring-tx.xsd
    http://www.springframework.org/schema/context
    http://www.springframework.org/schema/context/spring-context-3.0.xsd">
<!-- Main transaction manager for accessing internal DB -->
    <bean id="transactionManager"
        class="org.springframework.orm.hibernate3.HibernateTransactionManager">
        <property name="sessionFactory" ref="sessionFactory" />
    </bean>
   
    <!-- enable the configuration of transactional behavior based on annotations -->
  <tx:annotation-driven transaction-manager="transactionManager"/>

That's it. Hope it works for other too.
