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.
