Hi pals here,
I encounter lazy initialization problem of Hibernate.
I have set zk.xml according to small talk "ZK + Hibernate", http://www.zkoss.org/smalltalks/hibernatezk/hibernatezk.dsp

zk.xml
<!-- Configure the Hibernate SessionFactory Lifecycle. -->
<listener>
<description>Hibernate SessionFactory Lifecycle</description>
<listener-class>org.zkoss.zkplus.hibernate.HibernateSessionFactoryListener</listener-class>
</listener>

<!-- Configure the Hibernate "Open Session In View" Session Lifecycle -->
<listener>
<description>Hibernate "Open Session In View" Session Lifecycle</description>
<listener-class>org.zkoss.zkplus.hibernate.OpenSessionInViewListener</listener-class>
</listener>

<!-- Hibernate thread session context handler -->
<listener>
<description>Hibernate thread session context handler</description>
<listener-class>
org.zkoss.zkplus.hibernate.HibernateSessionContextListener
</listener-class>
</listener>

hibernate.cfg.xml
<property name="show_sql">true</property>
<property name="format_sql">true</property>
<property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property>
<property name="hibernate.connection.password">hr</property>
<property name="hibernate.connection.url">jdbc:mysql://localhost/hr</property>
<property name="hibernate.connection.username">hr</property>
<property name="hibernate.default_schema">hr</property>
<property name="hibernate.dialect">org.hibernate.dialect.MySQLDialect</property>
<!-- Bind the getCurrentSession() method to the thread. -->
<property name="hibernate.current_session_context_class">thread</property>
<!-- Hibernate's transaction factory -->
<property name="transaction.factory_class">org.hibernate.transaction.JDBCTransactionFactory</property>

My all DAO class all extends Spring's HibernateDaoSupport.

public abstract class AbstractDAO extends HibernateDaoSupport{
public void saveOrUpdate(Object obj) {

getHibernateTemplate().saveOrUpdate(obj);
}

public void delete(Object obj) {
getHibernateTemplate().delete(obj);
}
}

I have tried, if I use getHibernateTemplate() to query, I will get "lazy initialization.. session closed" problem.
But, if I use getSession().createQuery() to query, it works normally.

so, it means I can't use getHibernateTemplate() with ZK?
what's the reason?

Thanks for help.
