Spring IOC + hibernate

Rick Evans : hi Rick, I didn't know it but as you can see in my hibernate.cfg.xml file, I've defined a "current_session_context_class" but the problem still remains. Is it correct ?

The hibernate.cfg.xml file :

<?xml version='1.0' encoding='utf-8'?>
<!DOCTYPE hibernate-configuration PUBLIC
        "-//Hibernate/Hibernate Configuration DTD 3.0//EN"
        "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">
<hibernate-configuration>

    <session-factory>
        <!--MySQL JDBC Driver connection -->
        <property name="connection.driver_class">com.mysql.jdbc.Driver</property>
        <property name="connection.url">jdbc:mysql://localhost/maDB</property>
        <property name="connection.username">root</property>
        <property name="connection.password">test</property>
        <property name="dialect">org.hibernate.dialect.MySQL5Dialect</property>

        <!-- JDBC connection pool (use the built-in) -->
        <property name="connection.pool_size">1</property>

        <!-- Enable Hibernate's automatic session context management -->
        <property name="current_session_context_class">org.hibernate.context.JTASessionContext</property>

        <!-- Disable the second-level cache  -->
        <property name="cache.provider_class">org.hibernate.cache.NoCacheProvider</property>

        <!-- Echo all executed SQL to stdout -->
        <property name="show_sql">true</property>

        <mapping resource="com/company/countryApp/bo/Country.hbm.xml"/>

    </session-factory>
</hibernate-configuration>

However, I'll follow your recommendations for the use of HibernateTemplate instead of working directly with the SessionFactory…

sixtiesman, i'm having the same problem trying to use plain hibernate3 api in my daos, and found no solution yet. i raised this question again at

http://forum.springframework.org/showthread.php?t=42297

i think it's important to continue this issue because i've seen various references to this same problem, which leads me to think if the spring documentation might be missing something.

hi dazen6

I'm not a J2EE expert but I never managed to implement the "plain hibernate3 api" in my DAO's. I've not been helped (I'm a student and I did it during a traning period) and I gave up this idea after hours !

The problem only disappeared when I used the "HibernateTemplate" class instead of the "SessionFactory" class provided by Hibernate and I handled the transactions the declarative way.

I really advise you to do this but I really would be curious to know how we can solve this an other way.

good luck dazen6 !
