SessionFactory problem

Question

Hi everyone. Here is my situation :<br />b I have a class named UserHome generated by HibernateTool which contain briefly this :<br /><br />package rdev.data;<br /><br />// Generated 21 oct. 2008 18:08:40 by Hibernate Tools 3.2.1.GA<br />import ...<br /><br />/**<br /> * Home object for domain model class User.<br /> * @see rdev.data.User<br /> * @author Hibernate Tools<br /> */<br />public class UserHome {<br />]private static final Log log = LogFactory.getLog(UserHome.class);<br /><br />]private final SessionFactory sessionFactory = getSessionFactory();<br /><br />]protected SessionFactory getSessionFactory() {<br />]]try {<br />]]]return (SessionFactory) new InitialContext()<br />]]]]].lookup("SessionFactory");<br />]]} catch (Exception e) {<br />]]]log.error("Could not locate SessionFactory in JNDI", e);<br />]]]throw new IllegalStateException(<br />]]]]]"Could not locate SessionFactory in JNDI");<br />]]}<br />]}<br /><br />]public void persist(User transientInstance) {}<br /><br />]public void attachDirty(User instance) {}<br /><br />]public void attachClean(User instance) {}<br /><br />]public void delete(User persistentInstance) {}<br /><br />]public User merge(User detachedInstance) {}<br /><br />]public User findById(java.lang.Integer id) {}<br /><br />]public List findByExample(User instance) {}<br /><br />}<br /><br />b I have created a custom class which inherit from this USerHome class :<br /><br />package rdev.dao;<br /><br />import ...<br /><br />public class UserDAO extends UserHome{<br />]public List<User> findAll()<br />]{<br />]]Session session = HibernateUtil.getSessionFactory().getCurrentSession();<br />]]session.beginTransaction();<br />]]List<User> l = userHome.findByExample(new User());<br />]]return l;<br />]}<br />]<br />]public List<User> getOnlineUser()<br />]{<br />]]Session session = HibernateUtil.getSessionFactory().getCurrentSession();<br />]]session.beginTransaction();<br />]]User u = new User();<br />]]u.setStatus(1);<br />]]List<User> l = userHome.findByExample(u);<br />]]return l;<br />]}<br />]<br />]public String sayKikoo()<br />]{<br />]]return "Kikoo !";<br />]}<br /><br />}<br /><br />b I have configured a remote service in the remoting-config.xml using this last class :<br /><br /><service id="remoting-service" <br />]class="flex.messaging.services.RemotingService"><br />]<adapters><br />]]<adapter-definition id="java-object" class="flex.messaging.services.remoting.adapters.JavaAdapter" default="true"/><br />]</adapters><br /><br />]<default-channels><br />]]<channel ref="my-amf"/><br />]</default-channels><br />]<br />]<destination id="user"><br />]]<properties><br />]]]<source>rdev.dao.UserDAO</source><br />]]]<scope>application</scope><br />]]</properties><br />]</destination><br /><br /></service><br /><br />b The problem that I get, is when i'm starting Tomcat and is reaching the destination "user" in loading process I get this error :<br /><br />[BlazeDS] MessageBroker with id '__default__' is starting.<br />[BlazeDS] MessageBroker id: __default__ classLoader is: the MessageBroker's class loader and the context class loader (classLoader hashCode: 11688861 (parent hashCode: 17517359 (parent system))<br />[BlazeDS] Service with id 'authentication-service' is starting.<br />[BlazeDS] Service with id 'authentication-service' is ready (startup time: '0' ms)<br />[BlazeDS] Service with id 'remoting-service' is starting.<br />21 oct. 2008 22:15:03 rdev.data.UserHome getSessionFactory<br />GRAVE: Could not locate SessionFactory in JNDI<br />javax.naming.NameNotFoundException: Le Nom SessionFactory n'est pas lié à ce Contexte<br />   at org.apache.naming.NamingContext.lookup(NamingContext.java:770)<br />   at org.apache.naming.NamingContext.lookup(NamingContext.java:153)<br />   at org.apache.naming.SelectorContext.lookup(SelectorContext.java:137)<br />....<br /><br />"Le Nom SessionFactory n'est pas lié à ce Contexte" could be translated in :<br />"The SessionFactory Name is not linked to this Context"<br /><br />I have inherited UserDAO from UserHome because I believed it's the cleanest way to use the generated method from Hibernate.<br />If i removed it, the start process works fine but I'll need to instanciate a new UserHome everytime i would want to do a database operation.<br />How could I avoid instanciate it everytime and get my Tomcat starting properly ? I hope i'm clear enough. <br />Regards.

Hi. I think you need to change the class generated by hibernate to not initialize the sessionFactory variable when the class gets instanciated.
private final SessionFactory sessionFactory = getSessionFactory();
I don't think there is a way to get the behavior you want without changing the code.
