Hi All
This is Ashwini...

i am working on a project ..in which i have created tables in database
,,& used hibernate reverse engineering to generate related POJO
Classes & DAO classes in eclipse ..


I could generate pojo clases & DAO classes as per tables ..but in DAO
classes i am getting following error


...getCurrentSession() is undefined for the type session factory..


does any one knows why this error should occur ,since this method is of

class
SessionFactory ..all other methods ..like
openSession(),close(),getCollectionMetadate()..are working fine..but it

is saying that getCurrent Session() ..is undefined ..does anyone know
why is so??


early feedback would be of great help ..
Thanks
Ashwini


for more information ..there is one table in Db called Alert ..
i could generate Alert.java pojo class & AlertDAO.java class as bellow
,


Alert.java


/**
* Alert generated by MyEclipse - Hibernate Tools
*/


public class Alert implements java.io.Serializable {


// Fields


private long alertKey;
private Keyword keyword;
private String location;
private String radius;
private String howOften;
private String email;


// Constructors


/** default constructor */
public Alert() {
}


/** minimal constructor */
public Alert(long alertKey, Keyword keyword, String email) {
this.alertKey = alertKey;
this.keyword = keyword;
this.email = email;
}


/** full constructor */
public Alert(long alertKey, Keyword keyword, String location,
String radius, String howOften, String emai


public long getAlertKey() {
return this.alertKey;
}


public void setAlertKey(long alertKey) {
this.alertKey = alertKey;
}


public Keyword getKeyword() {
return this.keyword;
}


other getter setter methods goes here...


AlertDAO.java


package com.Cmpe275Project.hibernate;


import java.util.List;
import javax.naming.InitialContext;
import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;
import org.hibernate.LockMode;
import org.hibernate.SessionFactory;
import org.hibernate.criterion.Example;


/**
* Data access object (DAO) for domain model class Alert.
* @see com.Cmpe275Project.hibernate.Alert
* @author MyEclipse - Hibernate Tools
*/
public class AlertDAO {


private static final Log log = LogFactory.getLog(AlertDAO.class);


private final SessionFactory sessionFactory = getSessionFactory();


protected SessionFactory getSessionFactory() {
try {
return (SessionFactory) new
InitialContext().lookup("src/com.Cmpe275Project.hibernate");
} catch (Exception e) {
log.error("Could not locate SessionFactory in JNDI", e);
throw new IllegalStateException("Could not locate
SessionFactory in JNDI");
}



}


public void save(Alert transientInstance) {
log.debug("saving Alert instance");
try {

sessionFactory.getCurrentSession().saveOrUpdate(transientInstance);
log.debug("save successful");
} catch (RuntimeException re) {
log.error("save failed", re);
throw re;
}
}

It sounds like you've got the wrong version of Hibernate on the
classpath (getCurrentSession is a relatively recent addition to the
API). That being said, this is absolutely the wrong place to ask your
question. You'll do much better at http://forum.hibernate.org/.
