I’m new to hibernate and I’m trying to use the JNDI DAO that is generated by myeclipse. I can’t seem to setup hibernate correctly to use WebLogic JNDI. Please help.

my hibernate.cfg.xml
————————-
<?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”&gt;

<!– Generated by MyEclipse Hibernate Tools. –>
<hibernate-configuration>

<session-factory>
<property name=”dialect”>org.hibernate.dialect.OracleDialect</property>
<property name=”jndi.url”>t3://localhost:7001</property>
<property name=”jndi.class”>weblogic.jndi.WLInitialContextFactory</property>
<property name=”connection.datasource”>orcl-milemarker-jdbc</property>
<mapping resource=”com/autotrader/milemarkers/reports/Reports.hbm.xml” />

</session-factory>

</hibernate-configuration>

I keep getting the error below:

Did you actually go into the WebLogic administration console and setup the JNDI data source to point at your database?

[closec1]

Yes the datasource was setup previously. I’m trying to convert the application to use hibernate. I know this probably isn’t the correct forum for this issue but I’m stuck and just shooting in the dark for any answers.

[Riyad Kalla]

Your JNDI url doesn’t make sense… if your app server is hosting up your data source under JNDI, then it will look something like java:/comp/env/jdbc/weblogic or something like that…

Have a look here for more help: http://www.hibernate.org/hib_docs/v3/reference/en/html/session-configuration.html#configuration-optional-jndi

[lambo82669]

you must call “new Configuration().configure().buildSessionFactory()” in order to have the sessionfactory register itself with the weblogic jndi context.

Hello, tell me please Where do you call “new Configuration().configure().buildSessionFactory()” in the DAO class or HibernateSessionFactory

[Haris Peco]

jguatemala,

It is called :

– HibernateSessionFactory#rebuildSessionFactory()
– in Spring DAO it is called with Spring – Spring have session factory bean
– in Base DAO it is called in BaseHibernateDAO (call HibernateSessionFactory)
– in JNDI DAO you have to make session factory JNIDI in your application server
