binding SessionFactory to JNDI with WebLogic

jmikres · **Posted:** Wed Sep 17, 2003 2:00 am

i was running thru the forum and also thru the documentation trying to get a handle on how to bind the SessionFactory to JNDI. It seems as though by doing this:

SessionFactory factory = new Configuration().configure().buildSessionFactory();

will bind it because of the values in the hibernate.cfg.xml file. However, I don't see this happening. I also saw a post where someone else was doing a Startup class in WebLogic to bind it to JNDI. I also thought of having an HibernateInit servlet that would create the SessionFactory and bind it to JNDI. Can someone clue me in on if this is necessary, if hibernate does actually do the bind for you, etc. Again I'm on Weblogic 8.1 .

Regards,

They must have broken that somewhere between 6.1 and 8.1 because it works fine for me. Are you sure it is not getting published, or are you looking it up incorrectly?
My cfg.xml:

Code:

<hibernate-configuration>
  <session-factory name="hibernate.session-factory.Oracle">
    <property name="jndi.class">weblogic.jndi.WLInitialContextFactory</property>
    <property name="jndi.url">t3://127.0.0.1:7001</property>
    <!-- irrelevant properties deleted -->
  </session-factory>
</hibernate-configuration>

I create the Session Factory in the (almost) the same way. Then retrieve it with:

Code:

InitialContext initialContext = new InitialContext();
SessionFactory sf = (SessionFactory) initialContext.lookup("hibernate.session-factory.Oracle");

(Simplified, of course)

Do you see any entries like this in your logs?

Code:

01:56,563  INFO SessionFactoryImpl:132 - building session factory
01:56,583  INFO NamingHelper:26 - JNDI InitialContext properties:{java.naming.provider.url=t3://127.0.0.1:7001,

01:57,945  WARN SessionFactoryObjectFactory:101 - InitialContext did not impement EventContext

Especially the "Bound factory..." message.

FYI I am using Weblogic 8.1 and binding to the JNDI tree works fine through the hibernate.cfg.xml.

Below is a snippet from my config file if it helps:

Code:

<property name="connection.datasource">myDataSource</property>
<property name="show_sql">true</property>
<property name="dialect">net.sf.hibernate.dialect.OracleDialect</property>
<property name="jndi.class">weblogic.jndi.WLInitialContextFactory</property> 
<property name="jndi.url">t3://127.0.0.1:7001</property>

only way I could get the session factory into jndi was by manually binding it in weblogic 8.1

Please see this thread. Excuse the cross-post.

With binding the SessionFactory to JNDI in weblogic you don't need hibernate.jndi.url and hibernate.jndi.class to be specified in the manner as you all have in this topic. Those values are the defaults used by weblogic for the initial context(as per e-docs on bea site). So, you only need to specify those if you have another configuration such as a different ip or wish to implement your own class.

Otherwise, you should have no problems binding the session factory once you give your session factory a name in the hibernate config and execute SessionFactory sess = new Configuration().configure().buildSessionFactory();

The configure() is key as it is what actually causes the hibernate config to be read. I spent several hours missing the configure() method.

GOod luck

is this error still exist within weblogic 9.2 m2 ? I'm facing an error with the following config

Code:

<!-- Hibernate session factory -->
   <bean id="annotedSessionFactory"
      class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
      <property name="dataSource">
         <ref bean="datecDataSourcej" />
      </property>
      <property name="hibernateProperties">
         <props>
            <!--
               <prop
               key="hibernate.dialect">org.hibernate.dialect.HSQLDialect</prop>
            -->
            <prop key="hibernate.dialect">org.hibernate.dialect.SQLServerDialect</prop>
            
            <prop key="hibernate.hbm2ddl.auto">update</prop>

...
<bean id="datecDataSourcej" class="org.springframework.jndi.JndiObjectFactoryBean">

and I got this
