Hi All:

I have used reveng.xml to generate DAO and VO Code for my Hibernate and Struts 1.2 Application within Eclipse 3.2 Using JBoss Hibernate Plugins.

However, my DAO Code is Useless as the following fails:

protected SessionFactory getSessionFactory()
{
try
{

return (SessionFactory) new InitialContext().lookup("java:comp/env/hibernate/SessionFactory");
}
catch (Exception e)
{
log.error("********Could not locate SessionFactory in JNDI", e);

}

return null;
}


I get the Following Exception:

SEVERE: ********Could not locate SessionFactory in JNDI
javax.naming.NoInitialContextException: Need to specify class name in environment or system property, or as an applet parameter, or in an application resource file: java.naming.factory.initial
at javax.naming.spi.NamingManager.getInitialContext(NamingManager.java:645)
at javax.naming.InitialContext.getDefaultInitCtx(InitialContext.java:247)
at javax.naming.InitialContext.getURLOrDefaultInitCtx(InitialContext.java:284)

at com.dict.dao.WordMasterHome.getSessionFactory(WordMasterHome.java:36)
at com.dict.dao.WordMasterHome.<init>(WordMasterHome.java:29)


The following is my 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">

<property name="hibernate.session_factory_name">java:comp/env/hibernate/SessionFactory</property>
<property name="hibernate.bytecode.use_reflection_optimizer">false</property>
<property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property>
<property name="hibernate.connection.password">root</property>
<property name="hibernate.connection.url">jdbc:mysql://localhost:3306/dictionary</property>
<property name="hibernate.connection.username">root</property>
<property name="hibernate.default_schema">dictionary</property>
<property name="hibernate.dialect">org.hibernate.dialect.MySQLDialect</property>
<mapping resource="com/dict/dao/PartOfSpeechMaster.hbm.xml" />
<mapping resource="com/dict/dao/MeaningMaster.hbm.xml" />
<mapping resource="com/dict/dao/WordMaster.hbm.xml" />
</session-factory>
</hibernate-configuration>


which was also generated using the Plugins.

I am not able to get a Sessin Factory. This is so puzzling. Do I need a context.xml in META_INF or what ????

All help is appreciated.

Thanks.

What server are you running this in? If you're using Tomcat, you won't be able to manage the SessionFactory using JNDI because the tomcat JNDI implementation is read-only. In that case, remove the jndi line from your config file and build it manually. Very simple to do and very well documented.

Dear Mr. cbredsen:

Thanks for your Kind Reply.

Yes I am using Tomcat 5.5

So do you mean to say I should comment the following from hibernate.cfg.xml

<property name="hibernate.session_factory_name">java:comp/env/hibernate/SessionFactory</property>

As for building it manually, will you pls direct me to resources where I can do so.

As this later part is a little Unclear to me.

Thanks

Yes that line needs to go. Hibernate will attempt to bind itself there and it will fail. You also won't be able to lookup SessionFactory in JNDI. This section of the docs will help you greatly:
