In the hibern8ide installation instructions, it says the you can add the hibern8ide.jar to a hibernate enabled project within eclipse.

Can someone tell me exactly what a hibernate enabled project is. I am trying to use this tool and since my datasource is configured in tomcat through jndi, I need to use this tool inside my web application environment. I have read through some postings and searched on google, but I can't find anything that will tell me step by step how to integrate this tool in tomcat.

If anybody has accomplished this, I would appreciate it if you could explain to me how you got this to work.

Thanks in advance

Create your sessionfactory and call



And a hibernate enabled project is just a project in which you already have configured hibernate...

Okay I tried that but since my datasource is configured through jndi in tomcat, hibern8ide can't find my datasource.

I made sure tomcat is running when I tried to start it.

Any more suggestions???

Try launching HibernateIDE from within a Servlet :)

The following solution works for Tomcat 4.0.3 ...

It shouldn't matter what your IDE is ...

I have the following hibernate.cfg.xml file. Note the property for
connection.provider_class :


<?xml version='1.0' encoding='utf-8'?>
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD 2.0//EN"

"http://hibernate.sourceforge.net/hibernate-configuration-2.0.dtd">

<hibernate-configuration>

<session-factory>
<property name="connection.provider_class">com.rhi.bob.common.dao.HibernateConnectionProvider</property>
<property name="dialect">net.sf.hibernate.dialect.OracleDialect</property>
<property name="show_sql">true</property>
<property name="transaction.factory_class">net.sf.hibernate.transaction.JDBCTransactionFactory</property>
<property name="hibernate.cache.provider_class">net.sf.hibernate.cache.HashtableCacheProvider</property>
<property name="hibernate.hbm2ddl.auto">update</property>
<mapping resource="com/rhi/bob/webfo/forms/beans/impl/FormImpl.hbm.xml"/>
</hibernate-configuration>


And this class,HibernateConnectionProvider,
to establish a DB connection vi JNDI :

package com.rhi.bob.common.dao;

import java.sql.Connection;
import java.sql.SQLException;
import java.sql.Statement;
import java.util.Properties;

import javax.naming.InitialContext;
import javax.naming.NamingException;
import javax.naming.Context;
import javax.sql.DataSource;

import net.sf.hibernate.HibernateException;
import net.sf.hibernate.connection.ConnectionProvider;

public class HibernateConnectionProvider implements ConnectionProvider
{
private static final String DATASOURCE = "java:comp/env/jdbc/RFDSRef";
private String dsName;
private DataSource ds;

public void configure( Properties props ) throws HibernateException {
dsName = DATASOURCE;
try {
Context ctx = new InitialContext();
ds = (DataSource)ctx.lookup( DATASOURCE );
} catch ( NamingException nx ) {
System.out.println(nx.getMessage());
throw new HibernateException( nx.getMessage());
}
if ( this.ds == null ) {
String msg = "invalid hibernate source specified : " + this.dsName;
System.out.println( msg );
throw new HibernateException( msg );
}
}
public Connection getConnection() throws SQLException {
return this.ds.getConnection();
}

public void closeConnection( Connection con ) throws SQLException {
con.close();
}

public void close() throws HibernateException {
System.out.println( "shutting down hibernate source : " + this.dsName );
}

}
