Let's start with the JAR: HibernateN.jar (where N is the version number). Drop this in your lib folder.
You're probably going to need to select a bunch of supporting JARs to go with Hibernate, depending on what options you want. For example:
The basic things to start an application? Hmmm, a stand-alone application. Okay, you've probably read about the XML configuration file - looks a little like this:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-mapping PUBLIC
"-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">
<hibernate-mapping package="myapp">
<class name="Customer" table="app_customer">
<id name="id" type="integer">
<generator class="identity" />
</id>
<property name="name" type="string" />
<list name="orders" cascade="all-delete-orphan">
<key column="_customer" />
<list-index column="order_no" />
<one-to-many class="Order" />
</list>
</class>
</hibernate-mapping>
You also need a Hibernate context XML document. This defines your database (or connection pool) and the XML configuration file you are going to use:
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd">
<beans>

Then you start coding your application.
A really good place to start is the Caveat Emptor example Hibernate application. See
