Ok, Now in a project we have the tables created in a database server. How can i leverage those tables to generate my hibernate pojos or domain objects easily?
a. Install Hibernate Tools.
b. Go to Hibernate Perspective (Window -> Open Perspective -> Other -> Hibernate)
c. In the Hibernate Configurations View, Right click -> Add Configuration
d. Under Main Tab,
* Select the project where the POJOS need to be generated.
* Select the database connection as Hibernate Configured Connection.
* Create the hibernate Configuration file (Properties file is not mandatory) with the following values.
<?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">
<hibernate-configuration>
<session-factory name="TechFes">
<property name="hibernate.connection.driver_class">org.hsqldb.jdbcDriver</property>
<property name="hibernate.connection.url">jdbc:hsqldb:hsql://localhost:9001/TechFes</property>
<property name="hibernate.connection.username">SA</property>
<property name="hibernate.dialect">org.hibernate.dialect.HSQLDialect</property>
</session-factory>
</hibernate-configuration>
e. Now go to Run icon (the run icon in Hibernate perspective) and click on Hibernate Code Generation Configurations.
f. Under Main Tab,
* Select the output directory where the files has to get generated.
* Select the "Reverse Engineer from JDBC Connection" checkbox.
* Check the Domain Code, hibernate cfg file and if required annotations, etc.
h. Click on Run and your domain code should have got generated.

* Select the "Reverse Engineer from JDBC Connection" checkbox.
* Provide the package name under which the domain java objects need to be created.
* Uncheck "Detect many-to-many" associations. This will help in generating the pojo objects for the tables that are maintained only for many-many association.
g. Under Exporters Tab,* Uncheck "Detect many-to-many" associations. This will help in generating the pojo objects for the tables that are maintained only for many-many association.
* Check the Domain Code, hibernate cfg file and if required annotations, etc.
h. Click on Run and your domain code should have got generated.
