Thanks for the response. 

I am using *maven-hibernate3-plugin 2.2*, which has a dependency on *hibernate-tools  3.2.3.GA* and *hibernate-core 3.3.1.GA* 

Here is some output from running the following command:

$ *mvn -X hibernate3:hbm2java*

hibernate.connection.url=*jdbc:oracle:thin:@*****
hibernate.connection.username=****
hibernate.connection.password=****
hibernate.dialect=*org.hibernate.dialect.Oracle10gDialect*
hibernate.default_schema=*MY_SCHEMA*

and the following reverse enginerring file:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-reverse-engineering PUBLIC 
  "-//Hibernate/Hibernate Reverse Engineering DTD 3.0//EN" 
  "http://hibernate.sourceforge.net/hibernate-reverse-engineering-3.0.dtd" >
