This chapter will explain how to install Hibernate and other
associated packages to prepare a develop environment for the Hibernate
applications. We will work with MySQL database to experiment with
Hibernate examples, so make sure you already have setup for MySQL
database. For a more detail on MySQL you can check our
MySQL Tutorial.
Downloading Hibernate:
It is assumed that you already have latest version of Java is
installed on your machine. Following are the simple steps to download
and install Hibernate on your machine.
- Make a choice whether you want to install Hibernate on Windows,
or Unix and then proceed to the next step to download .zip file for
windows and .tz file for Unix.
- Download the latest version of Hibernate from http://www.hibernate.org/downloads.
- At the time of writing this tutorial I downloaded hibernate-distribution-3.6.4.Final and when you unzip the downloaded file it will give you directory structure as follows.
Installing Hibernate:
Once you downloaded and unzipped the latest version of the Hibernate
Installation file, you need to perform following two simple steps. Make
sure you are setting your CLASSPATH variable properly otherwise you will
face problem while compiling your application.
- Now copy all the library files from /lib into your CLASSPATH, and change your classpath variable to include all the JARs:
- Finally copy hibernate3.jar file into your CLASSPATH. This
file lies in the root directory of the installation and is the primary
JAR that Hibernate needs to do its work.
Hibernate Prerequisites:
Following is the list of the packages/libraries required by Hibernate
and you should install them before starting with Hibernate. To install
these packages you would have to copy library files from
/lib into your CLASSPATH, and change your CLASSPATH variable accordingly.
