Download the distribution binary

Download Benerator from:

You should download the most recent version of the rapiddweller-benerator-dist archive from the download page, e.g. .

Unzip Benerator

Unzip the downloaded file in an appropriate directory, e.g. /Developer/Applications or C:\Program Files\Development.


Create an environment variable BENERATOR_HOME that points to the path you extracted benerator to.

Windows Details: Open the System Control Panel, choose Advanced Settings - Environment Variables. Choose New in the User Variables section. Enter BENERATOR_HOME as name and the path as value ( e.g. C:\Program Files\Development\rapiddweller-benerator-ce-1.1.2). Click OK several times.

Mac/Unix/Linux Details: Open the file .profile in your user directory. Add an entry that points to benerator, e.g.: export BENERATOR_HOME=/Developer/Applications/rapiddweller-benerator-ce-1.0.0

Optional: Install JDBC drivers

Benerator comes with open source JDBC drivers (for connecting to a database). No extra installation is necessary for them:

• Microsoft SQL Server Driver (MS SQL Server)

• MySQL Connector


• H2 DB

• Derby Client

• PostgreSQL

• Jaybird (Firebird DB)

However, if you need to use a closed source database driver, the vendor usually requires you to accept usage conditions before you can download and install their driver. So, if you are using Oracle DB or DB2, get the JDBC drivers from these sites:

• Oracle Click on "Oracle Database 11g Release 2 ( drivers". Download ojdbc6.jar and put it into Benerator's lib directory. You will need to create a free Oracle account.

• DB2 Follow the link 'IBM Data Server Driver for JDBC and SQLJ', download the driver archive and copy the contained file db2jcc.jar to Benerator's lib directory.

Optional: Set up log4j2

Troubleshooting is simpler if you make use of log4j's configuration capabilities. If you do not know (or care) about logging, simply skip this step. Otherwise put a custom log4j2.xml file into the BENERATOR_HOME/lib directory.

On Unix/Linux/Mac systems: Set permissions

Open a shell on the installation's root directory and execute

chmod a+x bin/*.sh

Mac OS X configuration

On Mac OS X you need to provide benerator with an explicit configuration of the JAVA_HOME path. See for a good introduction to the OS X way of setting up Java. It is based on aliases conventions. If you are not familiar with that, you should read the article. If Java 6 (or newer) is the default version you will use, you can simply define JAVA_HOME by adding the following line to your .profile: in your user directory:

export JAVA_HOME=/Library/Java/Home

If it does not work or if you need to use different Java versions, it is easier to 'hard-code' JAVA_HOME like this:

export  JAVA_HOME=/Library/Java/JavaVirtualMachines/adoptopenjdk-11.jdk/Contents/Home/ 

Verifying the settings

On any OS, open a console window (shell,cmd or powershell) and type ...

$ benerator -–version

Benerator 1.1.2-jdk-11 build 1
Java version 11.0.9
JVM OpenJDK 64-Bit Server VM 11.0.9+11 (AdoptOpenJDK)
OS Linux 5.9.16-050916-generic (amd64)

// Benerator will then launch and print out version information about itself, 
// the Java version it uses, the operating system.
