For doing this, we need OpenOffice installed, and the service started. Get the latest version of OpenOffice and install it.

After installing, we may need to start the OpenOffice service. This can be done by navigating to the folder where OpenOffice is installed (for example, C:\Program Files\OpenOffice.org 3\program) from the console, and issuing the following command:

soffice -headless -accept=”socket,host=127.0.0.1,port=8100;urp;” -nofirststartwizard

This should start up OpenOffice as the service running on port 8100.

Log in to Liferay using admin credentials.

Navigate to Control Panel by clicking on Manage | Control Panel from the dock bar.

Click on the Server Administration from the bottom-left, and then click on OpenOffice, as shown in the following screenshot:

Check Enabled and click on Save.
