Open Office Integration with Liferay

Purpose of the Open Office integration is to convert one type of data format to another type
of data format. 
For example I have uploaded one word document into documentLibrary portlet. But I want to 
download the document as pdf. Here in this scenerio openoffice integration comes into the 
picture.
To integrate with Liferay Portal Server please follow the below steps : 

Step 1 :     Install openoffice software into your machine. We can install the software on any OS like windows, MAC, linux.
Step 2 :    Go to the folder where it was installed (for example, C:\Program Files\OpenOffice.org\program) and start OpenOffice service with the following command:
        open cmd and run the below command under above specified path
        soffice -headless -accept="socket,host=127.0.0.1,port=8100;urp;" -nofirststartwizard 
        The above command will be executed irrespective of Operating Systems. 
Step 3 :    Goto Control panel --> Server Category --> Server Administration --> Open Office
Step 4 :     Select check box of Enableed and make sure that port number should be 8100
or
Step 5 :     We can enable the property from portal-ext.properties by providing the property as
        openoffice.server.enabled=true
        openoffice.server.host=//YourServerURL//

Step 6 :     Now you can upload the document into document library and try to download the document in another format.
I hope it will be helpful to  you.
