Introduction to OpenOffice
OpenOffice Extensions
What are extensions
Extensions in OpenOffice extends the capability of the OpenOffice program. Extension can be for OpenOffice Writer, Calc, Presentation, Database or for the core OpenOffice. For OpenOffice writer, there may be extensions that extends the dictionary feature of OpenOffice so that user can use a French dictionary. Similarly there may be extensions that adds extra grammar features. An extension for Calc might do a complex calculation like mortgage calculation or filter data in certain way.
A popular extension might become part of the core program in a future release.
Extensions for OpenOffice can downloaded at http://extensions.services.openoffice.org
How to install extensions
To install an extension
- First download an extension from http://extensions.services.openoffice.org
- Then open OpenOffice Writer or Calc. On the top menu, click Tools->Extension Manager...
- Click Add... and select the .oxt file (extension file) you downloaded.
Usually, you should see a new button or menu item related to the extension you install. Since extension can do different things, sometimes you might not see any button or menu item. That extension might only appear and work on context menu. So if you cannot find it, check the extension's read-me file or manual.

Linux
Install OpenOffice.org and SDK
OpenOffice.org program and SDK can be installed through package manager program, such as apt-get, yum, merge and pacman. Also, several GUI font-end for package manager programs are available to make installation easier. On Ubuntu, Synaptic is good choice. YumEx is the best option on Fedora.
- Ubuntu:
- With aptitude: launch a terminal and enter following command
-
sudo aptitude install openoffice.org openoffice.org-dev
- If you want SDK examples and documentations, install openoffice.org-dev-doc as well.
-
sudo aptitude install openoffice.org-dev-doc
- With Synaptic: Go to menu: System -> Administration -> Synaptic Package Manager. Search openoffice, and click openoffice.org, openoffice.org-dev, openoffice.org-dev packages, then click Mark for Installation and hit Apply on toolbar.
- Fedora:
- With Yum:
-
sudo yum install {package name} - To-Do: replace {package name} with real package names under Fedora
- With YumEx:
- YumEx does not come with distribution. You needed to be installed manually.
-
sudo yum install yumex
- After installation, launch YumEx, search openoffice, select those packages and install.
Note: On Fedora, sudo is not set by default. You can add you account to wheel user group so that you can use sudo. Also, you may use su to change to root, and run yum to install packages.
Note: On Ubuntu, if you use OpenOffice.org program that comes with distribution, and try to install SDK that is downloaded from OpenOffice.org website, you may encounter dependency issue. You should the SDK that come with distribution.
Install NetBean, and OpenOffice.org Extension Development Plugin
NetBean can be installed through package manager as well. Package name is netbeans.
Ubuntu:
sudo aptitude install netbeans
Fedora:
sudo yum install netbeans
To-Do: need someone check if the packages name for Netbeans on Fedora is netbeans.
After installation, you can install development plugin in NetBean. Lunch NetBean, select Plugins under Tool menu. Then switch to Available Plugins tab, and install OOo API plugin. Finally, select Options under Tool menu, and go to Miscellaneous -> OOo API Plugins tab. Fill in the path to OpenOffice.org program and SDK. Path is provide in following section.
Install Eclipse and OpenOffice.org Extension Development Plugin
To-Do: guild on install setup Eclipse for OOo Extension Dev
Path to OpenOffice.org Program and SDK
- Ubuntu:
- Program: /usr/lib/openoffice
- SDK: /usr/lib/openoffice/basis3.2/sdk
- Examples: /usr/lib/openoffice/basis3.2/sdk/example
- Mint:
- Program: /usr/lib/openoffice
- SDK: /usr/lib/openoffice/basis3.1/sdk
- Examples: /usr/lib/openoffice/basis3.1/sdk/example
To-Do: need path on Fedora and others major distros.
Windows
This is tutorial is to set up a Java development platform on Windows.
You will need the following software:
Make sure you install OpenOffice and the SDK before running Netbeans.
First Open Netbeans and go to:
Tools -> Plugins
Go the Available Plugins tab and look for OpenOffice.org API Plugin and check the box beside it.
It will prompt you to install and click the Install button on the bottom of the list.
The plugin will install. To change the setting for the plugin go to:
Tools -> Options -> Miscellaneous -> OOo API Plugin
There you will see the directory path to the installation of both OO and The SDK. If you need to change it then you can make the corrections here.

Factory Pattern Design
OpenOffice.org development heavily uses the Factory method design pattern.
Design patterns are conventional templates that describes how to solve common software problems. Since most developers are familiar with the patterns, they can recognize a pattern in others source code. That makes working in teams easier. There are many popular design patterns. One of them is Factory method pattern.
Factory method pattern is a type of creational pattern. Creational pattern pattern solves problems related to creating. Factory pattern solves two major problem generally faced by developers.
1. To reduce too many new operator usage
- When working on a large software, numerous instances of classes are created continuously at the runtime. The programmer cannot predict what the user is going to do. So at any given time, the programmer doesn't know what object is create. For example, To create a new document, the user might click new text document or new spreadsheet document. There would several possibilities about what the user is going to do. So, a factory class is assigned to do all these repetitive work of creating a new instance of what the user wants. By separating these repetitive object creations into a factory class, when new classes are added, only the factory class need to be updated.
2. To create object without knowing its class name.
- When using the concrete classes, the developer has to remember the class names. In factory pattern, choosing what type of object to be created is delegated to the factory class. Usually this is done by sending a parameter. Based on the parameter passed to the factory, the factory creates an instance of a certain type/class.
public final class DocumentFactory {
XDocument document;
XDocument getDocument(String type){
if(type.equals("text"){
document = new TextDocument();
}
else if(type.equals("sheet"){
document = new SpreadSheet();
}
return document;
}
}
public interface XDocument{
open();
}
public class TextDocument implements XDocument{
//concrete class for Text documents
open(){
//method to open text document
System.out.println("opening a text document...");
}
}
public class SpreadSheet implements XDocument{
//concrete class for spreadsheet documents
open(){
//method to open spreadsheet document
System.out.println("opening a spreadsheet document...");
}
}
class DocumentProgram{
public static void main(String[] args){
XDocument doc = df.getDocument("text"); //this just created an instance of TextDocument without knowing its class name.
doc.open();
}
}
