Integration of OpenOffice into native Java Swing application wanted

We have developed a Java Swing application based on Java 6 Update 26 which allows to create and store documents. We currently use a java editor component and want to replace this editor buy embedding OpenOffice into our application so that users can seamlessly work with documents retrieved from our database system and edit them wit OpenOffice. Since we cannot expect users to have OpenOffice installed, we would like to integrate OpenOffice such that it is delivered as part of our application setup. There would be no need to install OpenOffice so that users can use it independently from our application. Therefore, OpenOffice can be setup to be only used programmatically from within our application. If you have experience to embed OpenOffice in a Java Swing application, then please let us know to refine requirements. Kind regards, Peter
