PDF Viewer as a JPanel in a NetBeans RCP Application

The project I'm working on is run by a book publishing company in Sweden. So for them to want to be able to provide integrated support for PDF viewing in the product seemed fairly obvious. After spending quite some time googling for different derivatives of "open source pdf jpanel swing" and such, I first found PdfRenderer, an original SwingLabs project that seemed to not be worked on at that time (but perhaps will be restarting soon? Keep an eye on that link if you're interested, I know I will).

There are multiple options if you're looking for commercially licensed products and, what seem like, good ones too. But I wanted open source. After a while I found http://www.icepdf.org and it seemed like their mozilla public licensed ICEpdf project offered what I was looking for.

What I wanted was fairly simple. I had a pdf file and wanted a viewer panel extending JPanel.

And voila, this is how my code ended up looking:

import org.icepdf.ri.common.SwingController;
import org.icepdf.ri.common.SwingViewBuilder;

InputStream inputStream = MY_PDF_AS_STREAM;
SwingController controller = new SwingController();
SwingViewBuilder factory = new SwingViewBuilder(controller);
JPanel viewerComponentPanel = factory.buildViewerPanel(); 
MY_MAIN_PANEL.add(viewerComponentPanel, BorderLayout.CENTER);
controller.openDocument(inputStream, "", "");

And this is what I got, in our NetBeans RCP application:
