Puoi postare un pochino di codice (magari di più di quello postato all'inizio)? Da quello iniziale, vedo e capisco solo che stai usando il componente (pannello) di PDFBox per mostrare una pagina.
Questa è la classe che faccio riferimento:
codice:
/**Classe BookReader per lettura dei libri
* Implementa metodi astratti dichiarati in
* Classe lettura_Panel
*/

}

} catch (IOException e) {

e.printStackTrace();
}
List<PDPage> allPages = inputPDF.getDocumentCatalog().getAllPages();
PDPage testPage = (PDPage)allPages.get(0);
JFrame testFrame = new JFrame();
PDFPagePanel pdfPanel;
try {
pdfPanel = new PDFPagePanel();
pdfPanel.setPage(testPage);
testFrame.add(pdfPanel);
testFrame.setBounds(40, 40, pdfPanel.getWidth(), pdfPanel.getHeight());
testFrame.setVisible(true);

}
Questa è la classe che chiama quei metodi Reader:
codice:
/**Classe astratta lettura_Panel per la lettura dei libri presenti in biblioteca
* Libri in formato pdf e html saranno visualizzati tramite
* Visualizzatori che usufruiscono di librerie esterne,
* Mentre libri in formato epub, saranno visualizzati tramite
* Programmi presente nel pc
