Use the isDesktopSupported() method to determine whether the Desktop API is available on your operation system.

File pdfFile = new File("resources\\ManoeuvreRules-2010.pdf");   
if(isDesktopSupported()){
    try {
        Desktop.getDesktop().open(pdfFile);
    } catch (IOException ex) {
        Logger.getLogger(getClass().getName()).log(Level.SEVERE, null, ex);
        JOptionPane.showMessageDialog( null
                                     , "An error happened trying to open file : " + pdfFile.getPath()
                                     , "IOException"
                                     , JOptionPane.WARNING_MESSAGE
        );
    }
}
else{
    JOptionPane.showMessageDialog( null
                                     , "This is not supported on your Operating System: " 
                                     , "IOException"
                                     , JOptionPane.WARNING_MESSAGE
        );
}

At this line:

btnEdi.addActionListener(new ActionListener() {
    @Override // don0t forget @Override annotation
    public void actionPerformed(ActionEvent ae) {
        desktop.open(txtText.getText()); // here
    }
});

According to Desktop#open(File file) method documentation it takes a File object as argument, not a String, so I doubt your code even compiles. It also throws an IOException that has to be treated.

That being said, this is what I'd do:

btnEdi.addActionListener(new ActionListener() {
    @Override
    public void actionPerformed(ActionEvent ae) {
        File pdfFile = new File(txtText.getText());                
        try {
            Desktop.getDesktop().open(pdfFile));
        } catch (IOException ex) {
            Logger.getLogger(getClass().getName()).log(Level.SEVERE, null, ex);
            JOptionPane.showMessageDialog( null
                                         , "An error happened trying to open file : " + pdfFile.getPath()
                                         , "IOException"
                                         , JOptionPane.WARNING_MESSAGE
            );
        }
    }
});
