如何在Netbeans中打开PDF文件？

Question

I want my application to open a pdf file when I click a dedicated button. How would i approach this? Also if I run the application from netbeans it shows the pdf but when compiled nothing comes up?

My code

    private void showHelpMenuItemActionPerformed(java.awt.event.ActionEvent evt) {                                                 
        File f = new File("ana.pdf");
    try {
      Desktop.getDesktop().open(f);
  } catch (Exception ex) {
    System.out.println(ex);}

Answer 1

Your code gets the file from the current directory. The file is there when you run it from netbeans, but the file is not there when you run it.

Unfortunately, there's no easy way to do this. I think the best idea would be write the documentation as HTML, put it on a server, and open the web browser (using Desktop.browse ). If someone else has a better idea, please comment.

You can explicitly give the entire file path, which might solve your problem. Also the OS you are using must support the operation. This might help:

if (Desktop.isDesktopSupported()) {
                    try {
                        File myFile = new File("C:\\Users\\klinks\\Documents\\pdf.pdf");
                        Desktop.getDesktop().open(myFile);
                    } catch (IOException e) {
                        // System probably doesn't have a default PDF program
                    }
                }
