Using iText to open PDF documents after writing to them

Question

Im using iText and the Document class in a JFrame to write PDFs but if i try to use the Runtime class to run it after creation i get an exception that i cant open it due to the locks still on it and if i run Unlocker on it, my JFrame has a lock token on it. How do i open the PDF if i want to write to it?

Document d = new Document();
.... code
d.close();
Runtime.getRuntime().exec("D:/PDFChartStuff.pdf");

If you are using windows you can use rundll32 to launch a pdf file.

Try something like this

String pdfFile="D:/PDFChartStuff.pdf";
if (pdfFile.toString().endsWith(".pdf")) {
                Runtime.getRuntime().exec("rundll32 url.dll,FileProtocolHandler " + pdfFile);
            } else {
               //For cross platform use
                Desktop desktop = Desktop.getDesktop();
                desktop.open(pdfFile);
            }
