Runtime.exec() command to open default pdf reader

Question

Hello
I want to launch a pdf-file (from within the code) on the system default pdf-reader. Can I somehow retrieve the path to the default pdf-reader and use it like this:
String pdfReaderPath = retrievePDFreaderpath(); // ????
String filename = new String("E:\\Test.pdf");
String[ ] open = {pdfReaderPath , filename};
try {
Process proc = Runtime.getRuntime().exec(filename);
} catch (IOException e) {
e.printStackTrace();
Thank you!

Following is my simple code.
import java.io.*;
public class PdfExec {
public static void main(String argv[]) {
try {
Process proc = Runtime.getRuntime().exec("//whmax/WHMAX-COMMON/Bass/FRMGEB01.2005 0204 Invoice.pdf");
catch (IOException e) {
e.printStackTrace();
Any help will be appreciated. Thx!
