How to Check A PDF reader Is Installed With Java

Question

I Tried to open a pdf file using a statement

Runtime.getRuntime().exec("rundll32 url.dll,FileProtocolHandler " + "Sample.pdf");.

But I have not installed a pdf reader in my system. So it when I execute this program nothing is showing. No Exceptions are comming . Any idea getting the exception if the Pdf reader is not installed in the system. If the Pdf reader is already installed this program is working perfect.

EDIT
As my previous solution was not working . Here is another one that would sure work for you:

try
{
  File file = new File("Sample.pdf");
  java.awt.Desktop.getDeskTop().open(file);
  System.out.println("File opened successfully");
}catch(Exception ex)
{
  System.out.println("Error occurred: "+ex);
}

Hi Vishal its not working. It comes inside the if block itself – alenlee Mar 26 '13 at 07:23

For that you have to deal with the register key.

Use JNI to do the trick.

String productName = Advapi32Util.registryGetStringValue(
            WinReg.HKEY_LOCAL_MACHINE, "SOFTWARE\\Microsoft\\Windows NT\\CurrentVersion", "ProductName");
        System.out.printf("Product Name: %s\n", productName);

read/write to Windows Registry using Java
