opening PDF file under XP works but not under Vista

[Peter Rait]

Hi,

I try to open a self generated PDF file (using iText) with:

public static void OpenPDF(String PDFName) throws Exception {
Process p =
Runtime.getRuntime()
.exec("rundll32 url.dll,FileProtocolHandler "+PDFName);
p.waitFor();
}

This works very well under WindowsXP but not under Windows Vista. Did
anyone have already the same experience (probably with another file
type) and find another solution?

Thanks
Peter

Java 6?

.exec("rundll32 url.dll,FileProtocolHandler "+PDFName);

two things to try

1. just pass the name of the PDF file to exec. Make sure you have an
association set up to a reader. See
http://mindprod.com/jgloss/association.html

2. pass the name of the PDF file as a parm to a command processor
which you exec.

3 that approach you are using wants an URL , not a filename
eg. file://localhost/E:/mindprod/thing.pdf


See http://mindprod.com/jgloss/exec.html
for details.

.exec("rundll32 url.dll,FileProtocolHandler "+PDFName);

Hello Roedy,

two things to try

1. just pass the name of the PDF file to exec. Make sure you have an
association set up to a reader. See
http://mindprod.com/jgloss/association.html

I think this is already in place as I have also a link in the program
menu to a static PDF file which opens correctly.

2. pass the name of the PDF file as a parm to a command processor
which you exec.

If you mean:
Runtime.getRuntime().exec("cmd.exe /c myfile.pdf");

3 that approach you are using wants an URL , not a filename
eg. file://localhost/E:/mindprod/thing.pdf

I changed my command to:
Runtime.getRuntime().exec("rundll32 url.dll,FileProtocolHandler
File://"+myPDFPath);
which works in my environment (XP).

I will try the two options.

Thank you for your help
Peter

Thanks, but I do not want to require Java 6 installed on the PCs of the
users getting my application. I will give the suggestions of Roedy Green
a try.

Why not, now that Java 5 has entered its "End-of-Life" transition? By
what reasoning do you insist that your customers use obsolescent software?

Probably you are right, but as I do not know which OSs the users are
running (NT4, w2000, XP, Vista..) I want to try the lowest level. They
cannot even tell me which operating system they have as they have
nothing to do with IT. They are just dieticians, physicians, pharmacists.

Other way around. He's not forbidding Java 1.6, he's just not
requiring it.

My company makes software that runs in containers (appservers and
webservers), and it's just becoming feasible to include features that
require 1.5 (yes, I meant to type 1.5). As an example, IBM builds a
version of WebSphere to use the current JDK, which quite possibly
won't be the newest one when that version of WebSphere is released.
Then vendors target their applications to the current version of
WebSphere. Finally, end-users buy WebSphere, purchase some
applications, and run it until there's a good reason to upgrade. The
result is that many WAS installations in the world are still running
quite happily on JDK 1.4, and so long as they work and they can get
support from IBM and their application vendors, will continue to do
so.

Both approaches worked for Vista, so thank you very much for your hints.
