java.awt.Desktop.open doesn’t work with PDF files?
- by Jason S
It looks like I cannot use Desktop.open() on PDF files regardless of location. Here's a small test program:
package com.example.bugs;
import java.awt.Desktop;
import java.io.File;
import java.io.IOException;
public class DesktopOpenBug {
static public void main(String[] args)
{
try {
Desktop desktop = null;
// Before more Desktop API is used, first check
// whether the API is supported by this particular
// virtual machine (VM) on this particular host.
if (Desktop.isDesktopSupported()) {
desktop = Desktop.getDesktop();
for (String path : args)
{
File file = new File(path);
System.out.println("Opening "+file);
desktop.open(file);
}
}
} catch (IOException e) {
e.printStackTrace();
}
}
}
If I run DesktopOpenBug with arguments c:\tmp\zz1.txt c:\tmp\zz.xml c:\tmp\ss.pdf (3 files I happen to have lying around) I get this result: (the .txt and .xml files open up fine)
Opening c:\tmp\zz1.txt
Opening c:\tmp\zz.xml
Opening c:\tmp\ss.pdf
java.io.IOException: Failed to open file:/c:/tmp/ss.pdf. Error message:
The parameter is incorrect.

What the heck is going on? I'm running WinXP, I can type "c:\tmp\ss.pdf" at the command prompt and it opens up just fine.
edit: if this is an example of Sun Java bug #6764271 please help by voting for it. What a pain. :(
