Java 6 has a java.awt.Desktop class, which allows access to the underlying OS to open files. See http://java.sun.com/javase/6/docs/api/java/awt/Desktop.html - I'd be inclined to replace the .dll file etc with this in 3.1.

Comment by Craig Macdonald [ 14/Mar/10 ]

After some searching, I found this solution. It has methods for mac/unix/windows. It uses java.awt.Desktop when it can (indeed using reflection, so java6 is not required), but falls back to other methods. On windows, rundll32.exe is used to prevent the need for native code. We need to test on 64bit windows. Is there a rundll64 equivalent? Should we prefer this on 64bit windows, in case rundll32 dissapears in the future.

Here is an initial patch. I have tested this on Mac. Needs testing on Windows.

Above was probably viz TR-116. Richard has been retesting.

Patch has been tested on both 32 and 64bit windows 7 machines. Desktop search can now correctly open files without error.
