Preferences not being set on windows 7

[Adam Cripps]

I have a simple application that I wrote to help me write reports. Recently at work I have been given a windows 7 machine. My application ran fine under windows xp but under windows 7 it fails to set preferences when the application closes.

I'm using these snippets of code to read and write preferences:

public Preferences prefs; 

then later on...

prefs = java.util.prefs.Preferences.userNodeForPackage (this.getClass());

to check if it has already been set and then take the necessary action if it is (read in and write).

The on exit, I write with this:

String key = subjectTitles[i];
String subject = subjectList[i];
prefs.put(key,subject);

When I run the application, there is nothing on the command line that reports that there is a problem writing the preferences file (I was thinking there might be a permissions problem). Is this a known thing with Windows 7? What else can I do to debug the application? As I said earlier, my code is fine on linux/windows xp machines - it just seems to be this windows 7 setup.

TIA
Adam

I too use Windows 7. Can you show me the whole code? I would like to debug and see what does it do.

Moving discssion as too difficult for “beginning”.

PM coming your way. Although I thought I would debug it, but nothing really shows up on the console about any errors setting preferences.

No need fro a PM Adam. You can share anything here as long as it is legal.
