Preferences on the Mac

[Mike Lipay]

I tried creating a preferences file using the code below, it works on Windows but not on Mac. Is there something else I need to do, or a different way to accomplish this?

	// Read the preferences to get the swReg.obj directory
		Preferences root = Preferences.userRoot();
		final Preferences node = root.node("/com/lipay/swreg");
		System.out.println ("\n" + node);

		swRegDir = node.get("swRegDir", "na");

		if (swRegDir.equals("na"))
		{
			swRegDir = "swRegFiles";
			node.put ("swRegDir", swRegDir);
		}

If the user executing the code doesn't have permission to write on the path used (the whole path) - then it is not possible.

OS X is based on Unix (or is Unix), therefore the right owner/group permissions are needed.

I don't think there should be a permissions problem - a user should be able to access anything in her own userRoot, no?

Or do you mean the actual file "/Users/xyz/Library/Preferences/com.lipay.swreg.plist"? That would be screwed-up file permissions, though.

I think it could be necessary to do a "Repair Disk Permissions" with "Disk Utility"??

I have just tested the code posted, and it works on my Mac.

Thanks everyone, I found the problem.

Working between the two platforms I missed changing a \ to a / when I moved it to the Mac. After doing a couple different searches on this forum I finally hit one that covered System.getProperty("file.separator"), our class hasn't covered system properties yet, so I replaced \ everywhere with the file separator constant.
