I've removed the line url.openConnection(); and added an if() block: if(url != null) { img = Toolkit.getDefaultToolkit().getImage(url); } In this case it does seem to work just as well. I wasn't sure if it would because this wouldn't cater for the case where the URL was non-null but...

No, but that should be caught by the "try ... catch(Exception ex)" block, shouldn't it? The only thing I can think of is that Toolkit.getDefaultToolkit().getImage(url) is firing off the ImageFetcher listed in the stack trace in another thread which isn't handling the exception. I suppose I could...

I am trying to write an application to be launched via our intranet site using Java Web Start, and I want to store resources such as images in a separate jar file so that they can then be easily re-used in other similar apps. The resource jar file is also stored on a central server and can be...

Just a thought: Couldn't you create an array of TimeSeries objects before iterating through the data? That way you could use the standard ResultSet functionality to step through the data a row at a time building up your TimeSeries simultaneously, and add them all to the TimeSeriesCollection at...

No, I've double-checked this and the local administrator account is the only one that's listed in the permissions for the shares I'm using. A "Domain Administrators" group does exist, as does an "Administrators" group on the local machine, but neither are listed in the share permissions.

Hi Yes, you're right - I can change the passwords and probably will. That would be the better solution and is probably as easy from an admin point of view, but I was hoping (naively?) that there might be a simple way to set up the shares the way I want and also to satisfy my curiosity! One...

Does anyone know if it's possible to set or override the permissions on the default shares C$, D$ etc. which Windows XP automatically creates for each hard drive/partition? I have a security problem with them because some users on our network know the password for the local administrator...

Looks like it's still overwriting rather than inserting text in the file. I think Custom24 is right about your solution 1 being the only one which will work. A RandomAccessFile will allow you to write at any point in the file, but it will overwrite whatever's already there; the file won't grow...

Looks like the value you're taking from the input field (which is a string) has a '$' character at the beginning. You'll need to do some additional formatting to remove this before passing the string into the Double constructor. I think the comma might also cause problems, so you might need to...

Does anyone know if there's a way to detect either: the size and position of the task bar or the dimensions of the desktop minus the task bar in Java on Windows NT/2000/XP? Using java.awt.Toolkit.getDefaultToolkit().getScreenSize() I can get the screen dimensions, but this doesn't take the task...
