JTextPane and his ancestors JEditorPane and JTextComponent won't respect the color defined with setBackground(Color) since they display a "styled document" and expect the background color to be defined in the content. You'll always see a white background.
To change the background color (without modifying the content) you have to define attributes for the document:
When doing MVC programming in Java, there is a problem that most people don't know about. I've ignored it myself much too long. The problem is that when you bind a model class to an UI component you will get a giant memory leak.
What happens?
Well, imagine a model class supporting listening for property changes. A simple example might look like this (I extend from PropertyChangeSupport here so that I don't have to delegate all the methods, normally you wouldn't do so, of course):
In my current Abobe Flex project, I needed to upload multple generated files and form fields to a server. UploadPostHelper by Jonathan Marston is a great for uploading one file at time, but sadly I couldn't use (or even modify) it - it's licensed under NonCommercial CC, and my project is a commercial one.
So I had to write my own code which I would like to share with other's (dual-licensed under MPL 1.1 and LGPL 2.1).
Symfony provides a nice feature called "embedded Forms" (sfForm::embedForm) to embed subforms into a parent form. This can be used to edit multiple records at the same time. So let's say you have a basic user table called 'sf_guard_user' and a profile table called 'user_profile', then you might follow this guide to merge these forms together:

For further development and improvements, contact me or have a look at this public github repository created by Adam Nelson.

If you need flash support, you should have a look at the current github version of this script at http://github.com/AdamN/python-webkit2png/ mentioned above. We've extend the script a few month ago.
From time to time you may want to create a screenshot of a web page from command line, for example if you wish to create thumbnails for your web-application. So you might search for such a program and find tools like webkit2png, which is for Mac OS X only, or khtml2png, which requires a lot of KDE stuff to be installed on your server.
But since Qt Software, formerly known als Trolltech, integrated Safari's famous rendering engine WebKit (which is based on Konqueror's khtml engine) into its framework, we are now able to make use of it with the help of some Python and PyQt4.
If you are in a hurry, click here to get a full-featured version of webkit2png.py.
If you're running a Drupal-based webpage which is completely restricted to authenticated users, Anonymous would get an "403 Access Denied" on every page he tries. But if you want your visitors to see a friendly login page (instead of just this error message and a small "login block") you might want to put the following code into your sites/default/setting.php:
