Yes, in general this is how it works. But make sure that you actually talk to a lawyer that specializes in software licensing as things could be different in your country.

JFreeChart nor JCommon contain any encrypting codes. Heck, they do not originate from the US either, as except for US people no one cares about that panic making stuff. Of course, the JDK contains encryption libraries and thus your *overall* product may be problematic if you ship a JRE. But as usual...

Ages ago, JFreeReport has been renamed Pentaho Reporting. Yes, it is still there and stronger as before.

The downloads are still the same:

The headless mode works perfectly, if you stick to the sane limitations that come with it. Do not (I repeat: DO NOT) create heavyweight AWT components and you should be totally fine. If your code makes use of a ChartPanel, a ApplicationFrame or other similar classes, you are doing it wrong. Stick wi...

No, there is no GUI component for it. JWorkbook is just a IO-library for reading and writing these documents. If you're not afraid of GPL code, then the SharpTools ( http://www1.cs.columbia.edu/sharptools/ ) might be a option for you. On the close-source side, there are a few components available as...

So why dont you simply enable X11-Fowarding then? See your faviourite sshd.conf man-page for details on that. But be aware that the use of ApplicationFrame classes outside of demo code is rarely correct (unless correctness includes the hard killing of your application via "System.exit(0)" - as this ...

A constructor must be named exactly like the class in which it is defined. Go grab yourself a beginner's Java-Book, it will serve you well.

and please note that we at jfree.org do *not* publish maven artifacts to any public repository. (Reason for that is the insane upload process. I'm not going to waste a single quant of my sanity in that process. I'd rather translate the various IRS forms to mandarin than to enter that road.) We provi...

I'd rather pump up the quality of the JPG encoding (to 0.99 or so) than to go for a 256-color fileformat.

The ChartFactory is a factory, there is no doubt about it. The "holy book" mentions two factories: the "Abstract Factory" pattern, which I actually never used in the real world, and the pattern called "Factory Method". The ChartFactory class is a great example for having many factory methods. The ob...

Also note that a repaint-request is not immediately honored by the AWT. If more than one repaint sits in the queue, then only the last one will be honored. So if your system is under stress or fires redraw events faster than the AWT handles them, you will see some dropped requests and definitely no ...

Browsers are notorious to not being able to handle large files. A 300K entries map will very likely result in a very large DOM tree - and each node there eats memory, thanks to a rather inefficient implementation and the need to make the DOM available for JavaScript. So your death-of-the-browser is ...

JCommon is not on your classpath.

A search for ClassNotFoundException and WebSphere will give you enlightment. Otherwise, if the road to enlightment seems to rocky today or to crowded with prophets and other folk, consult FAQ item 10.
