License question

[Stefan Hagström]

Hi, excuse my rather lame question, but i have som difficulties interpreting the LGPL-license. I´m currenty studying at BIT (Blekinge Institute of Technology). Here at BTH each student gets a "individual project", that has a "real world"-approach, ie we have customers (older students). My projects is to develop an application for simulation of technical analysis.
One of my customers requirements is to be able to resell the application, of course without violating any licenses

What i wonder is if it´s possible to use JFreeChart and resell the application.

As i have interpreted the LGPL, if i dont make any changes to the JFreeChart source code it self, but just use the .jar files of JFreeChart and JFreeCommon and distribute them separatly i will not violate the LGPL, is this correct?

If not, is there anyway to do this? A wrapper library releases under LGPL for example?

Hi Stefan,

When you distribute your application that uses JFreeChart, you need to include:

(1) the source code for JFreeChart, including any changes you have made to it (if you made any);

(2) a copy of the GNU Lesser General Public Licence, so that your users know that (a) JFreeChart is free software; (b) there is no warranty for JFreeChart;

And that is about all you need to do...you don't need to distribute the source code for your application, if you don't want to.

Regards,

DG.
