Re: [Tn5250j-general] TN5250J for commercial use?

I am by no means an Open Source license expert, but as I understand the GPL, you can include tn5250j in a commercial application, as long as you include all the source code, a copy of the GPL and don't charge for more than the cost of distribution. If you make general enhancements to the code, you must include the source for those enhancements as well and distribute them under the same licensing arrangements. Note that Linux is distributed under the GPL so you can see that "commercial" GPL licensed code distribution is common.

If you already have a commercial app, and want to add tn5250j, probably the most simple way to do it is a a free download or a separate CD and license so you maintain the distinction between what you license for a fee and what you have as free. Should you add proprietary extensions, not based on existing source, you can charge for those features and license them however you want. However the base tn5250j must remain free and licensed under the GPL.

There are folks who know a whole lot more about this than I do. I don't know if there are commercial licensee's on this list or not. We are a commercial software developer, but we charge only for support, we give all of our software away for free (under various licenses, including the GPL).

You can always Google for more on the GPL.   There is a lot out there.

Hope this is helpful.

I can see that the license is GPL.

I have mailed Kenneth and also asked this question in the Support Requests
forum whitout any response.

Have any of you used it a commercial application and what are the license
terms?
