Rafael, why BSD, not GPL?

Because GPL completely sucks ;)

Many people don't use your software when it is GPL.
Moreover, I don't like Richard Stallmann at all.

Why not dual license then?

Using GPL? not at all.

Why GPL? Using a non-gpl license, you can use the software wherever you want. Using GPL, you "contaminate" your software.

To make sure it'll always be GPL

Except mixing it with GPL code, I think (wrong?)

Well, that's not an option, anyway. I make a rendering view for JSP but don't make JForum GPL

When I released my first open source project, http://libcgi.sourceforge.net, many people said ".. your project is cool, but I can't use it on my company because it is GPL... ". So I changed the license.

I want people to use my software, make money from it or anything else. People use GPL when they want to protected himselfs againts bad use of his software. I mean, they use gpl when they want to make sure that other people will not embed the soft in something comercial and sell it without gaving the contribution back to the author, or worst, opening the entire source code.

Of course this doesn't prevent that someone do it anyway...

But, if we think in this approach, I guess that a much better license is one that says ".. and you can use this software for non-comercial purposes.. If you want to use it to make money or anything else non-academic, you should pay.. ".

Didn't understand that one. What JSP?

The question is: can I use JForum in GPL software? If not - well, no big deal, I'm not losing my interest in it just because it's not GPL

yessss, sure you can. This is the nice thing about non-gpl licenses: you can use a software that is not gpl in your gpl software. The inverse is a much more complicated.

So effectively JForum is already dual-license? I mean I could just get it and change one line and rerelease it under GPL? But wait, I can't do that since I'm obliged to include "the above copyright notice, this list of conditions and the following disclaimer." (from your source files). The nice thing about GPL is that (providing that licensee's not criminal like KISS technology or someone else ) instead of providing author with a banner of fame, it provides the world with more free software since modifications are always GPL That's the way I see it.

No, it is not dual. It only means that you can include my bsd code in your gpl code without any "'legal" problem.

And only that. BSD says that you can do anything with the code, as long you give credits to the original author. Is very reasonable.

Aka, viral license. If I have a comercial system and want to use your GPL code, I have a problem, since GPL says that I must release it under GPL as well. Commercially it much harder to fit GPL.

In the site, there is a indication that jforum is in BSD License.
But in the source codes not.
Why? In the source codes, there isn't any indication that the license is BSD.

It does not mention "THIS IS A BSD LICENSE", but it's the one itself . The important thing is that the rules of use are there. The name of the license, in my opinion, is not relevant.

Ohhh,
sorry by the question.
I found the bsd lincense.
This text in your source files is the BSD license.

http://www.opensource.org/licenses/bsd-license.php


What I should do when I change your source files?
How can I show the diferences of your code and the changes that i realized?
[originally posted on jforum.net by Anonymous]

It sure does. Every single .java file has the BSD license.

Related to what? If you want to make chages specific to your environment, you're free to do. If you want to contribute code to JForum..well, just send the diff

You can use a diff tool, like WinMerge and "diff", in unix like machines.

I once asked the Gaim guys why they didn't use openssl, and they told me they couldn't since gaim is gpl and openssl is bsd.

So i really don't know what license should i use, since i don't know if it's legal for bsd products to use gpl products (what happens if a propietary company wants to use a bsd product that uses gpl products), neither i know if it's legal to use bsd code in gpl (due to the advertising clause in bsd and other incompatibilities.

Supose that I want to create another forum tool based on JForum. I will change some classes. What I should do in this classes, relative to the license text, to indicate my changes?
I need to indicate the changes in each file? Or I need to create a readme file and put the changes in this file?
I alread read the BSD License, but this cases aren't mencioned.

That's not true. GPL programs can use BSD stuff. The opposite is not valid, though.

You don't need to indicate your changes, just put something like "this program uses code from the JForum Project", and a link to the project's website. You may want also to put a copy of the BSD license into a separated text file.

Do I need a commercial license of MySQL to use with JForum?

This is the text I found on the MySQL site:
"If you include the MySQL server with an application that is not licensed under the GPL or GPL-compatible license, you need a commercial license for the MySQL server."

[originally posted on jforum.net by Didas]

[Migrated From Jforum.net]

JForum does not include MySQL server, so you won't have any problems.

Rafael
[originally posted on jforum.net by Rafael Steil]

Does this have any relevance?
"If you include one or more of the MySQL drivers in your non-GPL application (so that your application can run with MySQL), you need a commercial license for the driver(s) in question. The MySQL drivers currently include an ODBC driver, a JDBC driver and the C language library."

Sorry, just want to make sure everything is legit and we are not violating any policies.
[originally posted on jforum.net by Didas]

[Migrated From Jforum.net]

Yes, this is valid for the driver. But, in fact, who cares? The license says that if I include the driver, I should buy a comercial one. I see this way: JForum is open source, and of course I'll not buy a connector/j's license.
However, if you're afraid, you always can buy a license. I put it in the package for convenience.

The original BSD license isn't GPL-compatible license.
But JForum is under a modified BSD license which is a GPL-compatible license. That means if you use JForum, you don't need to buy the commerical license for MySQL.

Moreover, hosting companies normally provides MySQL database for shared hosting with the commerical license paid for.

JForum also works with PostgreSQL.

JForum is under a GPL-compatible license, hence the above statement doesn't apply.

Thank you for a true open source software!!!
I can't say the same thing about another competing java-based forum that on the website claims to be free and licensed under GPL, period. But when you download the source code you find a little txt file that adds some "minor" restrictions...
