Sorry; you did give us the URL for the project, but since it included "/wiki/"
in its path, my prejudiced mind assumed it was just a page for the discussion
of EIS development. Since I erased your project registration, you will have to
register it again in Savannah (and the new registration will most probably be
evaluated by someone different from me).

Java 2 Enterprise Edition is definitely non-free software.

There is no doubt that your project is free software. What we're trying to
decide is whether we can host it in Savannah or not (if it really depends on
Java 2 Enterprise Edition, we can't)

Then your project does not use J2EE. There are free implementations of Java;
if your project works with those, there is no problem.

OK, no problem.

No problem either.

No problem. The FSF does not recommend using the Apache license in the
development of your own software, but they don't see anything wrong in using
software with the Apache license (such as the Apache http server, for

It is always good to let users choose the XSLT processor they prefer (Xalan,
xsltproc, Sablotron, etc); If you follow the XSLT standard your software
should not depend on Xalan. But even if it does, I don't see anything wrong.
You do not have to feel obliged to use a GPL'ed XSLT processor.

Very unfortunately, SVG has become a non-free specification, with patent
problems; please avoid it. There are some FOP processors. In any case, I'm not
familiar enough with Batik to say if it really depends on SVG and I don't know
if you are really generating SVG graphics files or not.

You do not have to use only GPL software; the important thing is not creating
any conflicts with the GPL which you use for your own code. Please take a
look at http://www.gnu.org/licenses/gpl_faq.html

Very good way of thinking I wish my colleagues who developed the
Information System for our University would have thought like you. We are
certainly willing to help you achieve your goals.
