About the Sun's JAVA JRE redistribution on Knosciences
I think we can redistribute the Sun's JAVA JRE on our CDs.
Here is an extract from Sun's JRE 1.4.x license and some comments from the debian java faq. Following are my own comments on the JRE distribution on an Educational CD like KnoSciences.

Section : SUPPLEMENTAL LICENSE TERMS
License to Distribute Software.
Subject to the terms and conditions of this Agreement, including, but not limited to the Java Technology Restrictions of these Supplemental Terms, Sun grants you a non-exclusive, non-transferable, limited license without fees to reproduce and distribute the Software, provided that
(i) we distribute the Software complete and unmodified (unless otherwise specified in you distribute the Software complete and unmodified (unless otherwise specified in the applicable README file) and only bundled as part of, and for the sole purpose of running, your Programs, the applicable README file) and only bundled as part of, and for the sole purpose of running, your Programs,
(ii) the Programs add significant and primary functionality to the Software,
(iii) you do not distribute additional software intended to replace any component(s) of the Software (unless otherwise specified in the applicable README file),
(iv) you do not remove or alter any proprietary legends or notices contained in the Software,

Read on the Java Debian FAQ : http://www.debian.org/doc/manuals/debian-java-faq/ch5.html
5.3.3.1 Can Debian distribute JRE?
(Quoted from Gene McCulley http://lists.debian.org/debian-java/1999/debian-java-199908/msg00021.html) I don't think we can or want to distribute the JRE with Debian. The supplemental license terms of the JRE has a few very nasty clauses:
1. License to Distribute. You are granted a royalty-free right to
reproduce and distribute the Software provided that you: (i)distribute
the Software complete and unmodified, only as part of, and for the sole
purpose of running, your Java applet or application ("Program") into
which the Software is incorporated;
We might get away with this one since we distribute it together with Java applications bundled with Debian. But we also do want to allow people to download only the jre package.
(ii) do not distribute additional software intended to replace any component(s) of the Software;
But we cannot agree to this one. We want to distribute Kaffe, Japhar, Classpath, Gcj, Kopi, Fastjar, etc which are intended to replace the JRE with a Free version. Even if we don't consider non-free part of Debian (the JRE would not go into main :) I think we should not encourage software that tries to prevent Free replacements.
[?] (v) may not create, or authorize your licensees to create additional classes, interfaces, or subpackages that are contained in the "java" or "sun" packages or similar as specified by Sun in any class file naming convention;
My example why this is a bad clause was not so good since someone pointed out that you do not want to create something that is non standard. I do agree that we want a standard implementation of the core classes, but I also think that you should have the freedom to create non-standard classes. (Or fix bugs or stupid mistakes in the standard classes.)
[?] and(vii) agree to indemnify, hold harmless, and defend Sun and its licensors from and against any claims or lawsuits, including attorneys' fees, that arise or result from the use or distribution of the Program.
And I don't think that Debian (or SPI) can or wants to do that.
So I am afraid that we also cannot distribute the Sun or Blackdown JRE. This isn't that bad since it is non-free software, but it is annoying. As I said before please help one of the (many) Free Java projects out there if you want to see a Free JVM, Standard Classes, Compiler, etc. in Debian. They are far from complete but they do work for most purposes.
Knosciences comments following the Sun's license :
(i) we distribute the Software complete and unmodified and only bundled as part of, and for the sole purpose of running, JAVA Programs,
(ii) the Programs add significant and primary functionality to the Software,
(iii) we do not distribute additional software intended to replace any component(s) of the Software (We removed Kaffe, Japhar, Classpath, Gcj, Kopi, Fastjar, etc.. from Knosciences)
(iv) we do not remove or alter any proprietary legends or notices contained in the Software,
(v) we only distribute the Software subject to a license agreement that protects Sun's interests consistent with the terms contained in this Agreement, and
(vi) BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
Conclusion
Debian do not want to distribute the JAVE JRE from Sun because they want to distribute Kaffe, Japhar, Classpath, Gcj, Kopi, Fastjar, etc … which are intended to replace the JRE with a Free version.
But we can distribute the Sun JRE if we do not distribute free remplacements for the JRE. In Education, we need to do this because a lot of great GPL'ed software can be used.
As Knosciences do not distribute free remplacements for the JRE, we redistribute the SUN's JRE on our CDs.
