 I think that I'm pretty clear on GPL/LGPL; I've been part of these kinds of discussions for a very long time, since the posting of the first GPL. I actually used both commercial Emacs products (CCA and Unipress I think they were called) at work at GE Lighting in 1985; products that caused Richard to write GNU Emacs and the GPL 1.0. I've also imported GPL/LGPL software into several large companies over the years so I jump into this discussion out of long habit. You are right that the one question asked specifically about Java and GPL, which was probably an oversight by the questioner. The last sentence of Eben's answer however makes it clear that LGPL+Java wouldn't be a problem. His answer on LGPL was: "If the author of the other code had chosen to release his JAR under the Lesser GPL, your contribution to the combined work could be released under any license of your choosing." sdw Cutler, Roger (RogerCutler) wrote: >I believe that there is some confusion here between GPL and LGPL.
