I'm very impressed by this extension. Admittedly not something that I use on daily base but this was something I needed some months back and I guess in future I'll again. A colleague of mine was asking for such a feature in OOo too. Glad to see it now being available. Moreover I'm impressed by the extension technology. There seem to be endless ways to enhance OOo. Great.
Will this extension become a "core" component of OOo in future when it's mature? As far as I know is this the case for Languagetool.

Regards
James

BTW, with more and more extensions dropping in each day I which somebody would create an extensions which just needs a few clicks to install the most downloaded or newest or all those for OOo/Calc and so on.

To Andreas Scheider,

Hi,

I tried to reproduce the NLP Calc extension example posted on : http://blogs.sun.com/GullFOSS/entry/solver_for_nonlinear_programming.

Unfortunately the OOo NLP Calc extention crashed OOo and generated the bugreport appended below..
I presume the problem is related to the fact I use the 64-Bit version of OOo 3.01
Please advise on how to resolve the issue.

Thanks, Kind regards,
Marc

I'm not Andreas, but I recommend to use a build from download.openoffice.org to see if the crash goes away.

Posted by Mathias Bauer on March 30, 2009 at 06:56 PM CEST #

This sounds really stellar, Openoffice 2.6 built for Ubuntu had a non-linear solver, but 3.0 does not and I need it for my work.

Unfortunately, trying to install this gives me the following error, which I have no idea how to interpret:

(com.sun.star.registry.CannotRegisterImplementationException) { { Message = "", Context = (com.sun.star.uno.XInterface) @0 } }

Is there something I can do to make this work with my installation? I am using the standard build that comes with Ubuntu 9.04 (32 bit) and tried it with both Sun Java 6 and Sun Java 5 JREs.

Posted by Brian Neltner on April 01, 2009 at 12:11 AM CEST #

As I wrote in my last comment: please use a build from download.openoffice.org.

Ubuntu might ship the go-oo-o build that might not be compatible with some extensions. As we can't test extensions with builds that other people do we can only help if you are using a "vanilla" build.

BTW: what is OpenOffice.org 2.6?

Posted by Mathias Bauer on April 01, 2009 at 12:17 AM CEST #

Thanks Mathias, I tried that and it works now! The new solver is great, much better than the one in the 2.4 version of OpenOffice. With the old solver, I frequently had to tell it to solve hundreds of times before it converged; I love the new interface, and am much more confident in the results using the new methods.

Posted by Brian Neltner on April 01, 2009 at 04:44 PM CEST #

Ah, the 2.4 version from Ubuntu...

Yes, it contained another solver component provided by a Novell developer.

I'm glad you like the new solver. :-)
