Re: Problem upgrading from 0.94 to 0.95
Also it may be helpful if you are able to tell us which version of JEuclid you are using.

Re: Problem upgrading from 0.94 to 0.95
Posted by Nobble <pa...@gmail.com>.
Well, I removed the jeuclid libraries and apache fop compiled the document
but threw up some errors. One of those errors concerned an incorrectly
specified path to a system directory containing images. The drive
specification was missing from an uri of the form file:///... I added the
drive specification (file:///C:/...) and this error was fixed. There were
lots of font warnings and most of the symbols in the document are currently
represented by a hash, but I have ignored that for the moment as a separate
issue to fix.
I then put the jeuclid libraries back... and low and behold, I am no longer
able to reproduce the crash I was having before. I have also tried a
document containing mathml, and even though there are other problems with
it, the mathml is rendering just file.
So, it appears to have been a false alarm, or, at least, apache fop wasn't
correctly catching some file specification error and providing a sensible
error message.
Cheers, Paul

Paul,
due to changes in the ImageLoader API you have to use matching version
of JEuclid for FOP to work.
I tried to reproduce your error and I was unable to reproduce it using
FOP trunk and JEuclid 3.1.3.
Also, in the .fo given:
http://www.nabble.com/file/p20339979/doc.xml.fo
There is no MathML used.
If this is the file you're having trouble with:
- delete (temporary) the jeuclid libs and see if that helps. If so, I
need to fix this in JEuclid [ I'll then ask for more information ].
- if that did not change anything it's a bug in fop. In this case,
please make the PNG files available, maybe there error lies therein?

I have now tried with the combination: apache fop 0.95 and jEuclid 3.0.3. I
get this error:

I upgraded jEuclid at the same time as I upgraded fop. I was using jEuclid
3.0.3 with fop 0.94... but am using jEuclid 3.1.3 with fop 0.95.
