a NumberFormatException

[Aliza Lila]

Hi,

Using some vary basic rdf, partly copied from the W3school website, i keep  
getting the same console errors. I installed all the latest dependend  
packages, and configured IsaViz correctly. At least that is what i think i  
did ;-)

One tip, for other users, i solved one problem with a dependency: it  
involves a jena error: some ../irifactory not found error when i loaded  
the rdf file (see below). I solved that by modding the classpath in the  
run.bat by adding something like lib/iri.jar

---- the software ---
winxp
IsaViz 3.0 alpha
jena 2.4 libs copied
latest zvtm, graphviz, java etc.
---- end of software list ---


----- sample rdf file ------
<?xml version="1.0"?>

configured properly), your default namespace and anonymous node prefix  
declarations

Yes, that's a JAR file used by Jena since v2.4 ; it is not required when
using Jena 2.3.

Where did you get it from exactly ? CVS? or one of the builds on lri.fr ?

This file works fine on my local copy. Actually, the layout is kind of
messed up (don't know why), but I don't get any parsing error.

What version of GraphViz are you using ?

I've just put a new release (2006-12-05) on that page. Give it a try.

You should stick to antlr 2.7.5. everything was compiled with that
version and using a more recent one might cause problems.

That probably wouldn't solve your problem. As I'm mostly using a Mac, I
can't tell you if graphviz 2.11 is the source of the problem (not easily
available on Mac). But it might be. Try using an earlier version maybe.
I'll be able to tell you for sure by Thursday.

Good.

Are you talking about the Sesame plugin for IsaViz? If so, I'm not sure
it is still working with IsaViz 3.0-alpha. But the error you are
mentioning does not sound like an IsaViz-related issue. When does it happen?
