Re: ARP exception when import model

I don't think anybody ever reported that kind of problem.

I just tried again with the official IsaViz 2.0 ZIP file, as well as 
with my local development version which uses Jena 2.1. I did not 
encounter any problem.

 From the traceback, your JVM seems to be getting the wrong JAR files 
for some reason. This might be happening because your classpath points 
to a wrong version of Xerces. Did you use IsaViz 1.x before installing 
IsaViz 2.0 ? If so, did you uncompress IsaViz 2 in the same directory as 
IsaViz 1.x ? (this might be the cause)

The only thing I can suggest right now is installing IsaViz 2.0 again 
from the ZIP file in a blank directory and then launching run.bat ; in 
addition, verify that you do not have a CLASSPATH environment variable 
set (although this should not change anything as run.bat specifies its 
own classpath).

If this does not work, download Jena 2.1, copy all Jena JAR files in 
IsaViz's lib/ directory, and use the attached run.bat file.
