this is a nice catch. I never noticed that the grid reader would fail
when there are spaces in the path. I already reported the problem to
the grid reader maintainers.

Ok, I made some tests:
1) placing the grid file in a folder with spaces: udig doesn't load it
but the spatial toolbox can use it and behaves properly. Sure,
everything happens "blind".
2) placing the oms libraries (jgrasstools) in a folder that contains
spaces. Everything behaves properly and here I have a problem to
reproduce your issue.
In the toolbox you have the possibility to enable a debugging mode. If
you do so, a lot of info will be added to the run (could you please
run that and let us see the log?). In the first part the actual
command that is issues is shown, in my case something like:
------------------
java
-Xmx64m
-Doms.sim.resources="/home/moovida/TMP/Documents and
Settings/jgt-jgrassgears-0.7.3-SNAPSHOT.jar:/home/moovida/TMP/Documents
and Settings/jgt-hortonmachine-0.7.3-SNAPSHOT.jar"
-cp
.:/home/moovida/SOFTWARE/ECLIPSE/eclipse_3.7/plugins/org.eclipse.equinox.launcher_1.2.0.v20110502.jar:/home/moovida/development/moovidas-udig-git/plugins/eu.udig.omsbox:/home/moovida/development/moovidas-udig-git/plugins/eu.udig.omsbox/bin:/home/moovida/development/moovidas-udig-git/plugins/net.refractions.udig.libs/lib/*:/home/moovida/TMP/Documents
and Settings/jgt-jgrassgears-0.7.3-SNAPSHOT.jar:/home/moovida/TMP/Documents
and Settings/jgt-hortonmachine-0.7.3-SNAPSHOT.jar
oms3.CLI
-r
/tmp/omsbox_script_1609043994395242118.oms
-----------------------
As you can see the oms.sim.resources part has quotes and that is ok.
But the -cp part doesn't and also contains spaces in the path. Since
anyways the path is passed to the java part as a command argument,
this should not be a problem at all, the executor takes every argument
as a block and therefore virtually as "quoted".
I am therefor assuming that there might be some different problem,
which I would like to understand and solve.
Could you please provide the debug log in order to get more insight?
Thanks,
Best regards,
Andrea
