Hi Kevin,
you only need to switch off inferencing when you register the SPIN
functions. This can happen with a different Jena Model than the rest of
your application. My guess is that even for the execution of the SPIN
mappings you won't need inferencing. You could run them separately and
then add them (as subgraph) to your application model that has Jena
inferencing activated.
Would that work?

Actually, this is still a problem for me. I was mistaken; OWL_MEM
(the one that works) does /no/ inferencing, and my application
actually requires some basic RDFS inferencing, which is why I was
using OWL_LITE_MEM_RDFS_INF.
So... any hints on how to get SPIN to work with OWL_LITE_MEM_RDFS_INF?

Thanks for the reply Holger.
I found the problem. I was using
OntModelSpec.OWL_LITE_MEM_RDFS_INF, b/c up until now I have had
very little inferencing going on, and I was trying to get maximum
performance.
Once I changed it to OWL_MEM it works.

Hi Kevin,
judging from the source code, this function seems to use
sp:arg as one of its arguments, but it should be sp:arg1 etc.
It tries to use the index as an Integer but that fails because
it's then the empty string.
I wonder why this doesn't work, but your suspicion about
missing imports sounds plausible: this particular function
inherits an argument declaration from its superclass
spinmap:TargetFunctions. But this is defined in a different
file and then if you try to just register the function from
the spinmapl file itself it will fail. Please try wrapping
this into a MultiUnion that includes the spinmapl and spinmap
graphs and then register this union graph in the ModuleRegistry.
HTH,

Am I perhaps forgetting to import an ontology or a jar file?
I should mention that I have turned off imports with jena's
OntDocumentManager.setProcessImports(false) because this app
sits behind a firewall and we want to strictly control what
gets imported.
