Hello,
I'm working with the spin java API (1.2.0 version) and found something
I think could be considered as a bug. The following code works fine
with the "OWL_DL_MEM_TRANS_INF" spec for loading the OntModel:
Resource r = ontModel.getResource(sQuery);
Resource body = r.getProperty(SPIN.body).getResource();
org.topbraid.spin.model.Query spinQuery = SPINFactory.asQuery(body);
com.hp.hpl.jena.query.Query arqQuery = ARQFactory.get().createQuery(spinQuery);
But when I use the "OWL_MEM_MICRO_RULE_INF" spec (which is a little
more complete one) the program fails at the third line:
Exception in thread "main" java.lang.NumberFormatException: For input string: ""
at
java.lang.NumberFormatException.forInputString(NumberFormatException.java:48)
at java.lang.Integer.parseInt(Integer.java:470)

org.topbraid.spin.examples.tests.TestQueryRetriever.main(TestQueryRetriever.java:25)
It seems to be a parsing problem, but I'm not really sure. The Sparql
query I'm trying to load is the following:
SELECT ((xsd:float(?nc) * xsd:float(?power)) AS ?ress)
WHERE {
?arg1 myexample:hasNumberCore ?nc .
?arg1 myexample:hasPoer ?power .
}
Has anyone else dealt with this issue or it's just an specific problem
of my model/code? I haven't found any help over the Internet, only a
thread in the group, but it doesn't seem to be the same problem:

Thanks in advance
