Hi,
I have a JSP template with the following :
<c:choose>
<c:when test="${aRow.maxcardi != null}">
something
</c:when>
<c:otherwise>
something else
</c:otherwise>
</c:choose>
the used query is :
SELECT DISTINCT ?prop ?maxcardi
WHERE{
?aClass tops:subClassOf ?ancestor.
?ancestor rdfs:subClassOf ?subRestrict .
?subRestrict a owl:Restriction.
?subRestrict owl:onProperty ?prop .
LET (?maxcardi := smf:maxCardinality(?aClass, ?prop)) .
} ORDER BY ?label
It work fine.
If I change the JSP to :
<c:choose>
<c:when test="${aRow.maxcardi != null and aRow.maxcardi ==
'1^^xsd:integer'}">
something
</c:when>
<c:otherwise>
something else
</c:otherwise>
</c:choose>
I does not give the correct result. aRow.maxcardi even if equal to 1
does not match the test.
I know the value is one because I have tested it with a sparql query
in TBC.
What is the problem. Also, will I be able to use operators other then
== and != such as > and <.
The management of variable typing in the JSP-SPARQL stuff is very hard
to use....
cheers,
James
