What's "it" that does not provide stacktrace? Exceptions provide a
stacktrace.

The message comes from Node.getURI() - one of s or p isn't a URI.

Subject: Apache Jena Unsupported Operation Exception
Hello there I get the following exception when I run the code below. I
use the maven dependency for Jena apache-jena-libs:2.10.1 : pom
WARNING: Exception java.lang.UnsupportedOperationException INFO:
ERROR: nodecfcd208495d565ef66e7dff9f98764da is not a URI node:
The following code causes this error.
Statement statement = null;
com.hp.hpl.jena.graph.Node s = Utils.convertToJena(nodes[0]);
com.hp.hpl.jena.graph.Node p = Utils.convertToJena(nodes[1]);
com.hp.hpl.jena.graph.Node o = Utils.convertToJena(nodes[2]);
Resource s1 = model.createResource(s.getURI());
Property p1 = model.createProperty(p.getURI());
if(o.isURI()) {
Resource o1 = model.createResource(o.getURI());
statement = ResourceFactory.createStatement(s1,p1,o1);
}
else if(o.isLiteral()) {
Literal l1 = model.createLiteral(o.getLiteralLexicalForm());
statement = ResourceFactory.createStatement(s1,p1,l1);
}
else if(o.isBlank()) {
Resource o1 = model.createResource(o.getBlankNodeId());
statement = ResourceFactory.createStatement(s1,p1,o1);
}
model.add(statement);
Any help would be appreciated.
Thanks.
