-- Jena出错问题询问？？？急求解答！
我做了一个简单的本题操作程序，可是执行时的报错令我疑惑，程序在别人那里可以运行，而且所用的包我也导进来了，怎么在我的机器上就是报错啊？？？而且在Dos下执行时也报同样的错误。 请各位大侠帮帮忙吧，谢谢了！我用的是eclipse3.2+jena-2.5+jdk1.5 源代码：-------------------------------------------------------------------------------------------------
import java.io.FileInputStream;
import java.io.FileNotFoundException; import com.hp.hpl.jena.ontology.OntClass;
import com.hp.hpl.jena.ontology.OntModel;
import com.hp.hpl.jena.rdf.model.ModelFactory; public class Testmain {
public Testmain(){
}
public OntModel getModel(){
String file = "D://testOWL/terrorOnt.owl";
OntModel ontModel= ModelFactory.createOntologyModel();
try {
ontModel.read(new FileInputStream(file), "");
}
catch (FileNotFoundException ex) {
System.out.println("!!!");
};
return ontModel;
};
public static void main(String args[]){
OntModel m = ModelFactory.createOntologyModel();
Testmain test = new Testmain();
m = test.getModel();
String ontoNS = "http://www.mindswap.org#";
OntClass concept = m.getOntClass(ontoNS + "Car");
System.out.println(concept.getLocalName());
}
}
