我把lib下面的jar文件全导进classpath里面去了。但是容然提示错误。源代码：
package wrm;
import java.io.*;
import com.hp.hpl.jena.db.*;
import com.hp.hpl.jena.rdf.model.*;
public class wrmds {
public static void main(String[] args) {
OntModel m = ModelFactory.createOntologyModel( OntModelSpec.OWL_MEM, null);
FirstOntology firstonto=new FirstOntology();
OntDocumentManager mgr = new OntDocumentManager();
OntModelSpec s = new OntModelSpec(OntModelSpec.OWL_DL_MEM);
s.setDocumentManager(mgr);
m = ModelFactory.createOntologyModel(s, null);
m.read(firstonto.MROntoSpace.getOntUrl(),"");
firstonto.MROntology=new MulMROntoModelMgr(m);
String fileName = "D:\\wrm_ds.owl";
FileOutputStream ontOutput = new FileOutputStream(fileName);
m.write(ontOutput);
}
}
提示错误：

请各位大侠帮帮忙啊！
