W3CHINA.ORG讨论区--Eclipse下解析owl-s文件

学习一个例子。我导入了owl-s包还不够吗？是不是还需要什么？请大家指教！
代码如下：
import org.mindswap.owl.OWLFactory;
import org.mindswap.owl.OWLIndividual;
import org.mindswap.owl.OWLKnowledgeBase;
import org.mindswap.owls.OWLSFactory;
import org.mindswap.owls.process.AtomicProcess;
import org.mindswap.owls.process.Process;
import org.mindswap.owls.process.execution.ProcessExecutionEngine;
import org.mindswap.owls.process.execution.ProcessExecutionListener;
import org.mindswap.owls.profile.Profile;
import org.mindswap.owls.service.Service;
import org.mindswap.query.ValueMap;
import org.mindswap.utils.Utils;
import org.mindswap.wsdl.WSDLOperation;
import org.mindswap.wsdl.WSDLService;

public class RunService {

/**
* @param args
*/
Service service;
Profile profile;
Process process;
WSDLService s;
WSDLOperation op;
String inValue;
String outValue;
ValueMap values;
ProcessExecutionEngine exec;

public RunService() {
   // create an execution engine
   exec = OWLSFactory.createExecutionEngine();

   // Attach a listener to the execution engine
   exec.addExecutionListener(new ProcessExecutionListener() {

    public void setCurrentExecuteService(Process p) {
     System.out.println("Start executing process " + p);
    }

    public void printMessage(String message) {
    }

    public void finishExecution(int retCode) {
     System.out.println("Finished execution " +
         ((retCode == ProcessExecutionListener.EXEC_ERROR)
         ? "with errors" : "successfully"));
    }
   });
}

public void runZipCode() throws Exception {
      OWLKnowledgeBase kb = OWLFactory.createKB();

service = kb.readService("file:G:/Downloads/ZipCodeFinder.owl");
process = service.getProcess();

   // initialize the input values to be empty
   values = new ValueMap();

   values.setDataValue(process.getInput("City"), "College Park");
   values.setDataValue(process.getInput("State"), "MD");

   values = exec.execute(process, values);

   // get the result
   OWLIndividual out = values.getIndividualValue(process.getOutput());

   // display the results
   System.out.println("Executed service '" + service + "'");
   System.out.println("Grounding WSDL: " +
       ((AtomicProcess) process).getGrounding().getDescriptionURL());
   System.out.println("City   = " + "College Park");
   System.out.println("State  = " + "MD");
   System.out.println("Output = ");
   System.out.println(Utils.formatRDF(out.toRDF()));
   System.out.println();
}

public static void main(String[] args) throws Exception {
   RunService test = new RunService();


   try {
    test.runZipCode();
         } catch(Exception e) {
             e.printStackTrace();
         }

}
}
出现下面的问题：
