对该文件调用API中的类库进行操作，最重要的是如下几段代码：
  
OWLKnowledgeBase kb = OWLFactory.createKB();

service = kb.readService("http://www.mindswap.org/2004/owl-s/1.1/ZipCodeFinder.owl");
  
process = service.getProcess();     // 读取服务的process

// 输入初始值为0，输入值为"College Park"和"MD"，函数values.setDataValue得到这两个值，调用服务，并将结果输出。

values = new ValueMap();
  
values.setDataValue(process.getInput("City"), "College Park");  

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

values = exec.execute(process, values);

完整代码如下：

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 {
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("http://www.mindswap.org/2004/owl-s/1.1/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();
        }

}

}

在ECLISPE下运行，得到输出：

Start executing process http://www.mindswap.org/2004/owl-s/1.1/ZipCodeFinder.owl#ZipCodeFinderProcess
Finished execution successfully
Executed service 'http://www.mindswap.org/2004/owl-s/1.1/ZipCodeFinder.owl#ZipCodeFinderService'
Grounding WSDL: http://www.tilisoft.com/ws/LocInfo/ZipCode.asmx?WSDL
City   = College Park
State  = MD
Output =
   ZipCode:
     zip: 20740

同样，对http://www.mindswap.org/2004/owl-s/1.1/BookFinder.owl和http://www.mindswap.org/2004/owl-s/1.1/Dictionary.owl等描述的服务进行操作，也可以得到正确的输出。
