线程“main”中的异常 java.lang.NoClassDefFoundError: org/apache/commons/discovery/tools/DiscoverSingleton

Question

在这里，我试图通过 wsdl 使用 webservices 进行调用，同时运行代码时出现以下异常。也显示测试代码，请帮帮我。谢谢。

 import org.apache.axis.client.Service;
import org.apache.axis.client.Call;
import org.apache.commons.codec.binary.Base64;

import javax.xml.namespace.QName;
import java.net.URL;


public class WebTest {
    Service service = null;

    String endpoint = "http://mytest.com/test/Signup.jws";
    String userName =  "globel";
    String userPw =  new String(Base64.decodeBase64("Z23fG46732345FG=".getBytes()));;

    public WebTest() {
        try {
            service = new Service();
            System.out.println("*** executed successfully ");
        } catch (Exception e) {
            System.out.println("Exception - " + e.getMessage());
        }
    }
    public void testWeb(String f1, String f2, String f3, int itemcode, String f4){
    try {
            Call call = (Call)service.createCall();
            call.setTargetEndpointAddress(new URL(endpoint));
            call.setOperationName(new QName("emp"));
            call.setUsername(userName);
            call.setPassword(userPw);
            Object[] params = new Object[5];
            params[0] = new String(f1);
            params[1] = new String(f2);
            params[2] = new String(f3);
            params[3] = new Integer(itemcode);
            params[4] = new String(f4); 
            call.invoke(params);

        } catch (Exception e) {
             System.out.println("Exception - " + e.getMessage());
        }
    }

    public static void main(String[] args) {
        String orderDate = "03-Jan-2013";
        WebTest webtest= new WebTest() ;
        webtest.testWeb("rayban","aviator",orderDate,82724,"113000") ;
    }

}

得到以下错误 -

Answer 1

对于 maven 用户：将 commons-discovery 依赖项添加到您的 pom.xml 文件中，例如

<dependency>
    <groupId>commons-discovery</groupId>
    <artifactId>commons-discovery</artifactId>
    <version>0.4</version>
</dependency>

Answer 2

将 discovery-0.4.jar 添加到我的代码中，它解决了我的问题。
