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") ;
}
}
getting following error -
