Question

你好我正在尝试用Java设置一个简单的WSDL程序，但我得到以下错误，任何建议？我是相当新的，这个程序是我的第一个。

谢谢，

package de.vs.webServices.clientSide;

import java.net.URL;
import java.util.Scanner;

import javax.xml.namespace.QName;
import javax.xml.ws.Service;

import de.vs.webServices.serverSide.ZeichenketteInt;

public class ZeichenketteClient {

public static void main(String[] args) throws Exception {

URL url = new URL("http://localhost:9999/vs/Zeichenkette?wsdl");

QName qname = new       QName("http://serverSide.webServices.vs.de/","ZeichenketteImplService");

Service service = Service.create(url, qname);

ZeichenketteInt zeichenketteInt = service.getPort(ZeichenketteInt.class);

Scanner sc = new Scanner(System.in);
int nr=0;
do {
    System.out.println("Waehlen Sie die Nummer eines Befehls oder 0 um das Programm zu beenden: ");
    System.out.println("1. Zeichen Doppeln");
    System.out.println("2. Zeichenkette Verdoppeln");
    System.out.println("3. ZeichenketteSpiegeln");
    System.out.println("4. ZeichenketteLange");
    nr = sc.nextInt();
    String zeichenkette = null;
    switch (nr) {
    case 1:
        System.out
                .println("Schreiben Sie die gewunschte Zeichenkette: ");
        zeichenkette = sc.next();
        System.out.println("Ergebnis: "
                + zeichenketteInt.zeichenDoppeln(zeichenkette));
        break;
    case 2:
        System.out
                .println("Schreiben Sie die gewunschte Zeichenkette: ");
        zeichenkette = sc.next();
        System.out.println("Ergebnis: "
                + zeichenketteInt.zeichenKetteVerdoppeln(zeichenkette));

        break;
    case 3:
        System.out
                .println("Schreiben Sie die gewunschte Zeichenkette: ");
        zeichenkette = sc.next();
        System.out.println("Ergebnis: "
                + zeichenketteInt.zeichenKetteSpiegeln(zeichenkette));
        break;
    case 4:
        System.out
                .println("Schreiben Sie die gewunschte Zeichenkette: ");
        zeichenkette = sc.next();
        System.out.println("Ergebnis: "
                + zeichenketteInt.zeichenKetteLange(zeichenkette));
        break;
    }
} while (nr!=0);
sc.close();

}}

这是我得到的错误：

错误的一部分说：“拒绝：连接” 告诉你服务器（本例中为localhost）拒绝了你的连接请求。

我会检查URI：http://localhost:9999/vs/Zeichenkette?wsdl实际上是否返回了一个WSDL文档。只需在网络浏览器中打开它，看看你得到了什么。如果浏览器无法打开它，Java也不能。一旦浏览器打开它，Java应该没有问题（虽然偶尔发生浏览器读取它并且Java中的权限阻止你，这似乎不是这些情况之一）。

然后我建议确保服务器端口是开放的（IPTables，AV，这样的东西可以阻止它）。请注意，这可能不是您的问题，因为错误是读取WSDL。我正在展望WSDL加载之后。

无法访问WSDL
