java - Web 服务连接被拒绝

Question

我正在尝试连接到我的网络服务，但问题是我的连接被拒绝了。我在运行 Web 服务的服务器上运行 WAMP，并且在 Eclipse 上运行 Apache Tomcat8。这是堆栈跟踪:

这里也是客户端:

import java.util.*;
import java.io.*;

import javax.xml.rpc.ServiceException;
public class message {
    public static void main(String[] args) throws IOException
    {
        Scanner in = new Scanner(System.in);

        System.out.println("Enter a word: ");
        String a = in.next();

        WebserviceServiceLocator locator = new WebserviceServiceLocator();
        WebserviceSoapBindingStub stub;
        try {
            stub = (WebserviceSoapBindingStub)locator.getwebservice();
            System.out.println(stub.echo(a));
    } catch (ServiceException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
   }
}

Echo 只返回您输入的内容。

我在使用部署在 glassfish 上的 web 服务时遇到了类似的错误，这是因为我之前终止了 glassfish 进程，因此服务器停止运行。这就是无法建立客户端和 web 服务之间的连接的原因。检查您的 Tomcat 服务器是否仍在运行。
