Answer 1

看来是连接被拒绝了，检查下webservice的url！
学习XFire可以去它的官网，那里有user's Guide

Answer 2

基本就是按照http://wenku.baidu.com/link?url=CSmUZGJB3_OKOsGLty7pP2G9703gGBV8rimJIWK0b8WYSMRlrLLwSJ2sGQslxmd_WueRrQLhzDQs5bYKuuKM-U6VQuO0dkzJyGLJd-XFcMe这个链接上的例子来的，除了项目名字不一样。
我贴出来吧、
这个是web.xml<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE web-app   
    PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"   
    "http://java.sun.com/dtd/web-app_2_3.dtd">
<web-app>  <servlet>
    <servlet-name>XFireServlet</servlet-name>
    <display-name>XFire Servlet</display-name>
    <servlet-class>org.codehaus.xfire.transport.http.XFireConfigurableServlet</servlet-class>
  </servlet>  <servlet-mapping>
    <servlet-name>XFireServlet</servlet-name>
    <url-pattern>/servlet/XFireServlet/*</url-pattern>
  </servlet-mapping>  <servlet-mapping>
    <servlet-name>XFireServlet</servlet-name>
    <url-pattern>/services/*</url-pattern>
  </servlet-mapping></web-app>
这个是services.xml，在web-inf/xfire下
<beans xmlns="http://xfire.codehaus.org/config/1.0">
  <service>
    <name>SayHiService</name>
    <namespace>http://cn.com.pansky/SayHiService</namespace>
    <serviceClass>cn.com.pansky.webservice.xfire.study.SayHiService</serviceClass>
    <implementationClass>cn.com.pansky.webservice.xfire.study.SayHiServiceImpl</implementationClass>
  </service>
</beans>
这个是接口package cn.com.pansky.webservice.xfire.study;public interface SayHiService {
public String sayHi(String name);
}这是实现类package cn.com.pansky.webservice.xfire.study;public class SayHiServiceImpl implements SayHiService{
  public String sayHi(String name){
    if(name==null){
      return "连名字也不肯告诉我吗？";
    }
    return name+", 你吃了吗？没吃回家吃去吧。";
  }   public String 不告诉你(){
    return "我的名字不告诉你！";
  }
}这是客户端访问代码public class SayHiClient { /**
 * @param args
 */
  public static void main(String args[]) {
    String serviceURL = "http://localhost/webServiceTest/services/SayHiService";
    Service serviceModel = new ObjectServiceFactory().create(SayHiService.class,null,"http://cn.com.pansky/SayHiService",null);     XFireProxyFactory serviceFactory = new XFireProxyFactory();     try{
      SayHiService service = (SayHiService) serviceFactory.create(serviceModel, serviceURL);
      Client client = Client.getInstance(service);
      //client.addOutHandler(new OutHeaderHandler());       // disable timeout
      client.setProperty(CommonsHttpMessageSender.HTTP_TIMEOUT, "1");       String hello = service.sayHi("张山疯");
      System.out.println("服务器对[张山疯] 的回答是：" + hello );       hello = service.sayHi(null);
      System.out.println("服务器胡言乱语说：" + hello );     } catch (MalformedURLException e) {
      e.printStackTrace();
    }
  }}

Answer 4

官网纯英文，真心无力。。
别想的那么难
 String serviceURL = "http://localhost/webServiceTest/services/SayHiService";
你部署在tomcat中吗
端口号什么的都配好了吗

Answer 5

http://localhost这样写默认是80端口吧，这个不是乱写的。

端口号什么的都配好了吗例子是localhost没加端口，不管我配127.0.0.1:8080、还是localhost:8080、还是我的联网IP192.168.90.11:8080都是报一样的错:

Answer 7

你 url 看看地址是否打得开。 。

Answer 8

不行的，我用http://localhost:8080/webServiceTest/services/SayHiService的话就出来Invalid SOAP request.
