关于xfire的webservice

huangdh12 2009-12-26 11:07:07

最近用MyEclipse6.5，tomcat5,jdk1.5生成了xfire的webservice 已经生成了wsdl地址
代码如下：





IHelloWorldService.java:

package com.softfz.xfile.test;



public interface IHelloWorldService {

	

	public String sayHello(String name); 

}







HelloWorldServiceImpl.java:

package com.softfz.xfile.test;



public class HelloWorldServiceImpl {

	 public String sayHello(String name){  

		   

		return "hello,"+name;  

	  

	}  

}



web.xml:

<?xml version="1.0" encoding="UTF-8"?>

<web-app xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" version="2.5" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee   http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">

  <servlet>

    <servlet-name>XFireServlet</servlet-name>

    <servlet-class>org.codehaus.xfire.transport.http.XFireConfigurableServlet</servlet-class>

    <load-on-startup>0</load-on-startup>

  </servlet>

  <servlet-mapping>

    <servlet-name>XFireServlet</servlet-name>

    <url-pattern>/services/*</url-pattern>

  </servlet-mapping>

  <welcome-file-list>

    <welcome-file>index.jsp</welcome-file>

  </welcome-file-list>

</web-app>



webservice.xml:

<?xml version="1.0" encoding="UTF-8"?>

<beans xmlns="http://xfire.codehaus.org/config/1.0">

 <service>  

         <name>HelloWorldService</name>  

         <serviceClass>  

             com.softfz.xfile.test.IHelloWorldService  

         </serviceClass>  

         <implementationClass>  

              com.softfz.xfile.test.HelloWorldServiceImpl  

         </implementationClass>  

         <style>wrapped</style>  

         <use>literal</use>  

         <scope>application</scope>  

     </service> 

</beans>

我的调用程序如下：









package com.softfz.xfile.test;



import java.net.MalformedURLException;



import org.codehaus.xfire.XFireFactory;

import org.codehaus.xfire.client.XFireProxyFactory;

import org.codehaus.xfire.service.Service;

import org.codehaus.xfire.service.binding.ObjectServiceFactory;



public class HelloWorldClient {  

	   

	 public static void main(String args[]) {  

	   

	 Service srvcModel = new ObjectServiceFactory()  

	   

	 .create(IHelloWorldService.class);  

	   

	 XFireProxyFactory factory = new XFireProxyFactory(XFireFactory  

	   

	 .newInstance().getXFire());  

	   

	 String helloWorldURL = "http://localhost:8080/test/services/HelloWorldService";  

	   

	 try {  

	   

	 IHelloWorldService srvc = (IHelloWorldService) factory.create(  

	   

	 srvcModel, helloWorldURL);  

	   

	 System.out.print(srvc.sayHello("dennis"));  

	   

	 } catch (MalformedURLException e) {  

	   

	 e.printStackTrace();  

	   

	 }  

	   

	 }  

	   

	 }

调用的时候出错如下：



Exception in thread "main" org.codehaus.xfire.XFireRuntimeException: Could not invoke service.. Nested exception is org.codehaus.xfire.fault.XFireFault: Illegal argument invoking 'com.softfz.xfile.test.IHelloWorldService.sayHello(java.lang.String)': object is not an instance of declaring class

	at com.softfz.xfile.test.HelloWorldClient.main(HelloWorldClient.java:30)

请问这是啥原因？
生成的wsdl串如下：
