JBoss AS 7写一个简单的web service

[CyberKnightGIC]

我按jboss的官方文档这么做：
1.写一个pojo类，声明一个方法如下：

package com.sample;

import javax.jws.WebMethod;
import javax.jws.WebService;

@WebService
public class HelloWorld {
@WebMethod
public void sayHello(){
System.out.print("Hello");
}
}

之后web.xml是这么写的：
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="WebApp_ID" version="2.5">
<display-name>Hello</display-name>

<servlet>
<servlet-name>HelloService</servlet-name>
<servlet-class>com.sample.HelloWorld</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>HelloService</servlet-name>
<url-pattern>/hello</url-pattern>
</servlet-mapping>

</web-app>

然后部署到jboss AS 7没有问题，但是访问的时候报错：
exception

javax.servlet.ServletException: Class com.sample.HelloWorld is not a Servlet

org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:102)

掉了哪一步吗？JBossWS不支持不写wsdl用pojo实现吗？

Class com.sample.HelloWorld is not a Servlet 找不到Action类。你的思路还是没转换过来，依然是servlet的思路假web.xml配置。
web.xml配置 <context-param>
<param-name>javax.faces.CONFIG_FILES</param-name>
<param-value>/WEB-INF/faces-config.xml</param-value>
</context-param>

然后在faces-config.xml配置。
action层;@ManagedBean(name = "XXX")
@SessionScoped
public class HelloWorld {
public void sayHello(){
System.out.print("Hello");
}
}

我走过 把EJB发布成webservice的， 就是在EJB 3.0上面加上@webservice注解 然后是用javaws提供的注解就ok
