java - Tomcat + NetBeans + JAX-WS 示例项目导致 javax.xml.ws.WebServiceException

Question

我在 NetBeans 中创建了一个简单的 Java EE 项目(文件 -> 新建项目 -> Java Web -> Web 应用程序)。

在新创建的项目中，我添加了一个名为“CesaService”的 Web 服务。这是来源:

package com.convista.jcesa.webservice;

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

@WebService(serviceName = "CesaService")
public class CesaService {

    @WebMethod(operationName = "hello")
    public String hello(@WebParam(name = "name") String txt) {
        return "Hello " + txt + " !";
    }
}

NetBean 然后生成以下文件:

太阳-jaxws.xml:

<?xml version="1.0" encoding="UTF-8"?>
<endpoints version="2.0" xmlns="http://java.sun.com/xml/ns/jax-ws/ri/runtime">
  <endpoint implementation="com.convista.jcesa.webservice.CesaService" name="CesaService" url-pattern="/CesaService"/>
</endpoints>

web.xml:

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="3.0" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd">
    <listener>
        <listener-class>com.sun.xml.ws.transport.http.servlet.WSServletContextListener</listener-class>
    </listener>
    <servlet>
        <servlet-name>CesaService</servlet-name>
        <servlet-class>com.sun.xml.ws.transport.http.servlet.WSServlet</servlet-class>
        <load-on-startup>1</load-on-startup>
    </servlet>
    <servlet-mapping>
        <servlet-name>CesaService</servlet-name>
        <url-pattern>/CesaService</url-pattern>
    </servlet-mapping>
    <session-config>
        <session-timeout>
            30
        </session-timeout>
    </session-config>
</web-app>

我的服务器是出厂的 Tomcat 7.0.22.0。当我启动项目时，出现以下错误:

你知道是什么原因造成的吗？我不想要一个类 com.convista.jcesa.webservice.jaxws.Hello 并且不明白它在哪里被引用。

提前致谢!

Answer 1

 public String hello(@WebParam(name = "name") String txt) {

应该是

 public String hello(@WebParam(name = "name") String name) {
