在tomcat上发布时,请求的资源不可用

标签: java web-services tomcat7

我正在尝试使用tomcat发布一个简单的java Web服务。参考下面的截图,我有 HelloWorld.java ,它是服务接口及其 HelloWorldImpl.java 实现类。

我也创建了 web.xml sun-jaxws.xml

当我右键单击项目时,选择运行方式然后在服务器上运行,我会收到404错误消息,如屏幕截图底部所示。

内部浏览器尝试访问的网址是http://localhost:8081/MySqlConnect/,其中MySqlConnect是项目名称。请注意,我使用8081作为端口号。

我也试过http://localhost:8081/HelloWorld/hello,但它没有用。

我还提供了以下所有文件的代码。

我无法理解我哪里出错了?任何帮助表示赞赏。

HelloWorldImpl.java

package com.mycompany.service;
import javax.jws.WebService;
@WebService(endpointInterface = "com.mycompany.service.HelloWorld", serviceName = "HelloWorld")
public class HelloWorldImpl implements HelloWorld {

    @Override
    public String sayGreeting(String name) {

        return "Greeting " + name + "!";
    }
}

的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/j2ee/dtds/web-app_2_3.dtd">

<web-app>
    <listener>
        <listener-class>
            com.sun.xml.ws.transport.http.servlet.WSServletContextListener
        </listener-class>
    </listener>
    <servlet>
        <servlet-name>hello</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>hello</servlet-name>
        <url-pattern>/hello</url-pattern>
    </servlet-mapping>
    <session-config>
        <session-timeout>120</session-timeout>
    </session-config>
</web-app>

太阳jaxws.xml

<?xml version="1.0" encoding="UTF-8"?>
<endpoints xmlns="http://java.sun.com/xml/ns/jax-ws/ri/runtime"
    version="2.0">
    <endpoint name="HelloWorld" implementation="com.mycompany.service.HelloWorldImpl"
        url-pattern="/hello" />
</endpoints>

根据建议here,我下载了所有库并放在tomcat lib文件夹中,但现在我在日志中收到此错误:

com.sun.xml.ws.transport.http.servlet.WSServletContextListener parseAdaptersAndCreateDelegate
SEVERE: WSSERVLET11: failed to parse runtime descriptor: java.lang.NoSuchMethodError: com.sun.xml.ws.assembler.TubelineAssemblyController: method <init>()V not found
java.lang.NoSuchMethodError: com.sun.xml.ws.assembler.TubelineAssemblyController: method <init>()V not found

如果我将所有库添加到项目中然后尝试运行它,我会收到以下错误:

com.sun.xml.ws.transport.http.servlet.WSServletContextListener parseAdaptersAndCreateDelegate
SEVERE: WSSERVLET11: failed to parse runtime descriptor: com.sun.xml.ws.util.ServiceConfigurationError: com.sun.xml.ws.policy.jaxws.spi.PolicyFeatureConfigurator: Provider com.sun.xml.ws.transport.tcp.policy.TCPTransportFeatureConfigurator is specified in jar:file:/C:/Apache-Tomcat-7/lib/webservices-rt-2.1-b16.jar!/META-INF/services/com.sun.xml.ws.policy.jaxws.spi.PolicyFeatureConfiguratorbut could not be instantiated: java.lang.ClassCastException

请注意: com.sun.xml.ws.policy.jaxws.spi.PolicyFeatureConfigurator但无法实例化:java.lang.ClassCastException

正确的网址是 http://localhost:8081/MySqlConnect/hello ,因为 MySqlConnect 是您的上下文的名称, hello 是网络服务网址。

此外,它还是一个Web服务,以便正确访问它,您可以进行SOAP调用。

但根本原因是由于无法找到课程javax.xml.ws.soap.AddressingFeature$Responses,您的网络应用程序无法启动。

您是否添加了正确的依赖项?如果此类存在,则在这些依赖项中搜索。 ResponseAddressingFeature内部类。
