在Tomcat上部署WebService:WS不可用：404错误

Question

这是我在stackoverflow中的第一个问题！WOW：）

在这个问题上，我简直不知所措：（我有一个简单的helloworld Web服务，构建WAR文件并将其部署在本地主机上的tomcat（8.0.35）上。明确地说：我刚刚写了一个类，用@WebService注释；然后我写了网络。xml和sun jaxws。xml；我什么都没做！这足以让该类成为Web服务吗？我是否错过了另一步？

问题：网址：localhost:8080/endpointname/url-pattern没有显示我的网络服务的定义，因为它在我跟随编写服务的链接中意味着：http://www.mkyong.com/webservices/jax-ws/deploy-jax-ws-web-services-on-tomcat/.我只得到一个胖的404 Eror。这是我的构建文件：

<?xml version="1.0" encoding="UTF-8"?>
<project name="test_WS" default="deploy" basedir=".">
<property name="project-name" value="${ant.project.name}" />
<property name="war-file-name" value="${project-name}.war" />

    </fileset>  
</path>

<target name="init">
    <mkdir dir="${webinf.dir}/classes" />
    <mkdir dir="${build-directory}/classes" />
</target>

<target name="deploy" depends="war">
    <copy file="${build-directory}/${war-file-name}" todir="${local.deploy.dir}" />
    <copy file="${build-directory}/${war-file-name}" todir="${shared.deploy.dir}" />
</target>

<!-- war  -->
<target name="war" depends="build">
    <war warfile="${build-directory}/${war-file-name}" webxml="${web-xml-file}">
        <classes dir="${build-directory}/classes" />
        <fileset dir="${web-directory}">
            <!-- exclude webxml as it is attribute of the war tag -->
            <exclude name="WEB-INF/web.xml" />
        </fileset>
        <manifest>
            <attribute name="Built-On" value="${build-info.current-date}" />
            <attribute name="Built-At" value="${build-info.current-time}" />
        </manifest>
    </war>
</target>   

<target name="build" depends="clean">
    <javac includeantruntime="false" srcdir="${source-directory}" destdir="${build-directory}/classes">
    </javac>
</target>


<!-- clean --> 
 <target name="clean" description="Prepare for clean build">
    <delete dir="${webinf.dir}/classes" />
    <delete dir="${build-directory}" />
    <mkdir dir="${build-directory}" />
    <mkdir dir="${build-directory}/classes" />
</target>
</project>

这是我的太阳。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="HalloAPI"
        implementation="saab.javabeans.Hallo"
        url-pattern="/sayhello" >
    </endpoint>
</endpoints>

这是API：

@WebService
public interface HalloAPI {
     String sayHello(String name);
}

为什么tomcat说：“HTTP状态404- /HalloAPI/sayhello”？发布方面有什么问题或遗漏吗？我的意思是，如果我使用glassfish服务器，它会部署并向我显示测试器和wsdl。但是在tomcat上部署...我得到404。

这是我的网站。xml:

<web-app version="2.5" 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_2_5.xsd">

<url-pattern>/sayhello</url-pattern>
</servlet-mapping>
<session-config>
 <session-timeout>20</session-timeout>
</session-config>
</web-app>

Happy I：我将所需的jaxws JAR移到了web inf/lib中。现在Tomcat不会在部署时抛出错误。但该服务仍然不可用。据我所知：tomcat/lib中的jaxws JAR混淆了类加载器。所以我把他们塞进了战争。下面是部署协议：

问题依然存在：服务不可用；状态：404提前感谢您的帮助。

更改你的com。太阳xml。ws。运输http。Servlet。WSServlet到com。太阳xml。ws。运输http。servlet。WSServlet在你的网站上。xml
