tomcat - Jax-ws war 部署，但在 tomcat 上给出 404

标签 tomcat jax-ws

首先，我查看了建议的类似问题 - 因为这显然是一个相当普遍的问题 - 但尚未找到答案。我哪里出错了？下载最新的 JAXWS-RI 并手动复制所有 .jar 文件。然后拼凑了一个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/dtd/web-app_2_3.dtd">
<web-app>
    <listener>
        <listener-class>
           com.sun.xml.ws.transport.http.servlet.WSServletContextListener
        </listener-class>
    </listener>
    <servlet>
        <servlet-name>HelloWorldTomcatService</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>HelloWorldTomcatService</servlet-name>
        <url-pattern>/HelloWorldTomcatService</url-pattern>
    </servlet-mapping>
    <session-config>
        <session-timeout>30</session-timeout>
    </session-config>
    </web-app>

和一个 sun-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="HelloWorldTomcatService" implementation="com.myservice.ws.Hello" url-pattern="/HelloWorldTomcatService"/>
</endpoints>

和几个java文件

package com.myservice.ws;
import javax.jws.WebMethod;
import javax.jws.WebService;
@WebService
public interface WebServiceInterface {
    @WebMethod
    String printMessage();
}

package com.myservice.ws;
import javax.jws.WebService;

@WebService(endpointInterface = "com.myservice.ws.WebServiceInterface")
public class Hello implements WebServiceInterface{
    @Override
    public String printMessage() {
        return "message";
    }
}

我把这四个文件放在合适的目录结构中，在eclipse中建了一个war文件，复制到Tomcat的webapps文件夹下。 war 爆发并出现在管理器控制台上，但它没有启动，所有在浏览器中访问它的尝试也都失败了。

更新:

这是来自 catalina 日志的异常(exception)情况。

最佳答案

以防万一有人好奇:我遇到的问题是 web.xml 的 header 与我使用的 Tomcat 版本不兼容 - 或者已弃用，我不知道。

现在有效的 header 是:

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://java.sun.com/xml/ns/j2ee"
      xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
      xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee 
      http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"
      version="2.4">
...

还有一个警告说 hk2-core.jar 丢失了。如果我先解决 xml 问题，我不确定这是否会成为问题，但这是一个很好的收获，所以，支持 Kolossus。
