我在.jar中有xxx.class，但是当我启动tomcat时，它告诉我java.lang.ClassNotFoundException

Question

在.jar包中

并在web.xml中

<?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"
    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" id="WebApp_ID" version="3.0">
    <display-name>ftest</display-name>    
    <listener>
        <listener-class>com.sun.xml.ws.transport.http.servlet.WSServletContextListener</listener-class>
    </listener>

    <servlet>
        <servlet-name>WebServices</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>WebServices</servlet-name>
        <url-pattern>/ws/*</url-pattern>
    </servlet-mapping>
</web-app>

当我按下ctrl并右键单击它时，它将把我定向到.class文件，但是当我启动tomcat时，它出错并抛出java.lang.ClassNotFoundException：

java.lang.ClassNotFoundException: com.sun.xml.ws.transport.http.servlet.WSServletContextListener

我犯了什么错误吗？ 我对此很困惑

Answer 1

WSServletContextListener （Tomcat寻找的类）实现ServletContextAttributeListener ，这不是默认Tomcat安装的一部分。 因此，为了解决此问题，您需要将jaxws-rt jar复制到Tomcat/lib文件夹中。
