在我的 GWT 项目中，servlet 定义在 war/WEB-INF/web.xml 文件中；但是当我运行它时，Jetty 会为每个人提供一个 ClassNotFoundException ；像下面的一个：

java.lang.ClassNotFoundException: tr.gov.gib.mhdb.vimer.vimerapp.server.CSGWTDownloadServletImpl    at

编辑：还有这个：javax.servlet.UnavailableException: tr.gov.gib.mhdb.vimer.vimerapp.server.CSGWTDownloadServletImpl

我的 web.xml 是这样的：

    <?xml version="1.0" encoding="UTF-8"?>

    <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">

     <servlet>
        <servlet-name>generalService</servlet-name>
        <servlet-class>tr.gov.gib.mhdb.vimer.vimerapp.server.GeneralServiceImpl</servlet-class>
     </servlet>
     <servlet>
        <servlet-name>fetchTree</servlet-name>
        <servlet-class>tr.gov.gib.mhdb.vimer.vimerapp.server.MyTreeServiceImpl</servlet-class>
     </servlet>
     <servlet-mapping>
        <servlet-name>generalService</servlet-name>
        <url-pattern>/tr.gov.gib.mhdb.vimer.vimerapp.Vimer/generalService</url-pattern>

     </servlet-mapping>
     <servlet-mapping>
        <servlet-name>fetchTree</servlet-name>
        <url-pattern>/tr.gov.gib.mhdb.vimer.vimerapp.Vimer/fetchTree</url-pattern>
     </servlet-mapping>

</web-app>

您可能忘记在 Service 类中添加 @RemoteServiceRelativePath("name") ，其中 name 与<servlet-name>.
