Question

在我的GWT项目中，servlet在war / WEB-INF / web.xml文件中定义;但是当我运行它时，Jetty为它们中的每一个提供了一个ClassNotFoundException;如下所示：

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

编辑：还有：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"

        <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>中的名称相同。

运行时Gwt java.lang.ClassNotFoundException错误
