Gwt servlet 在 tomcat 上失败

Question

我可以在码头本地访问我的 Servlet（作为 googlewebtoolkit 运行），

但是当我在Tomcat中部署我的应用程序时

192.0.1.23:8080/test/servlet

并试图运行它，它什么也没显示

这是我的文件 web.xml：

<servlet>  
 <servlet-name>PrintReport</servlet-name>  
 <servlet-class>com.testre.test.server.PrintReport</servlet-class>  
</servlet>  
<servlet-mapping>  
 <servlet-name>PrintReport</servlet-name>  
 <url-pattern>/test/servlet</url-pattern>  
</servlet-mapping>  

我的服务端文件

        void sendPDF(HttpServletResponse response, byte[] bytes, String name) throws IOException
    {
        ServletOutputStream stream = null;

        stream = response.getOutputStream();
        response.setContentType("application/pdf");
        response.addHeader("Content-Type", "application/pdf");
        response.addHeader("Content-Disposition", "inline; filename=" + name);
        response.setContentLength((int) bytes.length);
        stream.write(bytes);
        stream.close();
    } 
}

您将战争放置在错误的位置。

C:\apache-tomcat-7.0.40\webapps\test\war

将war文件夹的所有内容直接放在C:\apache-tomcat-7.0.40\webapps\test文件夹下，去掉多余的war文件夹。
