问题与cometd和码头6/7

Question

我正试图开始使用cometd（http://cometd.org/）和6号或7号码头，但我似乎遇到了问题。我有一个蚂蚁脚本将我的代码打包成与wartd 1.1.1二进制文件和jetty二进制文件的战争，这些二进制文件适用于我将部署战争的jetty版本（当我部署到7.1.2.v20100523二进制文件时）当我部署到6.1.24时，jetty 7.1.2.v20100523和6.1.24）。我首先尝试使用版本7.1.2.v20100523进行设置，但是当我尝试部署时，我得到了一个非常长的堆栈跟踪示例：

似乎经历了所有码头二进制文件并抱怨每个类文件。

当我尝试部署到6.1.24时，我得到了

我的web.xml如下所示：

         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"

    </filter-mapping> -->

</web-app>

注意交叉原点过滤器已注释掉。当我试图在6.1.24上运行时，这个类似乎不存在（据我所知，这是正确的行为，是吗？）。

对于noob问题感到抱歉，但有人知道我在这里做错了吗？

Answer 1

好的，好像这里有一些问题需要解决。首先是我在战争中捆绑的码头版本需要改变。我切换到7.0.2.v20100331。其次，我不得不更改部署描述符

<?xml version="1.0" encoding="UTF-8"?>
<web-app 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"
         version="2.5">

    <servlet>
        <servlet-name>cometd</servlet-name>
        <servlet-class>org.cometd.server.continuation.ContinuationCometdServlet</servlet-class>
        <load-on-startup>1</load-on-startup>
    </servlet>
    <servlet-mapping>
        <servlet-name>cometd</servlet-name>
        <url-pattern>/cometd/*</url-pattern>
    </servlet-mapping>

    <servlet>
        <servlet-name>initializer</servlet-name>
        <servlet-class>uk.co.dubit.nexus.comet.BayeuxInitializer</servlet-class>
        <load-on-startup>2</load-on-startup>
    </servlet>

    <filter>
        <filter-name>continuation</filter-name>
        <filter-class>org.eclipse.jetty.continuation.ContinuationFilter</filter-class>
    </filter>
    <filter-mapping>
        <filter-name>continuation</filter-name>
        <url-pattern>/cometd/*</url-pattern>
    </filter-mapping>

</web-app>

最后还有一个额外的步骤，即将战争部署到jetty 6.1.24（这是我最终运行代码的版本），你必须在{{1}中为战争放置一个XML描述符} 目录。我的描述符看起来像

contexts/

之后，我的servlet可以从这个描述符中列出的/ cometd路径访问。
