我从我的tomcat 6.0安装目录中用servle-api.com替换了j2ee.jar:这会产生下面的错误.我现在正试图找出原因.可能是什么问题.

我在配置文件中定义了一个bean:Sempedia-service.xml,如下所示

<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-2.5.xsd">
    <bean id="sempediaSearchService"
        class="com.service.SempediaSearchManager" />


</beans>

我的web.xml指定以下bean:

<context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>/WEB-INF/Sempedia-service.xml,/WEB-INF/Sempedia-persistence.xml</param-value>
</context-param>

<listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

我已经通过互联网和stackoverflow进行了扫描，但我仍然不确定proxypass和proxypassreverse的目的。

为什么我们需要proxypass（而不是使用mod_jk）让apache服务器连接到tomcat？

请问有人吗？

在干净的PC上下载Eclipse Indigo后,当我尝试从http://dl.google.com/eclipse/plugin/3.7 下载并下载SDK和Google插件时,大约35%的时间我开始收到错误.
