Answer 1

一、 在{TOMCAT_HOMT}/conf/web.xml打开下列两项的注释
1、
<servlet>
<servlet-name>invoker</servlet-name>
<servlet-class>
org.apache.catalina.servlets.InvokerServlet
</servlet-class>
<init-param>
<param-name>debug</param-name>
<param-value>0</param-value>
</init-param>
<load-on-startup>2</load-on-startup>
</servlet>
2、
<servlet-mapping>
<servlet-name>invoker</servlet-name>
<url-pattern>/servlet/*</url-pattern>
</servlet-mapping>
并将1项中的<load-on-startup>2</load-on-startup>去掉
二、修改{TOMCAT_HOME}/conf/context.xml
将<Context> 修改为<Context privileged="true">
三、在eclipse3.3中的Servers 项目中找到配置文件server.xml中 在描述项目的Host标签中添加属性 privileged="true"

Answer 2

Apache Tomcat本地库,在生产环境中不存在java.library。路径:D:\ Java \ jdk1.6.0_10 \ bin \程序文件;F:\ Tomcat 6.0 \ bin

配置环境变量

Answer 3

应该是有antlr.jar有多个，删除掉低版本的

Answer 4

最简单的方法换一个TomCat，重新安装。

Answer 5

对象不存在或类加载不对。
