tomcat5和tomcat6配置ssi支持的区别

在tomcat中配置ssi支持的时候，tomcat 5和tomcat 6是有区别的，先说相同的地方，找到$CATALINA_HOME/conf/web.xml中的下面两段被注释掉的部分，并将取消注释。

Java代码

1. <!--   
2.     <servlet>   
3.         <servlet-name>ssi</servlet-name>   
4.         <servlet-class>   
5.           org.apache.catalina.ssi.SSIServlet   
6.         </servlet-class>   
7.         <init-param>   
8.           <param-name>buffered</param-name>   
9.           <param-value>1</param-value>   
10.         </init-param>   
11.         <init-param>   
12.           <param-name>debug</param-name>   
13.           <param-value>0</param-value>   
14.         </init-param>   
15.         <init-param>   
16.           <param-name>expires</param-name>   
17.           <param-value>666</param-value>   
18.         </init-param>   
19.         <init-param>   
20.           <param-name>isVirtualWebappRelative</param-name>   
21.           <param-value>0</param-value>   
22.         </init-param>   
23.         <load-on-startup>4</load-on-startup>   
24.     </servlet>   
25. -->   
26. <!--   
27.     <servlet-mapping>   
28.         <servlet-name>ssi</servlet-name>   
29.         <url-pattern>*.shtml</url-pattern>   
30.     </servlet-mapping>   
31. -->  

<!--    <servlet>        <servlet-name>ssi</servlet-name>        <servlet-class>          org.apache.catalina.ssi.SSIServlet        </servlet-class>        <init-param>          <param-name>buffered</param-name>          <param-value>1</param-value>        </init-param>        <init-param>          <param-name>debug</param-name>          <param-value>0</param-value>        </init-param>        <init-param>          <param-name>expires</param-name>          <param-value>666</param-value>        </init-param>        <init-param>          <param-name>isVirtualWebappRelative</param-name>          <param-value>0</param-value>        </init-param>        <load-on-startup>4</load-on-startup>    </servlet>--><!--    <servlet-mapping>        <servlet-name>ssi</servlet-name>        <url-pattern>*.shtml</url-pattern>    </servlet-mapping>-->

然后对于tomcat 5需要将$CATALINA_HOME/server/lib下的servlets-ssi.renametojar文件改名成servlets- ssi.jar，否者会出现java.lang.ClassNotFoundException: org.apache.catalina.ssi.SSIServlet错误。
而对于tomcat 6 需要将$CATALINA_HOME/conf/context.xml中 结点添加一个属性 privileged=&quot;true&quot;变成，如果没有加的话则会出现java.lang.SecurityException: Filter of class org.apache.catalina.ssi.SSIServlet is privileged and cannot be loaded by this web application 错误。
