Tomcat: Error filterStart解决办法

Tomcat: Error filterStart解决办法

现状：

把filter\SetCharacterEncodingFilter.class放在web-inf\classes目录

在web.xml中添加

    <welcome-file-list>
        <welcome-file>index.html</welcome-file>
        <welcome-file>index.htm</welcome-file>
        <welcome-file>index.jsp</welcome-file>
    </welcome-file-list>
 
  <filter>
   <filter-name>Set Character Encoding</filter-name>
   <filter-class>filters.SetCharacterEncodingFilter</filter-class>
   <init-param>
    <param-name>encoding</param-name>
    <param-value>GBK</param-value>
   </init-param>
  </filter>

  <filter-mapping>
   <filter-name>Set Character Encoding</filter-name>
   <url-pattern>/*</url-pattern>
  </filter-mapping>

后，启动tomcat5.0.28，出现

2007-3-13 17:43:46 org.apache.catalina.core.StandardContext start
严重: Error filterStart
2007-3-13 17:43:46 org.apache.catalina.core.StandardContext start
严重: Context startup failed due to previous errors



解决办法：

c:\> cd 主页目录\web-inf\classes

c:\> jar cvf   filters.jar   filters

形成filters.jar文件，把它放在 tomcat\common\lib下，重新启动tomcat，问题解决！
