Question

我在Eclipse里运行一个java程序一直出现这个错，是什么原因啊？

服务器出现这个错误，如下：

2008-9-20 19:42:27 org.apache.catalina.core.StandardContext filterStart
严重: Exception starting filter CharacterFilter
java.lang.Error: Unresolved compilation problem:
The method init(FilterConfig) of type CharacterFilter must override a superclass method

中间的省略，字数过长。。。
2008-9-20 19:42:27 org.apache.catalina.core.StandardContext filterStart
严重: Exception starting filter SecurityFilter
java.lang.Error: Unresolved compilation problem:
The method init(FilterConfig) of type SecurityFilter must override a superclass method

2008-9-20 19:42:27 org.apache.catalina.core.StandardContext start
严重: Error filterStart
2008-9-20 19:42:27 org.apache.catalina.core.StandardContext start
严重: Context [/book] startup failed due to previous errors
2008-9-20 19:42:27 org.apache.catalina.core.StandardContext addApplicationListener

Answer 1

The method init(FilterConfig) of type CharacterFilter must override a superclass method
这两个类CharacterFilter SecurityFilter要覆盖init(FilterConfig)方法？

Answer 2

你还不如把程序贴出来~这样更容易找~
