修改了web.xml中的
程序代码：
<filter>
        <filter-name>SetCharsetEncodingFilter</filter-name>
        <filter-class>com.bbs.util.SetCharacterEncodingFilter</filter-class>
      

        <!--

        <filter-class>class>
         -->
        <init-param>
            <param-name>encoding</param-name>
            <param-value>UTF-8</param-value>
        </init-param>
    </filter>
   

    <filter>
        <filter-name>CloseSessionFilter</filter-name>
        <filter-class>com.bbs.util.CloseSessionFilter</filter-class>
        <!--

        <filter-class>class>
        -->
    </filter>

tomcat不报错了。

可是运行程序的时候抛出
程序代码：
exception


javax.servlet.ServletException: com.bbs.web.struts.action.SubjectAction.editbyadmin(org.apache.struts.action.ActionMapping, org.apache.struts.action.ActionForm, javax.servlet.http.HttpServletRequest, javax.servlet.http.HttpServletResponse)
    org.apache.struts.action.RequestProcessor.processException(RequestProcessor.java:523)
    org.apache.struts.action.RequestProcessor.processActionPerform(RequestProcessor.java:421)
    org.apache.struts.action.RequestProcessor.process(RequestProcessor.java:224)
    org.apache.struts.action.ActionServlet.process(ActionServlet.java:1194)
    org.apache.struts.action.ActionServlet.doGet(ActionServlet.java:414)
    javax.servlet.http.HttpServlet.service(HttpServlet.java:689)
    javax.servlet.http.HttpServlet.service(HttpServlet.java:802)
    com.bbs.util.CloseSessionFilter.doFilter(CloseSessionFilter.java:37)
    com.bbs.util.SetCharacterEncodingFilter.doFilter(SetCharacterEncodingFilter.java:91)


root cause

异常。closeSessionFilter.java 37行
try{
            chain.doFilter((HttpServletRequest)request, (HttpServletResponse)response);
        }
