  1.   

    我的配置是这样的
    CLASSPATH:.;C:\ j2sdk1.5.0\lib\dt.jar;C:\ j2sdk1.5.0\lib\tools.jar
    JAVA_HOME:  C:\j2sdk1.5.0
    Path:       ;%JAVA_HOME%\bin
    tomcat:     c:\Tomcat 5.0
    -------------
    更新数据代码是这样的：
    <%@ page contentType="text/html; charset=gb2312" import="java.util.*"%>
    <%@ page import="auth.*"%>
    <%@ page import="java.sql.*"%>
    <jsp:useBean id="DBC" scope="page" class="auth.DBCurrent"/>
    <%request.setCharacterEncoding("gb2312");
    int id = Integer.parseInt(request.getParameter("id"));//编辑id号
    int new_state = Integer.parseInt(request.getParameter("new_states"));//新状态
    String sql = "update project set project_state_flow="+new_state+"  where project_id="+id+"";
    int err = DBC.doUpdate(sql);
    out.println(err);
    if (err!=1){%>
    <script>
    alert("错误提示:重报失败!\n请重新再试一次，如果仍有问题请联系管理员！");
    history.back();
    </script>
    <%}else{%>
    <script>
    alert('提示:重报成功!');
    history.back();
    </script>
    <%}%>
    -----------------
    运行时出现这样的错误
      

  2.   

    更新类是这样写的
      public int doUpdate(String sql){
        int updateNum = 0;
        try{
          stmt = conn.createStatement();
          updateNum = stmt.executeUpdate(sql);
        }catch(SQLException ex){
          System.out.println("[系统异常]更新数据时:"+ex);
        }
        return updateNum;
      }
    以前在tomcat4.1下运行正常，现在我换在tomcat5下却出现
    2006-5-3 16:01:42 org.apache.jasper.runtime.PageContextImpl release
    警告: Internal error flushing the buffer in release()
    请问是什么原因，如何解决
      

  3.   

    你把你的tomcat下的work目录删了，再试试，看看怎样
      

  4.   

    程序是正确的
    你在reload一下你的目录。
