Answer 1

字符分割出错,java.util.NoSuchElementException,java.util.StringTokenizer.nextToken
没有这样的元素！！

Answer 2

不是的，我有偶尔有时候是可以插入的
如果哪位不嫌烦的话可以帮我看看代码：
<%@ page contentType="text/html; charset=gb2312" language="java" import="java.sql.*"%>
<%@ page import="java.util.*"%>
<jsp:useBean id="DBConnection" scope="page" class="com.raecom.DBConnection"/>
<%
  
   String h=request.getParameter("hours");
   String p=request.getParameter("project");
   String d=request.getParameter("datetime");
   String stractive=new String(request.getParameter("active").getBytes("8859_1"));
   String otse=new String(request.getParameter("otse").getBytes("8859_1"));
   String ot=request.getParameter("ot");
   //out.print(d);
   //if(true)
   //{return;}
   
   ArrayList A1=new ArrayList();
   ArrayList A2=new ArrayList();
   ArrayList A3=new ArrayList();
   ArrayList A4=new ArrayList();
   ArrayList A5=new ArrayList();
   ArrayList A6=new ArrayList();
     StringTokenizer st1 = new StringTokenizer(d,"$$");
   StringTokenizer st2 = new StringTokenizer(p,"$$");
   StringTokenizer st3 = new StringTokenizer(stractive,"$$");
   StringTokenizer st4 = new StringTokenizer(h,"$$");
   StringTokenizer st5 = new StringTokenizer(otse,"$$");
   StringTokenizer st6 = new StringTokenizer(ot,"$$");
   while (st1.hasMoreTokens()) {
      A1.add(st1.nextToken());// 这里依次给赋值
  A2.add(st2.nextToken());
  A3.add(st3.nextToken());
  A4.add(st4.nextToken());
  A5.add(st5.nextToken());
  A6.add(st6.nextToken());

    }
    //然后转成数组
   Object[] arr1=A1.toArray();
   Object[] arr2=A2.toArray();
   Object[] arr3=A3.toArray();
   Object[] arr4=A4.toArray();

   Object[] arr6=A6.toArray();  Connection conn=DBConnection.getConnectionToAccess(application.getRealPath("data/RAE-Systems.mdb"));
  Statement stmt=conn.createStatement(ResultSet.TYPE_SCROLL_INSENSITIVE,ResultSet.CONCUR_READ_ONLY);
  String strname=(String)session.getValue("Use_Name");
   for(int i=0;i<arr1.length;i++)
   {
      String sql="insert into roolbook(Use_Name,Cur_Date,PRO_Name,Active,Pure_hour) values('"+strname+"','"+arr1[i]+"','"+arr2[i]+"','"+arr3[i]+"','"+arr4[i]+"')"; 
      try{
      stmt.executeUpdate(sql);
  }catch(Exception e)
      {
    response.sendRedirect("error.jsp?error=2");
  }
    }
stmt.close();
if(otse!=""||ot!="0")
{
  Statement stmt2=conn.createStatement(ResultSet.TYPE_SCROLL_INSENSITIVE,ResultSet.CONCUR_READ_ONLY);
for(int i=0;i<arr1.length;i++)
   {
      String sql1="insert into roolbook(Use_Name,Cur_Date,PRO_Name,Active,Pure_hour) values('"+strname+"','"+arr1[i]+"','"+arr5[i]+"','"+arr5[i]+"','"+arr6[i]+"')"; 
      try{
      stmt2.executeUpdate(sql1);
  }catch(Exception e)
      {
    response.sendRedirect("error.jsp?error=2");
  }
    }
stmt2.close();
}
if(conn!=null)
{
conn.close();

Answer 3

注意下面这段：while (st1.hasMoreTokens()) {
      A1.add(st1.nextToken());// 这里依次给赋值
  A2.add(st2.nextToken());
  A3.add(st3.nextToken());
  A4.add(st4.nextToken());
  A5.add(st5.nextToken());
  A6.add(st6.nextToken());

    }这种写法必须保证传入的6个参数分割后都有相同数量的元素（准确说是后面5个的元素数量要必须要多于第一个），否则就会遇到你报的那个错误。你应该检查参数分割后的元素是否有足够数量。
