Invalid chunk ignored
下面是一段分页程序,请大家仔细看一下,只要看我标记的地方就行。

   <%  
  int   i;  
  int   ipage=5;   //分页单位  
  int   allpage;   //总页数  
  int   pages;   //接受的页码变量  
  int   cpage=1;   //当前页  
  int   spage;   //开始页  
  int   allCol=0;
  Vector   v=null;
  
  //数据库连接声明
     Connection   conn=null;
     java.lang.String   sql,pagesql;  
     java.sql.ResultSet   rs,pagers;
     Statement   statement=null;
     String   kmsdb= "jdbc:microsoft:sqlserver://127.0.0.1:1433;DatabaseName=DBName ";
     Class.forName( "com.microsoft.jdbc.sqlserver.SQLServerDriver ");
    conn   =   DriverManager.getConnection(kmsdb,   "user ",   "pwd ");
    
     pagesql   =   "SELECT   COUNT(*)   FROM Authors ";  
  
  //取总文章数  
  statement   =   conn.createStatement();
  pagers   =   statement.executeQuery(pagesql);  
     while(pagers.next())
   {
/*****************请看这里*******************/
   allCol   =   pagers.getInt(1);
   System.out.println(allCol);
     
      //如果去掉System.out.println(allCol);比如我输入第55页的时候(实际上根本没那么多页)   ,则会在控制台上打印出:
    //2007-6-12   12:54:34   org.apache.tomcat.util.http.Parameters   processParameters
//警告:   Parameters:   Invalid   chunk   ignored.  
 
/*****************以上是出问题的地方*******************/


  }
    
  //获得总页面数  
  allpage   =   (int)Math.ceil((allCol   +   ipage-1)   /   ipage);  
  //判断参数pages是否空  
  if   (request.getParameter( "pages ")==null)   {  
  pages=1;  
  }   else   {  
  pages   =   new   Integer(request.getParameter( "pages ")).intValue();  
  System.out.println(pages);
  }  
  //判断当前页  
  if(pages   >   allpage   ||   pages   ==   0)
  {cpage   =   1;}
  else
