  我的一个详细的jsp分页程序!(oracle+jsp+Apache
  一 前提
  希望最新的纪录在开头给你的表建立查询:
  表:mytable
  查询:create or replace view as mytable_view from mytable order by id desc 其中,最好使用序列号create sequence mytable_sequence 来自动增加你的纪录id号

  二 源程序
  <%String sConn="你的连接"
  Class.forName("oracle.jdbc.driver.OracleDriver");
  Connection conn=DriverManager.getConnection(sConn,"你的用户名","密码");
  Statement stmt=conn.createStatement(ResultSet.TYPE_SCROLL_SENSITIVE,ResultSet.CONCUR_UPDATABLE);
  Statement stmtcount=conn.createStatement(ResultSet.TYPE_SCROLL_SENSITIVE,ResultSet.CONCUR_UPDATABLE);

  ResultSet rs=stmt.executeQuery("select * from mytable_view");
  String sqlcount="select count(*) from mytable_view";
  ResultSet rscount=stmtcount.executeQuery(sqlcount);

  int pageSize=你的每页显示纪录数;
  int rowCount=0; //总的记录数
  while (rscount
  int pageCount; //总的页数
  int currPage; //当前页数
  String strPage;
  strPage=request.getParameter("page");
  if (strPage==null){
  currPage=1;
  }
  else{
  currPage=Integer.parseInt(strPage);
  if (currPage<1) currPage=1;
  }
  pageCount=(rowCount+pageSize-1)/pageSize;
  if (currPage>pageCount) currPage=pageCount;

  int thepage=(currPage-1)*pageSize;
  int n=0;
  rs.absolute(thepage+1);
  while (n<(pageSize)&&!rs
  %>
  <%rs.close();
  rscount.close();
  stmt.close();
  stmtcount.close();
  conn.close();
  %>

  //下面是 第几页等
  <form name="sinfo" method="post" action="sbinfo_index.jsp?condition=<%=condition%>&type=<%=type%>" onSubmit="return testform(this)">
  第<%=currPage%>页 共<%=pageCount%>页 共<%=rowCount%>条
  <%if(currPage>1){%><a href="sbinfo_index.jsp?condition=<%=condition%>&type=<%=type%>">首页</a><%}%>
  <%if(currPage>1){%><a href="sbinfo_index.jsp?page=<%=currPage-1%>&condition=<%=condition%>&type=<%=type%>">上一页</a><%}%>
  <%if(currPage<pageCount){%><a href="sbinfo_index.jsp?page=<%=currPage+1%>&condition=<%=condition%>&type=<%=type%>">下一页</a><%}%>
  <%if(pageCount>1){%><a href="sbinfo_index.jsp?page=<%=pageCount%>&condition=<%=condition%>&type=<%=type%>">尾页</a><%}%>
  跳到<input type="text" name="page" size="4" style="font-size:9px">页
  <input type="submit" name="submit" size="4" value="GO" style="font-size:9px">
  </form>
