一个很奇怪的跳页有关问题_Java Web开发

一个很奇怪的跳页问题
首先我写了一个搜索本地索引文件的JSP，用到lucene检索包里面的Hits类。searchindex.jsp如下：

Java code

<%@ page language="java" contentType="text/html; charset=gb2312"    pageEncoding="gb2312"%>    <%@page import="org.apache.lucene.search.*,ly.SearchIndex"%><!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"><html><head><meta http-equiv="Content-Type" content="text/html; charset=gb2312"><title>搜索结果</title><style type="text/css"><!--.STYLE1 {    font-family: "仿宋_GB2312";    font-size: xx-large;    font-color: #666666}--></style></head><body><p class="STYLE1">&#25628;&#32034;&#32467;&#26524;&#65306; </p><hr><% String keyword = new String(request.getParameter("searchquery").getBytes("ISO-8859-1"),"gb2312"); Hits hits = (new SearchIndex()).search(keyword); int length = hits.length(); int currentPage,recordPerPage=13;  if (request.getParameter("currentPage") == null)     currentPage = 1; else     currentPage = Integer.valueOf(request.getParameter("currentPage"));for (int i = (currentPage-1)*recordPerPage;i < length && i < currentPage*recordPerPage;i++){    out.println("<a href=\""+hits.doc(i).get("URL")+"\">"+hits.doc(i).get("title")+i+"</a><br>");        String bodyContain = hits.doc(i).get("body").substring(0,1023);    String tempkeyword = null;    if (keyword.charAt(0) >= 65 && keyword.charAt(0) <= 90)    {        tempkeyword = keyword.replace(keyword.charAt(0),(char)(keyword.charAt(0)+32));        bodyContain = bodyContain.replaceAll(tempkeyword , "<font color=#E50060>" + tempkeyword + "</font>");    }    else if (keyword.charAt(0) >= 97 && keyword.charAt(0) <= 122)    {        tempkeyword = keyword.replace(keyword.charAt(0),(char)(keyword.charAt(0)-32));        bodyContain = bodyContain.replaceAll(tempkeyword , "<font color=#E50060>" + tempkeyword + "</font>");    }    bodyContain = bodyContain.replaceAll(keyword , "<font color=#E50060>" + keyword + "</font>");    out.println(i+"<br>");    out.println(bodyContain);    out.println(i+"<br>");    out.println("<br/><br/>");}out.println("<br/>");out.println("there is " + length + " result matched");%><hr>共有<%=length%>个记录&nbsp;<%if (length%recordPerPage == 0) out.println(length/recordPerPage);    else out.println(length/recordPerPage + 1);%>页&nbsp;每页显示<%=recordPerPage%>个记录&nbsp;&nbsp;<br/><%if(currentPage == 1){ out.print(" 首页 上一页");   }else{  %>       <a href="searchindex.jsp?currentPage=<%=1%>">首页</a>    <a href="searchindex.jsp?currentPage=<%=currentPage-1%>">上一页</a>    <%}%><%if(currentPage == length){ out.print("下一页 尾页");   }else{  %>       <A HREF="searchindex.jsp?currentPage=<%=currentPage+1%>">下一页</A>    <A HREF="searchindex.jsp?currentPage=<%=length%>">尾页</A>    <%}%></body></html>

SearchIndex是一个类，我用来检索本地索引文件用的。Hits是搜索到的结果，用doc(i)取出来，实际相当一个记录。
这段代码会出现两个问题：一，先请看for语句下的

Java code

out.println(i+"<br>");    out.println(bodyContain);    out.println(i+"<br>");
