在线, 即给100分,怎样处新闻内容页(段落形式),谢了

我的程序与测试如下:  
<%@page  import="java.sql.*"  contentType="text/html;charset=gb2312"%>  
<%@  page  language="java"    %>  
<%@  page  import="java.util.*"  %>  
<%@  page  import="java.io.*"  %>  
<%@  page  import="news.util.*"%>  
<html>  
<body>  
<jsp:useBean  id="mana1"  scope="page"  class="dataexec.dataexec"/>  
<%  
CodeFilter  codefilter=new  CodeFilter();  
String  id=null;  
String  content=null;  
int  myid=Integer.parseInt(request.getParameter("myid"));  
String  context=request.getParameter("context");  
context=new  String(context.getBytes("ISO8859_1"),"GB2312");  
context=codefilter.unHtml(context);                                                          //测试输出为中文  
String  sql1="insert  into  test  values('"+myid+"','"+context+"')";  
mana1.executeQuery(sql1);  
%>  
<%  
 String  sql="select  *  from  test";  
 ResultSet  rs=mana1.executeQuery(sql);  
 while(rs.next())  
{  
id=rs.getString(1);  
content=rs.getString(2);  
out.println(content);                                      //测试输出为中文  
content=codefilter.change(content);        //测试输出为数据码,如输入"斩草除根"则为&#26025;&#33609;&#38500;&#26681;    
}  
rs.close();  
%>  
</body>  
</html>    
 
 
转换用的javabean如下:  
 
package  news.util;  
import  java.io.*;  
 
public  class  CodeFilter{  
               public  CodeFilter()  {}  
               public  static  String  change(String  s)  {  
                           s  =  toHtml(s);  
                           return  s;  
               }  
 
           //特殊字符转为Html  
           public  static  String  toHtml(String  s)  {  
       s  =  Replace(s,"&","&amp;");  
       s  =  Replace(s,"<","&lt;");  
       s  =  Replace(s,">","&gt;");  
       s  =  Replace(s,"\t","        ");  
       s  =  Replace(s,"\r\n","\n");  
       s  =  Replace(s,"\n","<br>");  
       s  =  Replace(s,"    ","  &nbsp;");  
       s  =  Replace(s,"'","&#39;");  
       s  =  Replace(s,"\\","&#92;");  
       return  s;  
       }  
           //逆  
       public  static  String  unHtml(String  s){              
           s  =  Replace(s,"<br>","\n");  
           s  =  Replace(s,"&nbsp;","  ");  
           return  s;  
               }  
   
   //Replace  
     public  static  String  Replace(String  source,String  oldString,String  newString)  {  
       if(source  ==  null)  return  null;  
       StringBuffer  output  =  new  StringBuffer();  
       int  lengOfsource  =  source.length();  
       int  lengOfold  =  oldString.length();  
       int  posStart  =  0;  
       int  pos;  
       while((pos  =  source.indexOf(oldString,posStart))  >=  0)  {  
           output.append(source.substring(posStart,pos));  
           output.append(newString);  
           posStart  =  pos  +  lengOfold;  
       }  
       if(posStart  <  lengOfsource)  {  
           output.append(source.substring(posStart));  
       }  
       return  output.toString();  
   }
