如何解决JSP里文章显示格式问题

文章分段的代码
int int2 = comment.length();
            StringBuffer StringBuffer3 = new StringBuffer();
            int int4;            for( int4 = 0; int4 < int2; ++int4 )
            {
                char char5 = comment.charAt( int4 );                switch( char5 )
                {
                    case 62:
                        StringBuffer3.append( "&gt;" );
                        break;
                    case 60:
                        StringBuffer3.append( "&lt;" );
                        break;
                    case 38:
                        StringBuffer3.append( "&amp;" );
                        break;
                    case 32:
                        StringBuffer3.append( "&nbsp;" );
                        break;
                    case 10:
                        StringBuffer3.append( "<BR>" );
                        break;
                    default:
                        StringBuffer3.append( char5 );
                        break;
                    case 13:
                        break;
                        
                        
                }
             }
  comment=StringBuffer3.toString();

  1.   

    用javascript控制就可以进去的时候，转化一下特殊标记，出来的时候反转化
      

  2.   

    我的内容字段为text行的
    应该怎么修改上面代码？
    不好意思，我刚学JSP
    An error occurred at line: 19 in the jsp file: /news/show.jspGenerated servlet error:
        [javac] Compiling 1 source fileC:\hongdun\work\Catalina\localhost\_\org\apache\jsp\news\show_jsp.java:65: cannot resolve symbol
    symbol  : variable nr  
    location: class org.apache.jsp.news.show_jsp
    int int2 = nr.length();
               ^An error occurred at line: 19 in the jsp file: /news/show.jspGenerated servlet error:
    C:\hongdun\work\Catalina\localhost\_\org\apache\jsp\news\show_jsp.java:71: cannot resolve symbol
    symbol  : variable nr

                    char char5 = nr.charAt( int4 );
      

  3.   

    应该是
    String nr=request.getParameter("text");
    再
    int int2 = nr.length();
      

  4.   


    Generated servlet error:
        [javac] Compiling 1 source fileC:\hongdun\work\Catalina\localhost\_\org\apache\jsp\news\show_jsp.java:191: nr is already defined in _jspService(javax.servlet.http.HttpServletRequest,javax.servlet.http.HttpServletResponse)
    String nr = rs.getString("nr");
                   ^
      

  5.   


    nr is already defined 
    它说nr这个变量在之前已经定义了
