jdk1.4+tomcat4.1+Sql Server 2k
表中有个字段memo(备注型):用来保存输入的内容 
我输入的一段文字，有好几段，现在要显示它，显示出来就是一段，没有分段，请那位高手解决一下，谢谢！ 
String memo=rs.getString(3).replaceAll("
","vbcrlf"); 

出现下面错误：
type Exception report

root cause

String方法没有replaceAll（String,String）方法，我自己写了一个，你看看：
    /*
        ×Ö·û´®Ìæ»»
    */
    public static String stringreplace(String line,String oldString,String newString){
        if(line==null||oldString==null||newString==null){
            return "";
        }
        int i=0;
        int j=0;
         if((i=line.indexOf(oldString,i))>=0){
             char[] line2=line.toCharArray();
             char[] newString2=newString.toCharArray();
             StringBuffer buf=new StringBuffer(line2.length);
             int olength=oldString.length();
             buf.append(line2,0,i).append(newString2);
             i+=olength;
             j=i;
             while((i=line.indexOf(oldString,i))>0){
                buf.append(line2, j, i-j).append(newString2);
                i +=olength;
                j = i;
            }
            buf.append(line2, j, line2.length - j);
            return buf.toString();
        }
        return line;
    }
==========================
使用方法：
        source=stringreplace(source,"rn","
") ;
        source=stringreplace(source,"n","
") ;
