catch(java.io.UnsupportedEncodingException e){

String trans(Object chi){
return trans(chi.toString());

调用时
String aa=this.trans(request.getParameter("tom"));
用的这个代码,请问为什么要存在两个文件中,我将这东西存在一个文件中就出错误!!!xtaotao(淘淘) ( ) 信誉:100 2006-3-31 19:58:29 得分: 5

我在开个帖子给你加分!!!
如果不存在检验request.getParameter的返回值是否为空,就会出现错误!!!!!
但这是为什么??????
