<%String str=request.getParameter("name");
if(str==null)

byte c[]=str.getBytes("ISO-8859-1");
str=new String(c);
String selectContent=request.getParameter("class");
byte b[]=selectContent.getBytes("ISO-8859-1");
selectContent=new String(b);
out.println("亲爱的"+str+"同学，您来自"+selectContent+",Welcome!");
%>
</body>
</html>
这段代码有两个问题，一个输入名字之后提交后显示不出来，一个是输出的中文任然乱码，希望高手能帮忙解决一下，谢谢。

<input type="text" name=“name”>这句name用了中文的双引号;
剩下的就是设置编码问题;
你我这样你就不用每次都byte b[]=selectContent.getBytes("ISO-8859-1")什么的了

你这样设置的是本页面处理，最好在<form>里传个隐藏表单用来判断是提交的页面，还是刚开始的页面;
