请问这个要怎么解决，我想把默认值设为前一天日期
<%
SimpleDateFormat f=new SimpleDateFormat("yyyyMMdd");
String curdate=f.format(new Date());
%>

<input type="text" name="RQ" style="width:130" value="<%curdate %>">


这样写报错了。

org.apache.jasper.JasperException: Unable to compile class for JSP

An error occurred at line: 23 in the jsp file: /h1-g-new.jsp

要怎么解决。谢谢
[解决办法]

Calendar   c   =   Calendar.getInstance();    
c.add(Calendar.DAY_OF_MONTH, -1);   
string predate = f.format(c.getTime());

SimpleDateFormat f=new SimpleDateFormat("yyyyMMdd");
    Calendar c=Calendar.getInstance();    
    c.add(Calendar.DAY_OF_MONTH, -1);   
    String curdate = f.format(c.getTime());
//<%=curdate %>
