求一个简单的jsp修改sql数据的例子 - Java / Web 开发

我用的是：
Connection conn= DriverManager.getConnection(url,user,password);  
String sql="updata zhuqiuling set xuanze1=? where name='zhuqiuling'";

PreparedStatement pstmt=conn.prepareStatement(sql);
 pstmt.clearParameters();
 pstmt.setString(1,choice);
 pstmt.executeUpdata();

可是一直调试不出来
小弟是初学者 希望大家帮帮我
先谢谢大家了

提示的错误是：
org.apache.jasper.JasperException: An exception occurred processing JSP page /shiti/xuanze1.jsp at line 30

27: PreparedStatement pstmt=conn.prepareStatement(sql);
28: pstmt.clearParameters();
29: pstmt.setString(1,choice);
30: pstmt.execute();
31:
