奇怪的错误，下面的语句出现这种奇怪的异常！！！
String sql="select id from jicq where name=? and password=?";
PreparedStatement prepare3=c.prepareCall(sql);
prepare3.clearParameters();
//name="'"+name+"'";
//passwd="'"+passwd+"'";
prepare3.setString(1,name);
prepare3.setString(2,passwd);
System.out.println("#############"+sql);
try{
ResultSet r1=prepare3.executeQuery(sql);
System.out.println("测试语句");
while(r1.next()){
no=r1.getInt(1);
}
}
catch(Exception e2){
e2.printStackTrace();


}
System.out.println("no="+no);
out.println(no);
c.close();

异常输出：
#############select id from jicq where name=? and password=?

这个：prepare3.setString(1,name);
prepare3.setString(2,passwd);
就在PreparedStatement prepare3=c.prepareCall(sql);之前
