刚刚接触JSP。写了个注册的东西。
在注册表单内容提交到reg_action.jsp处理页面时，报错如下：
org.apache.jasper.JasperException: Unable to compile class for JSP

An error occurred at line: 11 in the jsp file: /reg_action.jsp
Generated servlet error:
Syntax error on token "(", . expected

An error occurred at line: 11 in the jsp file: /reg_action.jsp

--------------------------------------
其中，reg_action.jsp页面代码如下（第11行是<%)：

解决了．谢谢大家～
一个是lengthcheck 有问题，同上楼所说两个问题．
另一个是temp.indexOf(temp)!=-1报错，检查中．

JSP里写方法，不好的习惯哦

还有LengthCheck(String str,int MinLength,int MaxLength)方法的返回值也有问题
是不是boolean类型呢？

LZ 你的LengthCheck()方法这样定义不对，应该在开头这样
<%!
public LengthCheck(String str,int MinLength,int MaxLength)
{
return((str.length>=MinLength)&&(str.length<=MaxLength));
}
%>
而不能直接插到jsplet里面！
