我的代码如下：<%@ page session="true" %>
<%@ page import="java.sql.* " %>
<jsp:useBean id="pool" scope="session" class="text.check"/>
<html>
<head>
<title>Book store</title>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312"></head>
<body bgcolor="#F4F5FF">
<font face="Times New Roman,Time" size="+3"> 网上书店 </font>
<hr><p>
<center>

<%
String name=request.getParameter("name");
String pwd=request.getParameter("password");
String sql="select *from customer_info where Name='"+name+"' and Passwd='"+pwd+"'";

pool.getUserId(name);
pool.getSQL(sql);
rs1=pool.buildlink();
if(rs1.next()){
String customerid=temp.toString();
session.putValue("loginSign","OK");
session.putValue("cID",customerid);
response.sendRedirect("list.jsp");
}
else
{
rs1.close();
session.putValue("login_message","用户名或密码错误");
%>
<jsp:forward page="register.jsp"/>
<%
}
}
//catch(Exception e)
{
//e.getMessage();
}
%>
</center>
</body>
</html>

出错信息：

Posted by: YuLimin Posted on: 2005-10-28 08:56 login_jsp.java:31: 'try' without 'catch' or 'finally' 打开D:\Tomcat\work\Catalina\localhost\myweb\org\apache\jsp\shop\login_jsp.java:31 看看，然后对应到login.jsp去查查你的try catch不对应
