我想实现JSP一个页面内传递参数，页面分为上部分与下部分；
下部分是A,B,C，D实物的小图，比如，当点A时，上部分会从ACCESS数据库中调用出A的详细信息（A,B,C小图也是由ACCESS中调用出来的,运行决报错，请多多指教。。程序如下：
<%@ page contentType="text/html; charset=gb2312" language="java" import="java.sql.*" errorPage="" %>
<html xmlns="http://www.w3.org/1999/xhtml">

Class.forName("sun.jdbc.odbc.JdbcOdbcDriver"); //载入驱动程序类别
Connection con = DriverManager.getConnection("jdbc:odbc:jspdata"); //建立数据库链接,jspdata为ODBC数据源名称
//建立Statement对象
Statement stmt = con.createStatement(ResultSet.TYPE_SCROLL_INSENSITIVE,
ResultSet.CONCUR_READ_ONLY);
ResultSet rs = stmt.executeQuery("select * from watch"); //建立ResultSet(结果集)对象，并执行SQL语句

要是varchar , sql语句是("select * from watch where wid ='"+picId+"'");
要是int , 把 picId 转成int类行
<%
int picId =0;
if(request.Parameter(nid)!=null){
picId = request.Parameter(nid);
}
ResultSet tt = stmt.executeQuery("select * from table where id = " +picId); 还不行，

你的 "wid="是数据库里是int 还是varchar,
要是varchar , sql语句是("select * from watch where wid ='"+picId+"'");
要是int , ---
单引号加了吗?
另:
symbol : variable nid
nid未定义
Objece object
这里应该是Object
Object object = connection.executeQuery("select * from watch where id = picId");
应该改为
Object object = stmt.executeQuery("select * from watch where id = picId");
又或者你在输入代码时心里面在想着晚上该用什么招式和MM过招。
