Question

我是JSP的新手。所以我想创建一个登录网站，但我坚持使用sql异常。 Annyone知道如何解决这个问题？我使用的所有程序都是32位，我已经将Ms Access数据库添加到我的用户数据源。

这是错误信息：

5: <%
6:  Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
7:  Connection con = DriverManager.getConnection("jdbc:odbc:Driver={Microsoft Access Driver (*.mdb, *.accdb)};DBQ="+application.getRealPath("WEB-INF/db.accdb"));
8:  Statement st = con.createStatement(1004,1008);
9: 
10: %>
