jsp连接access数据库
我已经建立了用access建立了图书管理系统的数据库,并建立了图书明细表.也弄了数据源.执行别的jsp的文件都成功，但唯独连接数据库的都没用。请各位帮帮我

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

<p align= "center "> 图书管理系统图书明细表中记录如下 </p>
<table width= "640 " border= "1 " align= "center " bordercolor= "#7188e0 ">
<tr bgcolor= "d1d1ff ">
<Td width= "80 "> 图书编号 </th>
<th width= "300 "> 图书名称 </th>
<th width= "200 "> 出版社 </th>
<th width= "200 "> 定价 </th>
<th width= "200 "> 日期 </th>
</tr> <%
while(rs.next())
{%>
<tr bgcolor= "#f8f8f8 ">
<td> <%= rs.getString(1) %> </td>
<td> <%= rs.getString(2) %> </td>
<td> <%= rs.getString(3) %> </td>
<td bgcolor= "#f6f6f8 "> <%= rs.getString(4) %> </td>
<td> <%= rs.getString(5) %> </td>
</tr>
<%
}
rs.close();
stmt.close();
con.close();
%>
</table>
<p align= "center "> <br>
如果能看到表格中的数据，说明连接数据库成功！ </p>

执行后显示

[解决办法]
数据源没设置好
[解决办法]
Class.forName( "sun.jdbc.odbc.JdbcOdbcDriver ").newInstance();
String s = "jdbc:odbc:Driver={Microsoft Access Driver (*.mdb)};DBQ=d:/jsp/oa/database/oa_database.mdb ";
[解决办法]
try{
Class.forName( "sun.jdbc.odbc.JdbcOdbcDriver ");
}
catch(ClassNotFoundException e){
System.out.print(e);
}
try{
String url = "jdbc:odbc:driver={Microsoft Access Driver (*.mdb)};DBQ=C://Inetpub//wwwroot//Yeyinews//news.mdb ";
Connection conn = DriverManager.getConnection(url);
Statement stmt = conn.createStatement();
.........
}
catch(Xeception e){
}
上面的代码实际使用过，应该没有什么问题
[解决办法]
那个连接数据库还可以全用代码的哈
String str=path( "/ ");
String realpath=repace( "\\ ", "/ ");
String url = "jdbc:odbc:driver={Microsoft Access Driver (*.mdb)};DBQ=realpath "+ "**.mdb ";
Connection conn = DriverManager.getConnection(url);
Statement stmt = conn.createStatement();
[解决办法]
jdbc:odbc:jspdata有问题,数据源连接问题
[解决办法]
你要先创建一个ODBC数据源
[解决办法]
注意建数据源时应选择“系统数据源”，即“系统DSN”。
[解决办法]
这段程序应该没问题，估计是ODBC设置问题 。。。
注意看看都是半角么？该不会用中文的输入的符号吧
[解决办法]
看一下你的tomcat 的webapps\ 是否加入了你的jsp项目吧.
