JSP连接SQL2000的问题
系统是win2003的，JDK1.5，数据库是sqlserver2000，tomcat5.5
运行的时候报错如下：
The server encountered an internal error () that prevented it from fulfilling this request.
exception
javax.servlet.ServletException: [Microsoft][ODBC 驱动程序管理器] 未发现数据源名称并且未指定默认驱动程序

数据源名称没问题啊，我用的是JDBC-ODBC桥接，是否还需要下载JDBC驱动呢？还望各位高手指教！
程序主要部分如下：
Connection con=DriverManager.getConnection( "jdbc:odbc:sim ", " ", " ");
try
{
Statement sql=con.createStatement();
}
catch(SQLException e)
{}
//Connection con;
Statement sql;
ResultSet rs;
try
{
Class.forName( "sun.jdbc.odbc.JdbcOdbcDriver ");
}
catch(ClassNotFoundException e)
{}
try
{
con=DriverManager.getConnection( "jdbc:odbc:sim ", " ", " "); //得到与数据库的连接
sql=con.createStatement();
rs=sql.executeQuery( "SELECT * FROM sim_table ");
out.print( " <table border> ");
out.print( " <tr> ");
out.print( " <th width=100> "+ "卡号 ");
out.print( " <th width=100> "+ "套餐种类 ");
out.print( " <th width=100> "+ "办卡时间 ");
out.print( " <th width=100> "+ "余额 ");
out.print( " <th width=100> "+ "归属地 ");
out.print( " </tr> ");
while(rs.next())
{
out.print( " <tr> ");
out.print( " <td> "+rs.getString( "sim_NUM ")+ " </td> ");
out.print( " <td> "+rs.getString( "type ")+ " </td> ");
out.print( " <td> "+rs.getString( "time ")+ " </td> ");
out.print( " <td> "+rs.getString( "balance ")+ " </td> ");
out.print( " <td> "+rs.getString( "locus ")+ " </td> ");
out.print( " </tr> ");
}
out.print( " </table> ");
con.close();
}
catch(SQLException e1)
{}
[解决办法]
是不是没把驱动放到相应目录？
[解决办法]
到微软公司网站上下载JDBC驱动程序包吧！然后放到TOMCAT的/command/lib目录下，或者放到应用网站的WEB-INF/lib下中！同时还要把这个JDBC驱动程序加入classpath环境变量中去,更多关于JSP开发方面的资料，万春IT技术开网（http://wcp.fh668.com）不错！不妨上去看一下！
[解决办法]
直接用Class.forName( "com.microsoft.jdbc.sqlserver.SQLServerDriver ").newInstance();
这个驱动吧，用JDBC-ODBC桥接，太烦，而且实际数据也中转了好几次，下个jdbc.sqlserver驱动吧
[解决办法]
使用桥接要配置数据源吧，没用过，直接用JDBC效率高
