嗨,我有以下代码连接到Windows 7操作系统上的MS Access数据库.我已将数据源快捷方式更改为指向64位odbc然后32位.但仍然得到错误

java.sql.SQLException: [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified
    at sun.jdbc.odbc.JdbcOdbc.createSQLException(JdbcOdbc.java:6956)
    at sun.jdbc.odbc.JdbcOdbc.standardError(JdbcOdbc.java:7113)
    at sun.jdbc.odbc.JdbcOdbc.SQLDriverConnect(JdbcOdbc.java:3072)
    at sun.jdbc.odbc.JdbcOdbcConnection.initialize(JdbcOdbcConnection.java:323)
    at sun.jdbc.odbc.JdbcOdbcDriver.connect(JdbcOdbcDriver.java:174)
    at java.sql.DriverManager.getConnection(DriverManager.java:579)
    at java.sql.DriverManager.getConnection(DriverManager.java:221)
    at TestDBConnection.main(TestDBConnection.java:21)

我的代码是:

import java.sql.Connection;
import java.sql.DriverManager;

public class TestDBConnection {

    public static void main(String[] args) {
        // TODO Auto-generated method stub
        try
        {
            System.out.println("filename");
            Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
            String database = 
                      "jdbc:odbc:DRIVER={Microsoft Access Driver (*.mdb)};DBQ=C:\\Test\\Tests.mdb";
            Connection conn = DriverManager.getConnection(database, "", "");
        } catch(Exception ex) {
            ex.printStackTrace();
        }
    }

}

我怎么有SQL Workbench工具,我可以通过它连接到它而不是通过java代码. …
