连接到MS Access数据库时出错

我在Access中有一个数据库。当我尝试使用库UCanAccess连接到它时：

Class.forName("net.ucanaccess.jdbc.UcanaccessDriver");
String url = "jdbc:ucanaccess://" + fileSrc;
conn = DriverManager.getConnection(url, user, password);
s = conn.createStatement();
ResultSet rs = s.executeQuery("SELECT * FROM patients");

连接时获取：

conn = DriverManager.getConnection(url, user, password);

此类错误：

如果我只导出所需的表并连接到它，则没有错误。但我需要使用完整的数据库。

EDITED

我删除了对DB中没有现有文件的引用，但错误仍然存​​在：
