                catch(ClassNotFoundException cnfEx) 
                {
                    System.out.println("* Unable to load driver! *");
                    System.exit(1);
                }
                catch(SQLException sqlEx) 
                {
                    System.out.println("* Cannot connect to database! *");
                   System.out.println(sqlEx.getMessage());
                    System.exit(1);
                }

            try 
            {
                link.close();
                System.out.println("Disconnected to database");
            }
                catch(SQLException sqlEx) 
                {
                    System.out.println("* Unable to disconnect! *");
                    System.exit(1);
                }
         }
   }

错误:

error:

* Cannot connect to database! *
[Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified

推荐答案

问题可能出在连接字符串或配置上.

查看是否有这些帮助:
ODBC驱动程序管理器–找不到数据源名称，也未指定默认驱动程序 [ [Microsoft] [ODBC驱动程序管理器]找不到数据源名称，未指定默认驱动程序 [

The issue can be with connection string or the configuration.

See if these help:
ODBC Driver Manager – Data source name not found and no default driver specified[^]
[Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified[^]
