爲什麼我會得到「未找到數據源名稱並且沒有指定默認驅動程序」？

Question

從Java，我想連接到服務器中的.ACCDB文件（DSN較少），我不斷收到錯誤。我搜索了幾個小時，找不到任何東西。請幫忙！

String sURL = "jdbc:odbc:Driver={Microsoft Access Driver (*.mdb, *.accdb)};DBQ=DBQ=C:/test/theDB.accdb;READONLY=true;"; 

     try { 
      Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");   
      log.debug("url: "+sURL);     

      // create connection to database using connection string 
      dbCon = DriverManager.getConnection(sURL); 

} 
catch(SQLException e) { 
      //retry 
      try{dbCon = DriverManager.getConnection(sURL);} 
      catch(SQLException ex){ 
       // Now, it is real failing. Throw exception 
       log.error("Fail second time",ex); 
       throw new SQLException(e.getMessage()); 
      } 
     } catch (ClassNotFoundException e) { 
      log.error(e.getMessage()); 
      throw new SQLException(e.getMessage()); 
     } 
     return dbCon; 

這裏是例外，我得到：

java.sql.SQLException: [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified at sun.jdbc.odbc.JdbcOdbc.createSQLException(Unknown Source) [na:1.7.0_10] at sun.jdbc.odbc.JdbcOdbc.standardError(Unknown Source) [na:1.7.0_10] at sun.jdbc.odbc.JdbcOdbc.SQLDriverConnect(Unknown Source) [na:1.7.0_10] at sun.jdbc.odbc.JdbcOdbcConnection.initialize(Unknown Source) [na:1.7.0_10] at sun.jdbc.odbc.JdbcOdbcDriver.connect(Unknown Source) [na:1.7.0_10] at java.sql.DriverManager.getConnection(Unknown Source) [na:1.7.0_10] at java.sql.DriverManager.getCon...

DBQ=DBQ=C: ...可能會引起問題。一個DBQ=就足夠了。
