當執行此操作時,我的程序第二次執行此循環時遇到致命錯誤,循環執行此語句Statement stmt = conn.createStatement();。這是什麼造成的?不允許通過方法傳遞連接嗎?該程序通過這個循環運行:由連接方法造成的JRE檢測到致命錯誤

Connection conn = open_connection(); 

for(int aa = 0;aa<symbols.length;aa++){ 
    String[][] dub_array = parse(symbols[aa]); 
    autowave(dub_array,19,14,symbols[aa],conn); 
} 

OPEN_CONNECTION看起來是這樣的:

public static Connection open_connection() throws Exception{ 

    Class.forName("sun.jdbc.odbc.JdbcOdbcDriver"); 
    String sDBQ = "C:/Documents and Settings/mike/Desktop/stock/data/AW.mdb"; 

    String database = "jdbc:odbc:Driver={Microsoft Access Driver (*.mdb)};DBQ=" + sDBQ + ";DriverID=22;READONLY=false"; 
    Connection conn = DriverManager.getConnection(database ,"",""); 

    return conn; 
} 

以下是錯誤:

My program is encountering a fatal error when executing this like a second time a loop executes this statement Statement stmt = conn.createStatement(); autowave(dub_array,19,14,symbols[aa],conn); Try to create only one statement object before loop, then use it in loop. JdbcOdbcDriver with MS Access is lame and will meet unexpected issue sometimes.
