Question

执行此程序时，我的程序遇到致命错误，就像第二次循环执行此语句Statement stmt = conn.createStatement();一样。是什么造成的？不允许通过方法传递连接吗？该程序贯穿整个循环：

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看起来像这样：

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;
}

这是错误：

我的程序在第二次执行时会遇到致命错误 loop执行此语句Statement stmt = conn.createStatement（）; 自动波（dub_array，19,14，符号[AA]，康涅狄格州）; 尝试在循环之前只创建一个语句对象，然后在循环中使用它。带有MS Access的JdbcOdbcDriver很蹩脚，有时会遇到意外问题。

连接方法导致JRE检测到致命错误
