연결 메서드로 인해 JRE에서 치명적인 오류가 감지되었습니다.

Question

두 번째 루프에서이 문을 실행하면 내 프로그램에서 치명적인 오류가 발생합니다. Statement stmt = conn.createStatement();. 이 원인은 무엇입니까? 메서드를 통해 연결을 전달할 수 있습니까? 이 프로그램은이 루프를 통해 실행 : 여기

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; 
} 

를 오류입니다 :

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_connection은 다음과 같습니다

Answer 1

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.
