我正在编写一个使用SQLite的应用程序,在它运行的Netbeans中,但是当我生成一个.jar文件来使用我的应用程序时,它不起作用。我以为该应用程序将创建一个db文件(同一文件夹).jar文件。我在AlertMessage中看到的唯一错误是:ClassNotFound异常。
private void getConnection() throws ClassNotFoundException, SQLException {
Class.forName("org.sqlite.JDBC");
con = DriverManager.getConnection("jdbc:sqlite:Dados");
initialize();
}
编辑:
我将功能编辑为:
private void getConnection() {
try {
JOptionPane.showMessageDialog(null, "getConnection() 1");
Class.forName("org.sqlite.JDBC");
JOptionPane.showMessageDialog(null, "getConnection() 2");
con = DriverManager.getConnection("jdbc:sqlite:Dados.db");
JOptionPane.showMessageDialog(null, "getConnection() 3");
initialize();
} catch (Exception e) {
String s = "\nException: " + e.getClass().getName() + "\n";
for(int i = 0; i < e.getStackTrace().length; i++) {
s += e.getStackTrace()[i] + "\n";
}
JOptionPane.showMessageDialog(null, "Error 1: " + s);
}
}
仅限&#34; getConnection()1&#34;显示。所以错误似乎发生在:
Class.forName("org.sqlite.JDBC");
错误是:
