すべて、Class.forName("com.mysql.jdbc.Driver")を使用してドライバクラスをロードしようとしたとき、私はcom.mysql.jdbc.Driver例外を取得していますは、Eclipse RCP IDE

でMySQLを接続できません。カスタムEclipseプラグインを作成し、カスタムEclipseプラグインでデータベースにアクセスしたいと思っています。私は2つのオプションは、両方のは明らかに失敗し、次の試してみました


1>
2 Eclipseプラグインのビルド・パスにmysqlの接続のJARファイルを追加する>ライブラリとしてコネクタのJARファイルを追加し、プラグインの実行時のクラスパス

に追加します

誰も私にこれを助けてくれますか?ここで

はログです:

"com.mysql.jdbc.Driver例外"は何も意味しません。実際の例外とは何ですか?投稿を編集し、COMPLETEスタックトレースを追加してください。 –

私はハウツーためhttp://wiki.eclipse.org/Create_and_Export_MySQL_JDBC_driver_bundleを参照して、MySQLドライバ用に独自のOSGiバンドルを作成することをお勧めします。その後、バンドルのplugin.xmlに作成されたmysql-bundleへの依存関係を設定する必要があります。

さらに、DriverManagerではなくDataSourceの実装であるOSGi環境で使用してください。
