MySQL データベースを使用する GWT プロジェクトで JBPM を使用したいのですが、作成しようとすると次のエラーが発生しますEntityManagerFactory。私は何を間違っていますか？

この例外は、既に実行中の bitronix インスタンスがあることを意味します (ファイルを使用してロックを取得しています)。これは、正しくシャットダウンされなかった以前の実行の結果である可能性があります。たとえば、同じ例を Eclipse で複数回実行すると、それぞれが bitronix トランザクション マネージャーをインスタンス化しようとします。通常、Eclipse で実行中の他の Java プロセスを閉じるだけで、この問題は解決します。
