私はj2meポリッシュの疑いがあった。私はEclipse IDEを使用しています。 J2MEの私のブルートゥース・アプリケーションの2つのJavaファイルがある上BluetoothHandler.javaj2meポリッシュを解決するのに役立ちます - ブルートゥースの問題

：次は私のJ2MEのファイルですモバイルにデプロイして実行すると正常に動作します（検出されたデバイスのアドレスと名前が表示されます）。
しかし、私は新しいJ2MEポリッシュプロジェクトを作成します.2つのJavaファイルをj2meポリッシュプロジェクトのソースディレクトリにコピーします。また、右クリックしてビルドパスに "\ J2ME-Polish \ import \ btapi.jar"を追加しますプロジェクトのプロパティ - > javaビルドパスを選択し、タブライブラリを選択してbtapi.jarを追加します。
次のエラーが
エラーarisedさsimulaotr.thenそれから私はwirlessツールキットと日食にJ2MEポリッシュアプリケーションを実行します。
