Mule EE を使用して、次のプロジェクトがあります。

正しく動作します。ただし、使用する FTP コネクタを追加するとmoveToDirectory、Mule から次のようなNON-STOP のエラーが表示されます。ファイルは目的のディレクトリに移動されますが、Mule で同じエラーが無限に発生します。Mule の実行を停止しない限り、停止しません。Mule はフローを続行しません (DB への挿入とメールの送信)。

mytest.csv の内容は次のようになります: (DB は同じ列で、シリアル番号は主キーです)
date|serialnumber|gender|fullname|email|mobilenumber|address
03-07-2014|546565|m|your name|my@mail.com|219239|my address
と を使ってみまし#[message.inboundProperties.originalFilename]たoutputPattern="#[header:originalFilename]"。おそらくそれらは間違っているかもしれませんが、とにかく、Mule は変更なしで同じエラーを表示し続けます!
ポイントは、ファイルを FTP からローカル PC に移動し、DB に挿入してから電子メールで送信することです。（両方の道路を一緒に）。どんな助けでも大歓迎です！
