scala播放框架文件上傳錯誤

我正在使用this教程來上傳我的play framework應用程序中的文件。我使用的是完全相同的代碼，但出現以下錯誤。scala播放框架文件上傳錯誤

[IOException: Path(/Users/hrishikeshparanjape/Desktop) exists but replace parameter is false]

以下是我的代碼：

def upload = Action(parse.multipartFormData) { request => 
     request.body.file("picture").map { picture => 
      import java.io.File 
      val filename = picture.filename 
      val contentType = picture.contentType 
      picture.ref.moveTo(new File("/Users/hrishikeshparanjape/Desktop/")) 
      Ok("File uploaded") 
     }.getOrElse { 
      Redirect(routes.Application.index).flashing(
        "error" -> "Missing file" 
        ) 
     } 
    }

我堅持在這裏，請幫助。

編輯： 這裏是我完整的堆棧跟蹤：

看起來你需要爲moveTo

picture.ref.moveTo(new File(
    "/Users/hrishikeshparanjape/Desktop/" + picture.filename))

該死指定完整的文件名。我很愚蠢。謝謝。（我試圖寫入我的桌面目錄（這是一個文件）） – riship89 2012-08-05 07:24:48
