私は過去2日間ほどこの問題を解決しようとしていましたが、私は壁に当たっています。CommonsFileUpload - タイプDiskFileItemFactoryのparseRequest（HttpServletRequest）メソッドが未定義です
type: Exception report
message: Servlet execution threw an exception
description: The server encountered an internal error that prevented it from fulfilling this request.
exception:

java.lang.Error: Unresolved compilation problems:
Type mismatch: cannot convert from ServletFileUpload to List<FileItem>

私の（私は、Javaサーブレットによってアルファベット順に複数のファイルをアップロードしようとしているが、私は次のエラーを取得しています
result.jsp）code

ここで何をすればいいですか？
