ファイルアップロードについて

画像をアップロードしたかったため、調査を開始。

とりあえず、リファレンスを見なければ始まらないので以下を参照しながら実装していきます。
Teeda - JSF meets DI and AOP -


そして、実装したHTMLとPageクラスは以下の通り。
HTML

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xmlns:te="http://www.seasar.org/teeda/extension" xml:lang="ja" lang="ja">
  <head>
    <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
    <title>ファイルアップロード</title>
  </head>
  <body>
    <form id="Form">
        <input type="file" id="uploadFile" />
        <input type="button" id="doUplode" value="アップロード" />
        <span id="result"></span>
    </form>
  </body>
</html>

Pageクラス

import java.io.File;

import org.seasar.teeda.extension.util.UploadedFile;

public class FileUplodePage {

	public UploadedFile uploadFile;
	public String result;

	public Class doUplode() {
		File filePass = new File("C:\\Work", uploadFile.getName());
		try {
			uploadFile.write(filePass);
			
			result = "アップロード完了";
		} catch (Exception e) {
			// TODO 自動生成された catch ブロック
			e.printStackTrace();
		}
		return null;
	}
	initialize()、prerender()省略
}


そして、いざやってみると以下のエラーが出ました。

Seasarのメーリングリストを見て似たような現象を見ましたが、
Doltengで作ったプロジェクトですし「tomahawk-1.1.1.jar」使ってないしなぁ・・・
と泥沼化している感じです。


もう少し調べてわからなったら、別のところを実装しようっと・・・
