初めて投稿させていただきます。
eclipse3.2でstruts1.3.8を使ってWebアプリケーションを学習しているのですが、
tomcatを起動し、ブラウザ画面にて 「HTTPステータス 500 -」 が表示され悩んでいます。やりたいことは、"hello.do"からHelloActionへ、findForward("hoge") で、jsp画面を表示させたいのですが。
以下、詳細です。

コンソールにて、ClassNotFoundException がでており、ActionClassがないと言っているのですが、Actionを継承して、execute()のオーバーライドは確認しています。
struts-configでも、記述にミスがないと思うのですが。
eclipseの設定なのでしょうか？ご教授、宜しくお願いします。

HelloAction.java が無いのでは？

コメントありがとうございます。
struts-config のアクションサーブレットを指定しているヵ所のパッケージの"java.…"のところを削除して、尚且つディレクトリのパッケージのjavaを削除して実行したら、解決しました。
何故だかはわかりません。
どこの、なんの設定なのかも検討もつきません。
できれば、ご教授を宜しくお願いします。

Tomcat にサーブレットのサンプルプログラムが付属していますよね？

何が違うのか比べてみてはいかがでしょう。
