ここに投稿された回答に従っています。struts2-tiles-plugin を使用してタイル定義で動作する OGNL とワイルドカード?
答えがわかっている場合は、freemarker の使い方を教えていただければ幸いです。コードを機能させるために私の問題を解決すれば、私は答えを受け入れます。
全部同じだけど

結論
コードでテストしたようにGlassfishで使用すると正常に動作しますが、
多くのテストとチェックの後、問題は、上記の web.xml 構成で機能せず、エラーを生成する組み込みの tomcat7 インスタンスにあります。以下は、pom.xml
tomcat7:run を実行するとエラーが生成されるプラグインです。何が問題なのかわからない。
