私は使用してStruts 2.3.15.2います。私は自分の行動を書きました：
<action name="ricerca" class="com.emaborsa.doctracing.web.action.ricerca.RicercaUtentiAction" method="ricerca">
<result name="input" type="tiles">utente.ricerca.def</result>
<result name="success" type="tiles">utente.elenco.def</result>
</action>
URLで私が呼び出す場合、localhost:8080/myProject/ricerca.actionそれは機能します。私がそれを呼び出すlocalhost:8080/myProject/ricerca!input.actionと、私がスローされます:
2013-10-16 23:49:50,602 ERROR [org.apache.struts2.dispatcher.Dispatcher] [http-bio-8080-exec-8] Exception occurred during processing request: There is no Action mapped for namespace [/utente] and action name [ricerca!input] associated with context path [/myProject].

設定の問題なのか、それとも別の問題なのかわかりません。Struts の古いバージョンでは動作しますが、タイルとの非互換性の問題のためにアップグレードする必要がありました。
