我正在使用Struts 2.3.15.2。我写下了我的行动：
<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>
如果在网址中我称之为localhost:8080/myProject/ricerca.action有效。如果我调用localhost:8080/myProject/ricerca!input.action它会抛出我的：
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].

我不明白这是某些设置的问题还是其他问题。在旧版本的 struts 上它可以工作，但由于瓷砖不兼容问题，我不得不升级。
