appengine struts 2.3.4.1 error (struts trying to reload server)

Question

I'm facing this problem on my struts 2.3.4.1 AppEngine 1.7.2 (GAE) project. It seems that struts is trying to reload the server and it's forbidden by appEngine.

I've googled this issue but only found struts2.1.8 version error fixing changing by struts2.1.6.

web.xml:

<web-app xmlns="http://java.sun.com/xml/ns/javaee" version="2.5">
<display-name>LifeMusic</display-name>

<filter>
  <filter-name>struts2</filter-name>
  <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
</filter>

<filter-mapping>
  <filter-name>struts2</filter-name>
   <url-pattern>*.action</url-pattern>
</filter-mapping>   

<welcome-file-list>
    <welcome-file>home.jsp</welcome-file>

Answer 1

Put this properties to false at struts.properties:

struts.configuration.xml.reload=false
struts.devMode = false
struts.i18n.reload=false

Answer 2

The given solution didn't work for me, instead I had to create a custom plugin that overrides the default FileManager and FileManagerFactory implementations: https://stackoverflow.com/a/20458563/313113
