Subject [jira] [Commented] (WW-4362) ExecAndWait Interceptor with FileUploadInterceptor incompatibility
Date Tue, 16 Sep 2014 07:03:34 GMT

    [ https://issues.apache.org/jira/browse/WW-4362?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14135071#comment-14135071

Lukasz Lenart commented on WW-4362:
-----------------------------------

I think you should implement your own version of {{MultiPartRequest}} or extend one of existing
and reimplement {{cleanUp}} method to do what you need. I don't have an idea how to solve
it in nicer way without creating a dependency between {{FileUploadInterceptor}} and {{ExecuteAndWaitInterceptor}}

> When using execAndWait interceptor with FileUpload interceptor, the uploaded file is
removed before processing.
> *Steps to reproduce :*
> On a sample project, add a simple action which expects a file and a struts.xml of the
form :
> {code:xml}
> <!DOCTYPE struts PUBLIC
>     "-//Apache Software Foundation//DTD Struts Configuration 2.3//EN"
>     "http://struts.apache.org/dtds/struts-2.3.dtd  ">
> <struts>
> 	<constant name="struts.enable.DynamicMethodInvocation" value="false" />
> 	<constant name="struts.devMode" value="true" />
> 	<constant name="struts.action.extension" value="," />
> 	<package name="accueil" namespace="/" extends="struts-default">
>    <action name="">
>          <result name="success">WEB-INF/jsp/accueil.jsp</result>
>       </action>
> 		<action name="accueil">
> 			<result name="success">WEB-INF/jsp/accueil.jsp</result>
> 		</action>
> 		<action name="simple" class="net.micedre.action.SimpleAction">
>          <interceptor-ref name="executeAndWaitStack" />
>      
> 			<result name="error">WEB-INF/jsp/accueil.jsp</result>
> 			<result name="success">WEB-INF/jsp/accueil.jsp</result>
>          <result name="wait">WEB-INF/jsp/wait.jsp</result>
> 		</action>
> 	</package>
> </struts>
> {code}
> In the case of the attached example, the uploaded file is deleted before any treatment
by SimpleAction on it.
> This is caused by the StrutsFilter which cleans up the request leading to a deletion
(in the case of jakarta file-upload) before the BackgroundProcessThread created by the execAndWait
interceptor runs (or during).
