-----------------------------------
Summary: ExecAndWait Interceptor with FileUploadInterceptor
incompatibility
Key: WW-4362
URL: https://issues.apache.org/jira/browse/WW-4362
Project: Struts 2
Issue Type: Bug
Components: Core Interceptors
Affects Versions: 2.3.16.3
Reporter: Cédric Couralet
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).
