InputFile, usesUpload and excel export on Glassfish

Question

Hello,
I am working in an ADF application which is deployed on a Glassfish server. I use jdeveloper 11.1.2.3.0.
I have problems with two components : the af:inputFile and the af:exportCollectionActionListener.
Cause of af:inputFile I had to change the usesUpload property to true.
[code]<af:form id="f1" usesUpload="true">[/code]
In Glassfish, if usesUpload property is true, the af:inputFile component have a strange behavior where the web browser ask user to refresh the page.
The other problem is about export excel functionality.
[code]
<af:commandImageLink text="" id="cil4" icon="/adf/images/excel.png">
     <af:exportCollectionActionListener type="excelHTML" exportedId="t2"/>
</af:commandImageLink>
[/code]
In Glassfish, clicking on the export excel button raise a nullPointerException. This nullpointerException does not occur if the usesUpload property is set to false.
Knowing that there is no problem in weblogic, how can I use af:inputFile and af:exportCollectionActionListener components in an application which must be deployed on Glassfish? Is there a solution? or is it an ADF Essential's limitation?

Answer 1

used the same code for the export to excel on 11.1.2.3 of adf-essentials deployed to Oracle GlassFish Server 3.1.2.2 (build 5)
<af:menu text="My Options" id="m2">
<af:commandMenuItem text="Export to Excel"
id="cmi1">
<af:exportCollectionActionListener type="excelHTML"
exportedId="t1"/>
</af:commandMenuItem>
Found no issues. Will give the inputfile a shot and let you know what I find.
