To be honest, I'm not sure exactly what the Struts framework is using to
manage the file uploads. I simply create a FormFile member in my
ActionForm and it gets populated correctly with the uploaded file data.
Is this a parameter I can configure within Struts? Is there a feasible
replacement should this be the culprit?
many thanks,
Collin

Collin,
are you using
org.apache.commons.fileupload.DiskFileUpload.parseRequest(request)
?
I'm not sure anymore if this is wrapped by struts or not, but I guess it
is and it's this bit that isn't working.

Hello All
Any ideas on this one? I switched to a manual validation, which
works, though I'd much rather use the built-in mechanism to validate
where possible.
thanks

Hello!
I'm using struts-1.2.7.
I have form that needs both file upload functionality as well as
normal form fields interspersed on the same HTML page. I'm using the
built-in struts file upload utilities, so I create the form:
<html:form method="POST" action="/entity/submitfile.act"
enctype="multipart/form-data">
...
</html:form>
If there are no errors, this approach works perfectly. I correctly
receive the file data submitted, if any, along with the normal form
field values.
However, if my ActionForm fails validation, when the resultant action
gets called (specified by the input attribute) the request object
contains no request data from my form. My ActionForm, however,
populates correctly.
I understand that for multipart/form-data encoding types that the
framework will wrap the normal request object in a
MultipartRequestWrapper. Indeed, this is the case when this form
submits. The MultipartRequestWrapper does not contain any of my
request parameters from the form. I called
MultipartRequestWrapper.getRequest() to get the original request that
was wrapped to begin with, but it also does not have any of my
request parameters.
The strange thing is, is that if I convert the form to not be
multipart/form-data encoded, and remove the file upload widget, it
works perfectly, retaining request parameters even when validation
fails.
Any ideas on what I may be doing wrong? I feel like this is probably
a common problem. I found some similar problems on the mailing list
archives, but could not find any resolutions.
