Thanks for your response Lachlan Deck.
You are right! I can use context().request().formValues(), but as I
said in my earlier email, I get image data from request which I cannot
read from context().request().formValues() and is only available by
iterating over WOMultipartIterator API. Hence, it is must for me to
grab request data using WOMultipartIterator API.
---------------------------------------------------------------------------------------------------
>From WebObjects API:
- public class WOMultipartIterator
- extends java.lang.Object
This class represents the content of a multipart/form-data HTTP
request.
You get the iterator for such a request by calling multipartIterator
on the WORequest object. Once you have this object, you get WOFormData
objects by repeatedly calling nextFormData, until it
returns null.
Each WOFormData allows you to introspect the sub-headers, as well as
either look at the form value(s) or grab the entire content of the part
as an InputStream subclass.
The InputStream subclass is a WOFormDataInpuStream and can be used to
stream large file uploads to disk (or elsewhere).
The WOMultipartIterator should NOT be used with WOFileUpload
component actions. It may be used with component actions where there is
no WOFileUpload, and it may be used in DirectActions.
---------------------------------------------------------------------------------------------------
>From above API, I get to know I can use WOMultipartIterator API in
either component actions/ direct actions.
Thank You

I would like iterate through this api, and
retrieve form key-value pairs for my business logic processing.
Basically I use a third party UI interface which obviously sends the
data across to the server encoded in the HTTP Request and this data has
file data to be uploaded.
context().request().formValues()
So, can I iterate through WOMultipartIterator
API in WOComponent action methods and retrieve data from this api.
I don't see why not. That's what the api says.
with regards,
