Hi,
I want to upload file on server from stand-alone application (using
HTTPURLConnection). But when I run stand-alone application which uploads file,
I get following exception on server:
-------------------------------------------------------------------------------------------------------------------------------------------
WARNING: Parameters: Character decoding failed. Parameter skipped.

It seems struts2 filter tries to retrieve parameters from request. I am
directly writing file content which are byte array on output stream of url
connection.
One workaround I found is to bypass the upload request from struts2 filtering.
But this approach is not good because my entire web application is struts based.
Is there any way to upload file through strut itself?
Thanks,
Rupesh
