Please don't reply to this mail. I have solved issue and it work the way I
expect. It is surprising that in case of file upload JQuery's Form Plugin is
not picking form's action attribute value and request was not reaching to my
action class. When I explicitly pass url's value to ajaxForm("options")
like below then request reaches action class and everythings works perfectly
for me. May be it has something to do with iframe, as my other ajax forms
work fine.
$('#myPhotoUploadForm').ajaxForm({
url: 'myPhotoUpload_upload.action',
Thanks...
