Hi All,
I have one problem, I have one scenario where i have <html:file> which must be uploaded and processed. Once the processing is done i need to show the result on a pop up screen. On click of the popup i must show the file upload screen.In this case i need to submit the form as i have to pass the formFile object to the action class and at the same time open a popup on click of <html:link>. Can any one help me to solve this issue. I will be thankful.

Thanks in advance
