I want to have a form where user selects multiple zip files using checkbox and then clicks download button. Here I want to download all selected files. How to implement this? I can download single file using stream result type but I have no idea how to use stream result type to download multiple zip files with one user click.

Can anyone please guide me on this?

You can't download more than one file in an HTTP response. That's a design feature of HTTP. And since Struts is sending out HTTP responses, you can't do that in Struts.
