zipping files for download
Hello:
I started writing a Struts 2 action which zips up the contents of a
directory on the filesystem and downloads it. Everything was fine until
I discovered that java.util.zip.ZipOutputStream requires an OutputStream
in its constructor. It doesn't seem like a good idea to get a reference
to the ServletOutputStream in my action and then use StreamResult later
on (if that is even necessary). On the other hand, I could do the
zipping within a custom result but this also seems inappropriate. The
ideal solution would be to have a custom result which somehow receives
from the action some type of object which contains Files in a tree
hierarchy. I don't know, I'm new to Struts 2 so any feedback on this
matter would be appreciated.
Regards,
Eric Hamacher

I said :
"The ideal solution would be to have a custom result which somehow

I did just that. I invented an object "Directory" which holds files and
other "directories". My action assembled this object. My result took
the object, recursed through it, and created a zip to stream.
Thinking out loud, I guess.
