Hi All,

I have api endpoint called download  which need to download a zip file when you hit the api . currently I am reading the files using the file input stream and writing with zipoutput stream to temp location .Now I need to pipe the file input stream to response stream  in scalatra.

Currently Iam using 

Scalatra 2.6

Hi Mahendar,

Sorry for the late reply.

Scalatra supports InputStream as a result value of the controller.
https://github.com/scalatra/scalatra/blob/3db831f380ad0ff5d863eb6fa6d98beb8e366222/core/src/main/scala/org/scalatra/ScalatraBase.scala#L444-L447

Thus, simply returning InputStream from your controller should work.
Also, you can return File directly instead of InputStream.

By the way, we have an online chat room on Gitter.
There are some more active users and developers.
It might be better to ask there if you have any questions.

Naoki
