Unable to download attachment in corda

Trying to download an attachment from a corda node using rpc client:

@GetMapping("/download/{hash}")
fun download(@PathVariable("hash") hash : String) : ResponseEntity<Any> {
    return try {
        val input = SecureHash.parse(hash)
        val file = ZipInputStream(rpc.proxy.openAttachment(input))
        ResponseEntity.status(HttpStatus.OK).body(file)
    }catch (e: Exception) {
        ResponseEntity.status(HttpStatus.BAD_REQUEST).body(e.message)
    }
}

The out put from above code is:

{
   nextEntry: {
         name: "11.c",
         crc: 2689263033,
         size: 675,
         method: 8,
         extra: "VVQJAAN22XNb2EuCW3V4CwABBOgDAAAE6AMAAA==",
         comment: null,
         time: 1534318966000,
         lastAccessTime: { },
         creationTime: null,
         compressedSize: 332,
         directory: false,
         lastModifiedTime: { }
    }

}

But I am not able to find any downloaded zip, if it is downloaded i don`t know in which directory , Inside zip there is a pdf file I want to download it locally and open it.

openAttachment returns an input stream, rather than causing the attachment to be downloaded to somewhere on your node.

You need to take this input stream and save it as a JAR file, which you can then unzip to access the PDF.
