How can I directly without saving the file on 2nd server download the file from 1st server to client's machine? So basically what I want to achieve is to allow the client to download a file from 1st server using the REST service on 2nd server since there is no direct access from client to 1st server using only data streams so no data touching the file system of 2nd server.
Which one is the more efficient? I'm not sure, but the returned InputStream s are different classes, so you may want to look into that if you care to.
So most of the answers you'll see in the link provided by GradyGCooper seem to favor the use of StreamingOutput. An example implementation might be something like.
But if we look at the source code for StreamingOutputProvideryou'll see in the writeTothat it simply writes the data from one stream to another. So with our implementation above, we have to write twice. How can we get only one write? Simple return the InputStream as the Response. Client objects are expensive resources.
You may want to reuse the same Client for request. You can extract a WebTarget from the client for each request. I think the WebTarget can even be shared. I can't find anything in the Jersey 2.
So I'm guessing Jersey 2. You don't have to make use of the Client API. A download can be easily achieved with the java. But since you're already using Jersey, it doesn't hurt to use its APIs. The above is assuming Jersey 2. For Jersey 1. I'm such a dufus. So the final solution for this particular use case was for the OP to simply pass the OutputStream from the StreamingOutput 's write method.
The point of the downloadFile method accepting an OutputStream is so that it can write the result directly to the OutputStream provided. For instance a FileOutputStreamjava rest service download a list of files, if you wrote it to file, java rest service download a list of files the download is coming in, it would get directly streamed to the file.
It's not meant for us to keep a reference to the OutputStreamas you were trying to do with the baoswhich is where the memory realization comes in. So with the way that works, we are writing directly to the response stream provided for us. The method write doesn't actually get called until the writeTo method in the MessageBodyWriterwhere the OutputStream is passed to it.
You can get a better picture looking at the MessageBodyWriter I wrote. You can see the link I provided in the earlier part of the answer, where I link to the StreamingOutputProvider. This is exactly what happens. Pseudo code would be something like this there are a few other similar options in above mentioned post :. Learn more. Asked 4 years, 11 months ago. Active 14 days ago. Viewed k times. I have 3 machines: server where the file is located server where REST service is running Jersey client browser with access to 2nd server but no access to 1st server How can I directly without saving the file on 2nd server download the file from 1st server to client's machine?
It will work this way? StreamingOutput did the trick. Thank you peeskillet! Many thanks! Pritam Banerjee Alex Alex 2, 3 3 gold badges 26 26 silver badges 42 42 bronze badges.
