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 StreamingOutputProvider , you'll see in the writeTo , that 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. Edit Profile. Sign Out View Profile. Over 2 million developers have joined DZone. This article demonstrates how to use a Spring Boot application and MySQL to maintain a database of uploaded files and their metadata.
