REST WebService and concurrency in java

I'm going to write a simple REST web service to download files from the server (simple GET method) The question is, should I handle concurrency in this situation, or is the web server going to do this?

It depends on what you mean by "handle concurrency". Do you need to write code to create threads for every incoming request? No, Jersey will create a new thread for every request before it calls your API method. Do you need to worry about admission DELETE

when someone else is GET

in the file? Yes.

Hmm, a bit of a vague question, but:



  • How do you implement the REST service using JAX-RS?
  • Depends on the server you are running it on.
  • What do you mean by "handle concurrency"? Since REST is stateless, concurrency shouldn't bother you.

If you only use local variables of the method, the match is not a problem (the container handles this).
