REST WebService and concurrency in java

I'm going to write a simple REST webservice for downloading files from server( a simple GET method) The question is: Do I have to handle concurrency in this situation or the web server is going to do that?

It depends on what you mean by "handle concurrency". Do you have to write code to spawn threads on each incoming request? No, Jersey will create a new thread for each request before it calls your API method. Do you need to worry about a DELETE request coming in when somebody else is GETing a file? Yup.

Hmm, bit of a vague question but:

  • Depends on how 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 should be none of your concern.

If yo're using only method-local variables, concurency is not an issue (container handles this).
