REST WebService and concurrency in java

Question

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?

Answer 1

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.
