Servlet REST API and thread data exchange

What is the best and simplest way to organize data exchange between servlets and thread? So I have (designing) a thread that manage some process and I have REST servlets that allows to query status and update them also. I am not going to expect too many REST calls, probably one in a second, so I can use synchronized to avoid multi-threading issue.

I suppose that will be able to create a new bean that will run a thread inside it. But how to access it through servlet and have some shared object between them? What's are the problems with this solution?

You have not put many details so its rather hard to answer exactly what you need. First of all - you need to decide if old/good servlets are needed for you, or your functionality can start somewhere in controller with @RequestMapping annotation (if you use spring mvc).

You may want to use session scoped beans to keep any state between REST calls, maybe with mix with ThreadLocal property - please take a look at http://java.dzone.com/articles/painless-introduction-javas-threadlocal-storage thread local explanation.

If still confused -please share more details what exactly is this app going to maintain.
