java - Guice Singleton and Servlet -

i'm using guice , have question. there servlet that's singleton. there 1 instance of class in jvm or 1 instance of session scope? , concurrency access class?

and make servlet single threaded confirm single memory space use, container lightweight. same concept available in spring default every bean singleton.
