120. Stateless means there is no memory of the past. Every transaction is performed as if it were being done for the very first time. Stateful means that there is memory of the past. Previous transactions are remembered and may affect the current transaction. Stateless: // The state is derived by what is passed into the function.
2 nov. 2012 · 9. HTTP/2 is stateful. HTTP 1 is stateless. Later additions intended for HTTP 1, like cookies, added state. Those additions are not apart of the "core" HTTP 1 specification. This is why HTTP 1 is said to be a stateless protocol although in practice it is not. HTTP/2 on the other hand was designed with stateful components baked in.
Main difference between @RequestScoped vs @Stateless in this scenario will be that the container can pool the EJBs and avoid some expensive construct/destroy operations that might be needed for beans that would otherwise be constructed on every request. edited Aug 2, 2016 at 4:24.

12 avr. 2015 · 129. Stateless object is an instance of a class without instance fields (instance variables). The class may have fields, but they are compile-time constants (static final). A very much related term is immutable. Immutable objects may have state, but it does not change when a method is invoked (method invocations do not assign new values to fields).

10 mai 2009 · The advantages of stateless programming coincide with those goto-free programming, only more so. Though many descriptions of functional programming emphasize the lack of mutation, the lack of mutation also goes hand in hand with the lack of unconditional control transfers, such as loops.
20 sept. 2019 · Yes you can do this simply by passing the info to the constructor.

2 févr. 2011 · Stateful and Stateless are properties of EJB's (Java EE container managed session Beans), rather than anything specific to the JPA spec. A Stateful bean will have state associated with it for each request from the same client. Stateless beans have no client specific state and a single instance could be used concurrently, threadsafe, between ...
13. HTTP is stateless - this means that when using HTTP the end point does not "remember" things (such as who you are). It has no state. This is in contrast to a desktop application - if you have a form and you go to a different form, then go back, the state has been retained (so long as you haven't shut down the application).
I am using stateless to implement logic of a state machine in our application.We have an AcceptedFile state that has other inner (sub)states.The problem is I don't know how should I indicate initial inner state in my code so that when a machine transit to AccptedFile state it would also automatically transit to its initial inner state.Here's ...
