It is quite simple as you can see, but the String I am saving here:
this.httpSession.setAttribute("name", name)
Can never be retrieved here as long as it is always null:
this.httpSession.getAttribute("name") != null
I debugged the code, and you can retrieve the string inmediately afterwards of the set. However, when it reaches the other method, it won't work at HttpSession object changes. (It even has another ID)
What can be the problem? Thanks
Assuming other handler(getEnemies()) when you meant other method
Yes the object changes since they both are different rest calls which run on different threads. I'm not sure what could be the root of HttpSession object which you have injected but what ever you are storing in it might not be persistent( probably local to that Thread). That is what making you to get null value in the other method.
