How many sessions can be managed by an Java Application in Struts 2?

Question

I am working on Transaction Management application, and I am using Struts2. I have used internally a session for setting and getting values like

ActionContext.getContext().getSession().put("string", string);

Is there any limit or any disadvantage of using a session like this in the application?

Answer 1

Limit is the size of your computers physical memory.you dont store dynamic values in session because someone can modify them in the meanwhile , so store only those values in session which represent any user specific data or static values (i.e. which are not going to be changed while session exists).

Note : static here is not static keyword .
