This was from the IBM sample 287 test. Given the design goal of having an application be as robust as possible, which techniques should the developer AVOID using in the design: A) Use persistent HttpSessions to manage application state data. B) Use stateful session EJBs to manage application state data. C) Make references to node-specific resources. D) Make all resource references via java:comp/env JNDI references. Any help on this would be much appreciated.
Given the design goal of having an application be as robust as possible, which techniques should the developer AVOID using in the design: A) Use persistent HttpSessions to manage application state data.
Avoid based on the fact that HttpSession data is only available for HTTP clients?
B) Use stateful session EJBs to manage application state data.
This should be ok.
C) Make references to node-specific resources.
Avoid for the obvious reasons.
D) Make all resource references via java:comp/env JNDI references.
