Every client either needs a permission or the method is freely accessible to all.

All JEE components such as EJBs and Servlets can make use of resource injection.

Only 1 servlet instance can response multiples requests, that no make multiples request to only unique EJB?

I am sorry, I did not understand your question.

if inject using resource injection, the injected resource not will be used to all requests responsed by this instance of servlet?

Yes, it will be used to service all requests by that instance of the servlet.

It must get a reference to the Queue using JNDI lookup if it is a standalone client.

Can client client a Queue manually using JMS API ?

Not sure what you mean. To get a reference to any resource, you need JNDI lookup (or injection by the container but in a standaalone client there is no container).

Explanation says : "It must get a reference to the Queue using JNDI lookup if it is a standalone client."

Standalone client can create a JMS Queue or Destination object, there is no requirement to get a reference to a queue using JNDI lookup.

Well, first of all, Queue is an interface, so, you can't do new Queue(). Therefore, your example Queue q = new Queue("my.queue"); is wrong.

Second, the problem statement is about getting a reference to a queue. Not creating a Queue.
