JMS in Stateless Bean

Usually, We use ServiceLocator Pattern to Cach lookup of JMS connectionfactory, Queue etc. In EJB3, we can use DI to inject the resource as below in session bean. My question is, how does container do this injection? Does container use something like caching the lookup? Do we need to really worry about it?

Stateless beans are pooled so it wouldn't need to be repeatedly injected anyway, right?

Right. But let's say if the pool size 50, then in that case, the container has to do at least 50 lookup when more beans are needed, right?
