问题 As a beginner of SLSB EJB, I understand that accessing them locally (through Local Business Interface) is more efficient than remotely. When an EJB is accessed through an Endpoint, is it being accessed remotely or locally? This is in the context of accessing the EJB through JAX-RS. 回答1: A webservice endpoint is neither local nor remote. It is its own client view. That said, the overhead from remote is primarily due to marshalling/demarshalling arguments for pass-by-value semantics of

Actually, i was trying to spawn 100000 threads to simulate a load on an EJB method i wish to test, and it seems not possible this way. Is there a way which i could achieve this? Or is it that i would need to have multiple machines in order to achieve that load. Is
