what EJB stubs do you have in mind as you don't need any stubs to call ejbs.
Do you maybe have web service stubs in mind?
No. I'm referring to EJB client stubs.
I'd like some additional clarification about what you're claiming here. I've seen some indirect mentions that JBoss EAP generates a dynamic proxy at runtime instead of using client stubs. That wasn't a very concrete or reliable source. I just sat through a webinar on JBoss EAP from some relatively authoritative people who said that we had to generate EJB client stubs manually.
If you had been using EJBs for many years, as I have (although very rarely recently in recent years), you'd know that what you're claiming here is at least too strong. It may be the case that very recent versions and implementations can avoid requiring client stubs, but certainly not "you don't need any stubs to call ejbs".
If you can cite clear documentation that describes this, I'd appreciate it.
