RE: Remote vs Local Method Call Optimization
Hi Robert how do you know this ? Also how does orion do this, will it just call methods normally in java when the Entity Beans are local. cheers -Original Message- From: Robert Krueger [mailto:[EMAIL PROTECTED]] Sent: Sunday, November 05, 2000 7:08 PM To: Orion-Interest Subject: Re: Remote vs Local Method Call Optimization At 17:54 05.11.00 , you wrote: Hi Does anyone know if local/remote method calls from EJB to EJB are optimized on Orion.

I asked the orion guys 2. how else could it be that fast? 3. output of getClass() you'll get the wrapper class name that contains all the local stiff like db operations etc. Also how does orion do this, will it just call methods normally in java when the Entity Beans are local. it should at least keep pass-by-value semantics (i.e. deep-copy all parameters of bean invocations), otherwise it would violate the specs. however, I never really checked. robert cheers -Original Message- From: Robert Krueger [mailto:[EMAIL PROTECTED]] Sent: Sunday, November 05, 2000 7:08 PM To: Orion-Interest Subject: Re: Remote vs Local Method Call Optimization At 17:54 05.11.00 , you wrote: Hi Does anyone know if local/remote method calls from EJB to EJB are optimized on Orion.
