Call RemoteHome in web component

[Alan A Smith]

HiHi,

Please help! Something I'm confused.
I packed the ejb(s) and .war files in a .ear file.
If the web-component call the ejb through remote home method instead of local home mehotd, will it affects the performance?
Because of ejb and war are pack in the ear file, I think weblogic will handle all the components(servlet and ejb) in the same JVM then the method is call by reference instead of call by value. Is this true?

Regards,
Alan

Hi karthik,

Thx a lot. I've another question.
How about I call ejb through local host.
Weblogic will use pass-by-reference automatically even not enable <enable-call-by-reference> in weblogic-ejb-jar.xml ??

Alan,
To answer your question,

Quoting from WL Docs:

"Method parameters are always passed by value when an EJB is called remotely".

If you set call-by-reference to true for an ejb but you end up accessing it remotely, weblogic makes sure that it will pass method paremeters by value.

But if you access the same ejb locally, it will make sure that it uses pass by reference.

So it is better that you set call-by-reference to true to get better performance.
