EJB invocation from Servlet with local interfaces

Hi all,

Today we handle all JSP/Servlet processing in an a separate engine. Theses
means the all EJB calls are performed using IIOP in a inter-process fashion.
If we would move the JSP/Servlets into the EAServer container I guess that
we could switch to local interface.

Are there any figures available on performance enhancments with this config?

Lars:

You don't need to use local interfaces, you have LWC.

Light Weight Calling (LWC) reduces the call cost on remote interfaces to
the point where they pretty much equal local interfaces. The only thing
you must do to implement LWC is turn it on, and then generate new stubs
and skeletons (since most of the LWC code is in the stub/skeleton
framework). And LWC works with remote interfaces, so you don't need to
modify your code.
