DOES THE PROBLEM AFFECT:
EXECUTION: ORB Initialization
SYNOPSIS: Can omniORB and TAO coexist in the same process space?
I evaluate how to port a rather big CORBA system using omniORB
to TAO. Because it's a rather complex system, I started with porting one
CORBA servant object. It was no big efford to make the changes to compile
and link the code for TAO.
I then tried to integrate this one TAO object into the omniORB system.
This system however loads CORBA servants from a shared libraries.
The whole mechanism to find and load these needed libraries, includes
CORBA calls (which are still served by omniORB CORBA servants).
As a concequence to this I end up initializing TAO and registering
the object within a CORBA call served by omniORB (see attatched
coredump.txt), which seems to lead to a coredump.
More specifically said, the registration of the servant object within
the POA, using the _this() method seems to mess up everything.
Does anyone have some hints for me, if it is a bad idea in general to
use TAO and omniORB in the same adress space. Or might the nesting of
TAO servant registration within the processing of omniORB be a problem?
Maybe someone familiar with the TAO POA can comment on what exactly is
going wrong, by having a look at the coredump stack?
