Re: Forte and OrbixWeb call-back

Question

We have created a business process manager (BPM) layer between our client GUI
and business model objects that supports Java call-in/call-out. This enables
switching out the Forte windows with Java windows for a web solution with
minimal code re-write.
We were able to get most functionality to work as per our design, which
included registering a call back function from a Java GUI in the BPM, but had
to make some sacrifices due to a Forte bug, at least under 3.0.D. We turned
in case #38434, detailing errors when we tried to fire a callback method with
parameters, example below ("callback" was the Java object passed in.)
method TestIIOPBackend.FireCallback(input message: Framework.string)
begin
if callback != nil then
task.part.logmgr.putline('Firing callback');
//WORKS
callback.CallMe();
//ERROR!
callback.CallMeString(message);
else
task.part.logmgr.putline('Callback not set');
end if;
end method;
This may have been fixed in 3.0.F, we found a way to work around it in our
design and haven't investigated since.

Has anyone actually tried the tech note 11153 "Java call-in/call-out and
Forte
Anchored Objects"? I'm trying to verify the callback mechanism from
Forte to
an IIOP Java client. Thanks.

Answer 1

Peggy,
1) Do you have experience with PowerBuilder and Forte' applications running at
the same time on the same (laptop) computer? Here I'm thinking
about any potential resource constraints? Memory Requirements?As log as you are using Win95 or NT you should not be concerned about WIN-resources. Memory depends more on what your 2 tier PB application requires than what your Fort&eacute; would require.
Cheers,
Troels

2) Can PowerBuilder and Forte' applications call and interact with one
another?
The Forte' application will need to interact with the PowerBuilder application
to pull out information maintained by the PB application.
