How to Send & receive HL7v2.3 & HLv2.5.1 message from same port.

Question

Hi,
Currently I have a requirement of sending multiple version HL7 messages say HL7v2.3 & HLv2.5.1 from the same port(say 3333) and receive it at the same port (say 4444) using Oracle SOA Suite.
To address this problem, I first tried to create multiple versions endpoints in the Healthcare UI of SOA and gave them separate Composites each catering different versions of the HL7 message structure. But this didn't work since, the Healthcare UI refuses to accept two different Composites. Not sure if this supported in Healthcare UI or not?
Also, another problem which this approach threw at me was that I have another challenge to create a single healthcare adapter to accept both versions which is not possible, i think, because when we are creating the HL7 adapter in the Composite it asks to provide the HL7 structure it follows and there can be only one message structure that I could provide to this healthcare adapter placed at the receiving end.
With extensive googling I was pointed out to second approach of making it entirely in B2B. But there was also stuck at the time the agreement (Agreement between local partner and remote partner for both the HL7 versions) was to be deployed, since it was giving this error.
Agr1 is not valid. Please correct the following errors.
Error -: B2B-52276: Type of the parameter MessageECSFileBlob must match with the value {1}
On my part I tried to investigate what this MessageECSFileBlob is?
And the answer I got is that it is part of Document Definition and is  "Absolute file path of ecs".
My Take & Confusion Around this::
1. Since I first tried to cater this problem through Healthcare UI so, I have imported the repository for both the versions HL7v2.3 & HLv2.5.1. Now since the B2B shows all the HL7 versions, therefore I didn't create any custom message structure for this since the entire HL7 version repository is already available to me.
Do I need to remove these versions from the repository and come back to B2B to first provide it custom message structure for both HL7v2.3 & HLv2.5.1?
2. Any idea if one endpoint can support multiple message structure with different composites in Healthcare UI?
Thanks

Hi citbcj,
You could "fix" by catching and handling the exception. Here's the pseudo code
declare
  exception   smtp_error;
  pragma exception_init (smtp_error, -29279);
begin
  for rec_notify in cur_notify loop
    declare
      l_to   varchar2 (100) := rec_notify.email;
    begin
      html_email (l_to, l_from, l_subject, 'none', l_body);
    exception
      when smtp_error then
        log_it_or_something_and_continue;
    end;
  end loop;
end;
