About CORBA::Object::Helper::bind() function on ACE_TAO 5.4

[revtheundead]

Hello,

I'm part of a project that uses ACE_TAO 5.7. There is a function call to CORBA::Object::Helper::bind() somewhere in my code that looks a lot like this:

//...
CORBA::Object* temp_ref;
Hotel_var the_hotel;

// Bind to Hotel Server
TRY{
    temp_ref = CORBA::Object::Helper::bind
    (
        "",                      // server class
        "Hotel_Server",          // server instance
        "RootPOA",               // POA name
        "",                      // object id
        argv[1],                 // server endpoints
        Hotel::oe_IR_Name,       // repository name
        true,                    // pre-connect to server
        true,                    // verify location
        _env                     // environment
    );
}
CATCH(CORBA::SystemException, sys) {
    cerr << "exception raised in bind" << endl;
    return -1;
}
ENDTRY(-1);

the_hotel = Hotel::_narrow(temp_ref);

//...

However, there is no member named Helper inside Object and therefore no bind method in ACE/TAO 5.7. I wanted to know how I can migrate the above code segment to ACE/TAO 5.7. By the way, the endpoint here apparently has the form ipmc://<ADDRESS>:<PORT>.

I realize with newer versions of ACE/TAO coming out these may be rather ancient versions but it would really help if I could learn more. I have tried to look this up in the ACE/TAO changelogs but nothing useful comes up and I have little to no idea where bind()'s counterpart may be.

Thanks in advance.

Which version of TAO was used the last time the CORBA::Object::Helper code compiled? Are you sure it was TAO and not another ORB?

Was the subject line of the issue meant to indicate that 5.4.x of ACE_TAO worked to compile this code? If so, that doesn't match what I see in this git repository for a 5.4.x tag.

There are many examples of activating a CORBA servant in the current version of TAO, maybe start with TAO/tests/Hello/server.cpp?

If you need more in-depth consulting to migrate your existing application to the current TAO release, please feel free to contact the company I work for at info@objectcomputing.com.

Hello @mitza-oci ! Thank you for taking your time to look at this issue. Unfortunately the project I'm working on is built on top of a very old project so I can't say much with 100% confidence but there doesn't seem to be a lot to suggest that some other ORB aside from TAO ORB was used here. Though, I would say that ORBexpress might have been used if TAO ORB usage seems unlikely.

As for the version: I'm confident that the code must have been compiled either with ACE_TAO 5.4.x or earlier. I can't exactly say how early but suffice it to say this project has its roots in the 90s.

Unfortunately, I don't know what this code segment is supposed to do so I can't look at any specific example. I have scoured most of the changelogs but I haven't found any entry or documentation explaining what it does.

It would also be good to point that I'm trying to migrate this code segment not to the latest version of ACE_TAO but instead to version 5.7.x (I can double check the full version if necessary) so the current documentation is not very useful to me at the moment.

5.4.x and 5.7.x are not significantly different from each-other or from the current release in this respect: they all implement the OMG standard CORBA 3.x spec.

All versions of TAO come with many examples of how to use it in the tests and examples directories. There are also good online resources that will apply to 5.7.x with very minimal differences.

Again, if you'd like in-depth expert help on this, we can provide that as part of our commercial services. The general policy in the GitHub community repo is that we'll try to help as best we can (as time allows) on the current version of TAO.

Very likely this code is coming from a different ORB, I can't find any reference to it within TAO.
