CORBA::MICO

Perl Interface to MICO (Mico Is COrba). CORBA Control Center, see subdirectory ccc for more information.

Status

Allmost all base client and server functionality is currently working. Quite a few things are left to be done. A few of them are:

• wchar and wstring types
• less frequently use ORB functions
• ValueBase operations, Policy object and so on
• IR object directly from ORB not from InterfaceRepository
• ... :-)

None of these are particularly hard to do given what works now - they just haven't been done yet.

Documentation

General information about a mapping of CORBA onto Perl is in the available in the file 'MICO/mapping.pod' while specifics about MICO are in 'MICO.pm'. Information about the internals of the module is in 'MICO/internals.pod' These POD documents can be viewed on the screen using the 'perldoc' program:

perldoc MICO/mapping.pod

or converted to a variety of formats, for example:

pod2html MICO/mapping.pod > MICO/mapping.html

They will also be installed as manual pages.

The file MICO/internals.ps is a diagram that may be useful for figuring out MICO/internals.pod.

Installation

To compile and run this package, you'll need to have MICO v2.3.5 or better installed. Information about MICO is availaible from:

http://www.mico.org/

You'll also need Graham Barr's Error module - available from CPAN in the directory:

http://www.perl.com/CPAN/authors/id/GBARR/

And a reasonable recent version of Perl. (This has been tested with perl5.6.1, and perl5.005_03)

Once you have MICO installed, to build this package, simply type:

perl Makefile.PL
make

The package then can be installed by executing the command:

make install

Trying it Out

To start the interface repository, load in the Account.idl interface file, and create an appropriate .micorc, run the script

./start-servers.sh

Run the Perl server program in the background:

perl -Mblib server &

And then run the client program:

perl -Mblib client

You should see output that looks something like:

(I need +99500.00 more)
created counter!
1 2 3 4 5 6 7 8 9 10
destroyed counter!
created counter!
Successful completion

Trying the GTK Demo

To use this demo you must have GTK installed on your system and the Kenneth Albanowski's Gtk module for perl (version 0.5 or later). Both are available from ftp://ftp.gimp.org/pub/gtk

Then, start up the servers with

./start-servers.sh

and run two copies of the 'tictactoe' program

perl -Mblib tictactoe &
perl -Mblib tictactoe &

Trying the CORBA Control Center

After installation simple run:
ccc

Note on the start-servers.sh

In actual operation, you probably wouldn't want to keep killing and restarting the servers (ird and micod) as this script does. But doing so when testing things out makes it a lot easier to make sure that the current test isn't being affected by previous test failures.
