[jira] Updated: (TUSCANY-2397) Binding corba should use a
host-corba module
[ https://issues.apache.org/jira/browse/TUSCANY-2397?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Wojtek Janiszewski updated TUSCANY-2397:
----------------------------------------
Attachment: host-corba-jira-2397-25th-june-2008.patch
Here's host-corba module implementation. It does: registering, unregistering and getting references to CORBA objects. It's not what you really wanted, but it should unblock path to further CORBA binding module development.
Maybe I'm getting you wrong, but I understand that some orbd instance should be spawned. We cannot easily run orbd from JDK - there is indeed com.sun.corba.se.impl.activation.ORBD but as far as I can see it cames without any Javadoc or support.
I'm also bit confused about http-host, http-jetty and http-tomcat - how and when appropriate module (http-jetty or http-tomcat) is beeing choosed and connected to host-http interface?
I'd appreciate any comments and clues.
Thanks,
Wojtek

Maybe it could just be responsible to create the ORB instance. Then we can
push more logic into the shared corba runtime.

It will be based on the META-INF/services/... file for the CorbaHost
registration. Only one host should be made available for discovery.

You can experiment the annotation-based approach. But I would rather that
you get some integration scenarios working first as I described in the other
thread.

Re: [jira] Updated: (TUSCANY-2397) Binding corba should use a host-corba
module
Posted by Wojtek Janiszewski <wo...@gmail.com>.
It looks clear for me now. So I assume that:
1. host-corba-? would be specific ORB providers
2. host-corba would contain logic to bind object, unbind object, get
reference basing on ORB obtained from host-corba-?
3. JDK CORBA would be default. How would user declare usage of different
CORBA implementation (so usage of another host-corba-? module)?
Could you also give me a tip where should I start to add this metadata
to map Java types to CORBA (the types are arrays, unions)?
Thanks,
Wojtek

Yes, CORBA provides a way to plug in ORB implementations using properties.
How we want to expose these property configurations? I assume the CorbaHost
can provide the value of these properties or it can create an ORB instance.

Raymond

But custom CORBA implementations can be plugged just by adding some
properties, why can't we go that way? Do you mean that specific
host-corba modules would set those properties?

Re: [jira] Updated: (TUSCANY-2397) Binding corba should use a host-corba module
Posted by Raymond Feng <en...@gmail.com>.
The main idea is to have the pluggability for different CORBA providers.
For example,
We could have host-corba to define the SPIs for other CORBA providers, then
we could potentially have:
host-corba-jdk: Use the CORBA implementation shipped by the JDK
host-corba-yoko: Use Yoko ORB
Thanks,
Raymond
