[teiid-designer-dev] [teiid-dev] Teiid In JCA Container

[Ted Jones]

Ramesh,

Up until now, Van and I were under the impression that Teiid discovery in 6.3 for Jopr (Teiid Console) may and likely WOULD change, but the core functionality made available through the Admin API would not. Based on this thread it sounds like both discovery and configuration will be completely different. Instead of doing a lot of work on the console that will get tossed, we need to put the Teiid console development on hold until all the design decisions are made regarding deployment and configuration of Teiid for 6.3. We need to be included in any decisions made regarding the final approaches. Also, Van and I can be used as resources for implementing the configuration approach which will allow us to more easily add the necessary hooks to the Teiid Jopr plugin.

Thanks,
Ted

Feel free, we should have this discussion on the Teiid design forum
really...

Ok.

People have different definitions of embedded ;)

Different concepts.

A MC bean is just a Plain Old Java Object (POJO) managed by the JBoss 
Microcontainer. The MC projects provides various APIs/SPIs to do
integration.

Profile Service handles "profiles" of a server -- e.g. "give me a 
configuration with logging, naming, transaction, jca, messaging and
ejb3". The profile service selects the MC beans that will provide such a
profile.

Lead: Emanuel Muckenhuber (and Scott Stark)


@ManagedObject identifies POJOs which have a management view - they
don't have to be registered as MC beans.

@ManagedObject <-> MBean is handled by a 'bridge'.

You'll need various layers to deal with container (and kernel) specific 
details - in order to run on various EE servers.

When Teiid is running as part of the JBoss Application Server it should
use Profile Service) Create the server configuration for the Teiid
platform @ManagedObject) To identify management objects Other servers
uses other mechanisms. You'll have to evaluate each technology before
you bring it in - "do I want a hard dependency on this project ?", "do
the project have the performance profile we need ?", ... Good idea is to
use 

 http://jboss.org/tattletale/

to get an overview of the projects you are working with - yes, that was
a shame-less plug ;)


I keep the documentation for JBJCA up-to-date for each release here:

 http://docs.jboss.org/jca/

But *note*, that certain parts of JBJCA != JBossAS... and there is
still 
development to do before the first stable release.
