Dummy's guide to writing new component types

[Srikanth Bhattiprolu <bs...@gmail.com>]

How do i go about writing a new component type, i dont want anything fancy
might be just all System.out statements to the console but i want to go
through the flow as described in the programming model. I was trying to
understand this using the Javascript implementation but hadnt been able to
make much progress. How do the builders, model, loaders etc fit together. So
basically am looking for a beginner's guide to a new component type .. is
there any document describing that right now.

Nice! If you create a JIRA issue for this and attach the code to it, 
we'll take a look. If you have a maven pom.xml or a list of the 
dependencies, please don't hesitate to attach it too, it will help us 
build it.

Also if you have any questions or ideas to further improve our 
extensibility story (how you contribute an extension, the APIs you had 
to use etc.), please feel free to ask, start a discussion on the dev 
list or contribute more code. Meeraj who contributed the groovy 
container had some good suggestions in that space (need to find some 
time this weekend to look into this, the last few days I've been very 
busy with our M1 work and preparing for JavaOne). It would be nice to 
start a discussion on the dev list on our container and binding 
extensibility story and collect thoughts from all the people who have 
contributed various containers or bindings.

Thanks!

I know that i vanished after asking you for all the info. I got real busy
with my office work and never got a chance to try the steps you wrote here.
Apologise for that.

Anyway the reason i started all this was to have a Ruby container for SCA
using JRuby which has a BSF implementation for Ruby. So i saw the new Groovy
container that was created - so i just took the complete code, changed all
the references of Groovy to Ruby, added about 5-10 lines of code and i have
a sample Greetings script running with Tuscany.

Didnt get a chance to go through all the docs yet, as i was busy with some
other things. Will try to read through and send in comments tomorrow.

Yup. We can go with the Javascript implementation.

We have the JavaScript implementation and I was thinking of basing the
documentation around that one - would that work?

For new ones we should set up a page where we can list extensions that
people would like to see added. From the component type side I have
heard requests for XSLT, BPEL and Spring support; from the binding side,
JMS, JAX-WS and JAXB.

Sure, i can help with that. Will even use your steps to write a dummy
implementation so that i can get something concrete out of it. Do you have
any scenario in mind that we can use to write up this document. How about a
simple scripting language with a few constructs and see how we can develop
the component type for that.

There isn't yet but the top item on my to-do list is to clean up and
/document/ the APIs needed to do things like this. I would really
appreciate any help that you can give in this process.

There are three things that a component type implementation needs to
participate in:
* model loading
* context building
* handling runtime invocations

I plan to get a first cut of the documentation for model loading up on
the wiki over the weekend with the others to follow soon after. If you
are willing to review, ask questions and even update the documents it
would help greatly.
